Invoice Processing Agent
SMB finance teams and outsourced bookkeeping firms
FinanceIntermediate8.94-6 weeks to MVP
Problem
Accounts payable is manual and error-prone. Someone retypes invoice lines, hunts for the matching purchase order, and chases mismatches by email.
Solution
An agent that ingests invoices from email or a drop folder, extracts line items, three-way matches them against purchase orders and receipts, flags only real discrepancies, and queues the rest for one-click approval.
