I have identified a number of interesting topics to work on, for which I'd appreciate your input: how would you vote for, in order of priority, given the following titles? a> Transaction Banking for regional banks b> Strategies for Trade Finance c> Processes, People, and Technology in Transaction Banking d> Status of electronic invoicing e> Demistifying TSU f> Procurement and Finance: the two sides of the working capital optimization equation g> Cash advisory services from banks h> State-sponsored supply chain finance programs i> The ROI of interoperability Happyo to provide more information/ clarification where needed.
