Checkout Platform

Checkout flows fail when pricing, payment state, fulfillment, and support visibility are designed as separate concerns.

The user-facing path needs to feel simple, but the system behind it still has to handle failed payments, webhook timing, order updates, and internal support questions.

The flow was modeled around the full order lifecycle, from cart state and payment intent to webhook handling and post-purchase communication.

I structured the concept around explicit states so the product can recover gracefully instead of hiding complexity until something breaks.

The platform concept uses a clean customer flow backed by explicit order states, recoverable payment handling, and webhook-driven fulfillment.

The admin side is designed to make support easier: what happened, what state the order is in, and what the next safe action should be.

The structure keeps the customer experience simple while giving internal teams enough visibility to debug payments and support orders.

It is the kind of product where good backend modeling directly improves the frontend experience.
