Accepting card payments as a mediator: what you actually need.

If your fee is split between two parties, how you accept payment matters more than it does for a single-client practice. A card payment lets each party settle their share in about a minute, from a phone, from anywhere. A check means waiting on two mailboxes, two signatures, and two trips to the bank. This article covers what a solo mediator actually needs to accept cards, what you can safely ignore, and the honest math on fees.

Why card acceptance matters for split fees

Industry benchmarks report that most legal clients now prefer paying by card, and the same holds for the parties in a mediation. When a fee is split, that preference compounds. You are not waiting on one payment, you are waiting on two, and the two parties rarely move at the same speed.

With cards, each party can pay their share the moment they decide to, without coordinating with the other side. With checks, you are chasing two separate mailboxes, and one slow party holds up your entire fee. For a split fee, fast and independent payment is not a convenience. It is the difference between getting paid this week and getting paid next month.

What a solo mediator actually needs

The list is shorter than the payments industry likes to suggest. To accept cards for professional fees, you need:

That is the whole list. A modern processor such as Stripe covers the first item with no salesperson, no application interview, and no monthly minimum on entry tiers. The rest is about how payment is requested and recorded.

What you do not need

A lot of what gets sold to professionals is aimed at businesses that are not you.

You do not need a merchant account salesperson. The old model, where a representative signs you up for a merchant account with a tiered rate sheet, has been replaced for most solo practices by flat-rate processors you can set up yourself.

You do not need terminal hardware. You are not swiping cards across a desk. Your parties are paying remotely, so a card reader or point-of-sale terminal is equipment you would never plug in.

And if you are a non-attorney neutral, you do not need a law-firm-specific payment product. Those tools are built around attorney trust accounting and IOLTA compliance. They are excellent for law firms handling client funds. If your practice collects earned professional fees and does not hold client money in trust, that machinery is solving a problem you do not have.

The fee reality, stated plainly

Card processing is not free, and it is worth knowing the real number rather than a vague sense that cards are expensive.

Standard card rates through Stripe run about 2.9% plus 30 cents per transaction. On a $1,500 share, that is roughly $44. On a full $3,000 fee split between two parties, you would pay that on each share, so about $88 total.

Weigh that against the alternative honestly. The cost of a check is not zero. It is the time you spend requesting it, the follow-up when it does not arrive, the delay in your cash flow, and the occasional payment that never comes at all. For many mediators, roughly $44 to have a party's share land in the account the same day they agree to pay is a straightforward trade. For others, it is worth passing a processing fee along or reserving cards for the parties who ask. Either way, the number is small and knowable, not a mystery.

The trust-account caution that keeps this simple

There is one rule that matters more than any other, and it is why card processing for mediators is usually simpler than for law firms.

Card processing fees must never touch client trust funds. Trust or IOLTA money belongs to clients, and a processor's fee cannot be deducted from it. This is exactly the kind of compliance problem that makes payments complicated for attorneys who hold funds in trust.

Mediation fees are different. They are earned professional fees for your service, your money once the work is done. Because they are not client funds sitting in trust, a plain processor depositing into your business account is entirely appropriate. You are charging for a service you performed, the same as any professional. The simplicity is not a shortcut. It follows directly from the fact that you are not holding anyone else's money.

The split-fee wrinkle generic processors miss

Here is where a plain processor stops short. A standard payment request assumes one payer and one amount. It can send a $3,000 request beautifully. It has no concept of two parties who each owe half, no way to give each party a link scoped to their own share, and no live view of which party has paid.

So you improvise. You send two requests and hope neither party pays the wrong amount. You watch your deposits and match each one to a party by hand. You track partial payments in a note. The processor charges the card correctly, but the split is your job again.

FlowPay is built for exactly this wrinkle. It gives each party their own Stripe-hosted payment link for their share of one invoice, with fixed or flexible splits, fresh links generated automatically when someone pays only part of their share, a live status for each party, and a receipt for every payment. The money settles directly into your own Stripe account and is never held by us, and because you are collecting earned professional fees rather than trust funds, it stays clear of IOLTA entirely. The Solo tier is free, with a 2% fee per collected invoice.
