# Edit customer details and notes

Update a customer's name, logo, address, or internal notes.

### Steps

1. On the customer's page, click **Edit**.
2. To change the logo, click or drag a new image into the logo area, or click the small X to remove it. Signal accepts PNG, JPEG, GIF, SVG, or WebP files up to 2MB.
3. Update the **Company Name** if needed. This field is required.
4. Update the **Address** fields: Street, City, State, Postal Code, and Country.
5. Update the **Customer Notes** text. Clearing this field removes the customer's notes.
6. Click **Save Changes**. The button reads **Saving...** while it saves.

### What you see

The customer's page updates with your changes. Notes appear in the **Notes** section at the top of the page, only when there is text to show.

### Notes

* Unlike the New Customer form, address changes made here are saved.
* If you do not have permission to edit the customer, Signal shows **"You do not have permission to edit this customer. Please ask an organization owner or admin."**
* Setting an account owner is on this same form; see Assign an account owner.
