Approve documents for expenses
Starts when someone submits the form across Slack, Google Sheets and Telegram, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for expenses, around a "Stamp & Shape Invoice" step, in 14 documented nodes.
Approve documents with Telegram and Slack hands-free. An original, ready-to-import n8n workflow built around the 'Approval Workflow' pattern for finance & banking. It starts from a form and orchestrates 14 nodes across Slack, Google Sheets, Telegram. 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 Sheets in step for expenses, without anyone re-typing a row
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 14 nodes in this expenses build
- ✓Branches rejoin before Slack, so a expenses run reports once rather than 14 times
- ✓The pause before Slack is durable — a expenses run survives a restart
- ✓Fans the same result out to Telegram in the same run, for expenses
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for expenses
- →Expenses sequences that run over days and must survive a restart before Slack
- →Intake checked for completeness before it is stored in Slack, for expenses
- →Expenses work where "Stamp & Shape Invoice" is still a manual step before Slack

From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.

What you'll learn
Core levelA compact production shape: validation and error handling without extra machinery.
- •Pausing a workflow on a Wait node until a human decides
- •Embedding a resume URL so approving is one click
- •Branching cleanly on approve versus decline
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 Sheets, Telegram). 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.
