How to add products to a shipping profile in your Shopify store?

Go to Settings > Shipping and delivery > Shipping profiles, open or create a custom profile, and select the products you want to add from the Products section. A product or variant can belong to only one shipping profile at a time, so adding it to a custom profile automatically removes it from its previous profile.

What is the difference between a general and custom shipping profile?

The General shipping profile is Shopify's default profile and automatically applies to products that aren't assigned to a custom profile. A custom shipping profile is used when certain products need different shipping rates, zones, or fulfillment rules, such as fragile, heavy, or oversized items.

Can I offer free shipping for any selected products?

Yes. To offer free shipping only on selected products, add those products to a custom shipping profile and create a flat shipping rate with the price set to $0 or enable free shipping for that rate.

Does shipping increase when customers buy two products in different shipping profiles?

Yes. When products from different shipping profiles are purchased together, Shopify combines their applicable shipping rates and displays one total rate at checkout, which will make the final shipping charge higher.

Should I use flat or carrier-calculated shipping rates in Shopify?

Use flat rates when shipping costs are predictable, and you want a simple, consistent checkout experience. Use carrier-calculated rates when costs vary significantly by destination, package weight, dimensions, or delivery speed.

How Anua Unlocked 5X AOV Growth with iCart’s Smart Cart Features

delivery customization Challenges Solutions drive results Scale business delivery customization Challenges Solutions drive results Scale business delivery customization Challenges Solutions drive results Scale business delivery customization Challenges Solutions drive results Scale business Anua is a globally recognized Korean skincare brand known for its minimalist philosophy and focus on gentle yet effective formulations. Built on the idea of simplifying skincare routines, Anua develops products that deliver visible results while avoiding harsh or irritating components, making them suitable for sensitive skin types. Initially using a traditional full cart experience, Anua transitioned to iCart’s side cart solution in August 2025, to create a more seamless and engaging shopping journey. This shift allowed customers to easily explore complementary skincare products without disrupting their browsing flow, making it more intuitive to discover items that fit into a complete routine. By surfacing relevant recommendations directly within the cart, the brand enhanced product visibility across its range. Challenges Before implementing iCart’s side cart solution, Anua faced limitations with their existing full cart experience, which created friction in the customer journey. The traditional cart setup redirected users away from product pages, interrupting their browsing flow and reducing opportunities to explore additional products. As a skincare brand built around routines rather than single-item purchases, this made it difficult to effectively showcase complementary products and encourage customers to build complete regimens. Additionally, the lack of in-cart personalization and strategic upsell opportunities meant that customers were often unaware of related products that could enhance their skincare results. This limited the brand’s ability to increase average order value (AOV) and fully leverage its diverse product range. Anua needed a more dynamic and intuitive cart experience that could seamlessly introduce relevant recommendations while maintaining a smooth and engaging shopping journey. ❌ Cart Value Barriers Low average order value (AOV) due to single-item focus Most customers completed purchases with one primary product instead of building multi-step routines. Cart abandonment near shipping thresholds Customers were not clearly informed or motivated to reach free shipping or discount thresholds. Missed savings opportunities Customers were unaware of potential value in purchasing bundled routines or multiple complementary products. ❌ Absence of Progress-Based Incentives No free shipping or discount progress bar Customers were not motivated to increase their cart value due to lack of visible incentives. Missing tiered rewards system There were no structured milestones (e.g., “Spend more to unlock offers”), reducing upsell opportunities. ❌ Ineffective Cart UI/UX (Pre-Side Cart) Full-page cart disrupted shopping flowCustomers had to leave their browsing journey, increasing friction and drop-offs. No quick add/remove functionality Users couldn’t easily modify their cart or add suggested products without navigating away. Solution To overcome these challenges, Anua implemented iCart’s side cart solution to transform their traditional cart into a high-converting, interactive experience. By replacing the full-page cart with a seamless side cart, the brand ensured that customers could continue browsing while viewing their cart, significantly reducing friction in the shopping journey. Additionally, features like product recommendations & progress bars for free shipping and discounts motivated customers to increase their cart value. By combining personalization, incentive-driven messaging, and a user-friendly interface, Anua successfully turned their cart into a powerful revenue-driving touchpoint rather than just a checkout step. To maximize their cart effectiveness, they implemented two powerful features: ✅ Progress Bar with Multi-Reward Incentives Implemented a tiered progress bar to encourage higher cart value Customers are guided with a clear message like “Add $3.10 to unlock secret offer,” motivating them to continue adding products. Generated over $5M+ in revenue through incentive-driven cart progression Used product-based rewards to align with customer intent Instead of generic discounts, Anua incentivized purchases with relevant skincare items like Dark Spot Pads and mini serums. Built visual motivation for routine expansion As customers add products, they can clearly track progress toward unlocking multiple rewards, encouraging them to build a complete skincare routine. ✅ Product Recommendations Implemented “Frequently Bought Together” recommendations Customers adding a single product (e.g., toner) are shown complementary items like serums, moisturizers, or pads to complete their routine. Generated over 275K revenue through in-cart recommendations Encouraged full skincare regimen building Instead of isolated purchases, the cart suggests step-by-step product combinations aligned with common skincare routines. Increased product discovery at the final stage By surfacing relevant items directly in the cart, Anua ensured customers explore more of their catalog without leaving the checkout flow. Results Achieved in Last 180 Days 22932 Total Store Orders 45101 Total iCart Orders 5X iCart Generated AOV 65.70% Upsell Affected Conversion Rate These improvements reflect a clear shift in customer behavior on Anua’s store. Cart abandonment reduced as shoppers discovered complementary skincare products and felt encouraged to build complete routines. Engagement also increased, with customers interacting more with in-cart recommendations and exploring relevant product pairings.

A Practical Guide to Selling Jewelry on Shopify: Upsells & Post Purchase Tricks

Selling Jewelry on Shopify is one of the most practical ways to turn a creative product into a scalable online business. Jewelry is visual, emotional, gift-friendly, and highly personal, which makes it a strong category for ecommerce. But at the same time, jewelry buyers need trust before they purchase. They want clear product images, metal details, size guidance, return policies, secure checkout, and a shopping experience that feels premium. In this guide, we will cover the complete process of Selling Jewelry on Shopify, including store setup, product presentation, marketing, upsells, and post-purchase tricks that can help you get more value from every order. How to sell jewelry on Shopify Step 1: Choose a Clear Jewelry Niche Most competitor blogs start with niche selection, and for good reason. Shopify’s own jewelry business guide also lists finding a niche, researching trends, defining the brand, sourcing products, taking product photos, building the store, marketing, and scaling as core steps. Your niche helps customers understand why they should buy from you instead of another store. A general jewelry store can work, but a focused brand is easier to position. You can build your niche around: Minimal everyday jewelry Premium gold-plated jewelry Handmade or artisan jewelry Bridal and engagement jewelry Personalized name necklaces Men’s bracelets and chains Spiritual, cultural, or zodiac jewelry Affordable luxury jewelry Stackable rings and bracelets Gift-ready jewelry for birthdays, anniversaries, and weddings Many Shopify jewelry stores perform better when they sell around a lifestyle, not just a product. For example, instead of saying “We sell rings,” your brand can say “Everyday stackable rings for modern women.” That instantly creates a clearer customer image. Step 2: Build a Brand That Feels Trustworthy Jewelry is not an impulse product for every customer. Some products may be affordable, but buyers still care about quality, material, packaging, skin safety, durability, and returns. Your brand identity should answer these concerns before the customer asks. Create a strong brand foundation with: A clear brand story Consistent logo, colors, and typography Premium product photography Detailed product descriptions Easy-to-find policies Customer reviews Gift packaging details Care instructions Authentic product videos For jewelry Shopify stores, trust is part of the design. A clean homepage, elegant product cards, visible reviews, and a simple navigation structure can make the store feel more premium. Your brand should also define what makes your jewelry different. Is it handmade? Tarnish-resistant? Waterproof? Customizable? Ethically sourced? Gift-ready? Designed for daily wear? These details help customers justify the purchase. Step 3: Select the Right Shopify Theme Competitor blogs often include theme recommendations because jewelry stores depend heavily on visuals. A good theme should make your products feel premium without slowing down the site. BOGOS also includes themes, product media, collections, apps, homepage optimization, marketing, store examples, and FAQs in its Shopify jewelry guide structure. When choosing a Shopify theme for a jewelry store, look for: Large product image support Mobile-first product pages Quick view option Video support Product filtering Collection-focused layout Lookbook or lifestyle image sections Sticky add-to-cart Recently viewed products Cross-sell sections Fast loading speed If you are just starting, Dawn can work well as a free theme. For premium jewelry brands, choose a theme with stronger visual storytelling, editorial sections, and better collection layouts. The best Shopify jewelry stores do not overload the homepage. They guide customers through clear sections like new arrivals, bestsellers, gifts under a certain price, personalized jewelry, and occasion-based collections. Step 4: Create Product Pages That Sell Your product page is where trust and desire meet. Nivoda’s guide on Shopify jewelry sales recommends rich product descriptions that go beyond basic specs and include craftsmanship, stone quality, carat weight, origin, and care instructions to support both SEO and buyer confidence. For Selling Jewelry on Shopify, every product page should include: Product name with material or style Clear pricing Multiple high-quality images Short product benefit summary Metal, stone, plating, size, and weight details Size guide Care instructions Shipping and return details Warranty or guarantee information Customer reviews Gift packaging details Related products A weak product description says: “This is a gold necklace for women.” A stronger description says: “Designed for everyday layering, this 18k gold-plated necklace adds a minimal shine to workwear, party outfits, and casual looks. Its lightweight chain makes it comfortable for daily wear, while the gift-ready packaging makes it a thoughtful choice for birthdays and anniversaries.” The second version gives style, usage, occasion, and gifting value. That is what helps customers imagine the product in their life. Step 5: Organize Collections Around Buying Intent Do not create collections only by product type. Jewelry shoppers often search by occasion, price, material, and recipient. Useful collection ideas include: Rings Necklaces Earrings Bracelets Anklets Personalized jewelry Gifts for her Gifts for him Wedding jewelry Minimal jewelry Gold jewelry Silver jewelry Jewelry under $50 New arrivals Bestsellers Stackable sets This type of collection structure helps both users and SEO. It also gives you more opportunities to create targeted landing pages for paid ads and email campaigns. Step 6: Use Post-Purchase Tricks That Feel Natural Post-purchase upsells work because the customer has already trusted your brand. They have completed the hardest step: placing the first order. Now you can offer something that improves their purchase. Shopify’s developer documentation notes that thank you and order status pages appear at the end of checkout and can be customized using checkout UI extensions. Here are some post-purchase tricks for jewelry Shopify stores: 1. Offer Matching Products If someone buys earrings, offer the necklace from the same collection. If someone buys a pendant, offer the matching chain. 2. Promote Gift Packaging Jewelry is often bought as a gift. Offer premium packaging, greeting cards, or custom notes after purchase. 3. Add Jewelry Care Products Offer polishing cloths, storage boxes, anti-tarnish pouches, or cleaning kits. 4. Use Limited-Time Offers Carefully Countdown timers can work, but avoid making the offer feel cheap. Use wording like “Add this matching piece before your order is packed.” 5. Offer a Second Piece at a Small Discount For stackable rings or bracelets, offer a second piece with a small discount. This works well because stacking jewelry looks better in pairs or sets. 6. Promote Bestsellers If the original product does not have a perfect match, recommend a bestseller from the same price range. These small offers can turn a single-product order into a larger order without interrupting checkout. Use SellMore to Increase AOV After Checkout Once a customer buys jewelry, the buying journey does not have to end. This is where SellMore Post Purchase Upsell can be useful for Shopify merchants who want to increase average order value without disturbing the original checkout flow. SellMore helps merchants show upsell offers on pages such as the post-purchase page, thank you page, order status page, and checkout page for Shopify Plus stores. Sell More After Every Sale Show irresistible one-click post purchase upsells at the right moment that converts.

How to Reduce Returns on Shopify: A Complete Guide for Store Owners

Returns on Shopify are one of the quietest profit leaks in ecommerce. The sale shows up in your dashboard, you feel good for a minute, and then the refund request hits a week later. Shipping is paid both ways, the product comes back used or damaged, and the margin you thought you earned is gone. The good news? Most returns on Shopify are preventable. They come down to a few fixable things: unclear product pages, weak sizing info, delivery confusion, and a return policy that does more harm than help. This guide walks you through each lever, in plain language, so you can keep more of every sale you earn. Why Returns on Shopify Hurt More Than You Think A return is never just a refund. Every product that comes back carries hidden costs that stack up fast: Two-way shipping - you often pay outbound and return labels. Restocking labour - someone has to inspect, clean, repackage, and shelve it. Lost inventory value - around 40% of returned items can no longer be sold as new. Customer support time - back-and-forth emails, refund processing, and follow-ups. Lost trust - a bad return experience can stop a customer from buying again. Industry data from Shopify suggests reverse logistics now eats up around 30% of operational costs for many online stores. Cutting your return rate by even three or four points can free up serious cash you can put back into product, ads, or growth. The Top Reasons Customers Return Products on Shopify Before you fix returns on Shopify, you need to know why they happen. The numbers are surprisingly consistent across studies: The product did not match the description or photos Wrong size or fit Quality below expectations Changed mind or buyer's remorse Wrong item shipped Damaged in transit "Bracketing" - buying multiple sizes to keep one Did you notice something? Almost every reason on this list traces back to a gap between expectation and reality. Close that gap, and your shopify order return volume drops with it. 9 Proven Ways to Reduce Returns on Shopify Here are the nine levers that move the needle most. You do not need to do all of them at once. Start with the two or three that match your top return reasons. 1. Write Product Descriptions That Set Honest Expectations Most product pages are written like ad copy. They list features and lean on adjectives. The pages that actually reduce returns read more like an honest friend describing the product. Cover the boring details people actually care about: Exact measurements (length, width, depth, weight) Materials and what they feel like Care instructions and washing guidance What the product is not, or who it is not for 2. Add a Clear Shopify Size Chart to Every Apparel Product If you sell anything that has to fit a body, your shopify size chart is the single biggest return-reduction tool you have. Around 45% of apparel returns happen because of sizing alone. Fix that one thing and you can cut your return rate almost in half. A strong size chart does three things: Shows actual garment measurements, not just S/M/L labels Lists values in both inches and centimetres Includes a short "how to measure" guide with a visual The problem? Building a clean, mobile-friendly size chart in Shopify by hand is painful. You end up with broken tables on phones, ugly styling, or charts that do not update across products. This is where a dedicated table app makes life easier, you build the chart once and reuse it everywhere. 3. Set Clear Delivery Expectations Before Checkout A shocking number of returns are not about the product at all. They are about delivery. The order arrives late, on the wrong day, or after the event the customer needed it for. They do not want it anymore, so back it goes. Show estimated delivery dates clearly on the product page, in the cart, and at checkout. Let customers pick a slot when it makes sense cakes, flowers, perishables, gifts, and big-ticket items all benefit from this. 4. Use High-Quality Photos and Video From Multiple Angles One photo is never enough. Customers buy with their eyes, and when reality does not match the image, the product comes straight back. A solid product gallery includes: Front, back, and side views on a clean background Close-ups that show texture and stitching Lifestyle shots that show scale and context A short video (15-30 seconds) of the product in real use A Shopify guide on returns notes that user-generated photos and videos build the strongest trust because they show the product as buyers actually receive it. 5. Let Real Customer Reviews Do the Talking Reviews are the closest thing to a try-on experience your store has. Encourage them, sort them, and surface the ones that mention fit, quality, and use case. Make reviews work harder for you by: Asking for photo reviews after delivery Adding filters like "runs small" or "true to size" Highlighting reviews from people with similar body types or use cases Replying to negative reviews honestly, it builds trust 6. Improve Packaging and Quality Control Before Shipping Around 5-12% of returns are caused by damage in transit or the wrong item being shipped. Both are entirely within your control. Tighten the basics: Inspect every order before it leaves the warehouse Use protective packaging that suits the product weight and shape Double-check size, colour, and variant against the order Add a small "how to use" insert for products with a learning curve 7. Offer Exchanges Before Refunds When a customer wants to return, your first response should not be "refund issued". It should be "would an exchange work?" Save the sale by making exchanges easier than refunds: Offer free shipping on exchanges Provide a small store credit bonus (5-10%) for choosing exchange Suggest the next size or a similar product right inside the return flow Let customers swap colours, sizes, or variants without re-ordering Frequently Asked Questions 1. What is a good customer return rate on Shopify? Most Shopify stores see return rates between 17% and 20%. Apparel stores can hit 30-40%, while electronics often stay under 10%. A healthy target is to land below your category average and trend downward each quarter. 2. How do I check my return rate in Shopify? Inside your Shopify admin, go to Analytics > Reports and open the "Orders and returns by product" report. You can also calculate it manually: divide the number of returned items by the number of items sold in the same window, then multiply by 100. 3. How do I edit the order status page on Shopify? Go to Settings > Checkout > Order status page in your Shopify admin. You can add additional scripts, custom messages, FAQs, and post-purchase content. Many merchants use this space to add tracking widgets, support links, and upsell offers. 4. How can I reduce sizing-related returns on Shopify? Add a clear size chart with actual measurements, include a "how to measure" guide, surface fit-related reviews, and consider a size recommendation quiz. 5. What is bracketing and how do I stop it? Bracketing is when a customer buys multiple sizes or colours intending to return all but one. You can reduce it by offering strong sizing tools, accurate fit reviews, and gentle policy nudges like a restocking fee on multi-size orders. Final Thoughts Returns on Shopify will never hit zero, and that is fine. The goal is not perfection. It is reducing the avoidable ones. Start with the two or three changes that match your biggest return reasons. Add a size chart if you sell apparel. Rewrite your top product descriptions. Edit your order status page. Offer exchanges before refunds. Each of these small fixes compounds, and three months from now, your return rate will look noticeably healthier.

Shopify Functions: How The Latest Update Helps Merchants Customize

Shopify has completed one of its biggest checkout customization changes. Shopify Scripts stopped running on June 30, 2026, and Shopify Functions are now the main way to add custom business rules to carts and checkout. Merchants on any Shopify plan can use public apps built with Shopify Functions. This gives more stores access to advanced discounts, product bundles, delivery rules, payment controls, and checkout validation without asking merchants to manage code themselves. What are Shopify Functions? Shopify Functions are small pieces of backend logic that change how Shopify handles important parts of the buying process. A Function can tell Shopify to: Apply a discount when a cart meets specific conditions Combine several products into a bundle Hide an unsuitable shipping option Stop checkout when an order breaks a business rule Choose how an order should be routed or fulfilled The Function runs on Shopify’s infrastructure during the cart or checkout process. It receives information about the cart, applies the business rules, and sends Shopify a list of actions to perform. What is the latest Shopify Functions update? The most important current update is that Shopify Scripts are gone. Shopify stopped merchants from editing or publishing Scripts on April 15, 2026. All remaining Scripts stopped executing on June 30, 2026. Now merchants need to recreate rules using: A public app built with Shopify Functions A custom app using Shopify Function APIs This update makes the customization system easier to distribute and manage. Shopify Functions are packaged inside apps, and it follows a simple process: A customer changes their cart or moves through checkout. Shopify sends the Function the information it needs. The Function checks that information against its rules. It returns an instruction to Shopify. Shopify applies that instruction to the cart or checkout. For example, a merchant may create a tiered discount with these rules: Spend $100 and receive 10% off Spend $150 and receive 15% off Spend $200 and receive free shipping The Shopify Functions app reads the cart value and returns the correct discount. Shopify then applies it during the buying process. Functions run in a specific order. Cart transformations happen first, followed by product and order discounts, fulfillment logic, delivery rules, shipping discounts, payment changes, and checkout validation. This order matters when several apps are changing the same cart. What can merchants customize with Shopify Functions? 1. Product, order, and shipping discounts The current Discount Function API can create discounts across three areas: Products The complete order Shipping or delivery Use cases for merchants include: Tiered discounts Quantity breaks Buy X, get Y offers Customer-tag discounts Discounts for selected products or collections Shipping discounts based on cart value Discounts for products with custom properties This gives merchants more control than Shopify’s standard discount settings when the offer depends on several conditions. 2. Product bundles and cart changes Cart Transform Functions change how products appear and behave inside the cart. Apps can use them to: Merge multiple products into one bundle Expand a bundle into its individual components Add required products or services Change how bundle items are presented Build mix-and-match bundles Shopify allows Cart Transform apps on different plans. So check the app’s plan requirements instead of assuming every Cart Transform feature is available on every plan. 3. Delivery option customization Delivery Customization Functions can rename, reorder, or hide delivery options at checkout. A merchant could use these rules to: Hide express shipping for products that require preparation Place local delivery above standard shipping Hide delivery methods for particular customer groups Remove unsuitable options for specific addresses Prioritize a preferred delivery service Shopify currently allows up to 25 active delivery customization Functions on a store. Availability may still depend on the app, checkout surface, shipping setup, and the data available to the Function. 4. Payment method customization Payment Customization Functions control which payment choices customers see and how those choices are presented. They can help merchants: Hide cash on delivery for high-value orders Hide a payment option in selected countries Add payment terms for eligible B2B customers Send qualifying B2B orders for review Wallets such as Shop Pay, Apple Pay, and Google Pay have specific limitations. For example, wallets can be removed from certain checkout sections but cannot be reordered, and their branded names cannot be changed. 5. Cart and checkout validation Validation Functions prevent customers from completing an order when the cart does not meet the merchant’s rules. Examples include: Limiting the quantity of a high-demand product Requiring a minimum order amount Preventing incompatible products from being purchased together Checking a purchase order number Restricting purchases based on billing information Displaying an error message when a rule fails These validations run on Shopify’s backend. They can also apply to accelerated checkouts such as Shop Pay, PayPal, Apple Pay, and Google Pay. 6. Fulfillment and order routing Shopify Functions can help determine how an order should be fulfilled after checkout. A merchant may use them to: Prioritize a warehouse Prevent an order from being split across several locations Apply fulfillment restrictions Route orders based on stock, destination, or operational rules Choose a different fulfillment location for particular orders These features are useful for merchants with multiple warehouses, retail stores, and regional fulfillment centers. 7. Local pickup and pickup options Functions include tools for generating local pickup options, pickup-point delivery options, and local pickup charges. This can support cases where a merchant needs to: Generate pickup choices based on the customer’s location Provide pickup points from an external network Charge a fee for selected pickup services What is the Shopify Functions app? A Shopify Functions app is an app that includes one or more Shopify Functions. The app developer writes the backend logic and creates a merchant-facing interface for configuring it. The merchant can then install the app and create rules without editing the Function’s source code. For example, a discount app might allow a merchant to choose: Eligible products Customer tags Minimum quantities Discount values Campaign dates Market or country conditions The app converts those settings into configuration data that its Function can use when Shopify processes a cart. Are Shopify Functions available on all Shopify plans? Yes, it is. Public Shopify Functions apps can be used by stores on any Shopify plan, except where Shopify places a restriction on a particular API, operation, checkout feature, or app. However, merchants should still review: The app developer’s supported plans Restrictions for the specific Function operation Checkout and sales-channel compatibility Whether the app requires Shopify Plus features Limits involving subscriptions, POS, draft orders, or accelerated checkout Are Shopify functions available only on Shopify Plus? No. Shopify Functions are not available only on Shopify Plus. Stores on any plan can use approved public apps from the Shopify App Store that contain Functions. However, Plus is required for specific advanced operations. Here’s a breakdown. RequirementPlan availabilityInstall a public Functions app from the Shopify App StoreAny Shopify plan, subject to feature restrictionsBuild and install a custom app containing Shopify FunctionsShopify PlusUse advanced operations marked as Plus-onlyShopify PlusUse restricted network access for some Function targetsShopify Plus or Enterprise, depending on the API How does the latest Functions update help merchants? More customization without managing code Shopify Functions can be delivered and configured through apps. Therefore, most merchants can use advanced rules without seeing or editing the Function code. Better performance during busy sales Shopify says Functions execute in under 5 milliseconds on its WebAssembly platform. This is helpful during the busiest shopping days of the year. Know more details about the busiest shopping days of the year to prepare for 2026. Easier maintenance A Functions app can be updated and distributed by its developer. Merchants do not need to copy updated code into every store. This can make ongoing maintenance easier. More consistent backend rules Theme customizations may behave differently across online storefronts, accelerated checkout buttons, mobile apps, and other sales channels. Functions operate in Shopify’s backend, which can make business rules more reliable across supported surfaces. However, each Function API has its own compatibility table, so merchants must still verify whether it supports POS, subscriptions, draft orders, accelerated checkout, and other relevant channels. Shopify Scripts to Shopify Functions migration guide Step 1: Open the Shopify Scripts customizations report From Shopify admin: Go to Apps Open the Script Editor app (Only available till July 30, 2026) Find the Replace your Shopify Scripts banner Click Replace Shopify Scripts The report lists previously active customizations under areas such as product discounts, shipping, and payment gateways. It may also provide recommended apps and relevant Shopify Functions tutorials. Step 2: Decide which rules still matter Do not recreate every old Script automatically. For each customization, ask: Is the rule still used? Does it still support the current sales strategy? Does Shopify now provide a native feature for it? Can one app replace several Scripts? Did the Script conflict with other discounts or checkout apps? Step 3: Document the original behavior Write down the exact conditions and results for every rule you want to keep. Include: Eligible customers Eligible products Minimum cart values Quantity requirements Discount amounts Shipping conditions Payment conditions Markets and currencies Exclusions Combination rules Error messages Do not select a replacement app based only on a similar feature name. Confirm that it can reproduce the complete business rule. Step 4: Choose a public app or custom development A public app is usually suitable when the requirement involves common use cases such as: Tiered discounts Free gifts Bundles Shipping rules Payment restrictions Quantity limits Custom development may be necessary when the logic depends on proprietary workflows, unusual data, complex B2B rules, or several connected systems. Remember that a custom app containing Shopify Functions requires Shopify Plus. Step 5: Rebuild the rules Configure the replacement using the chosen Shopify Functions app or custom app. Keep the first version as close as possible to the original Script behavior. Avoid adding unrelated changes during migration because that makes problems harder to identify. Step 6: Test every important scenario Test more than one successful checkout. Cover: Eligible and ineligible customers Minimum and maximum cart values Discount combinations Different countries and currencies Mobile and desktop checkout Shop Pay and other accelerated checkouts Subscriptions Draft orders Local delivery and pickup Shopify documents different compatibility levels for each Function API. A rule that works during standard online checkout may behave differently with subscriptions, draft orders, order editing, or POS. Step 7: Monitor live orders After launch, monitor: Discount amounts Shipping charges Payment availability Checkout errors Bundle inventory Order routing Customer support tickets App execution errors Pricing and checkout logic should be treated as revenue-critical functionality. Review it after app updates, Shopify API changes, theme changes, and major campaign launches. Important Shopify Functions limitations Functions have resource limits Shopify sets limits on compiled size, memory, input size, output size, and execution instructions. Functions must be efficient because they run during key purchase steps. This means extremely complex rules may need to be simplified or split into a better data structure. App conflicts are still possible Several discount Functions can run at the same time, but they do not communicate directly with each other. Shopify evaluates its results using the discount combination settings attached to each discount. Check the combinations between discount, bundle, gift, subscription, shipping, and checkout apps before launching a major campaign. Do you need a developer to use Shopify Functions? You do not need a developer when a public Shopify Functions app already supports your use case. A developer becomes useful when: No existing app matches the rule The logic depends on custom data Several systems need to work together Your store has complex B2B requirements You are replacing heavily customized Shopify Scripts The rule affects several checkout stages You need a custom Functions app on Shopify Plus Final thoughts Shopify Functions have moved advanced commerce logic away from the old Script Editor and into a faster, app-based system. Merchants can create more relevant discounts, flexible bundles, safer checkout rules, clearer delivery options, and better payment experiences without coding. Shopify Functions are also available across Shopify plans, while custom Functions apps and some advanced capabilities remain restricted to Plus or Enterprise. Start with the business rule you need, confirm the app and plan compatibility, and test the complete customer journey before publishing it. FAQs 1. What are Shopify Functions? Shopify Functions are backend rules that customize how Shopify handles discounts, carts, delivery, payments, validation, fulfillment, and other parts of checkout. They are delivered through apps and run on Shopify’s infrastructure when customers shop. 2. What is a Shopify Functions app? A Shopify Functions app is a public or custom Shopify app that contains one or more Functions. It gives merchants an interface for configuring the Function’s rules without editing its underlying code. 3. Are Shopify Functions available on all Shopify plans? Public apps containing Shopify Functions can be installed on any Shopify plan unless the app or specific Function capability has additional restrictions. Merchants should check the app listing and Shopify API documentation for plan and checkout compatibility. 4. Are Shopify Functions available only on Shopify Plus? No. Public Shopify Functions apps can work on Basic, Grow, Advanced, and Plus plans. Shopify Plus is required for custom apps containing Shopify Functions and for some advanced operations. 5. What replaced Shopify Scripts? Shopify Functions replaced Shopify Scripts for custom discount, shipping, payment, cart, and checkout logic. Shopify Scripts stopped executing completely on June 30, 2026. 6. What is the difference between Shopify Functions and Shopify Scripts? Shopify Scripts used Ruby code in the Script Editor and were available only to Shopify Plus merchants. Shopify Functions run through apps on Shopify’s backend, and public Functions apps can be used across Shopify plans.
