Shopify Scripts End June 30: Check Your Checkout This Week

· 8 min read

If you're knee-deep in orders and this is the first you're hearing of it, no judgment. The Shopify Scripts deadline got buried under a lot of bigger announcements this year, and Shopify's notification was... understated. But the date is real: on June 30, 2026, Shopify Scripts stop executing. No extensions. No opt-outs. If your checkout runs any Scripts right now, it will silently stop doing that thing in 62 days.

The good news: checking whether you're affected takes about five minutes, and fixing it is manageable if you start now. The bad news: April 15 already passed, meaning you can no longer edit or publish Scripts — you can only replace them.

Here's what you need to know.

Wait — Do You Even Use Scripts?​

That's the first question, and a lot of merchants aren't sure. Scripts were originally a Shopify Plus-only feature, but they also got baked into many third-party apps. If you or a developer ever set up custom checkout logic — tiered discounts, BOGO deals, conditional shipping rates, hiding certain payment methods — there's a decent chance Scripts are involved.

Here's how to check in five minutes:

  1. Go to Shopify Admin → Apps → Script Editor (search "Script Editor" if it's not visible)
  2. If you see any Scripts listed — even inactive ones — write down what each one does
  3. Check with your developer or agency if you inherited any Scripts you didn't set up yourself

If your Script Editor is empty, you're clear. Stop reading, go get a coffee — you've earned it.

If you see Scripts running, you've got work to do before June 30. Here's what your options look like.

What Scripts Do (and Why They're Going Away)​

Scripts are small chunks of Ruby code that run inside your checkout to modify the experience in real time. The three types are:

  • Line item Scripts — custom discounts: BOGO, tiered pricing, bundle deals, conditional promotions
  • Shipping Scripts — custom shipping rates: free shipping over a threshold, hiding carriers by country, renaming shipping options
  • Payment Scripts — conditional payment visibility: hiding certain methods for certain order values, customer tags, or countries

They've been a staple of complex Shopify setups for years. The reason they're going: Scripts ran on a legacy Ruby runtime that can't keep up with where the platform is heading. The replacement, Shopify Functions, is built on WebAssembly — it runs faster (sub-5ms), more reliably, and integrates with Shopify's current checkout architecture.

The migration isn't punishment. Functions genuinely do more than Scripts did. But a Script you set up two years ago doesn't automatically become a Function. Someone has to make that switch before June 30.

Your Options (By Store Type)​

If you're on Basic, Grow, or Advanced (non-Plus)​

Good news: you can solve most of this without a developer.

For common use cases, there's either a native Shopify feature that already covers it, or a public app in the App Store built on Functions that handles it without any custom code.

Automatic discounts (BOGO, buy X get Y, percentage off): Shopify's built-in discount engine handles many of these natively. Go to Shopify Admin → Discounts and check before you install anything new — you may not need a Script at all.

Tiered discounts and bundle pricing: Apps like Discount Ninja, Bundler, and Bold Discounts are all built on Functions and available to any Shopify plan. Most run $5–$20/month.

Custom shipping rules: ShipZip and Advanced Shipping Rules handle complex carrier logic without custom code.

Payment method visibility: Payment Rules handles conditional payment display — hide or reorder methods based on cart value, customer tag, or country.

Budget about 1–2 hours to install, configure, and run test orders to verify the logic matches what your Script was doing. Annoying but one-time.

If you're on Shopify Plus​

You have two paths:

  1. Use a public app — same as non-Plus, often faster and cheaper than custom code
  2. Build custom Functions — requires a Shopify Partner developer and a private app setup

If you had a developer build your Scripts, reach out to them now. This is not a same-week job for most agencies if you haven't already started. Custom Function builds typically take 2–4 weeks from scoping to testing. June 30 is 62 days away — that runway exists, but not if you wait another month.

If your Scripts were doing something highly bespoke — multi-currency discount stacks, wholesale-specific shipping logic, B2B payment terms — that conversation needs to happen this week.

The Timeline: What's Still Possible​

Here's where things stand:

DateWhat it means
April 15 (passed)Last day to edit or publish new Scripts. Existing Scripts still run, but you can't change them.
Now through June 29Scripts and Functions can coexist and run in parallel. Use this window to test replacements.
June 30Scripts stop executing. No error message to your customers — your checkout just stops doing the thing the Script was doing.

The parallel window is genuinely useful. Set up your replacement now, run test orders with both active, and confirm the behavior matches. By the time June 30 arrives, you'll already know the replacement works.

Four Things Worth Doing This Week​

1. Open Script Editor and take inventory​

About 5 minutes.

Log in to Shopify Admin and find Script Editor. List every Script you see, active or not. This is your starting point.

2. Write down exactly what each Script does​

About 10–20 minutes.

Before you replace anything, document the logic in plain English. "Applies 15% off to orders over $150." "Hides Cash on Delivery for international orders." "Free shipping when cart contains more than 5 items." You need to know what behavior you're preserving before you can replicate it.

3. Match each Script to a replacement​

About 20–30 minutes of research.

For each Script, pick your path: native Shopify discount feature, App Store app, or custom Function. For most merchants, a quick App Store search for your specific use case (e.g., "tiered discounts," "custom shipping rules") will surface a Functions-native app within a few minutes.

4. Install, test in parallel, confirm​

1–3 hours depending on complexity.

Install the replacement while your Script is still running, then place test orders to verify the behavior matches. Once you're confident, you can stop worrying about June 30.

One More Thing​

The August 26, 2026 deadline for Additional Scripts — the custom JavaScript you may have added in Settings → Checkout for tracking pixels, Google Analytics, or other injections — is a separate migration (to Shopify Pixels) and only applies to non-Plus stores. It's worth knowing about, but it's a different task from Scripts. Handle Scripts first.

And if your store uses any AI chat or widget tools like WebDialogAI, those run separately from your checkout logic — no action needed on that side. But your checkout Scripts are worth a look today.

We know there's always something to track. This one's concrete, fixable, and has just enough runway — but only if you start this week rather than the week before the deadline.

Hang in there. See you tomorrow.
