Shopify Scripts Deprecated: The Complete Migration Guide for 2026

If you’re a Shopify merchant using Scripts, the clock is ticking. Shopify has confirmed that all Scripts will stop working on June 30, 2026. Whether you’re running custom discount logic, shipping rules, or payment customizations through the Script Editor, you need a migration plan — and you need one now.

This guide covers everything you need to know: what’s changing, why Shopify made this move, how to plan your migration, and the fastest way to get it done without writing a single line of code.

Shopify Scripts — the Ruby-based customization layer that let Shopify Plus merchants write custom checkout logic — has been officially deprecated. Here’s the timeline:

Key Dates:

  • 2023: Shopify announces Shopify Functions as the successor to Scripts
  • 2024: Shopify begins recommending merchants migrate to Functions
  • August 2025: Original deprecation deadline (later extended)
  • June 30, 2026: Final deadline — all Scripts stop executing

You need to act if your store uses any of the following:

  • Line item Scripts — custom discounts on specific products (BOGO, volume, bundles)
  • Shipping Scripts — conditional free shipping, hiding/renaming shipping methods
  • Payment Scripts — hiding or reordering payment methods based on cart or customer conditions

If you’re not sure whether your store uses Scripts, check Settings → Script Editor in your Shopify admin. If you see active scripts there, you need to migrate.

After the deadline:

  • All Scripts stop executing — they simply won’t run at checkout
  • Your checkout reverts to Shopify’s default behavior
  • Discounts, shipping rules, and payment customizations created through Scripts disappear
  • There is no grace period after the deadline

Shopify Scripts vs Shopify Functions: What Changed?

Section titled “Shopify Scripts vs Shopify Functions: What Changed?”

Shopify Functions is the modern replacement for Scripts. While both customize the checkout experience, they work very differently under the hood.

FeatureShopify Scripts (Legacy)Shopify Functions (Modern)
LanguageRuby (interpreted sandbox)Rust/WASM (compiled, near-native speed)
PerformanceSlower, interpreted at runtimeSub-5ms execution, no cold starts
Plan requirementShopify Plus onlyAll plans (via apps)
SetupCode required (Ruby)No-code options available (via apps like PowerX)
Types availableLine items, shipping, payments8 types: discounts, shipping, payment, validation, cart transform, discount manager
Discount limitLimited by Script complexity750+ active discounts possible
MaintenanceManual code updatesVisual rule builder, no maintenance
Activity trackingNo built-in loggingFull activity log with revert (PowerX)

1. Performance is dramatically better. Scripts ran Ruby code in an interpreted sandbox at checkout. Functions use Rust compiled to WebAssembly, executing in under 5 milliseconds. This means faster checkouts and better conversion rates.

2. Functions aren’t Plus-exclusive. This is a major change. Scripts were locked to Shopify Plus ($2,300/month). Functions are available on all Shopify plans through apps, meaning Basic and standard Shopify merchants can now access the same powerful checkout customizations.

3. Functions cover more ground. Scripts had three types: line items, shipping, and payments. Functions add checkout validation (block checkout with custom errors), cart transform (merge items into bundles), and discount manager (manage discount codes programmatically). That’s 8 function types versus 3 script types.

4. No coding required. With apps like PowerX Functions Creator, you get a visual rule builder instead of writing Ruby code. This means faster setup, fewer bugs, and no developer dependency.

Here’s a practical migration plan you can follow regardless of your store’s complexity.

Before you can migrate, you need to know exactly what you’re migrating. Go to Settings → Script Editor in your Shopify admin and document each active Script:

  • What type is it? (Line item, shipping, or payment)
  • What does it do? (e.g., “20% off when buying 3+ items from Summer collection”)
  • What conditions does it check? (e.g., customer tags, cart total, specific products)
  • How critical is it? (revenue impact if removed)

Create a simple spreadsheet with these four columns. This becomes your migration checklist.

Step 2: Map Each Script to Its Functions Equivalent

Section titled “Step 2: Map Each Script to Its Functions Equivalent”

Every Script type has a direct equivalent in Shopify Functions:

Script TypeFunctions EquivalentPowerX Feature
Line item scripts (discounts)Product Discount functionProduct Discounts — volume, BOGO, bundle, conditional
Line item scripts (pricing)Product Discount functionConditional Discounts with set price or dynamic pricing
Shipping scripts (rates)Shipping Discount functionShipping Discounts
Shipping scripts (hide/rename)Shipping Customization functionShipping Customization
Payment scripts (hide/rename)Payment Customization functionPayment Customization

You have two options:

Option A: Custom development — Hire a developer to write Rust-based Shopify Functions from scratch. This is expensive ($5,000–$20,000+ depending on complexity), time-consuming (weeks to months), and requires ongoing maintenance.

Option B: Use a no-code app — Install an app like PowerX Functions Creator that provides a visual rule builder for all 8 function types. Migration takes minutes to hours instead of weeks, and no code maintenance is needed.

For most merchants, Option B is the clear winner — it’s faster, cheaper, and easier to maintain.

This is the critical step. For each Script on your audit list:

  1. Create the equivalent function in your chosen tool
  2. Configure the conditions to match your Script’s logic
  3. Test thoroughly — add items to cart, try different quantities, test with different customer accounts
  4. Compare results — verify the discount amounts, shipping options, and payment methods match what your Script produced

Since you can run Scripts and Functions simultaneously before the deadline, you can test Functions alongside your existing Scripts to verify identical behavior.

Once you’ve confirmed that your Functions produce identical results:

  1. Deactivate your Scripts in the Script Editor (don’t delete yet — keep as reference)
  2. Monitor checkout behavior for 48-72 hours
  3. Check order data to verify discounts are applying correctly
  4. Delete Scripts once you’re confident everything works

PowerX Functions Creator is built specifically to replace Shopify Scripts with a modern, no-code alternative. Here’s why thousands of merchants are choosing it for their migration:

Unlike competitors that focus on discounts only, PowerX covers every Shopify Function type:

  • Product Discounts — percentage, fixed, BOGO, volume, bundles, tiered, conditional
  • Order Discounts — cart-wide discounts with tiered spending rewards
  • Shipping Discounts — conditional free or reduced shipping
  • Shipping Customization — rename, hide, reorder shipping methods
  • Payment Customization — rename, hide, reorder payment methods
  • Checkout Validation — block checkout with custom error messages
  • Discount Manager (Plus) — manage codes, free gifts, cart attributes
  • Cart Transform (Plus) — merge items into bundles

This means you don’t need to install separate apps for different function types. One app handles everything your Scripts did — and more.

Shopify limits each store to 25 automatic discounts. PowerX breaks through this with 30+ campaigns per function, each generating its own automatic discount. That’s 750+ active discounts versus Shopify’s 25.

PowerX includes a Scripts-to-Functions migration tool available on all plans, including the free Starter plan. It guides you through mapping your existing Script logic to PowerX campaigns.

Instead of writing Ruby or Rust code, you use PowerX’s visual rule builder with 20+ condition types:

Every change is tracked with full diffs. Made a mistake? Revert any change or reset to any previous state instantly. No Script editor offered anything like this.

This is a game-changer. Your Scripts required Shopify Plus ($2,300/month). PowerX starts at $27.30/month on the Professional plan and works on Basic, Shopify, Advanced, and Plus plans. If you’re migrating and don’t need Plus for other reasons, this could save you significant money.

Ready to start your migration? Install PowerX Functions Creator — it’s free to start on development stores, and the Professional plan includes a 3-day free trial.

Shopify Scripts will be fully deprecated on June 30, 2026. After this date, all existing Scripts will stop executing at checkout. Shopify originally announced an August 2025 deadline but extended it to give merchants more time to migrate.

Do I need Shopify Plus for Shopify Functions?

Section titled “Do I need Shopify Plus for Shopify Functions?”

No. Unlike Scripts which were exclusive to Shopify Plus, Shopify Functions are available on all Shopify plans (Basic, Shopify, Advanced, and Plus) through third-party apps like PowerX Functions Creator. This is one of the biggest improvements — you no longer need a $2,300/month plan to customize your checkout.

Can I run Scripts and Functions at the same time?

Section titled “Can I run Scripts and Functions at the same time?”

Yes. During the transition period before June 30, 2026, you can run both Scripts and Functions simultaneously. This allows you to test your new Functions-based setup alongside existing Scripts before fully switching over. Both will execute at checkout, so be careful not to create conflicting discount rules.

What if my Script logic is too complex to migrate?

Section titled “What if my Script logic is too complex to migrate?”

PowerX Functions Creator supports 20+ condition types across all 8 Shopify Function types. Most Script logic — including complex tiered discounts, conditional BOGO, customer-specific pricing, and shipping/payment customization — can be replicated without code using the visual rule builder. For truly custom requirements, the Enterprise plan ($209.30/month) includes dedicated developer support to help with your specific migration.

It depends on complexity:

  • Simple Scripts (single discount rules): Minutes using PowerX’s visual rule builder
  • Moderate Scripts (multiple conditions, 2-5 scripts): 1-2 hours
  • Complex setups (10+ scripts with interdependencies): A few hours to a full day
  • PowerX includes a built-in Scripts-to-Functions migration tool on all plans to help streamline the process

Don’t wait until the last minute. The June 2026 deadline will arrive faster than you think, and migrating under pressure leads to mistakes. Start today:

  1. Install PowerX Functions Creator (free for development stores)
  2. Audit your existing Scripts
  3. Follow the Getting Started guide to create your first campaign
  4. Browse 28 real-world examples for configurations matching your Scripts
