Turn invoice approvals in Slack into Chaser invoices
Once a teammate gives the go-ahead in a channel, Notis can check for the customer and create the invoice in Chaser from the approved details.
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
Create Invoice
Tool to create a new invoice record in the organization. use after ensuring the customer exists in chaser.
Why this helps
Approved work can get stuck in chat while someone remembers to open Chaser and create the invoice.
- Reduce the gap between approval and billing.
- Keep the approval context close to the resulting invoice.
- Avoid retyping invoice details from a Slack thread.
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, then describe that it should create a Chaser invoice from a clear channel approval after confirming the customer exists.
- 3Pick Slack Channel Message Received as the trigger and choose a channel for run reports.
- 4Test with one real approved invoice example and review the Chaser result.
Questions about this workflow
Will every channel message create an invoice?
Describe in the prompt that Notis should act only on clear invoice approvals and use the specific details in that message or its context.
What if the customer is missing in Chaser?
The prompt should tell Notis to confirm the customer exists before creating an invoice, and to report when that prerequisite is not met.
