Keep Firmao invoice details aligned with Slack
Carry explicit corrections into the invoice record while the decision is fresh.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Update Invoice
Tool to update an invoice. Use when you need to modify an existing invoice by its ID after retrieving its details.
Why this helps
Invoice corrections can require switching tools and remembering to make the same change later.
- Reduce repeated entry of confirmed invoice corrections.
- Keep the invoice record aligned with a clear team decision.
- Avoid hunting through Slack to confirm what changed.
Setup
Build it in a few focused steps.
- 1Connect Slack and Firmao to Notis once through the portal.
- 2Create a portal automation or ask Notis to apply explicit invoice corrections from Slack to Firmao.
- 3Describe in one prompt which confirmed corrections qualify and how to identify the invoice.
- 4Select the Slack Channel Message Received trigger and choose a run-report channel.
- 5Test with a real, non-sensitive correction example and review the invoice update.

Instruct Notis to act only on clear, confirmed corrections and only when it can identify the invoice and intended change.
Does this create a new invoice?
No. This workflow updates an existing invoice through Firmao's update action.
