What about U.S.-based companies paying U.S.-based freelancers?

Our company has fewer than 20 freelancers, and I'm trying to figure out whether Payoneer is right for us. We have a few freelancers outside of the U.S., but the rest of them are in the U.S.

After looking around the Payoneer website, I'm still confused. What would be the simplest (and cheapest) way to use Payoneer to pay our U.S.-based freelancers? I saw something about ACH transfers to local receiving accounts that would be linked to Payoneer accounts so that fees could be reduced, but that sounds more like a process for international transactions. Am I wrong? Would this also be the process for U.S. to U.S. payments? What am I missing?

It would also be great to know what the actual fees would be for using Payoneer to pay our freelancers. I'm seeing a lot of mentions of "free" this and that, but surely, we'd have to pay somebody something. The payment funds would be coming directly from our company's bank account.

Thanks in advance for your help!
