An invoice processing automation in Make reads incoming invoices from email or cloud storage, extracts key data (vendor name, amount, due date, line items, tax), logs it in Google Sheets or your accounting tool, and routes invoices for approval. On aidowith.me, the Automation in Make route walks you through 12 steps to build this workflow. You set up an email trigger or Google Drive watcher, add AI-powered data extraction that reads invoice PDFs and unstructured email text, map the extracted fields to your tracking spreadsheet, and configure approval routing based on amount thresholds. Invoices over a set amount go to a manager for approval via Slack. Smaller ones get logged automatically. The automation processes invoices in seconds instead of the 5-10 minutes each one takes manually. Teams typically save 8-12 hours per month. The full build takes about 2 hours with no coding required.

- AI extracts invoice data in seconds, whether the invoice is a PDF attachment or email text
- Automatic approval routing: invoices over your threshold go to a manager via Slack

Questions
Yes. The route uses AI modules in Make to parse PDF attachments and extract data like vendor name, invoice number, amount, due date, and line items. It works with both structured PDFs (from accounting software) and scanned documents, though structured PDFs give more consistent results.
Make has modules for QuickBooks, Xero, and FreshBooks. The route focuses on Google Sheets as the primary output, but shows you how to add an accounting software connection as an additional step. You can log invoices in both places simultaneously.
The error handling step routes unparseable invoices to a review queue (Slack message or email notification). You process those manually. In practice, AI handles 85-90% of standard invoices without issues. The route shows you how to improve parsing accuracy over time by adjusting your extraction prompts.
