Payment Processing That Keeps Your Trust Account and Your Fees Separate

Law firms face payment processing challenges that no other industry deals with. The most critical is IOLTA (Interest on Lawyers' Trust Accounts) compliance. Every state bar association has strict rules about separating client trust funds from operating funds. When a client pays a retainer, that money must go into a trust account — not your operating account. When you earn fees, those must be moved to your operating account.

Most payment processors have no concept of this separation. They deposit everything into one account and leave you to sort it out manually. This creates compliance risk, audit headaches, and potential ethics violations that could jeopardize your license to practice.

At Payment USA, we configure separate deposit routing for trust and operating accounts. When a client pays a retainer via credit card, it routes to your trust account. When they pay an invoice for earned fees, it routes to your operating account. No manual reconciliation. No compliance gaps.

The Economics of Credit Card Processing for Law Firms

Law firms process some of the highest-value individual transactions of any service industry. A personal injury retainer might be $5,000. A corporate matter could involve a $25,000 initial payment. A real estate closing might process $50,000 or more through credit cards.

On flat-rate pricing at 2.9% + $0.30, a $25,000 corporate retainer costs $725.30 in processing fees. On interchange-plus with a 0.20% markup, that same transaction costs approximately $430 — a savings of nearly $300 on a single transaction. For firms processing $200,000+ per month in client payments, the annual savings can exceed $15,000.

Surcharging: How Law Firms Can Eliminate Processing Costs Entirely

Surcharging — adding the processing fee to the client's bill when they pay by credit card — is legal in 48 states and is increasingly common in legal services. Many law firms now add a 3% to 3.5% surcharge on credit card payments while offering ACH or check payments at no additional cost.

Clients overwhelmingly accept surcharges on legal payments because (a) the payment amounts are large enough that convenience outweighs the fee, and (b) it's become standard practice in professional services. For firms that implement surcharging, processing costs drop to effectively zero.

We handle the surcharging setup, compliance disclosures, and receipt formatting. The surcharge is automatically calculated and clearly disclosed to the client at the point of payment, meeting all card brand requirements.

Recurring Billing for Retainers and Payment Plans

Many law firms — particularly those in family law, immigration, and criminal defense — offer monthly payment plans for their fees. Without automated recurring billing, your staff is chasing payments manually, making phone calls, and dealing with failed collections.

Our recurring billing system lets you set up automatic monthly charges on the client's card. Account updater technology automatically updates expired or replaced card numbers, reducing failed payments by up to 40%. Clients receive email receipts automatically, and you can see all upcoming and past charges in a simple dashboard.
