# Billing settings

> Your invoice numbering, terms and payment instructions.

**Billing** in the sidebar shows the amount owed, the amount overdue, and the payments received this month. The **Invoice details** section holds the settings every invoice uses. Click **Edit** to change them.

Billing

| Setting | What it does |
| - | - |
| **Number prefix** and **Next number** | Invoice numbers look like OE-0042. You cannot change them after you issue the first invoice. |
| **Default terms, days** | How many days a buyer has to pay. You can change it on each invoice. |
| **Payee name** and **Payee address** | Who the buyer pays |
| **Payment instructions** | Bank name, account name, routing number, account number, SWIFT |
| **Footer** | A tax registration or a closing note, at the bottom of every invoice |

> [!WARNING]
>
> Fill in **Payment instructions** before you send an invoice. Without them, the invoice does not say how to pay.
