Some money should never move on a card. A recurring invoice, a monthly retainer, a large equipment order, a lease payment: those are predictable, agreed in advance, and paid by a customer you already know. Running them on credit costs you a percentage of the whole amount, every month, forever. Black Mesa Payments sets businesses up to take that money by ACH instead. We are based in Tulsa, our reps work in the markets they cover, and our inside sales team handles clients nationwide.

What ACH is, in plain terms

ACH is a bank-to-bank transfer. Your customer authorizes a debit from their checking account and the funds move over the automated clearing house network instead of the card rails. No card brand sits in the middle, so ACH is not priced off interchange and it does not carry the card brand dues and assessments that ride along with a card transaction. The published QuickBooks rates make the gap concrete: Intuit charges 2.99% on an invoice paid by card and 1% on the same invoice paid by ACH.

The payments that belong on ACH

  • Recurring invoices billed on terms to accounts you already know
  • Large-ticket B2B orders, where a percentage of the ticket is real money
  • Retainers and monthly engagements at professional practices
  • Rent, lease and equipment payments
  • Dues and membership billing
  • Standing orders from wholesale and distribution accounts

The pattern is the same in every case. The amount is known ahead of time, the payer is an established account, and nobody is standing at a counter waiting on an approval.

Where cards still win

We are not going to tell you to move everything to ACH. Cards are better any time the decision has to happen on the spot: a first-time customer, a walk-in sale, a deposit taken at a kitchen table, a checkout on your website. ACH needs an authorization on file and a bank account the customer is willing to share, which is an easy ask from an account you invoice every month and a hard one from a stranger. Most of the businesses we work with run both. The real work is deciding which payments go on which line.

ACH inside QuickBooks

If you invoice out of QuickBooks Online you are already paying for ACH, probably without thinking about it. Intuit's built-in processing runs 2.99% on invoices, 3.50% on keyed and other card-not-present transactions, and 1% on ACH. Our Hyfin integration replaces that processing layer and leaves QuickBooks exactly where it is. The merchant-paid ACH rate on Hyfin's published dual pricing program is 0.75%, and the sync runs both ways, so a paid invoice closes itself instead of waiting on a bookkeeper. One real limit: the two-way sync is QuickBooks Online only, not Desktop. Full detail on the QuickBooks and Hyfin integration.

Dual pricing puts ACH on the cheaper line

Dual pricing shows your customer two prices, one for credit and one for ACH. It is 100% compliant and it does two useful things at once. Your cost to accept a card can go to 0%, and the accounts that are happy to pay by bank transfer get a visible reason to do it. Across a book of recurring invoices, moving even part of that mix onto the cheaper line changes the annual number. Our average clients save between 15% and 100% a month on processing fees.

Run it against your own mix

Our savings calculator has an ACH share input for exactly this reason. Set it to how much of your revenue already arrives by bank transfer and it will show the same volume priced on your current processor against a dual pricing program. It is an estimate, not a quote. A statement is what turns it into real math.

Getting ACH turned on

Send us a recent statement and we will show you what you pay now, what would move to ACH, and what the difference looks like over a year. A typical merchant is boarded and live in 3 to 5 business days. Your processor fee program is locked in for the life of our relationship, and nearly all of our merchants are month to month. Card brand interchange, dues and assessments are set by the card brands and sit outside anyone's control, ours included, and we tell you that up front rather than after the fact.
