Platform Updates Hitting Your eCommerce Store (And How to Get Ahead of Them)

While you're heads down on inventory, campaigns, and customer service, your eCommerce platform is probably making background changes that affect your checkout and shipping setup. A feature gets deprecated. An API rule shifts how your integrations behave. A pricing update adds a fee you didn't see coming. None of it waits for you to have a free afternoon.

Platforms (like Shopify, BigCommerce, Magento, and Adobe Commerce, to name a few) are constantly building new features, redesigning layouts, and updating their tech, all aimed at one thing: helping you sell more product, faster.

That's a good thing…mostly.

The catch is the pace. Updates roll out fast, sometimes overnight, and merchants don't always get a heads-up when a platform is A/B testing a new feature or checkout flow. That means your checkout and shipping setup needs a strong enough foundation to hold up no matter what gets thrown at it.

If you can't keep up, we can. If a platform update has you confused, or you suspect something shifted without you realizing it, the ShipperHQ team is happy to help you sort it out.

Here's a rundown of the most recent eCommerce platform changes that we think are worth your attention right now, and what to do about each one.

Shopify’s Fall ‘26 Edition Brings Checkout Into AI Chats

Effective: October 28, 2026

Shopify released its Fall ‘26 Edition, called “Exponential,” with more than 150 updates, about six weeks earlier than its usual December release and a month before Black Friday. Most of the changes are minor — just general housekeeping — but a handful of changes affect how your shipping and delivery information reaches shoppers, especially shoppers who never visit your storefront.

The headline: AI agents can now complete checkout, not just browse. Shoppers can find a product, approve the purchase, and pay with Shop Pay inside AI assistants like Claude, Grok, and Meta’s Muse, and buy directly in Google’s AI Mode and the Gemini app. Those orders land in your Shopify admin like any other, shipping details included.

A few updates you should know:

• Shipping settings move into Shopify Markets. This one rolled out October 1, just ahead of the Edition: Shopify is moving shipping rate setup out of Shipping Profiles and into Markets. New stores are on it now, and existing stores must migrate by July 1, 2027.
• Split shipping is becoming mandatory. As part of the move to Markets, split shipping will be mandatory for all merchants July 1, 2017. Customers will see the number of shipments displayed at checkout. For carrier-calculated rates, the cost of each shipment will be added together. For flat rates and order amount rates, only the highest matching rate within a shipping option is charged.
• Agentic checkout. Shop Pay checkout now runs inside third-party AI agents and Google’s AI surfaces.
• A knowledge base for agents. You can now review and approve the business details AI agents share about your store, including shipping and return policies. Nothing reaches an agent until you publish it.
• Shop Promise ranks higher. Products with the Shop Promise badge, which signals reliable delivery and returns, now rank higher in Shop app search and Shopify Catalog. Only 1% of Shopify merchants are eligible for Shop Promise.
• Checkout custom fields. Shoppers can add gift messages or delivery instructions at checkout.
• All-in international pricing. Shopify Managed Markets can now show prices with duties and taxes included, alongside flat-rate shipping.
• Bigger Rollouts. One scheduled rollout can now bundle theme, checkout, catalog, and discount changes, and roll back automatically when a promotion ends.

Who it hits: Every Shopify merchant, but especially stores with complex shipping (multiple carriers, delivery dates, restricted items, LTL freight) where a vague or wrong answer from an AI agent costs a sale. International sellers and anyone planning a BFCM launch should pay close attention, too.

Your move: Not eligible for Shop Promise? Delivery Date & Time gives shoppers real delivery dates, while giving you more control with custom cut-off times, product-specific lead times, and blackout days. The Product Page Shipping Calculator displays accurate shipping costs and delivery dates on the product page, where 55% of AI-referred sessions land.

Big Changes Coming for Shopify's Carrier Service API

Coming: October, 1 2026

Starting with Admin API version 2026-10, creating a carrier service in Shopify no longer automatically adds rates to the general shipping profile. That used to happen by default. Now it requires explicit configuration after the carrier service is created, or new rates simply won't show up at checkout.

What was updated: New carrier services created via the Admin API need manual configuration to appear in the General shipping profile.
Who it hits: Developers, app partners, and any merchant using an app that provides calculated shipping rates through the carrier service API.
Your move: If you're managing your carriers directly through Shopify's native tools, you'll need to reconfigure them yourself to prevent rates from disappearing at checkout. If you're on ShipperHQ, this is already handled. Our integration automatically stays current with Shopify's Admin API versions.

Shopify Scripts Is Shutting Off for Good

Effective: June 30, 2026

Shopify Scripts stopped running on June 30, 2026. If your store still uses Scripts to apply discounts, control which shipping methods show at checkout, or run any other checkout logic, that logic no longer works.

What was updated: Shopify Scripts is deprecated and replaced by Shopify Functions.
Who it hits: Any Shopify merchant using Scripts for discount logic, shipping method visibility, or custom checkout rules.
Your move: If shipping method visibility or custom shipping rules were part of what your Scripts handled, ShipperHQ's Shipping Rules can move that logic into a system built to keep working through platform changes like this one.

Shopify Checkout Got a Conversion-Focused Redesign

Effective: June 17, 2026

Shopify's Spring '26 Edition shipped a checkout redesign built around conversion: easier-to-scan delivery options, a more prominent pay button, and less scrolling on mobile. Shopify also rolled out managed payment methods, which reorder payment options in real time based on what's most likely to convert for that specific shopper.

What was updated: Checkout redesign for shipping and delivery clarity and mobile usability, plus managed payment methods that dynamically reorder payment options.
Who it hits: Every Shopify merchant, though the impact is most visible for stores with multiple shipping methods or delivery options competing for attention at checkout.
Your move: This is a good moment to revisit how your shipping options actually display. You can control how your shipping options are presented in the cart with Enhanced Checkout, so you and your customers can create a more personalized shipping experience.

BigCommerce Added a New Fee for Non-Approved Payment Providers

Effective: June 1, 2026

BigCommerce introduced an Open Payment Provider Fee, a charge of up to 2% on GMV processed through any payment gateway not on its approved Embedded Payment Provider list. This came alongside a full plan rename and lower GMV thresholds that trigger an automatic plan upgrade.

What was updated: A new fee applies to orders processed through non-approved payment gateways, layered on top of renamed plans and tighter GMV thresholds.
Who it hits: Any BigCommerce merchant using a third-party payment gateway not on the approved list, particularly stores that chose BigCommerce specifically because it didn't tax outside gateways the way other platforms do.
Your move: Check which payment providers are processing your orders today, and how much of your GMV runs through gateways outside BigCommerce's approved list. This is also a good moment to have a broader checkout conversation. If a pricing change is already prompting a review, it's worth the effort to examine how shipping and checkout interact.

Magento and Adobe Commerce Made Checkout Pay Better

Effective: May 12, 2026

Magento 2.4.9 hit general availability in May, bringing real improvements to how customers pay, not just under-the-hood fixes. Apple Pay now works on Chrome and Firefox, not just Safari. Google Pay and Apple Pay Express Checkout both support promo codes for the first time. Saved cards auto-update when they expire or get reissued, cutting down on failed renewals for repeat customers. New local payment methods also landed for Germany and Brazil.

What was updated: Expanded payment method support and express checkout improvements across Magento Open Source and Adobe Commerce.
Who it hits: Any Magento or Adobe Commerce merchant using Braintree, Apple Pay, or Google Pay, especially those selling internationally.
Your move: More payment options at checkout is a genuine conversion lever, but only if shipping keeps pace. A customer who can now pay with Apple Pay on Firefox still bounces if your shipping options are confusing or inaccurate, so tools like Enhanced Checkout or Product Page Calculator work to help payment and shipping improvements move together instead of one outpacing the other.
