SOC 2 Shopify Checkout Limits
Velocity, discount, and market-eligibility gates for Shopify checkout, B2B, and POS — with audit evidence for every exception.
For: Ecommerce ops and finance at SOC 2-scoped Shopify merchants
SOC 2 CC8.1SOC 2 CC6.1PCI-aligned evidence
What it enforces
Transaction velocity ceiling
Blocks or escalates a transaction above the unvetted ceiling unless the customer reputation is trusted.
Discount exception gate
Escalates discounts above threshold when contract-value evidence is missing.
Market eligibility check
Restrains B2B orders routed to a market the customer is not entitled to.

How to install it
The app evaluates checkouts and order admissions in read-only mode by default — no live behavior changes until you enable enforcement.
Shopify — shadow mode
1. Install "Decionis Margin Protection" from the Shopify App Store.
2. Pick a starter pack (margin guard / oversell prevention / refund threshold).
3. App is in read-only mode by default — every governed checkout / order
produces a signed Decision Dossier. No shopper-facing change.Ships in shadow mode — every verdict is recorded, nothing is blocked.
What to do next
This recipe is one step in a path. The same five steps apply to every recipe in the exchange.
- Simulate this recipe
Run the policy against a realistic action in the browser. Push it past what the rules allow and watch the verdict come back. No account.
- View the signed Decision Dossier
See exactly what was decided and why: the rule that fired, the evidence it read, the policy version in force, and an Ed25519 signature you can verify yourself.
- Deploy in shadow mode
Measure what the policy would have caught on your own traffic without touching the live path. Every recipe defaults to shadow, so the first deployment carries no execution risk.
- Connect a real workflow
Point the same policy at the system where the action actually originates — a checkout, an ERP posting, a Zap, an agent's tool call.
- Share the verified result
Publish the proof: a public verification link, an embeddable badge, a PR comment, or an anonymized shadow-mode finding. This is how the next person discovers Decionis.
