The problem
A subscription web platform needed real billing logic, plan upgrades, proration, and webhook-driven state changes, plus live chat, delivered under agency deadlines.
What was built
- Full concept-to-launch delivery as part of a five-application agency workload
- Stripe billing implementation covering plan upgrades, proration, and webhook-driven state changes
- SMTP service built for automated subscription and billing-cycle notifications
- Integrated chat functionality inside the subscription platform
Built on: Wix Velo · Stripe · Webhooks · SMTP
