# Invoicing defaults

> Every setting under Settings → Invoicing and what it controls downstream.

**Settings → Invoicing** sets the defaults every new invoice starts from: when invoices are generated, when they're due, how they look, and whether Harness chases them. One **Save** button applies the page.

## Billing cadence

Picks when Harness generates invoices automatically (Professional plan; see [Run your monthly billing](/guides/run-your-monthly-billing) for the full cycle):

| Cadence                | What happens                                                                                            |
| ---------------------- | ------------------------------------------------------------------------------------------------------- |
| **Per Lesson**         | Each attended lesson gets its own draft invoice immediately.                                            |
| **End of Month**       | On the 1st, drafts collect the previous month's unbilled charges.                                       |
| **Beginning of Month** | On the 1st, the coming month's lessons and charges are created from your schedule and drafted up front. |

## Payment defaults

| Setting                          | What it controls                                                                                                                                             |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Lesson terms**                 | The due date on new invoices: Due on receipt, Net 7, Net 30 (the default), or Net 60.                                                                        |
| **Default payment instructions** | Text copied onto every new invoice's "how to pay" section: your Venmo handle, check instructions, whatever you tell people.                                  |
| **Credit application**           | **Automatic** applies an account's available credit when an invoice is sent; **Manual** waits for you to apply it yourself. See [Credits](/billing/credits). |

## Automatic reminders

The **Send automatic reminders** switch, and one toggle each for **3 days before due date**, **On due date**, and **3 days after due date**. These set the defaults for new invoices; you can override them per invoice in the builder. The full behavior lives at [Invoice reminders](/billing/invoice-reminders).

## Invoice header display

Five toggles control what prints at the top of your invoices (email and PDF), with a live preview beside them:

| Toggle             | Notes                                                                               |
| ------------------ | ----------------------------------------------------------------------------------- |
| **Studio Name**    | Always on.                                                                          |
| **Studio Address** | Available once an address is set in [Studio details](/settings/profile-and-studio). |
| **Phone Number**   | Available once your profile has a phone number.                                     |
| **Email**          | Your contact email.                                                                 |
| **Website**        | Available once your studio website is set.                                          |
