# How do I enable or disable the auto-generation of invoice number?

To enable or disable the auto-generation of invoice number:

*   Go to the **Invoices** module on the left sidebar, and click the **\+ New** button in the top-right corner.
*   In this page, go to the field _Invoice #_, and click the **Gear** icon right next to it.
*   In the _Configure Invoice Number Preferences_ pop-up that appears, choose the option **Auto-generate invoice number** if you would like to enable the auto-generation of invoice number.

**Insight:** You can also customize the **Prefix** and the **Next Number** fields as you prefer.

*   Select **Enter invoice numbers manually** if you would like to disable the auto-generation of invoice number.
*   Once you’ve made the changes, click **Save**.

Enabling or disabling the auto-generation of invoice number can also be perfomed on existing invoices by editing them. For imported invoices, this action can be done before the upload.
