n8n Invoice Extraction Pipeline

DB Realm Inc. (Internal)

Challenge

Invoices accumulated across Google Drive folders in various PDF formats, requiring manual data entry into the financial tracking system — a time-consuming and error-prone process.

Solution

Built an n8n workflow automation pipeline that monitors Google Drive folders, extracts invoice data from 135+ PDFs using pattern matching and AI-assisted parsing, validates extracted data, and loads it into Oracle using bind variables and staging tables.

Results

  • ✓ 135+ PDFs automatically processed
  • ✓ Google Drive folder monitoring
  • ✓ AI-assisted data extraction
  • ✓ Oracle staging tables with validation
n8n Google Drive Oracle PDF Extraction Automation

The n8n Invoice Pipeline demonstrates the power of workflow automation for document processing. By combining Google Drive monitoring, PDF extraction, and Oracle database loading into a single automated flow, it eliminated hours of manual data entry.

Data for Good Calgary — HubSpot to Mautic Migration

A volunteer-run non-profit was paying for a commercial marketing platform while using only a fraction of it. The subscription covered a full CRM suite, but the chapter's actual usage was a couple of public web forms, an occasional newsletter, and consent tracking — the relationship-management side of the product sat entirely unused. For an organization running on donated time and a minimal budget, the recurring cost was hard to justify against what it delivered.
