Many thanks for the detailed explanation, greatly appreciated, however let me step through my query.
I am a uk user
I have quickbooks online essentials, not plus. So the answer is I can't utilise the billable expense, correct?
I do not have access to quickbooks desktop, I've tried to download the software but get prompted for a licence key that I can't find anywhere- the F2 button does not retrieve it. Is desktop available without additional fees to online essentials users?
