Fowndr

Get paid inside the product, not via manual invoices only.

We connect Checkout to your user and order model where applicable, and keep metadata consistent so reconciliation isn’t a forensic exercise.

01.Checkout sessions

Configured for your price IDs and success/cancel paths—test mode in development, live keys only where they belong.

02.Metadata & references

Customer email, internal IDs, and source tags carried through so webhooks and your admin line up with reality.

03.Webhooks & edge cases

When webhooks are in scope, we handle idempotency patterns and failure visibility so duplicate events don’t create duplicate fulfillment.

04.Fulfillment handoff

Clear rules for what happens after payment: access granted, status updated, team notified, and how support can verify outcomes fast.

05.Refunds and reversals

We define what’s automated vs manual for v1 so reversals don’t leave your product state inconsistent with Stripe.

06.Security boundaries

Keys stay server-side, price IDs are controlled, and public endpoints are rate-limited so payment flows aren’t an attack surface.
