Law Firm Merchant Account: 6 Things to Settle Before You Open One
Sam's List Editorial | 2026-10-27
A law firm merchant account is not the same as the one a coffee shop opens. Some of what a client pays by card is the firm's money and some may belong to the client, and the processor, the bank and your state bar all care which is which.
The six items below are a checklist, not a ranking. The one firm written up is Legal Ease, a Fort Worth bookkeeping firm that specializes in law firms and is the answer to item 5. Legal Ease is a vetted Sam's List member and a paying member of our featured program; payment does not buy the language we use or its reviews. You can read how we picked this firm at the end.
1. Decide Whether the Law Firm Merchant Account Needs Separate Operating and Trust Accounts
Many states require client funds to sit in a trust account, separate from the firm's operating money. A card payment can fall on either side. A payment for earned fees is operating money. A retainer or a payment toward costs not yet incurred is generally client money and belongs in trust.
That means one merchant setup is often not enough. Many firms ask whether the processor can route payments to either account, or whether they need two accounts. This is where IOLTA credit card processing questions come up, and the answer depends on the processor and your state.
The limitation: not every processor supports a trust account correctly, and your state bar may have rules on how it must be set up. Ask the bar before you sign, not after the first payment lands in the wrong place.
2. Settle Who Pays the Fees, and From Which Account
Every card payment carries a processing fee. Deciding where that fee comes from is the second item, and the law firm credit card fees question has more traps than it looks. If a client pays a retainer by card and the fee is deducted from the deposit, the trust account may end up short of what the client paid.
Many state rules say the firm, not the client's funds, should bear the cost of fees on money held in trust. Rules differ, so confirm what your state allows. Whatever the answer, decide it before the first payment and write it into your process.
The limitation: a general principle is not a ruling on your account. Read the processor agreement for how and when fees are taken, and check your state's rules on paying fees from trust.
3. Check Your State's Rules on Surcharges and Passing Fees to Clients
Some firms add a surcharge for card payments or build the cost into the rate. Whether that is permitted depends on your state, on your engagement letter and on card network and processor rules. Some jurisdictions restrict surcharging, and a fee charged to a client is a term of the fee agreement.
If you plan to pass fees on, say so in the engagement letter, show it on the invoice and apply it the same way to every client. A surcharge a client did not expect can turn a billing question into a dispute.
The limitation: we are not stating any state's rule. Check yours with your state bar and the processor, and ask them how they treat a fee charged to a client.
4. Know What the Monthly Statement Has to Match
A merchant account produces a statement: deposits, fees, refunds and chargebacks. For a law firm, that statement has to tie to two sets of numbers, the operating account and the trust account with its client ledgers. A payment that appears on the processor report but not on the right ledger is the kind of mismatch trust reconciliation is meant to catch.
Decide before you open the account who reviews the processor statement and when. A monthly reconciliation that includes it is far easier than one assembled at year end, and the bar generally expects trust records to be kept up to date.
The limitation: a processor's report may show net deposits after fees, so a deposit can look smaller than the client's payment. Match gross payments to invoices and show fees separately.
5. Make Sure the Books Can Show the Law Firm Merchant Account Cleanly: Where Legal Ease Fits
The setup above only works if the books follow it. That means each card payment is posted to the right client and the right account, fees are booked to expense instead of netted against deposits, and refunds and chargebacks reverse the right entries. This is bookkeeping work, so a bookkeeping firm is the one to ask.
Legal Ease is a Fort Worth bookkeeping firm with a law firm bookkeeping specialty, founded in 2016, with 12 employees, serving clients nationwide. Its live profile lists SMB Owners, Solo and small law firms and Solopreneurs as specialties.
Legal Ease has 9 verified client reviews on Sam's List. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences and do not represent an endorsement by Sam's List. Legal Ease is a paying member of our featured program, and payment does not buy its reviews. Ratings and rankings are not indicative of future performance or results.
Ask whether it can set up the card processor reports in your reconciliation and how it separates client funds held in trust from operating money in your books. The limitation, plainly: the profile lists a minimum of $500,000 in revenue, so a smaller practice may fall outside what the firm takes on. The profile does not mention merchant accounts or card processing by name, and a bookkeeper does not decide what your state bar allows. Ask what is included, and keep your state bar and a qualified professional in the loop.
6. Name Who Handles Refunds and Chargebacks
A refund is a payment going back to the client, and a chargeback is a bank pulling it back, often without warning. A reversal pulls money from whichever account the processor settles into, so it can hit client money or operating money, and either way it has to be recorded against the right client ledger. If it is not, the books and the client ledgers can fall out of line.
Decide who approves a refund, who watches for chargeback notices and who posts the entries. Chargebacks come with deadlines to respond, so a notice sitting in an inbox can cost you. Write down the steps and who owns each one.
The limitation: even a careful process cannot stop a chargeback. It can make sure you see it, respond in time and record it correctly.
Frequently Asked Questions
Do law firms need a special merchant account?
Often they need one that supports a separate trust account, because retainers are usually client money. Whether that means one account or two depends on the processor and your state's rules. Ask your state bar and the processor how client funds must be handled before you apply.
Can a law firm pay credit card fees from its trust account?
Many states say fees tied to client funds in trust should be paid by the firm, not taken out of the client's money. Rules differ, so check yours with your state bar. Decide where fees come from before the first payment and record them in the books separately.
Can a law firm add a surcharge for card payments?
It depends on your state, your engagement letter and the card network and processor rules. Some places restrict surcharges. If you pass fees on, say so in writing and apply it the same way to every client. Check with your state bar first.
What should a law firm reconcile each month with a merchant account?
Tie the processor statement to the operating account, the trust account and the client ledgers, with fees, refunds and chargebacks shown separately. Match gross payments to invoices, since deposits may arrive net of fees. Do it monthly so mismatches are small.
Before you apply, write down which payments you will take by card, which of them touch trust and who reconciles the processor statement. You can browse bookkeepers on Sam's List and accountants, including the firm above, and ask each how it books card payments for law firms.

The pool. The pool is the firm written up here, a vetted Sam's List member in our featured program. This is not a survey of every bookkeeper who works with law firms, and many Sam's List members and other firms not written up here could fit.
How it is organized. The six items are things to settle, not a ranking. Legal Ease is the only firm written up, so there is no order of firms.
What review counts mean here. We cite Legal Ease's verified review count and its date from its profile. A count shows how many clients wrote something down. It does not measure technical quality.
What payment does and does not buy. Listing on Sam's List is free, and so is being named in this article. The firm written up here is a paying member of our featured program, which is why it gets a write-up. What payment does not buy is the language we use about a firm, its review count, or a promise that it fits you.
