Thick bill verticals
If there is one certainty, paper invoices will be there for the coming years… or not? Implementing self-billing could be a valid option, where you as a buyer are in the driving seat.
Based on your procurement information, an invoice advise is presented to your vendor. The vendor approves and creates the electronic invoice. If the vendor disagrees, he will dispute upfront the proposed transaction avoiding costly invoice exception handling.
It is you the buyer who decides what data a vendor can modify, an invoice created this way is guaranteed exception free. Electronic invoices without hassles from small vendors: yes it is possible!
