Invoices, retainers, and trust accounts — priced right.
Law firms, agencies, consultants, accountants — professional services take payment in a small number of large tickets, often on corporate or commercial cards. Per-transaction cents don't matter much. Interchange category, card mix, and compliance do.

What professional services owners keep flagging.
Trust accounting is worth double-checking
How processing interacts with IOLTA requirements is worth confirming with your own compliance advisor — we can flag what we see, but it isn't legal guidance.
Large tickets amplify small percentage differences
A 0.3% markup difference matters far more in dollar terms on a $5,000 invoice than a $50 one.
ACH is underused
For recurring or large invoices, ACH is frequently cheaper than card processing and rarely offered by default — we check if it fits your client base.
What our review measures for professional services.
- Trust account considerationsFor law firms specifically, IOLTA and trust accounting rules can affect how processing fees are handled around client trust funds — a consideration worth verifying with your bar association or accountant.
- Commercial and corporate card ratesB2B and corporate cards often carry different (frequently higher) interchange than consumer cards; we confirm you're not overpaying by treating them the same.
- Invoicing and ACH optionsFor large tickets, ACH or invoicing can be meaningfully cheaper than card processing; we review whether that's offered and used where it makes sense.
- Retainer and recurring billingFor firms with ongoing retainers, how recurring charges are processed and reconciled.
- Card-not-present handlingMost professional-services payments happen by phone, email link, or online — reviewed for both cost and fraud exposure.
