Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartGuard adds a checkout rule that stops an order when the cart holds a product you marked as not for sale. Mark a product with a tag, or switch on Block checkout for that one product. You can also block a product type, vendor, or theme template. Approved buyers still get through: exempt customers by tag, exempt one customer, or exempt every B2B buyer. Give a product a date and it starts selling that day.
Decionis is a deterministic checkout action gate for Shopify. Preview and enforce payment, discount, order-limit, inventory, catalog, and margin rules inside Shopify admin. Shopify Functions apply checkout guardrails, while signed Decision Dossiers explain which rule triggered and why. Start in read-only Shadow Mode and enable enforcement only when ready.
- Block checkout by tag: Choose from preset tags or use your own
- Block by product type: Block entire product categories at once
- Block by template: Automatically tag products using a specific template suffix
- Custom error messages: Personalize the message customers see
- Allow, block, or escalate checkout actions with deterministic rules
- Catch catalog drift and promotion stacking before orders complete
- Generate signed Decision Dossiers that explain governed actions
- Preview impact in Shadow Mode before enabling enforcement
