Start with something you can deliver
Define the price, supported network, delivery action and after-sales process. Once payment is confirmed, your business grants a download or activates access and keeps the order available for lookup.

WHAT WE CAN BUILD WITH YOU
Your market. Your version.
These are customization directions. We agree what to retain, adapt and add before preparing an implementation proposal and quote.
01
Digital download storefront
Connect payment notifications to download access and tailor delivery, order emails and customer lookup.
02
SaaS access sales
Map a one-time purchase to plan access and an expiry date. Scope automatic renewal separately.
03
A branded payment business
Customize merchant onboarding, fees, checkout design and reconciliation exports around your merchant audience.
BUILT BEHIND THE EXPERIENCE
See how the workflow is built.
01
Checkout and SDK
A browser SDK connects sites to checkout. Server-side quotes help protect payment amounts from frontend changes.
02
Confirmation and notifications
Backend workers follow confirmation state and deliver signed Webhooks, with retries for failed notifications.
03
Orders and after-sales
MySQL records connect settlements, access delivery and refunds. The demo covers deduplicated fulfillment after notification retries.

What I’m building here
My development focus connects checkout, confirmation, signed notifications and merchant fulfillment, including recovery records when notifications fail.
Checkout and SDK
Confirmation and notifications
Orders and after-sales
Why not deliver immediately after payment?
Verify the notification and current order, then deduplicate by event and order. The demo recovers a failed receiver while repeated notifications still lead to one fulfillment; payment and delivery keep separate states.
What comes next
Further work includes real-wallet compatibility and business integration.
