🏗️ ERP Integration (Workflow Hint)

Since UpInvoice returns a perfectly structured JSON, a bot can easily take this data and send it to any ERP.

Recommended Workflow for the Bot:

1. Extract: Call process_invoice to get the JSON.
2. Review: Present the extracted data (Supplier, Date, Total, Lines) to the user for validation.
3. Map: Map the JSON fields to your ERP's API (e.g., Dolibarr, Holded, Factusol, SAP).
4. Push: Send the validated data to the ERP.

🤖 Bot Instructions (System Prompt Hint)

"When a user provides an invoice or receipt as an image or PDF, first convert it to a Base64 string. Then, call the process_invoice tool. Use the structured data returned to verify the information with the user or prepare it for upload to an ERP system."
