Shopify Scripts Are Dead: What to Do If You Don't Have a Developer

Shopify Scripts stopped executing on 30 June 2026. If your automatic discounts, shipping rules or payment logic quietly vanished at checkout around then, that is why. Nothing broke loudly. Carts still worked. Orders still came in. The custom logic just stopped applying, and for a lot of stores the first sign was a margin that looked wrong or a customer asking where their free shipping went.

Most of the advice written about the Shopify Scripts deprecation was aimed at Plus merchants with a developer on staff and a migration plan drawn up months in advance. This piece is for everyone else: you missed the deadline, or you inherited a store where someone else set the Scripts up, and you do not have a developer to call. Here is what has actually changed, how to work out what you lost, and how to get it back without over-spending.

What happened, and why it took so long

Scripts were small Ruby programmes that ran inside checkout. They were a Shopify Plus feature, and for years they were the only way to do things like tiered volume pricing, hiding a payment method for certain customers, or reordering shipping rates. Shopify announced their replacement, Shopify Functions, and set a retirement date of August 2024. That slipped to 28 August 2025, and in April 2025 it slipped again to 30 June 2026. Editing and publishing Scripts was frozen from 15 April 2026, and on 30 June they stopped running for good.

Two extensions in a row trained a lot of merchants to assume there would be a third. There was not. If you are now reading this after the fact, you are in good company, and the good news is that the replacement options are more mature than they were a year ago.

One point of confusion worth clearing up: this is separate from the retirement of additional scripts on the order status page, which affects non-Plus stores from 26 August 2026. That is tracking and pixel code. Shopify Scripts were checkout pricing and rules logic. If both apply to you, you have two jobs, not one. Our earlier piece on what to audit now the checkout extensibility deadline has passed covers the tracking side.

Step one: find out what your Shopify Scripts were doing

The Script Editor app is gone, but Shopify kept a record. In your admin there is a Scripts customisations report, a page that lists each Script customisation that was active on your store before 30 June 2026, along with the replacement Shopify recommends for it. Shopify's own guide to transitioning from Scripts to Functions explains where to find it. Open that report before you do anything else. It is the closest thing you have to a spec.

Then cross-check it against reality, because the report tells you what was configured, not what was commercially important. Pull three months of orders from before the cut-off and look for discounts applied, shipping rates charged, and payment methods used. Compare them with the same data since July. The gaps are your real list. Typical Scripts fell into three families:

Line item Scripts: volume pricing, buy X get Y, customer-tag pricing for trade or VIP customers, bundle discounts, excluding sale items from promo codes.Shipping Scripts: hiding or renaming rates, free shipping over a threshold for some customers only, blocking certain carriers for certain postcodes.Payment Scripts: hiding or reordering payment methods, for example removing a pay-later option for wholesale accounts or high-value baskets.

Rank them by revenue impact. A trade pricing Script that stopped applying is an emergency. A Script that reordered your payment gateways is a tidy-up.

Why non-Plus stores cannot just rebuild them

Shopify Functions is the replacement. Functions run inside Shopify's infrastructure at fixed points in checkout, and they are packaged as apps. There are two kinds of app, and the distinction matters a great deal if you are not on Plus.

Public apps from the Shopify App Store that are built on Functions work on any plan, including Basic. Custom apps, meaning a Function built for your store alone and installed privately, require Shopify Plus. So if you have come off Plus, or you are weighing up whether to stay on it, a bespoke rebuild of your old Scripts is not on the table. Your route is a public app, or a change of plan.

That is less restrictive than it sounds. The Function APIs cover the same three jobs Scripts did (discounts, delivery customisation and payment customisation), and a crowded market of public apps has grown up around them. For the majority of Script use cases, a well-chosen app will do the job. For some, it will not, and we cover that below.

Choosing a public app without getting burned

The temptation is to install the first discount app with good reviews and move on. Resist it. Apps are not free, they add weight to your store, and the wrong one locks you into a pricing model that scales with your order volume. We have written before about how too many Shopify apps slow a store down, and this is exactly how it starts.

Write the rule in plain English first. "Trade customers get 15% off everything except clearance, and free UK shipping over £250." If you cannot state it in a sentence, you cannot evaluate an app against it.Check it is built on Functions, not a workaround. Some older apps fake discounts with draft orders or cart attributes. Those are fragile and will not survive the next checkout change. Look for "Shopify Functions" in the listing or ask support directly.Test the combinations. Stacking rules is where apps fall over. Can a tag-based discount and a volume discount apply together? Does the shipping rule respect the discounted subtotal or the original one? Run real test orders.Look at the pricing tier you will actually be on. Many apps are cheap at 500 orders a month and expensive at 5,000.Prefer one app that does two jobs over two apps that do one. Fewer vendors, fewer conflicts, fewer things to break at peak.

Give yourself a week on a duplicate theme and a test customer account. It is slower than you want, but it is far cheaper than discovering in November that your Black Friday rules do not stack.

When a one-off custom build is the better answer

If you are on Plus, you have a third option: commission a custom Function app. A single, well-scoped Function is a small piece of work for an experienced Shopify developer. It has no monthly fee, no vendor roadmap to worry about, and it does exactly what your Script did, often better, because Functions run in milliseconds with none of the latency Scripts introduced at checkout.

The honest trade-off is ownership. A custom app needs someone to maintain it when Shopify updates the API, which happens on a regular cadence. If you have no developer relationship at all, a public app with a support desk is a safer bet than a custom build you cannot touch. If you have a long-term partner, custom usually wins on cost within the first year. Our piece on when to build a custom Shopify app and when to buy goes deeper on that decision, and our Shopify app development service is where we do this work for clients.

A rough rule we use with clients: if the logic is standard (tiered pricing, threshold shipping, hide a gateway), buy. If the logic is specific to how your business makes money (margin-aware discounting, trade terms that vary by account, regional carrier rules), build. The cases where a merchant genuinely needs custom are rarer than agencies like to suggest, but when they exist, no app will quite fit.

The report tells you what was configured. Your order data tells you what mattered. Fix the second list, not the first.

Do not let the fix become a rebuild

There is a version of this project that turns into a full checkout overhaul, a new discount strategy, and a theme refresh. Avoid it for now. Replace the logic you lost, confirm it works with real orders, and then stop. The urgent job is restoring margin and the customer experience you had on 29 June.

Once that is done, the better question is the one most Shopify brands should be asking anyway: not how to get more traffic, but why the traffic you already have converts the way it does. Most stores we audit in Glasgow and across the UK do not have a traffic problem. They have a conversion problem, and checkout logic is one small piece of it. Our Conversion Growth Retainer exists for exactly that stage: a store with product-market fit, steady traffic, and a plateau that neither a new app nor a new ad budget will break.

If your Scripts stopped working and you want a second opinion on the replacement before you commit to an app or a build, get in touch. We will tell you plainly whether you need us or whether an app from the store will do.
