Invoice Processing Workflow
An end-to-end automated pipeline that extracts data from PDF and image invoices, validates against POs, and pushes clean records to accounting systems.
The challenge
Why it exists
This workflow is suitable for individuals, businesses, and operations teams looking to automate their invoice intake and data capture process without writing custom code.
The approach
How it works
The Invoice Processing Workflow is an automated end-to-end pipeline built on n8n that streamlines invoice data extraction and management. The system accepts invoices in PDF or JPG format uploaded to a designated Unprocessed folder in Google Drive and supports two execution modes — single file processing via an automatic trigger and full batch processing via a manual trigger. Each file is downloaded and parsed using LlamaIndex Cloud, followed by structured data extraction through a GROQ-hosted large language model. The extracted invoice attributes are automatically appended to a Google Sheet for centralized record-keeping. Once processed, files are moved to a Processed folder in Google Drive and deleted from the Unprocessed folder, maintaining a clean and organized workspace. This workflow eliminates manual data entry, reduces human error, and delivers a fully auditable, scalable invoice management system — requiring no custom code or backend infrastructure.
