Invoice completed milestones without losing the handoff
When a channel update confirms that a billable milestone is complete, Notis can carry the supplied details into Chaser and create the invoice for an existing customer.
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
Completed client work can move on to the next project before anyone remembers to bill for the milestone.
- Shorten the time between completed work and invoicing.
- Keep milestone context with the billing handoff.
- Require an existing customer and sufficient invoice details.
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, instructing it to create a Chaser invoice only when a channel message confirms a billable milestone and the customer exists.
- 3Pick Slack Channel Message Received as the trigger and choose a channel for run reports.
- 4Test with one real completed milestone and inspect the invoice in Chaser.
Questions about this workflow
Will every project completion post be billed?
Describe which milestone wording or confirmation counts as billable so Notis does not treat general progress as an invoice request.
What if the customer does not exist?
Have Notis report the missing customer prerequisite rather than create an invoice against an uncertain record.
