Carry final invoice corrections into Chaser
When someone spots a specific invoice detail and confirms the correction, Notis can update the existing record instead of leaving the fix in chat.
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 existing invoice's information using its unique identifier. use after confirming the invoice exists when you need to modify fields like status, amounts, or dates.
Why this helps
Small corrections are easy to lose among the messages about getting an invoice out the door.
- Capture confirmed fixes at the point they are discussed.
- Keep invoice records consistent with team decisions.
- Avoid acting on speculative or incomplete corrections.
Setup
Build it in a few focused steps.
- 1Connect Slack and Chaser to Notis once through the portal.
- 2Create an automation in the portal or ask Notis conversationally, telling it to update an existing invoice only when the correction is explicit, final, and tied to a clear invoice reference.
- 3Pick Slack Channel Message Received as the trigger and choose a channel for run reports.
- 4Test with one real correction and verify the intended invoice was updated.
