A potential client is interested in leaving their current gateway for Payflow. But they do a lot of bulk transaction processing, and their current gateway has a nice little windows app for processing a bunch of transactions specified in a csv file. Is there anything like that available for Payflow? A web based app or anything, I don't care. I'm tasked with estimating the effort to build something like that using the Payflow SDK directly, and I can do it, but I feel like I must be treading ground covered thousands of times before.
Thanks!
Phil
