How the solution came together
01The business need
A skincare brand needed a complete store experience spanning product discovery, commerce logic and day-to-day catalogue administration.
02What needed to change
Build a complete skincare store: product discovery, customer accounts, reliable orders and an operational back office.
03How it works

- 01
Server-calculated totals, integer currency amounts and inventory reservations protect orders against price manipulation and overselling.
- 02
Idempotent order creation, transactional rollback and signed Stripe webhooks handle retries and payment-state changes. The payment flow was tested in the preview environment.
- 03
The admin panel supports catalogue work, orders and validated supplier CSV drafts. Public catalogue mode is separated from checkout and account writes.
The key decision
Keep pricing and stock authority in the backend and expose the public catalogue separately from protected commerce preview. This allows the brand experience to launch while checkout readiness remains explicit.
How we checked it
Server totals use integer currency amounts. Reservations, transactional rollback, idempotent order creation and signed payment webhooks protect the implemented order flow; payment scenarios were verified in preview.
