Invoice Processing Automation — End-to-End Guide

Invoice automation eliminates manual data entry by using AI OCR to extract invoice fields automatically. The process: invoice arrives (PDF/email/scan), OCR extracts all data fields, validation rules verify accuracy, the system posts to your ERP, and payment is scheduled. This complete workflow reduces processing time from 15 minutes to under 30 seconds per invoice.

Invoices arrive via email, upload portal, or EDI. Cargoffer OCR accepts PDF, image scans, and Excel formats. The system auto-detects invoice type and routes to the best extraction model. For high volumes use batch upload. For real-time processing use the API with webhook callbacks.

The OCR engine extracts: provider name and NIF, invoice number and series, issue and due dates, line items with descriptions, quantities, unit prices, VAT rates and amounts, totals, IBAN for payment, and payment method. For Spanish invoices, fields include NIF validation and IVA breakdown at 21, 10, and 4 percent rates.

Each extracted invoice goes through 2-pass verification. The system checks: VAT calculation matches (base times rate equals VAT amount), invoice total matches line-by-line sum, duplicate invoice number detection, PO number exists if required, and provider is in approved vendor list. Exceptions are flagged for manual review.

Validated invoices post automatically to your ERP. The field mapping connects supplier to vendor master, GL codes, tax codes, and payment terms. Integration supports SAP via BAPI, Odoo via external API, and Microsoft Dynamics via Common Data Service. See our integration guides for each ERP.

Approved invoices flow to the payment queue. The system schedules payment based on due date, captures early payment discounts, and prevents duplicate payments. Payment files can be generated for SEPA or wire transfer.

Manual invoice processing costs 8-15 EUR per invoice. OCR automation reduces this to less than 1 EUR. Payback period is typically 2-3 months for companies processing 200+ invoices per month. Start with our invoice extraction tutorial and scale up.
