Skanda Billing

A small accounting practice was processing hundreds of supplier bills a month — half by hand, half by guesswork. Multiple businesses ran through one mailbox, and credit limits were tracked in someone’s head.

A multi-tenant backend that ingests bills via OCR, extracts structured fields, applies tenant-specific credit rules, and produces auditable invoices and reports. Every action is logged; every tenant is isolated.

• ▸FastAPI service with strict Pydantic schemas and OpenAPI docs
• ▸PostgreSQL + SQLAlchemy + Alembic migrations
• ▸JWT auth with role-based access control
• ▸OCR pipeline for bill ingestion with confidence-scored review queue
• ▸Audit log on every state-changing endpoint
• ▸Reporting endpoints for credit, delivery orders, and proxy invoices

OCR alone is not enough. The win came from a tight review UI for low-confidence extractions — humans correcting the model is what made the data trustworthy enough to bill on.
