The Challenge

A mid-size logistics company ran 12 critical workflows manually: invoice data entry from PDFs, shipment status updates to clients, purchase order approvals, and weekly reporting. Employees spent 2,000+ hours monthly on these tasks with a 15% error rate causing payment disputes.

Our Solution

We mapped all 12 workflows and built automated pipelines using n8n (self-hosted) for orchestration. OCR with Python extracts data from PDF invoices with 99.2% accuracy. Automated email and Slack notifications replace manual status updates. All workflows include exception handling and audit trails.
