Extract from receipts with Slack for invoices
Runs on a schedule across Slack, Google Drive and Google Sheets, looks the answer up in a vector store, then parses the incoming file into rows. Built for invoices, around a "List Changed Docs (Google Drive)" step, in 17 documented nodes.
Extract from receipts with Google Drive. An original, ready-to-import n8n workflow built around the 'File Processing' pattern for legal & compliance. It runs on a schedule and orchestrates 17 nodes across Slack, Google Drive, Google Sheets. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. The result is a hands-off process that just works.
Key benefits
- ✓Keeps Slack and Google Drive in step for invoices, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Drive are skipped, across all 17 nodes of this invoices build
- ✓A failed Slack or Google Drive call is retried rather than dropped, at any of the 17 nodes in this invoices build
- ✓Fans the same result out to Google Sheets in the same run, for invoices
- ✓Invoices answers come from your indexed content, not model recall, before reaching Slack
Use cases
- →Teams keeping Slack and Google Drive aligned by hand for invoices
- →Answering invoices questions from your own indexed documents, then replying in Slack
- →Invoices work where "List Changed Docs (Google Drive)" is still a manual step before Slack
- →Invoices work that only reaches Slack on a schedule, when someone remembers to start it

What you'll learn
Advanced levelAdds branching depth and audit logging on top of the core pattern.
- •Downloading and parsing CSV, XLSX, or PDF into JSON items
- •Archiving the processed file
- •Moving data between Google Drive, Google Sheets and Slack in a single run
Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.
Common questions
What exactly do I get?
The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.
How do I import it into n8n?
In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.
Do I need anything else for it to work?
You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Slack, Google Drive, Google Sheets). No coding is required.
What if it doesn't work for me?
If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.
Can I modify or resell it?
You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
