The glue between a sale and a delivered, licensed product. Checkout + Fulfillment Stack connects your payment processor to automatic file delivery and license issuance, with webhook handlers for common processors, an order-to-fulfillment flow, and email-delivery templates.

What's inside:

• Webhook handlers for common payment processors

• Order-to-fulfillment automation flow

• Auto license issuance on successful payment

• Email-delivery templates (order confirmation + access details)

• Failure/retry handling for missed webhooks

• Setup + configuration documentation

Who it's for: sellers who currently deliver products manually after a sale and want zero-touch fulfillment from payment to access.

Prerequisites: a VPS or Docker-capable host, Docker + Docker Compose, API keys from your payment processor, an email-sending service (e.g. SMTP credentials), basic Linux comfort. Setup: ~45-75 min. Self-hosted only — expect €5-15/mo hosting. Single-business-use code license. 7-day refund if setup fails after following the guide and contacting support first.
