We were informed that it was common and no trouble for you to accept a dataset and handle the import into your system.

Upon pulling that dataset and waiting on several multi-day delays we were told that, oh, you don't do that in our case and that most clients just did it themselves over an API. Which we then did internally as a last minute item on a very tight, very big deadline. Just the sort of thing that's fun to do with client credit card data.

Past that I'm not interested in giving out any more info about my company.

EDIT: Wow. Sure am glad that I bothered to type up an honest answer.
