This n8n workflow automates invoice handling from Telegram. When a user sends a PDF, it’s processed via LlamaIndex OCR, parsed with an LLM (LangChain), and structured into JSON. The data is logged in Google Sheets and—if approved via Telegram—sent to SAP Business One through the Service Layer API. Includes header/line item splitting, confirmation prompts, and SAP integration for seamless invoice creation.
