Enforce Profit Floors at Shopify Plus Checkout in Under 10ms

Agentis uses Shopify Plus Checkout Extensibility to evaluate every order's true margin before confirmation — blocking, redirecting, or flagging orders that violate your profit floor.

How It Works

Agentis deploys as a Shopify Plus Checkout Extension using the Checkout Extensibility API. When a customer reaches the payment step, Agentis evaluates the cart against live COGS, shipping costs, payment method fees, and any stacked discounts. If the order falls below your configured profit floor, Agentis can block the checkout, remove the offending discount, suggest an alternative, or flag it for manual review — all within 10ms so the customer experience is unaffected.

Data Flows

  • →Cart line items, quantities, and applied discounts from Shopify → Agentis evaluation engine
  • →Discount codes and automatic discounts from Shopify Scripts → Agentis stacking detection
  • →Order confirmation webhook from Shopify → Agentis margin analytics dashboard
  • →Customer segment and tag data from Shopify → Agentis rule engine for tiered enforcement
  • →Enforcement decisions from Agentis → Shopify checkout UI (block, warn, or modify)

Benefits

  • Catch discount stacking and promo abuse before the order is confirmed, not after
  • Sub-10ms evaluation means zero impact on checkout conversion rates
  • No changes to your Shopify theme or storefront code — Agentis runs server-side
  • Full compatibility with Shopify Scripts, Functions, and custom checkout flows

Setup

  1. 1Install the Agentis app from the Shopify Plus partner dashboard
  2. 2Configure profit floor rules — by SKU category, customer segment, promo type, or zone
  3. 3Choose enforcement actions: hard block, soft warning, discount removal, or flag-only mode
  4. 4Run a 48-hour shadow mode to validate enforcement decisions before going live

Technical Details

Agentis integrates via the Shopify Plus Checkout Extensibility API (formerly Checkout.liquid, now Function-based). The extension runs as a Shopify Function deployed to your store, executing margin logic server-side with sub-10ms latency. We use the Cart Transform API for discount modifications and the Payment Customization API for conditional payment method logic. Webhooks on orders/create and orders/updated feed the Agentis analytics pipeline. All data transmission is encrypted via TLS 1.3.

Frequently Asked Questions

Does Agentis work with Shopify Scripts and Functions?

Yes. Agentis reads the output of Shopify Scripts and Functions to understand what discounts have been applied, then evaluates the combined margin impact. It works alongside your existing discount logic, not in place of it.

Will Agentis slow down my checkout?

No. Agentis evaluates orders in under 10ms using pre-cached cost data and optimized Shopify Functions. We monitor P99 latency continuously and guarantee no measurable impact on checkout completion rates.

Can I use Agentis on a non-Plus Shopify store?

Checkout Extensibility is a Shopify Plus feature. Agentis requires Shopify Plus for real-time checkout enforcement. Non-Plus stores can use Agentis in analytics-only mode via the Orders API.
