Update Chaser invoices after estimate changes
Connect approved scope changes to the invoice record before billing drifts out of date.
Trigger
Task Time Estimate Updated
Triggers when a task's time estimate is set, changed, or cleared. `changes[]` carries `TimeEstimateChange` entries only; `before` and `after` are millisecond strings or `null`.
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
Updated estimates can change billable scope while the invoice still reflects the old expectation.
- Keep approved scope visible
- Reduce billing discrepancies
- Make estimate changes reviewable
Setup
Build it in a few focused steps.
- 1Connect ClickUp and Chaser in Notis once.
- 2Create an automation telling Notis to update the related invoice only when an estimate change is explicitly approved for billing.
- 3Pick the ClickUp Task Time Estimate Updated trigger.
- 4Choose a report channel and test with one invoice-linked task.
Questions about this workflow
Does a time estimate equal an invoice amount?
No. Tell Notis how to interpret the approved estimate or use it to request review before updating.
What if the estimate is cleared?
Tell Notis whether to flag the invoice for review or apply a defined correction.
