n8nAI Invoice Processor — Gmail PDF Extraction → Google Sheets + Slack — n8n Workflow Template
n8n Automation Template · Instant download · USD$34.98
Processing invoices manually is one of the most expensive wastes of time in any small business.
The AI Invoice Processor n8n template eliminates it entirely. Every hour, the workflow checks your Gmail inbox for emails containing invoices or receipts. When it finds one with a PDF attachment, it sends the PDF to GPT-4 Vision — which reads the document and extracts every key field: vendor name, invoice number, invoice date, due date, currency, subtotal, tax, total, line items, and payment terms. All data is appended as a clean row in your Google Sheets invoice log, and a formatted summary is posted to your `#finance` Slack channel so nothing gets missed or paid late.
What's included:
- Ready-to-import workflow.json for n8n (cloud or self-hosted)
- Full step-by-step README with Google Sheets column structure
- GPT-4 Vision PDF data extraction (handles scanned and image-based invoices)
- Gmail search filter (customisable by sender, subject, or label)
- Google Sheets invoice log with 17 auto-populated fields
Perfect for: Small business owners, finance teams, bookkeepers, freelancers, and agencies managing multiple vendor invoices monthly.
