lets say i have 5 clients to which i'm providing my voice assistant service . should i create 5 different orgs or can i create 5 different accounts . will i get 1000 free minutes per org or is it per account only ?

The 1,000 free minutes are given per org, so to give each of your 5 clients their own free quota, you should create 5 separate org rather than managing them under one.

great thanks
