# 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.).

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.
