Revolutionize your invoice management with our powerful workflow that automates the processing of invoices received via Telegram. By leveraging LlamaIndex OCR and integrating seamlessly with SAP Business One, this solution simplifies data extraction and enhances efficiency. Say goodbye to manual data entry and hello to automated accuracy.

What This Workflow Does

• Receive Invoices via Telegram: Easily receive PDF invoices directly through Telegram. A dedicated Telegram Trigger node actively listens for new messages, downloading and preparing documents for further processing.
• OCR with LlamaIndex: The invoice is uploaded to the LlamaIndex OCR API for text recognition. Our workflow monitors the OCR processing status until completion, allowing you to fetch results in Markdown format.
• Data Extraction with LLM: Convert the Markdown content into structured JSON using LangChain's language model. The Structured Output Parser ensures that all data is organized and editable for further use.
• Save to Google Sheets: The structured data is split into main invoice metadata and individual line items, storing each in specific tabs of a connected Google Sheets file for easy access and analysis.
• Ask for SAP Confirmation: To finalize processing, the bot communicates with the user through Telegram, confirming if they wish to send the data to SAP.
• Push Data to SAP B1: Upon user approval, the workflow connects to SAP Business One via its Service Layer API, rebuilding the invoice structure as needed for SAP integration.
