Abstract: Market participants including banks, vendors, and finance professionals are apparently having a difficult time achieving consensus about the vocabulary to use to describe changes in corporate accounts payable practices. Part of the confusion arises from the data interdependencies inherent in the "procure-to-pay" process, culminating in the three-way match in Accounts Payable. Buyers seeking solutions will have to dig for more detail to accurately understand the capabilities of any "e-payables" application.
