# Setting the default payment device (desktop)

The default billing device is the device that Zoyya uses to bill you on the computer you're working on. Before opening the cash register and issuing a bill, it is necessary to select the correct default payment device.

This article is about the affiliate Zoyya web app on PC.

## When to use this option?

Setting the default payment device is used when:

1. the user prepares the cash register on the computer for the first time,
2. after creating a new device you should start working on it,
3. the computer should issue invoices from another billing point,
4. default device is not selected,
5. the application displays the warning **Default payment device is missing**.

The default device is not changed to change the name, deposit, printer or payment type. These settings are edited on the existing device according to the article [Changing the billing device and impact on account numbers (computer)](https://help.zoyya.com/en/article/changing-the-payment-device-and-its-effect-on-invoice-numbers-desktop-scn2qc/).
