The problem

Small merchants stitch together spreadsheets, payment screenshots, and manual reminders. FeeGoat creates a region-aware billing workflow around the rails they already use—UPI in India and Zelle in the US—with automatic reconciliation and dunning.

What the system does

Capability with an operating model.

Region-aware onboarding and UPI/Zelle-first payment configuration

Razorpay Route and Stripe Connect for card and bank payment options

Bank-notification parsing, invoice matching, and automatic paid-state updates

Rule-based WhatsApp and email dunning sequences

Merchant, admin, support, payment, and customer self-service portals

GST-aware invoicing, bulk import, audit logs, and tenant isolation

Architecture

How it fits together.

Async FastAPI and SQLAlchemy services backed by PostgreSQL

Celery + Redis workers and schedules for reconciliation and messaging

React/TypeScript dashboard with TanStack Query and Recharts

Docker Compose deployment behind Nginx with TLS

Key decisions

Local rails first

The product defaults to the payment behavior small merchants already understand in each region.

Reconcile from evidence

Bank notifications are parsed and matched into invoice state instead of relying on manual screenshots.

Multiple operating surfaces

Merchants, platform operators, support staff, and customers each receive purpose-built portals.
