Your store is shipping orders that lose money. Stop them in <10ms. Without losing sales.
Every stacked coupon that slips through checkout is margin you already earned, given away. Three guardrails (coupon stacking, margin floor, and MAP) intercept discount abuse before payment processes — every order checked in real time against your cost data. Built for $250K–$5M Shopify stores that run promotions and want to know which discounts are eating the margin.

What is Agentis?
Agentis is a real-time margin protection app for Shopify and Shopify Plus. It checks every checkout against your cost data in under 10 milliseconds and stops the three most common margin leaks at the source: stacked coupon codes, MAP violations, and orders below your margin floor. Built for Shopify stores doing $250K–$5M annual GMV that want margin enforcement without a developer or storefront code changes.
By Herzel Mishel, Founder of Agentis · Last updated July 2026
Your Shopify store leaks margin in three silent ways.
None of them trip an alert. Together they explain why the month-end number never matches what the dashboard showed during the sale.
Stacked coupons eat your margin silently
Customers combine WELCOME10 and SAVE15, and the cart total slips below cost. Shopify doesn't flag it, so the order ships and you only find the loss in the month-end report.
MAP violations slip through checkout
A discount code pushes a SKU below your manufacturer's minimum advertised price. The order goes through, and the vendor relationship you rely on takes the hit.
Every promo runs without a floor
Sitewide sales have no margin guardrail. High-volume discount days are exactly when stacking is worst, and they can become your most margin-destroying days with no alert at all.
Three guardrails. One integration.
Agentis checks every Shopify checkout against your cost data in real time. When a cart breaks a guardrail, it removes the lowest-value discount and lets the order through, so the customer keeps their best offer and you keep the margin.
Coupon stacking
When two or more codes combine to push a cart below your floor, Agentis removes the lowest-value one before payment. The customer keeps their best valid offer; you keep the margin.
<10msMargin floor
Any cart whose discounts drop net margin below your threshold gets corrected, not cancelled. Set one floor store-wide or per SKU. Orders keep flowing; the bad math doesn't.
<10msMAP protection
When the effective price after discounts would fall below your MAP agreement, Agentis holds the line automatically, protecting your authorized-dealer status at every checkout.

Works on every Shopify plan. Deeper on Shopify Plus.
Standard Shopify stores connect via the Agentis app in under 30 minutes, with no theme edits and no developer. Shopify Plus merchants unlock additional checkout extensibility hooks that run margin guardrails at the validation layer, before the payment step renders. Enforcement happens earlier in the flow, with no visible latency and no impact on conversion.
Shopify stores whose Scripts stopped executing on June 30, 2026 can migrate their discount guardrail logic directly into Agentis, with no Ruby dependency, no storefront code changes, and broader margin enforcement than Scripts allowed.
Tighter guardrails, flat conversions.
Methodology: 5% holdout cohort across 1,847 orders over 30 days on an illustrative Northwind Goods demo store (March–April 2026). Conversion variance between protected and unprotected groups: ±0.4% (not statistically significant, p > 0.10). Net margin lift on protected carts: +12.0%. The experiment used the built-in holdout cohort, available on every Agentis plan.

Common questions about margin enforcement
What is Shopify margin protection?
Shopify margin protection is a class of app that evaluates each checkout against your cost data in real time and blocks orders that would breach your margin rules, typically caused by stacked coupons, MAP violations, or below-floor discount combinations. Agentis is a margin protection app built specifically for Shopify and Shopify Plus.
How much does Shopify margin protection cost?
Agentis is offered in three tiers sized by store: Shop Starter (up to $250K annual GMV), Shop Plus (up to $1M GMV), and Shop Pro (up to $5M GMV). Pricing is quoted per store, so contact sales for your tier. There are no long-term contracts, and stores above $5M GMV move to an enterprise plan.
Will guardrails hurt my conversion rate?
No. A 5% holdout cohort across 1,847 orders over 30 days on the Northwind Goods demo store showed identical conversion rates between protected and unprotected groups (±0.4%, not statistically significant). Guardrails only block carts that would have lost money; customers with valid orders are never affected.
How do you connect to Shopify?
Via the Agentis Shopify App (one-click install) or direct API integration. Setup takes under 30 minutes. No changes to your theme or checkout flow required, and no developer needed.
How long does installation take?
Most Shopify stores are live in under 30 minutes. All three guardrail rules (coupon stacking, MAP, and margin floor) ship pre-configured with sensible defaults you can tighten later.
Does Agentis work with Shopify Plus?
Yes. Shopify Plus merchants get access to additional checkout extensibility hooks for deeper guardrail enforcement at the validation layer. Standard Shopify plans are supported via the app.
What's the difference between Agentis and Shopify Scripts?
Shopify Scripts required Ruby code and was deprecated on June 30, 2026 and no longer executes. Agentis is a no-code replacement that runs faster (<10ms vs. ~30–50ms), enforces margin floors and MAP that Scripts cannot, and survives the Scripts sunset with broader functionality and zero migration risk.
Does Agentis work with my ERP or NetSuite?
Yes for cost data. Agentis imports COGS via CSV, Shopify product metafields, or direct ERP integration (NetSuite supported via Celigo on enterprise plans). Small-store plans typically use CSV or metafield-based COGS.
Can I run Agentis on multiple Shopify stores?
Yes. Each Shopify store is connected separately so guardrail rules and cost data stay store-specific. Multi-store discount via volume; contact sales for two or more stores.
Can I run a holdout experiment?
Yes. Every Agentis plan includes a holdout cohort feature so you can compare margin-protected Shopify carts against an unprotected control group side by side. Default cohort size is 5%, configurable per store.
