# Invoice processing app on Replit

The author built Documind, an invoice platform, on Replit by prompting Claude, with extraction, anomaly detection, workflows, and plain-English queries.

Result: Documind extracts invoice data in under four seconds; a 130-invoice demo caught four anomalies, including an $875 duplicate and a 60% vendor price increase.

## How it was set up

Replit as the dev environment, prompting for the build. React, Vite, Node.js, Express, SQLite, and the Claude API for extraction and natural language queries.

## Worth knowing

Tested only on simulated invoices for a fictional coffee shop; the $7,800 yearly saving is the author's own estimate, not a measured result.

## Evidence note

Live Replit app link and demo figures; no independent verification
