Why this helps
Department setup often gets separated from the discussion that established the need for it.
- Keep approved organization changes moving.
- Reduce repeated coordination around a settled decision.
- Preserve a clear connection between discussion and setup.
Setup
Build it in a few focused steps.
- 1Connect Slack and Brex to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis in conversation.
- 3In one plain-language instruction, ask Notis to create a Brex department only after Slack confirms it is approved.
- 4Select the Slack channel message trigger and choose a report channel.
- 5Test with one real approved department decision.
