Reselling Unifi Talk

i have a small computer shop and have installed Unifi in many locations and manage those locations… I have a few clients looking for phone service. i would like to be able to resell them the unify talk, is this possible? how would that work in porting their numbers? I do not want to own their number…

You would sale them the hardware, and do the installation.

The Unifi Talk subscription plan , or sip provider would be in the name of the client, you would migrate existing numbers to the new line provider,
