Get invoices out the door and chase payment without manual effort. Many invoicing
automations are triggered from **projects** (raise an invoice when a project hits a status)
— this guide covers the invoice-specific trigger and action; see
[Projects & Tasks](05-projects-and-tasks-automations.md) for the project-driven billing
templates.
## Triggers
| Trigger | Type | Fires when |
|---|---|---|
| **Invoice Created** | Event | An invoice is created. |
| **Invoice Timer** | Timer (daily) | Runs daily over **unpaid** invoices (where payments are less than the total due). Used for payment reminders. |
## Conditions you can use
- **Total**, **amount paid / outstanding** — e.g. only chase invoices over a value, or
compare *Total paid* to *Total* to find unpaid ones.
- **Due date** — for "N days overdue" reminders via the timer trigger.
## Actions
**Send Invoice Email** — emails the invoice to the client.
- *To* / *CC* — recipients (Project Contact/Client/Manager, Invoice Client, or a typed
address). *To* is **required**.
- *Subject* and *Message* — **required**; supports invoice placeholders.
- *Document template* — optional; attaches a generated invoice PDF (including its
timesheets).
## How invoices get raised automatically
The actions that **create** invoices live on the project side, because that's where the
billing logic and amounts come from. Using *Project Status Updated* (or *Project Created*)
you can automatically:
- Raise a **deposit** invoice when a project starts.
- Raise a **progress** invoice at a milestone status.
- Raise the **final** invoice (remaining balance) on completion.
- Invoice **actual usage** (time, stock, billable purchases) on completion.
Each of these can either leave a **draft** for you to review, or — in the "create and send"
versions — be **approved** and **emailed** automatically. See the billing templates in
[Projects & Tasks](05-projects-and-tasks-automations.md#ready-made-templates).
## Building a payment reminder
There's no pre-built payment-reminder template yet, but you can build one:
*Invoice Timer* → condition **Due date is exactly 7 days old** (and 14, 21…) → **Send
Invoice Email** to the client. Each reminder fires once on its day.
## Tips
- Invoice automations respect your tax, markup and client credit-term settings.
- Production jobs are skipped by the project billing actions.
- Test approve-and-send billing with **Draft** first, then switch to **Approved** once
you're confident the amounts are right.
