The Vet Voucher (VV) cannot be added to the account until the order the voucher is to be applied to has been invoiced. You also have to wait for the voucher to be applied to the order before adding the payment. 


Sequence it should be processed in:
1. add membership order/renewal/product
2. invoice the newly created order
3. add Veteran Voucher
4. wait for the deduction to be applied to the invoice
5. add the payment to the invoice.

IF any of these steps are missed or out of order the (VV) will be applied late or it will be applied to the incorrect invoice. The voucher will always be applied to the last " invoice" that was made.


If you are adding multi (VV) to the same order do not keep adding VV to the account. Add it once and adjust the quantity in the invoice to account for how many are needed.
