Shopify Scripts Deprecation: What to Do Now That They've Stopped Working

If a discount code stopped applying, a shipping rule stopped triggering, or a BOGO promotion quietly vanished from your checkout sometime in the last few weeks, you're not imagining it. Shopify Scripts, the tool a lot of stores used to run custom discount and checkout logic, stopped working for good on June 30, 2026. It didn't throw an error. It just stopped.

If you never touched Scripts yourself, someone who built your store years ago probably did, and you likely have no idea it's even in there.

What actually happened

Shopify froze editing and publishing of Scripts back on April 15, 2026, then shut them off completely on June 30. Shopify Functions, a newer and more capable system built on WebAssembly, is the official replacement. The problem for most small store owners isn't the technology change itself, it's that nobody told them their store depended on Scripts in the first place.

Scripts were commonly used for things like:

• Tiered discounts ("spend $150, get 20% off")
• Buy-one-get-one and bundle-based promotions
• Customer-tag-based pricing (wholesale, VIP, staff discounts)
• Free or discounted shipping based on cart contents
• Payment method restrictions or surcharges

If any of these were built with a Script rather than Shopify's native discount tools, they stopped working the moment the deadline hit, and your checkout has been running without that logic since.

How to tell if you were affected

Go to your Shopify admin, open Apps, then Script Editor. There's a Scripts customizations report that lists every active Script your store was running and what it did. If that report shows anything, treat it as a live incident, not a future to-do. Every day it sits unresolved is a day customers may be seeing wrong prices or missing promotions.

If you don't have direct access to Script Editor or aren't sure what you're looking at, a quicker gut check: pull up a few of your store's known promotions (a bundle deal, a VIP discount, a shipping threshold) and manually test them in an incognito browser tab. If a discount that used to apply doesn't anymore, that's your answer.

What to do about it now

If the logic was simple. Something like "10% off orders over $100" or a straightforward free-shipping threshold doesn't need Scripts or Functions at all. Shopify's native discount tools in Settings > Discounts already handle this. Rebuild it there and you're done in a few minutes.

If the logic was more complex. Tiered pricing, stacked discounts, customer-tag-based rules, or conditional BOGO offers need a Shopify Functions-powered app. Several apps in the Shopify App Store now cover the most common Script use cases without you writing any code, so this is usually a matter of picking one that matches what you lost, not rebuilding from scratch.

If it was genuinely custom. Some stores had bespoke logic that doesn't map cleanly to an off-the-shelf app. That needs a developer to rebuild it as a custom Function, but scope it narrowly. You're replacing one specific rule, not redoing your whole checkout.

Whichever path applies, treat this the same way you'd treat checkout friction you're actively losing money to: test the new setup with real test orders before you trust it, because a discount that applies incorrectly is arguably worse than one that's simply missing, since now you're either losing margin or annoying customers who expected a promo that isn't there.

Give yourself a real testing window, not a five-minute spot check. Place a handful of test orders that trigger each rule you're rebuilding: the tiered discount, the VIP price, the bundle offer, the shipping threshold. Confirm the price at checkout matches what you expect before you consider the migration done. It's tempting to rebuild a rule, glance at it once, and move on, but checkout logic is exactly the kind of thing that looks right in a quick test and then misbehaves on a specific combination of products or discount codes you didn't think to try.

A worked example

Say your store ran a Script that gave repeat customers (tagged "VIP") automatic 15% off, and roughly 8% of your monthly orders came from that segment. If those customers stopped seeing their discount on June 30 and nobody caught it, you've spent three weeks either quietly overcharging your best customers or, just as likely, they noticed the code wasn't working, got annoyed, and some abandoned their cart. Either outcome costs you more in trust and lost repeat purchases than the two hours it takes to rebuild that rule properly.

Multiply that across a full quarter of missed VIP discounts, a broken shipping threshold, and a bundle offer that silently stopped applying, and you're looking at a meaningful dent in repeat purchase rate, not just a few annoyed one-off customers. The damage compounds precisely because nothing about it throws an error or shows up in a report. It only shows up as a slightly worse month that's hard to trace back to a single cause.

Why this keeps happening to small stores

This is the same pattern behind a lot of invisible revenue leaks small store owners deal with: a system quietly breaks or underperforms, nobody's specifically watching that corner of the store, and it takes a customer complaint or a lucky manual check to even notice. It's the same reason stores miss stockouts costing them sales, and it's a good reminder to periodically check what's actually running in your Shopify app stack instead of assuming everything you set up months or years ago is still doing its job.

You don't need to babysit every corner of your Shopify admin for these platform changes. You need something that flags this kind of thing automatically, whether it's a deprecated feature, a broken discount, or a checkout rule that stopped firing, before it costs you weeks of quiet losses.
