Turn messy docs into clean data. Automate intake, OCR, extraction, routing, and approvals so invoices, contracts, and forms move faster with fewer errors.
A workflow captures a document from places you already use, like Gmail attachments, a Google Drive folder, or an n8n Webhook upload. It then runs OCR and extraction (often with OpenAI) to pull fields such as vendor, invoice number, dates, totals, or client details. Next, it validates and enriches the data, for example matching a vendor list in Google Sheets. Finally, it routes the result for approval or files it correctly, with a clear audit trail.
Usually, no. Most Flowpast workflows are plug-and-play: connect your accounts, pick folders or labels, and map a few fields. If you can run a Zapier automation, you can run this. For edge cases (weird scans, custom templates, compliance rules), you may want light editing in n8n, but itβs mostly point-and-click. You will also get better results when you can describe what βgood dataβ looks like.
If you process documents daily, automation often cuts the busywork in half. Think: no more renaming files, copying invoice totals, or chasing missing fields. A common setup saves about 2 hours each week for a small team, and much more when you handle lots of client paperwork. The bigger win is fewer errors and faster turnaround, which means fewer billing disputes, fewer missed deadlines, and less βwhere is that file?β panic.
Youβll need an n8n instance (cloud or self-hosted) and access to the apps you want to connect, like Gmail, Google Drive, and Google Sheets. For AI extraction, youβll also need an API key for OpenAI (or another supported model via OpenRouter). Start with 5β10 sample documents, including a couple messy ones, and define the exact fields you want output. Then run tests, review the extracted data, and add a simple human approval step where accuracy matters.
