Shopify Plus × Checkout Functions Profit Governance
Shopify Scripts alternative for Shopify Plus: Agentis powers Shopify Functions migration with built-in profit governance and margin enforcement at checkout.
Shopify is deprecating Scripts in favor of Functions, and every Shopify Plus merchant faces a migration. Most merchants are treating this as a 1:1 port — recreating existing Script logic in Functions without adding new capabilities. This is a missed opportunity. The Scripts-to-Functions migration is the single best moment to add profit governance to your checkout because you are already rebuilding the logic. Starting from scratch in Functions means you can bake margin awareness into the foundation instead of bolting it on later. The merchants who port Scripts directly will have modern syntax running the same margin-blind logic. The merchants who use the migration to add Agentis will come out the other side with a checkout that actively protects profitability — and they will spend the same engineering hours either way.
Agentis provides a migration path from Shopify Scripts to Shopify Functions that adds profit governance as a first-class capability during the transition. Instead of porting your discount Scripts line-by-line into Functions, Agentis helps you decompose your existing Script logic into margin-aware Functions that combine your business rules with live COGS data. Every discount Function checks whether the resulting order margin clears your floor. Every payment customization Function factors in the real processing fee. Every cart transform Function considers the all-in cost. The migration effort is comparable to a direct port, but you emerge with a checkout that enforces profitability instead of just applying discounts blindly.
Agentis provides a Function scaffolding framework that wraps your business logic with margin evaluation. Each Function type (Discount, Payment Customization, Cart Transform, Delivery Customization) includes a margin-check middleware that resolves COGS from the Agentis metafield cache before executing your rule. The framework supports both Rust and JavaScript Function targets. Migration tooling includes a Script-to-Function analyzer that maps existing Script operations to their Function equivalents and identifies where margin checks should be inserted. All Functions are deployed via Shopify CLI and managed through the Agentis dashboard. The Shopify Scripts migration workflow is explicit: import your existing Script files, run the analyzer to produce a Shopify Functions migration plan, review the generated Function stubs, and deploy. Each stub ships with a profit-floor hook already wired in, so the Shopify Functions migration adds margin enforcement by default rather than as a follow-up project.
Shopify has announced that Scripts will be deprecated in favor of Functions as part of the Checkout Extensibility migration. The exact sunset date varies, but Shopify Plus merchants are encouraged to migrate now. Agentis helps you use this mandatory migration window to add profit governance rather than just porting legacy logic.
Agentis supports incremental migration. You can migrate one Script category at a time — for example, start with Discount Functions, then move to Payment Customization, then Cart Transform. Each Function can independently include margin enforcement while your remaining Scripts continue to run.
No. Agentis Functions support both Rust and JavaScript targets. Most merchants use JavaScript for faster iteration. Rust is available for merchants who need maximum performance on high-volume stores, but JavaScript Functions consistently deliver sub-10ms latency for typical SKU counts.
The Agentis Script-to-Function analyzer decomposes complex Scripts into discrete Function operations and preserves conditional logic. Tiered pricing, conditional discounts, customer-segment rules, and quantity breaks all translate to Functions. The margin check wraps the final output regardless of the logic complexity.
Agentis is designed as a complete Shopify Scripts alternative for the margin-sensitive parts of your checkout — discounts, payment customization, cart transforms, and delivery customization. The Shopify Scripts migration path preserves every rule you had in legacy Scripts and adds profit governance on top. For non-margin logic (shipping label generation, order routing, third-party app integrations), you continue to use the appropriate Shopify Plus tools; Agentis does not try to replace those. The goal of the Shopify Functions migration is to make the checkout margin-aware, not to absorb every backend responsibility.
