Stop typing supplier invoices.
Invoices arrive however suppliers send them. Fintray reads every line, matches it to the order it bills against, works out the tax treatment and posts the result into your ERP, with the reasoning kept beside each record. Your team sees the exceptions, not the pile.
It keeps the systems you already run on, including your accountant's. Test it for a month alongside your current process, on your own invoices, with nothing switched off.
