AI corporate expense governance & receipt intelligence
Overview
Expeno streamlines corporate spending by combining OCR receipt intelligence with custom expense approval hierarchies, automated policy compliance checks, and ERP accounting sync.
Employees spent hours manually transcribing receipts while finance teams had to chase missing itemized breakdowns and catch policy violations manually.
Created an AI-powered expense suite on Next.js, Node.js, and PostgreSQL that scans receipts with vision models, auto-fills expense forms, and routes approvals based on department limits.
