Keep invoice details aligned with delivery changes
If a delivery change affects an invoice detail, have Notis update the existing Firmao invoice so billing records do not lag behind the work.
Trigger
Issue Updated Trigger
Triggered when an issue is updated. For example labels are changed, issue status is changed, etc.
Action
Update Invoice
Tool to update an invoice. Use when you need to modify an existing invoice by its ID after retrieving its details.
Why this helps
Changes to delivery can leave invoice details inaccurate when no one remembers to carry the update into billing.
- Reduce billing discrepancies caused by out-of-date delivery context.
- Connect an issue change to its related invoice.
- Avoid manually repeating a clearly specified invoice update.
Setup
Build it in a few focused steps.
- 1Connect Linear and Firmao to Notis once through the portal.
- 2Create an automation and describe which issue changes affect which invoice details and how to find the invoice.
- 3Select the Linear Issue Updated trigger and choose a channel for run reports.
- 4Test with a real change and an invoice that is safe to update, then check the result.
