What rates will my group pay for credit-card processing if we use SchoolAuction.net
I can't tell you! That's because we don't tell you which bank you have to use for credit-card processing. We're compatible with a huge range of full-service merchant-account providers, through our integrations with a number of payment gateways, including Authorize.net, Vantiv/Element, Network Merchants, Inc. and a few others. You can shop around for an account with rates you like.
We also have an integration with WePay - if you choose that option, you can be up and running in 5 minutes, and you won't pay any monthly fees - only a swipe rate of 3.25% + $0.30/transaction.
