FuelFlow turns receipt scans into verified reimbursement batches and scheduled payouts. A driver scans a receipt, an OCR pipeline extracts the merchant, date, amount, and fuel details, and the driver confirms before submitting. Duplicate and fraud checks run across image hashes, perceptual hashes, and OCR field matching, and a rules engine decides auto-approval, review, or flag based on confidence and company limits. Admins review flagged receipts, group approved ones into weekly or monthly batches, and release payouts once batches are clean and drivers are payout-ready. Reports export to accounting-ready CSV and PDF.
