🖼️ Tesseract OCR extracts all invoice data

Our API uses integrated Tesseract OCR to extract text from scanned images. Our AI then identifies key data such as:

• ✔ Sender, recipient (IBAN, VAT ID)
• ✔ Invoice number, date, line items
• ✔ Net, tax and gross amounts – structured output

🔄 Output: Valid ZUGFeRD XML (DIN EN 16931)

The API responds with a valid XML document – conforming to the ZUGFeRD standard. You can directly pass it to:

• 📦 your ERP or inventory system
• 📑 invoice archive or accounting interface
• ⚙️ digital inbound processing workflows

💻 Integration into scan workflows & mailroom automation

• 🖨 Scan-to-Folder → Script → FastAPI
• 📬 Scan incoming mail → convert to XML
• ⚙️ Batch convert folders via PowerShell
