Here is my ideal usecase.

I could install your plugin on a website* that belongs to me.

* this website serves as a localhost or a main portal

From there I would like to manage my 2 or 3 businesses.

Are branding independant from the installation website?

Could I select from the 2 or 3 branding from your portal and assign to the estimate or invoice?

I never email estimates or invoices directly from the portal.

Is my usecase possible with your plugin?

Thanks.
