It's all about ease of use, short setup cycle and 100% vendor approval without waiting on a network to process documentation.
There are many trade payable finance companies in the market to choose from. The reality is buyers need an easy process to apply, easy method to approve vendors, and a fast and flexible system for the internal staff to learn the process. If the system is too difficult for the accounts payable department to track and pay suppliers with additional work and multiple processes, it will fail. If the system requires a 50+ page document for the suppliers to sign up for the program, it will fail. The main focus is to maintain very few steps for the supplier to submit an invoice and the payables department to approve, authorize to pay and track.
