AI-Powered Invoice Verification
for Lark Expenses
Kopi uses Claude AI vision to read every invoice — PDF or image — and cross-validate amounts, dates, and vendor details against the expense form automatically. Errors are caught before they reach the approver.
AI field extraction
Claude AI reads invoices and extracts seller name, invoice number, date, line items, subtotals, tax, and total — even from scanned images and handwritten receipts.
Amount cross-validation
The invoice total is compared against the expense form amount. Any mismatch — including currency conversion errors — is flagged red for human review.
Date validation
Invoice date is checked against submission date. Future-dated receipts, date gaps exceeding your policy, and suspicious timing are automatically flagged.
Duplicate detection
Kopi checks if the same invoice has been submitted before. Duplicate claims are flagged before approval — eliminating a major source of expense fraud.
Vendor matching
Vendor name on the invoice is compared against the expense form. Mismatches — like submitting an Uber receipt for a hotel claim — are caught automatically.
Confidence scoring
Each extracted field gets a confidence score. Low-confidence extractions (e.g., unclear scans) are escalated for human review rather than auto-approved.
