The **Settings** page has the company and invoicing details of your Partner. Zimple shows these details on the
invoices that it sends to you.

## Update the company and invoicing details

1. In the sidebar, click **Settings**. The **Settings** page opens.
2. In the **Company** section, change **Company name**.
3. In the **Invoicing** section, change **E-invoice address**, **E-invoice operator**, **Invoicing email** or
   **Business ID**.
4. Click **Save changes**. The window **Confirm changes** opens and shows the old and the new value of each field.
5. Click **Save changes**. The Partner Portal shows **Partner updated.**

The bar at the bottom of the page shows the number of unsaved changes. **Save changes** is available only when
there is a change.

To close the window **Confirm changes** without a save, click **Cancel**. Your changes stay in the fields.

## Rules of the fields

- **Company name** cannot be empty.
- **Invoicing email** must be a valid email address.
- To remove the value of an invoicing field, make the field empty and save.

The browser does not let you save an empty **Company name** or an **Invoicing email** that is not an email address.
If a value breaks another rule, for example a value that is too long, the Partner Portal shows
**Update failed: Request failed (400)**. See [Settings fields](/docs/partner-portal/reference/settings-fields) for each
field and its rules.
