Creating a personalized booking inquiry form that includes a client's logo is not currently possible with Tern's standard form customization options. The branding on forms is tied to the branding settings in your Tern account, and you cannot customize individual form branding to include different logos for each form. However, you can add photos to your forms, which could include your client's logo, by uploading a picture into the form description or an info block of the form as a workaround for personalization.
