Hi, I am starting to use the prepayment invoice functionality for sales order.

The prepayment invoice is posting correctly with the VAT shown as I require 100% prepayment before the order is shipped.

One the payment is received and I ship and invoice the order, the VAT breakdown on the sales invoice shows as an in and out netted off. 

I need the final sales invoice to show the VAT as this is an official tax invoice for the customer to post.

Can anyone advise how you get around this?

I have not set up any special VAT bus or product posting groups for the prepayment process.
