Process receipts: Slack for contracts
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 contracts, around a "List Changed Docs (Google Drive)" step, in 21 documented nodes.
Process receipts with Google Drive for Contracts. An original, ready-to-import n8n workflow built around the 'File Processing' pattern for legal & compliance. It runs on a schedule and orchestrates 21 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. Your team sees the right data at the right time.
Key benefits
- ✓Keeps Slack and Google Drive in step for contracts, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Drive are skipped, across all 21 nodes of this contracts build
- ✓A failed Slack or Google Drive call is retried rather than dropped, at any of the 21 nodes in this contracts build
- ✓Every contracts run leaves an audit row behind, alongside Slack
- ✓Fans the same result out to Google Sheets in the same run, for contracts
Use cases
- →Teams keeping Slack and Google Drive aligned by hand for contracts
- →Answering contracts questions from your own indexed documents, then replying in Slack
- →Contracts work where "List Changed Docs (Google Drive)" is still a manual step before Slack
- →Contracts work that only reaches Slack on a schedule, when someone remembers to start it

What you'll learn
Production levelProduction-grade: idempotency, dead-letter handling, and reconciliation included.
- •Downloading and parsing CSV, XLSX, or PDF into JSON items
- •Archiving the processed file
- •Moving data between Google Drive, Slack and Google Sheets 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, HTTP / REST API). 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.
