They're essentially offering a free open source platform to accept web-based ACH payments with their own secure gateway. I think you will need to obtain your own ACH processing service through a bank, but even with that, it seems a lot more attractive than Balanced's ACH debit option (1% + $0.30 per transaction). The problem is I don't see anything online that's written about it and their website looks a little amateur.

(I work for Balanced)<p>Hi Saitoyeung,<p>Balanced caps its transaction fee at $20.00 - Is that an issue for you? Email me - mahmoud@balancedpayments.com<p>Also, this is a direct quote from OpenACH:<p>> To get started with OpenACH, U.S. Bank customers can simply request the bank's ACH Direct Transmission service, along with an optional SinglePoint account management portal. Once your account is ready for testing, use the U.S. Bank plugin within OpenACH to transfer your files and handle returns/changes.
