Shopify Scripts Will Be Deprecated on June 30: What Your Store Must Do?

Shopify Scripts deprecation is not a future event, but the first deadline has already passed. As of April 15, 2026, no merchant can edit, update, or publish new Scripts in the Script Editor. Every Script currently running in production is frozen code. If a bug surfaces, a discount rule misfires, or a shipping condition stops working correctly between now and June 30, there is no path to fix it inside the Script Editor, as the window has closed.

This is the most significant Shopify news for Plus merchants in 2026. For store owners who built their checkout customization on Scripts, the custom discount logic, tiered pricing, wholesale rules, and payment gating all stop working the moment June 30 ends. Not with a warning, not with an error message, but silently, from the moment July 1 begins. The stores that will feel this hardest are the ones where Scripts have been running in the background for years, untouched, invisible, and now impossible to repair.

Check this guide to understand exactly what is changing, what will break if no action is taken, and what your store needs to do before the deadline closes.

What Were Shopify Scripts and What Did They Do for Your Store?

Shopify Scripts were a Shopify Plus-only tool that allowed stores to run custom checkout logic that the standard Shopify platform could not handle. They were powerful precisely because they were flexible, where a merchant could configure almost any condition, and the Script would automatically apply the right rule without the customer or the store team needing to do anything manually.

In practice, most stores use Scripts to apply custom discounts that standard Shopify discount codes cannot replicate, control which shipping options appear based on the customer or the cart, or show and hide payment methods depending on who is buying and where. A wholesale customer tagged as a VIP gets 20% off automatically, free shipping kicks in at a different threshold for B2B buyers than for retail customers, or cash-on-delivery is hidden for international orders. All of that ran through Scripts.

That is precisely why the June 30 deadline is more disruptive than it appears. The stores most at risk are not the ones actively using Shopify Scripts. They are the ones where Scripts have been quietly running for years, and nobody is watching them.

What Happens to Your Shopify Store After June 30 If You Have Not Migrated?

When Shopify Scripts stop executing on June 30, the store does not crash. The checkout still loads, customers can still place orders, and nothing looks broken from the outside. What stops working is everything your Scripts were doing quietly in the background, and it stops without any warning, error message, or notification from Shopify.

• Every custom discount rule built in Scripts reverts to zero.
• A B2B customer who should see wholesale pricing at checkout instead pays full retail.
• A promotion that was supposed to apply a free product for orders above a certain value simply does not apply.
• Shipping rates that were customized to show different options for different customer segments revert to whatever Shopify's default configuration shows.
• Payment methods that were gated by customer tag or geography become visible to everyone or disappear entirely, depending on how the Script was written.

For stores running complex B2B wholesale rules or promotional pricing during a peak sales period, this is not a minor inconvenience but a direct revenue event. The stores that discover it earliest are the ones that have a process in place to catch it. The stores that discover it weeks later are the ones reading bank statements, wondering where the margin went.

What is Shopify Functions and How Does it Replace Shopify Scripts?

Shopify Functions is the official replacement for Scripts and the platform's primary extensibility layer going forward. It handles the same things Scripts did, including custom discounts, shipping rules, and payment logic, but it is built on a completely different and more capable foundation.

The most important thing for a store owner to understand is that Shopify Scripts migration to Functions does not mean rebuilding your checkout from scratch. It means moving your existing customizations into a system that is faster, more reliable, and actively supported by Shopify. Scripts were a legacy tool with no testing environment, no version control, and no path for Shopify to further evolve them. Functions fix all three of those problems through:

• Execution speed (under 5ms): Consistent performance even during Black Friday traffic spikes.
• Availability (all plans): Any store can use Functions via App Store apps. Custom apps require Plus.
• Testing (Dev store): Functions can be fully tested before going live. Scripts offered no equivalent.
• Migration window (parallel): Scripts and Functions can run side by side until June 30, allowing a safe handover.

The Key Reassurance for Store Owners

The migration does not have to happen all at once. Each Script can be replaced with its Function equivalent one at a time, tested alongside the existing Script, and switched over only after it is confirmed to work. The risk is not the migration itself, but it is leaving it too late to do it carefully.

Shopify Scripts to Functions Migration: Your Three Paths Forward

Not every Script requires the same migration path. The right approach depends on what each Script was doing and how complex that logic was. Most stores will end up using a combination of all three paths rather than a single solution for everything.

Shopify Functions

The direct replacement for Scripts. Shopify Functions replicate discount, shipping, and payment customization in a modern, app-based system. For Shopify Plus merchants with complex B2B pricing tiers, conditional discount stacking, or custom payment gating, this is the only path that fully preserves checkout-level logic. Start by running the Shopify Scripts customizations report in your admin to identify which Scripts map to this path.

Shopify Flow

Shopify Flow handles event-driven automation, including customer tagging, internal notifications, discount code triggers, and order management workflows. If any of the Scripts were performing operational tasks rather than inline checkout logic, Flow is the cleaner replacement. It does not run at checkout in real time, which makes it unsuitable for live cart manipulation but well-suited for everything that happens before or after checkout.

App Store Apps

For merchants whose Scripts handled common discount or shipping scenarios, a wide range of Shopify App Store apps built on Functions already cover the same functionality without requiring custom development. This path is the fastest to implement and requires no developer involvement for standard use cases. It is the right starting point for stores with straightforward promotional logic that does not involve custom B2B pricing or complex stacking rules.

The recommended sequence is to run the Shopify Scripts customizations report first, categorize each Script by which path it maps to, prioritize by revenue impact, and work through them one at a time before the June 23 recommended live date.
