AI-Powered Data Extraction & Validation for Colombian Invoices

LLM Chain
Complex Trigger

This n8n workflow automates the comprehensive processing of Colombian invoices. It efficiently handles multiple invoices by first splitting them into individual items using the 'Split In Batches' node. The core intelligence is provided by an 'OpenAI Chat Model,' which meticulously extracts key information from each invoice. This includes identifying critical data points such as vendor details, invoice numbers, dates, line items, quantities, unit prices, subtotals, tax amounts, and the total due. To ensure accuracy and consistency, the workflow then leverages a 'Calculator' tool to perform or validate numerical computations found within the invoices. This streamlined, AI-driven approach significantly reduces manual effort, enhances data quality, and accelerates the financial reconciliation process for Colombian documents.
