@Lior Bar I have a similar situation with VAT, but I need to be able to track it on it’s own account so I can get a refund for export. I use a markup item to track that and have a simple custom workflow to check that VAT is included on PO’s when they are from vendors located in the appropriate locations. You could do that to check tolerance. depending on how many accounts you have you could just have different markup items for the accounts or you could probably do a custom workflow to change the account based on the PO item

@rangersanders I might go with a custom solution eventually, i was trying to look for NS process that is already built in, thanks for the detailed answer!
