A custom online store built to replace an outgrown off-the-shelf setup, with real payment integrity, reporting, and reconciliation built in from day one.
The Challenge
A growing merchant had outgrown a plugin-based store. Orders and payouts didn't always tie out, reconciling revenue was a manual chore, and the reporting they needed to run the business simply wasn't there. Every new feature meant fighting the platform instead of building on it.
Our Approach
We built a custom commerce platform on Python and Flask with PostgreSQL and Redis, using Stripe Connect for payments. The design put payment integrity first: background workers reconcile every order against the payment processor, so revenue always ties out and nothing slips through a webhook gap. A staging mirror plus a migrate-first deploy process means changes ship safely, without risking live orders.
Key Features
- Stripe Connect payments with destination charges and webhook-driven order capture
- Automated reconciliation that catches missed or mismatched payments before they become accounting problems
- A pricing and catalog engine tailored to the merchant's product model
- Reporting built for the way the business actually operates
- A full staging environment and safe, repeatable deploys
- Revenue that reconciles cleanly instead of by hand
- A fragile plugin stack replaced with a platform the business owns and can extend
- Room to add features without fighting someone else's framework
