Invoice Automation

Processing a single invoice manually costs an average of €12–15 and takes 8–14 days. With 10,000 invoices per year, that adds up to €120,000–150,000 — just for data entry, verification, and approval. AI reduces this to under €2 per invoice.

OCR and Intelligent Document Recognition

From OCR to IDP

Simple OCR (Optical Character Recognition) recognizes text — nothing more. Intelligent Document Processing (IDP) understands context:

• Layout recognition: Where are invoice number, amount, tax rate, due date?
• Entity extraction: IBAN, VAT ID, supplier name, line items
• Table extraction: Individual items with quantity, price, total amount
• Multi-format: PDF, scan, photo, email attachment, ZUGFeRD, XRechnung

Accuracy 2026

Modern IDP systems achieve:

• Structured invoices (standard layout): 95–98% field accuracy
• Semi-structured invoices: 85–92%
• Handwritten receipts: 70–80% (better with fine-tuning on own receipts)

Tools: ABBYY Vantage, Kofax, Rossum, Klippa, or open-source (Donut, LayoutLM).

Invoice Matching

Three-Way Matching

AI automates the matching between:

1. Purchase order
2. Goods receipt
3. Invoice

If all three match → automatic approval (straight-through processing).

AI-Powered Tolerances

Instead of rigid rules ("deviation > 1% → manual review"), AI learns:

• Which suppliers regularly have slight deviations (rounding differences)
• Which product categories normally have quantity deviations
• Which price fluctuations are seasonally acceptable

Result: The straight-through processing rate increases from typically 30% to 65–80%.

Approval Workflows

Intelligent Routing

AI optimizes the approval process:

• Auto-approve: Invoices below threshold + known supplier + PO match → immediate approval
• Smart routing: Invoice goes to the right approver (based on cost center, amount, supplier)
• Escalation: Overdue approvals are automatically escalated
• Duplicate detection: AI detects duplicate submissions (even with slightly modified amounts)

Compliance Checks

AI automatically verifies:

• VAT ID validation: Is the tax number valid? (VIES query)
• Sanctions lists: Is the supplier on a sanctions list?
• Contract terms: Do payment terms and prices match the contract?
• Budget check: Is there still budget available on the cost center?

ROI Calculation

Discount effect: Faster processing means capturing more early payment discounts. With €10M procurement volume and 2% discount, that's up to €200,000 savings per year — just through faster processing.

Quick win: Start with your top 20 suppliers (they typically account for 80% of volume). Train the IDP system on their invoice formats, then scale.
