Gmail + Google Sheets: invoice approvals, logged clean
Invoices from Gmail and Google Drive get captured, approved by email, and logged in Google…
Automate receipt capture, OCR, and expense logging so you stop chasing paperwork. Route approvals, sync to Sheets or QuickBooks, and keep records audit-ready in minutes.
A workflow collects receipts from places you already use, like Gmail, Google Drive, or an n8n Form. It then runs OCR to read the receipt and uses AI (often OpenAI) to pull out fields like merchant, date, total, tax, currency, and category. Next, it validates rules you set, flags duplicates, and routes approvals if needed. Finally, it logs the expense to Google Sheets or pushes it into accounting tools, keeping the original file attached for audit trails.
Usually no. Most workflows are plug-and-play: connect your accounts, map a few fields, and youβre live.
For many teams, it cuts receipt admin in half. Instead of manually downloading attachments, typing totals, and chasing missing info, receipts are captured and logged as they arrive. Approvals also move quicker because the right person gets a ping with the key details. If you handle about 50 receipts a month, you can often win back about 2 hours at minimum, and month-end becomes far less stressful.
Youβll need an n8n workspace and access to the apps you want to connect (for example Gmail, Google Drive, and Google Sheets). If the workflow uses AI extraction, you will also need an OpenAI API key or a compatible provider. Have a simple chart of categories ready (travel, ads, software, meals), plus your approval rules. From there, you import the workflow, test with about 5 sample receipts, then turn on the trigger.
