Invoices

Hi All,

Been using QB for awhile now and just wanted to clarify something.

In my line of work (telecom) we only collect the HST upfront on a lot of our hardware. 

Customer A gets a phone on a plan, as per our telecom company we need to collect just the HST of the device and the rest goes on the customers phone plan.

Iv been creating invoices with only the HST upfront and for tax I select "E" because i don't want to charge tax on tax. Is this the proper way of doing it?

Thank you so much.
