Shopify has begun the merchant rollout of market-driven shipping, opening opt-in access on October 1, 2026 and starting a staged shift that is scheduled to reach all shops by July 1, 2027.
Under Shopify’s current system, many stores manage shipping through delivery profiles, location groups, shipping zones, and rates. Shopify’s developer changelog says merchant-owned shipping configuration is moving out of delivery profiles and into Markets.
Shopify’s Help Center describes the public-facing name for the new merchant setup as shipping options by market. From Markets in the Shopify admin, a merchant can set delivery choices such as Standard or Express for a market, then use rate conditions to handle differences by product group or fulfillment location.
For stores selling across Canada, the United States, or other regional markets, the practical read is that market setup becomes a shipping operations issue as much as an international selling issue. A market can represent a group of countries, a sub-region such as a province or state, or B2B customer locations. That means the market structure can influence which shipping options appear at checkout.
The rate change has limits
Under shipping options by market, when a cart matches more than one flat or order amount rate inside the same shipping option, Shopify charges the highest matching rate instead of adding those rates together. This can reduce cases where a mixed cart is charged stacked shipping because products came from different profiles or locations.
The rule is not universal. Shopify’s Help Center says weight-based, carrier-calculated, and app-calculated rates are still calculated for each shipment and added together when an order is split. Rates from different shipping options are also added together.
A store using one Standard flat-rate option with product variations may see different pricing behavior than a store using separate Standard and Express options, carrier-calculated rates, or app-provided rates. Market-driven shipping changes the model, but it does not make every split shipment cheaper.
The rollout is gradual
Shopify’s October 1 peak-season fulfillment post says all merchants are eligible for market-driven shipping and can opt in from Shipping and delivery settings. Shopify’s earlier enterprise and developer materials set July 1, 2027 as the date when the new setup is scheduled to be enabled for all shops.
Not every store changes immediately. Shopify’s Help Center says existing rates keep working until a store is upgraded, and that the shipping setup is migrated during the upgrade so most merchants do not need to recreate rates. Stores that use shipping apps might be upgraded later, after those apps become compatible.
During the transition, two shipping systems can exist across Shopify stores. Merchants can tell which system a store uses from Settings > Shipping and delivery: stores still organized around shipping profiles remain on the current system, while upgraded stores show shipping options organized by market.
Shopify also says stores can switch back to shipping profiles during an opt-out window after the upgrade, if that window is available. The rollback is not neutral. Shopify warns that switching back restores the previous shipping setup and removes shipping changes made after the upgrade, along with collections or sub-region markets created during migration.
Apps are the main breakage risk
Shopify’s developer documentation says merchant-owned shipping configuration is moving to the Markets API, while app-owned delivery profiles continue to use the existing DeliveryProfile API.
Apps that only create and manage their own app-owned delivery profiles may not need changes. Apps that read, create, or modify a merchant’s delivery profiles need to update their read or write paths. Shopify also advises developers to audit GraphQL operations for delivery profile usage if the app’s role is unclear.
Starting October 1, 2026, Shopify says new installs can see a compatibility warning if an app is not marked compatible. Shopify’s upgrade guide says existing merchants using an app are not automatically moved until Shopify confirms the app is compatible, but manual opt-in can still cause breakage if the app has not been upgraded.
Custom apps are part of the same issue. Shopify’s enterprise guidance says custom or third-party apps that read, create, or modify merchant delivery profiles need to be updated. Its partner guidance also flags fulfillment, 3PL, order management, and ERP integrations that touch delivery, fulfillment, or order logic.
What merchants should watch now
Market definitions: Markets now carry more shipping responsibility, especially for stores selling across countries, provinces, states, or B2B customer segments.
Staff permissions: Shopify says staff who manage shipping need the Markets permission after upgrade, and that permission is not automatically included in existing staff roles.
Rate names and rate types: Similar option names can be consolidated during migration, while flat and order amount rates behave differently from weight-based, carrier-calculated, and app-calculated rates.
Shipping apps: Stores that depend on third-party or custom app rates should verify compatibility before opting in, especially if an app controls checkout rates or external fulfillment logic.
Checkout testing: Mixed carts, multiple fulfillment locations, regional markets, preorder items, and carrier or app rates deserve testing after migration.
Shopify is positioning the change as a way to make shipping setup clearer and checkout pricing more predictable. The useful test for merchants is narrower: whether the store’s actual markets, rates, apps, and fulfillment locations still produce the checkout experience customers expect.
