Invoice and accounting automation with AI
By Tom MrozekLinkedInHow AI reads invoices, codes them, posts them and sends them to the accountant. Real deployments in PL and CZ.
Invoice lands in inbox → AI extracts it, OCR + LLM → pulls vendor, amount, VAT, date → codes to account → pushes to your accounting system.
Stack: Mindee / AWS Textract (OCR) + GPT-4.1 (context) + n8n (orchestration) + accounting system API.
Accuracy: 95–99% on Polish and Czech invoices. Human only approves exceptions.
Time saved: 70–85% of bookkeeper work. At 500 invoices/month that's 60–80 hours saved.
Deployment: €6k–15k. Payback 4–8 months. GDPR compliant, EU processing.
