# The client interface

The client interface is ****a secure web page**** between you and your clients. Only your client can access it to view the documents you provide (contracts to sign, quotes, invoices, questionnaires, etc.).

![Client interface](https://storage.crisp.chat/users/helpdesk/website/-/5/7/1/1/5711a8e7e1a7100/32c0e7b6-5de2-4a50-8a72-98eae1_1owy8zf.png)

To give the most professional appearance possible, it is strongly recommended to ****personalize this interface**** by adding your logo and your color.

You can add your logo and choose your primary color in [My account > My activity](https://www.fotostudio.io/app/companies/2118/edit).

Access to the client interface is done via specific links. For example, when you send an invoice to your client from Fotostudio, a secure link is included in the email. When the client clicks on this link, they are automatically taken to the client interface, to the sent invoice.
