⚠️ The TL;DR

• June 30, 2026: All Shopify Scripts stop executing during checkout
• Affected: Any Shopify Plus store using Script Editor for discounts, shipping, or payment rules
• Impact: Checkout reverts to default behavior — no discounts, no shipping customization, no payment filtering
• Fix: Migrate to Shopify Functions before the deadline

Who Is Affected?

Only Shopify Plus merchants who use Script Editor. If you're on Basic, Shopify, or Advanced plans, you've never had access to Scripts and this doesn't affect you.

To check if you're affected:

Go to Shopify Admin → Apps → Script Editor
If you see active scripts listed, you're affected
If Script Editor isn't installed or you have no active scripts, you're fine

Common signs you're using Scripts:

• Automatic discounts that aren't set up in Shopify's Discounts page
• Shipping methods that appear/disappear based on cart contents
• Payment options that change based on order value or customer tags
• VIP/wholesale pricing tiers
• Buy-one-get-one or tiered quantity discounts

What Exactly Breaks?

After June 30, 2026, Shopify will stop executing Ruby scripts during checkout. Here's what that means for each script type:

Line Item Scripts (Discounts)

Before: Automatic discounts apply at checkout (BOGO, tiered pricing, VIP discounts, bundles)

After: All items show full price. No automatic discounts. Customers see higher totals. Abandoned carts spike.

Shipping Scripts

Before: Express shipping hidden for small orders, free shipping shown for large orders, rates renamed

After: All shipping options visible. Confusing rate names. Potential customer complaints about shipping costs.

Payment Scripts

Before: COD hidden for high-value orders, payment methods reordered by preference

After: All payment methods visible in default order. May expose options you don't want for certain orders.

The Financial Impact

This isn't just a technical migration — it's a revenue risk:

Lost discounts = lost conversions. If your BOGO offer suddenly disappears, customers who expected it will abandon checkout. Depending on how many orders use script-based discounts, this could mean 10-30% revenue drop on Day 1.
Customer service flood. "Why isn't my VIP discount working?" "I was supposed to get free shipping." Expect a support ticket surge.
Broken partner/wholesale pricing. If you use Scripts for B2B pricing tiers, wholesale customers will see retail prices.

Your Migration Checklist

Audit all active scripts in Script Editor

Analyze each script for complexity (use ScriptShift or manual review)

Prioritize by business impact (discount scripts first)

Generate Shopify Function code (or hire a developer)

Test Functions on a development store

Compare behavior: run Scripts and Functions side by side

Deploy Functions to production

Verify discounts appear correctly in live checkout

Disable old Scripts (they'll be force-disabled June 30 anyway)

Monitor for issues in the first week

Will Shopify Extend the Deadline?

Unlikely. Shopify has been warning about this since 2023 and has pushed the date back once already (originally planned for 2025). The Functions API is mature, tooling is available, and Shopify has invested heavily in the new architecture.

Don't bet on an extension. Start migrating now. Even if they push it back, you'll have better, more maintainable code running on the modern platform.

How Long Does Migration Take?

Scenario	Manual	With ScriptShift
1 simple script (BOGO, % off)	2-4 hours	15 minutes
3-5 moderate scripts	1-2 weeks	1-2 days
10+ complex scripts (enterprise)	1-3 months	1-2 weeks
Agency (multiple clients)	Months	Days per client

Don't wait until June

Every week you wait is a week less for testing. Start your migration today — analysis is free.
