Ok, so now that I have Quickbooks Online, I now see the ECS VAT codes as well as the RC.  Now I just want to confirm which code I should be using to account for RC purchases such as Google Adwords?  The main difference I see is that ECS 20% inputs into box 2 on the VAT return and RC into box 1. I have always used RC in the past, do I continue to use that?
