Hopefully this will make sense:
Our company is trying to figure out how to code, or whatever, our Supplier BP invoices to show that we were not taxed and should have been so we can run a report to decided what we owe for sales tax.
OR if we can somehow code the invoices to be marked as we didnt get charged tax so they show up in a report and we then decipher on our own from that list what we should have paid tax on.
