Keep Slack purchase order decisions attached to the right Coupa PO
Give future-you one place to check why a purchase order changed or moved forward.
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
Add Comment to Purchase Order
Tool to add a comment to a purchase order. Use when you need to add notes, feedback, or mention users on an existing purchase order.
Why this helps
Important procurement context gets buried in busy channels, leaving founders to reconstruct decisions later.
- Preserves decision context beside the relevant PO
- Reduces searching across channels when questions return
- Creates a consistent place for teammates to review rationale
Setup
Build it in a few focused steps.
- 1Connect Slack and Coupa to Notis once through the portal.
- 2Create an automation in the portal and describe adding relevant PO decisions from Slack to the matching Coupa purchase order as a comment.
- 3Select the Slack channel message trigger and choose a channel for run reports.
- 4Test with a real message that clearly identifies an existing PO and its decision.
Questions about this workflow
Will every channel message become a PO comment?
Tell Notis in the prompt to act only on messages that clearly discuss a Coupa purchase order and contain a useful decision or update.
What if the PO cannot be identified?
Have the instruction skip the comment when the PO match is uncertain and report the run for follow-up.
