You really don't have to even run a report. It is simple, you pay 2.6% + $0.10 for every swiped, NFC, or dipped card. That's all you need to tell them (which they should know and not even be asking if they are a knowledgeable Salesman).
Just watch out for all the hidden fees like, PCI compliance fees, monthly fees, reward card fees, monthly minimum fees, per swipe fees, AMEX or Discover fees, daily closing fees etc. That's the stuff they don't want you to see when they come saying we're only @2.15% or 1.95%. Sometimes those reward card fees can be 2.5% by themselves. And don't forget about american express being the same price as visa and mastercards and discover at square. All those small things add up to lots. And simple is so much less headache to and that alone is worth money.
Just run the default report and it gives you all you need to know.
