Shopify Scripts Is Being Deprecated: Here's What Replaces It in 2026
Shopify Scripts retires June 30, 2026 — and its native replacements have no margin protection layer. Here's what Shopify Plus merchants need to do before the deadline.
Shopify announced it years ago, but the deadline is now real: Shopify Scripts retires on June 30, 2026. If your store runs any Ruby-based checkout scripts — for discounts, shipping logic, or payment filtering — those scripts stop executing that day. No warning, no grace period. They just stop.
For many Shopify Plus merchants, this is a bigger deal than it sounds. Scripts have been the quiet engine behind some of the most critical margin-protection logic in their checkout flows for years.
What Shopify Scripts Was
Shopify Scripts was a Shopify Plus–exclusive feature that let merchants write Ruby code to customise the checkout in ways the standard platform didn't support. It ran three types of scripts:
- Line item scripts — modify prices, apply discounts, bundle logic
- Shipping scripts — rename, hide, or reorder shipping options
- Payment scripts — show or hide payment methods based on cart conditions
Because it ran server-side at checkout, merchants could enforce rules that were difficult to replicate in the storefront. A script could inspect every line item, check totals, apply tiered discount caps, or block stacking — all before the order was placed.
How Merchants Used Scripts for Margin Protection
Shopify Scripts became the unofficial home of margin guardrails for Plus stores. Common patterns included:
Coupon stacking prevention. Scripts could detect when multiple discount codes were active simultaneously and reject the combination before the transaction completed. Without this, a determined customer (or a coupon aggregator site) could layer a 20% loyalty code on top of a 15% sale and wipe out your margin in a single order.
Minimum order value enforcement. Merchants used scripts to block free shipping or specific discounts from activating unless the cart met a minimum profitable threshold.
MAP price protection. Brands selling through DTC channels used scripts to ensure that no discount logic — regardless of source — pushed the final price below their Minimum Advertised Price commitments.
These weren't edge cases. For mid-market ecommerce brands doing $5M–$50M in annual GMV, these guardrails could be the difference between a profitable month and a margin-destroying one.
The Official Replacements: Checkout Extensibility and Shopify Functions
Shopify's migration path is Checkout Extensibility and Shopify Functions. These are genuinely better technologies — more performant, more stable, and properly supported.
Checkout Extensibility lets you build UI components that appear natively inside the checkout using React-based checkout UI extensions. It handles visual customisation: custom fields, banners, upsells, loyalty points widgets.
Shopify Functions lets you write backend logic (in Rust or AssemblyScript, compiled to Wasm) that runs directly in Shopify's infrastructure. Functions can handle discount logic, shipping rules, and payment method filtering — everything Scripts could do.
So what's the problem?
Neither of these has a native margin protection layer.
Shopify Functions gives you the building blocks. But building a real-time profitability check — one that accounts for COGS, landed costs, live promotions, and channel-specific margin floors — requires logic that Shopify doesn't provide out of the box. You need to build it yourself, or integrate a tool that does it.
Most merchants are discovering this gap right now, with the June 30 deadline approaching.
What You Need Instead: Real-Time Profitability at Checkout
The requirement is straightforward: before an order is confirmed, something needs to evaluate whether the final transaction is actually profitable given your current cost structure, and block or adjust it if it isn't.
That's exactly what Agentis was built to do.
Agentis is a real-time profit protection layer for Shopify Plus merchants. It integrates with your checkout via Shopify Functions and runs a profitability check on every order — factoring in COGS, promotions, discounts, and your configured margin floors — before the transaction completes.
The 3 Guardrails Agentis Replaces
If you were using Shopify Scripts for margin protection, here's how Agentis maps to what you had:
1. Coupon Stacking Prevention
Agentis monitors discount combinations in real time. When a combination of active discounts would push the order below your margin floor, Agentis blocks the combination or surfaces an alternative (e.g., prompting the customer to choose one code). This is configurable per promotion type and customer segment.
2. Margin Floor Enforcement
You set a minimum gross margin percentage per product, collection, or order total. Agentis enforces it at checkout. If an order — after all applied discounts, shipping subsidies, and taxes — would fall below your floor, the checkout is paused and you define the fallback behaviour: reject the discount, notify the customer, or escalate to a manual review.
3. MAP Protection
For brands with Minimum Advertised Price obligations, Agentis enforces MAP at the transaction level. It doesn't matter whether the discount came from a coupon, a bulk rule, or a channel-level promotion — if the final price breaks MAP, Agentis catches it.

Migration Steps: From Shopify Scripts to Agentis
The migration is straightforward and takes less than 30 minutes.
Step 1: Audit your existing Scripts. Log into your Shopify admin and go to Apps > Script Editor. Document every script you have active, noting which ones are doing margin-related work (discount caps, stacking prevention, MAP enforcement) versus pure UI logic.
Step 2: Migrate UI-only scripts to Checkout Extensibility. Scripts that only change labels, reorder options, or show/hide UI elements based on cart conditions can be rebuilt as Checkout UI Extensions. Shopify has a migration guide for this.
Step 3: Remove Scripts before June 30. Shopify will disable Scripts on June 30 regardless. Remove them yourself before the deadline so you can test the checkout without them and identify gaps in your protection logic.
Step 4: Install Agentis and configure your rules. Install the Agentis app from the Shopify App Store and connect it to your store. The onboarding flow walks you through:
- Setting margin floors by product or collection
- Configuring coupon stacking rules
- Entering MAP thresholds for relevant SKUs
Rules go live through Shopify Functions, so there's no custom code to maintain.
Step 5: Test in a development store. Run test orders with combinations that would previously have triggered your Scripts logic. Confirm Agentis catches them correctly before you go live.
Don't Wait for June 30
The merchants who will feel this most are the ones who built sophisticated margin logic into Scripts and haven't yet identified a replacement. If that's you, the window to migrate is now — not the last week of June when your dev team is scrambling.
