Will my Shopify shipping app still work after the move to Markets?

Short answer: it depends what the app does. Shopify's move from shipping profiles and zones to shipping options by market hits different apps in different ways. Some don't need to change at all. Some need an update before your store moves over.

I build a shipping app, so I've spent more time in Shopify's developer docs on this than I'd like to admit. Here's the plain-English version, with Shopify's sources, so you can work out where your apps sit.

(New to the change itself? Start with Shopify shipping is moving to Markets: what's changing and when.)

The four kinds of shipping app

Most apps that touch shipping fall into one or more of these groups.

1. Apps that show live rates at checkout (carrier- or app-calculated)

These apps give Shopify a live quote when your customer reaches checkout. Shopify calls this a "carrier- or app-calculated" rate.

What Shopify says: "Carrier or app calculated" is one of the rate types you can add to a market in the new system, alongside flat, order-amount and weight-based rates. (Shopify Help Center: setting up shipping options) On the developer side, the new Markets shipping API includes a carrier-calculated option type that points at the app's existing carrier service. (Shopify changelog, 1 Jul 2026)

What that means: live checkout rates have a proper home in the new model. The rate gets attached to a market, and you can set it up for each market you sell to.

2. Apps that manage their own rates

Some apps create their own shipping profile and keep their rates in it. Shopify calls these app-owned delivery profiles.

What Shopify says: if an app only creates and manages its own profile and doesn't read yours, "No changes required." These app-provided rates appear in your market's shipping options. You can switch them on or off, but you can't edit the details, because the app manages them. (Shopify dev docs: upgrade guide, Shopify Help Center)

3. Apps that read or edit your shipping profiles and zones

These are apps that set up zones and rates for you, sync your shipping settings to another system, or read your profiles to show shipping info somewhere else.

What Shopify says: these apps must update. For stores on the new system, Shopify says the old profile APIs "may return a stale snapshot" when read, and writes "may succeed without errors but will not update the merchant's live shipping settings." (Shopify changelog, 1 Jul 2026)

In plain English: an app that hasn't been updated could think it changed your rates when it didn't. That's the one to watch.

4. Apps that don't touch shipping settings at all

Label, booking and tracking apps that only work on orders after they're placed generally aren't affected by this change. They might still show old menu paths in their help docs, though.

How to check whether your app is compatible

Look for Shopify's banner. On Settings > Shipping and delivery, Shopify shows a banner if an installed app isn't compatible with shipping options by market. (Shopify Help Center)
Check with the app developer. Shopify gives developers a compatibility self-attestation form, and apps that pass are marked compatible. Shopify says it will also try to detect compatibility automatically. (Shopify dev docs)
Don't rush to opt in. Shopify says it won't automatically move stores onto the new system until their apps are confirmed compatible. The Help Center puts it as: stores that rely on shipping apps are upgraded later, after those apps become compatible. The risk is opting in yourself before an app is ready. Shopify warns an incompatible app's rates might not show at checkout, which can stop customers completing an order.

Questions worth asking your app developer

Does your app read or change my shipping profiles or zones?
Are you marked compatible with shipping options by market yet? If not, when do you expect to be?
After my store is upgraded, do I need to switch your rates on in Markets, or add them myself?
Do your help docs and error messages still point to Settings > Shipping and delivery?

Any decent developer should be able to answer those in a couple of lines.

Turning app rates on under Markets

Once your store is upgraded, your shipping lives in Markets, so that's where you check your app rates.

To check rates an app provides: go to Markets, open your market (for example Australia), and click Shipping. App-provided rates are listed alongside your own shipping options, and you can activate or deactivate them. (Shopify Help Center)

To add a live-rate app as a shipping option (from Shopify's steps):

From your Shopify admin, go to Markets.
Click the market you want to set up shipping for.
Click Shipping, then Add shipping option.
Enter a name for the option.
From Rate type, select Carrier or app calculated.
Select the carrier or app, then the services you want customers to see.
Optional: add a handling fee (percentage, fixed amount or both). A negative value gives a discount.
Optional: limit the rate to specific collections or "Ships from" locations.
Click Done, then Save.

Why newly installed live-rate apps might not show up on their own

This is a separate Shopify change that runs alongside the Markets move, and it's easy to miss.

Historically, when you installed an app that provides live rates, Shopify automatically added it to your General shipping profile, so rates just appeared at checkout. From API version 2026-10, Shopify no longer does that. Creating a carrier service "only registers the carrier service", and Shopify's recommended approach is for apps to direct merchants to add the carrier-calculated rate themselves. Older API versions keep the automatic behaviour until they're retired. (Shopify changelog, 26 Jun 2026)

What that means for you: when you install a new live-rate app, expect that you may need to switch its rates on yourself. On an upgraded store, that's in Markets using the steps above. On a store that hasn't been upgraded yet, it's in your shipping profile. If you've installed an app and no rates show at checkout, check this before anything else.

Other things that can hide app rates

Shipping turned off for a market. Merchants can turn shipping on or off for each market. Shopify's developer notes say turning it off also switches off app-managed shipping options for that market. (Shopify changelog)
A market with no shipping set up. A child market inherits from its parent. Shopify's developer notes say a market with no parent and no shipping config defaults to no shipping. (same source)
Third-party carrier-calculated shipping not active. Shopify's troubleshooting guide says that if an app uses carrier-calculated shipping, you should check that third-party carrier-calculated shipping is available and activated for your store. Shopify lists plan requirements for it. (Troubleshooting, Third-party carrier-calculated shipping)
Missing weights and dimensions. Calculated rates depend on accurate product weights and package sizes. That was true before and it's still true.

Help docs and error messages will lag

For years, every shipping app (ours included) has told merchants to "go to Settings > Shipping and delivery" to fix a rate problem. For upgraded stores, rates now live in Markets > [market] > Shipping. Some in-app messages and help articles across the ecosystem will be out of date for a while, and even some of Shopify's own articles still describe the profile-based steps for stores that haven't moved yet.

If the steps you're following don't match your screen, check which system your store is on (Settings > Shipping and delivery tells you) and look in Markets.

Where Pack sits

Being upfront, since I build one of these apps.

Pack to the Future supplies live rates at checkout (group 1 above). Because Pack provides live carrier-calculated rates, it keeps working when a store moves to Markets — that's the rate type Shopify has built into the new model. We'll be testing Pack on Shopify's new Markets shipping before stores migrate, so we can give merchants clear steps on how our rates show up inside a market. We're also working through our own help docs and in-app messages that still say "Settings > Shipping and delivery".

The other reason I'm across this: managing shipping settings from within Markets — not just supplying rates — is on our roadmap. When we build it, it'll be for the Markets model rather than for a system that's being retired.

FAQ

Will carrier-calculated shipping still work on Shopify after the move to Markets? Yes. "Carrier or app calculated" is one of the rate types you can add to a market. You may need to check the rate is switched on in each market you sell to.

Which shipping apps need to update? Apps that read, create or change your own shipping profiles and zones. Apps that only manage their own rates don't need changes, according to Shopify's developer guide.

How do I know if an app is compatible? Look for Shopify's banner on Settings > Shipping and delivery, check the app's help docs or changelog, or ask the developer whether they're marked compatible with shipping options by market.

Will Shopify move my store if one of my apps isn't compatible? Shopify says stores that rely on shipping apps might be upgraded later, after those apps become compatible. You can still opt in yourself, but an incompatible app's rates might not show at checkout.

I installed a live-rate app and no rates show at checkout. Why? From API version 2026-10, Shopify no longer adds new live-rate apps to your shipping automatically. Add the app as a "Carrier or app calculated" shipping option in Markets (or in your shipping profile if you haven't been upgraded), and check third-party carrier-calculated shipping is active on your store.

Can I edit an app's rates in Markets? Not rates the app provides. You can switch them on or off, but the app manages the details. A carrier- or app-calculated option that you set up yourself can take a handling fee and product or location conditions.
