You need a money transmitter license, or a licensed principal to operate under, if your business accepts money from one party and delivers it to another, and no exemption covers your specific flow. That is the whole test. It does not matter whether the parties are consumers or businesses, whether the money moves by ACH, card, wire or stablecoin, whether you hold it for an hour or a week, or whether you think of yourself as a software company. Federal law under the Bank Secrecy Act and the money transmission statutes of 49 states all start from the same definition, and the exemptions are narrower than the definition.
Most founders who ask the question are already doing the activity. The table below gives the usual answer for the common flows, and the sections after it explain the reasoning for each, the exemption that might apply, and the structural details that make it apply or not. The short version: receivables collection with assignment, payouts to third parties, payroll funded through your account, escrow, marketplace settlement and stablecoin transfers for others almost always need a license or a principal. Pure agent-of-the-payee collection and pure software with no custody of funds usually do not. Everything in between depends on the contract and on who controls the money while it rests.
General information, not legal advice. The facts of your contracts and your flow of funds decide the answer, and state law varies. Have licensing counsel confirm before you rely on any row above.
The definition everything starts from
Under the Bank Secrecy Act regulations, a money transmitter is a person that provides money transmission services, meaning the acceptance of currency, funds or other value that substitutes for currency from one person, and the transmission of that value to another location or person by any means. The definition in 31 CFR 1010.100(ff)(5) is deliberately broad, and FinCEN has said repeatedly that the label a business gives itself does not matter. What matters is whether funds pass through your hands on the way from one party to another.
A money transmitter is a money services business, which means registering with FinCEN, maintaining an anti-money-laundering program, keeping records and filing suspicious activity reports. Separately, 49 states require a money transmitter license to do the same activity, each with its own application, surety bond, net worth minimum and examination. Our licensing cost guide puts the 50-state total at roughly $250,000 to $435,000 upfront and 12 to 24 months.
The exemptions, federal and state, are exceptions to that definition. The two that matter most for business payment models are the federal payment processor exemption and the state agent of the payee exemption, and both have conditions that a lot of real-world structures fail. We cover the second in depth in our agent of the payee explainer.
Receivables and billing outsourcing
An outsourced billing or receivables firm invoices on behalf of client businesses, collects what customers pay, and forwards the proceeds. Whether that needs a license depends almost entirely on structure.
If you collect in the client's name, under a written agreement that makes payment to you satisfy the customer's debt, into an account the client controls, and invoice your fee separately, you are very likely an agent of the payee and exempt in most states.
If you take assignment of the receivable, send customers a notice telling them to pay you or an entity you own, collect into that entity's account, and forward 98 percent while keeping 2 percent, you have stepped outside the exemption at every point. You own the receivable, you control the funds, you net your fee from the stream. That is money transmission, and the fact that you extend no credit and charge no interest, which keeps you out of factoring and lending law, does nothing for money transmission law.
Payouts and disbursements
Platforms that pay contractors, gig workers, vendors, insurance claimants or affiliates on a client's instruction are the clearest case. The client sends you money; you send it to people the client owes. The agent of the payee exemption does not apply, because you are not collecting for the recipient, you are transmitting the client's funds to a third party. Some payout platforms avoid licensing by never touching the money, instructing a bank or a licensed processor to move it directly from the client's account to the recipient. The moment the funds rest in an account you control, the analysis changes.
Marketplaces
A marketplace that holds buyer payments and settles to sellers is transmitting the buyer's money to the seller. Many marketplaces rely on an agent of the payee position for the seller side, with terms that say payment to the marketplace satisfies the buyer's obligation to the seller. That works when the marketplace is transparent to the money: the seller is the payee, settlement is prompt, and the marketplace does not hold or use the funds. It stops working when the marketplace delays settlement to earn float, refunds or redirects funds at its own discretion, or pays parties who were not the payee. Most large marketplaces either hold licenses or run on a licensed payment facilitator for this reason.
Payroll, escrow and holdbacks
Payroll processors that receive an employer's funds and pay employees are transmitting money. Several states exempt payroll processors explicitly; others license them; the federal position is that a payroll processor can be exempt only in narrow circumstances. If payroll is a feature of a broader platform, assume licensing applies until counsel says otherwise.
Escrow is a licensed activity in its own right in many states, with its own statutes separate from money transmission. A holdback or milestone-release service that holds funds between parties is either an escrow agent or a money transmitter, and in some states both. There is no software exemption for holding other people's money pending a condition.
Software that never touches the money
The clean way to avoid all of this is to be software. If your platform instructs a bank, a licensed processor or a licensed payment facilitator to move funds directly between the payer and the payee, and you never have the ability to receive, hold, direct or control those funds, you are generally not a money transmitter. The test is control, not branding: an API that lets you redirect a payment to a different account is control. Many fintechs that believe they are software fail this test the first time an engineer adds a feature that lets the platform hold a balance.
Stablecoin and cross-border payments for others
Moving value for third parties on a blockchain is money transmission. FinCEN's 2019 guidance on convertible virtual currency applied the existing definition to businesses that accept and transmit virtual currency, and dollar-backed stablecoins fall squarely inside it. The GENIUS Act of July 2025 regulates who may issue a payment stablecoin and how it must be backed; it does not exempt anyone who transmits one. State money transmission statutes increasingly define monetary value to include virtual currency, so the state answer is the same. A business that takes a client's dollars, converts to a stablecoin, sends it abroad and pays out local currency is a money transmitter at both ends, as our guide to stablecoin remittance regulation explains, and it also needs on-chain address screening that a traditional transmitter does not.
What happens if you are already operating
Unlicensed money transmission is a federal offence under 18 U.S.C. 1960 and a state offence in nearly every state. In practice the question usually arrives from a bank's compliance team, a state regulator, a prospect's procurement questionnaire or your own counsel, and the cases that end in enforcement are the ones that kept going after it was raised. The right response is to stop treating the flow as settled and scope it properly, quickly, with a view to one of two routes.
The two routes, and which one fits a B2B flow
Your own licenses. Register with FinCEN, then apply in each state you serve. Expect 12 to 24 months, a quarter of a million dollars or more, surety bonds and net worth requirements, and a compliance function you build from scratch. You generally cannot continue the activity while applications are pending.
Operate under a licensed principal. Under 31 CFR 1022.380(a)(3), a business that is a money services business solely because it acts as the agent of another money services business does not register separately. The principal holds the licenses and the regulatory relationships; you operate under them as an authorized delegate, on a platform that provides the compliance program, the KYB and KYC checks, sanctions screening and the collection and payout rails. The timeline is weeks. The condition is that the principal's licenses can cover your flow of funds, which is confirmed in a scoping review before anyone commits.
For a consumer remittance counter the second route is well established, and our authorized delegate versus own license comparison covers it. For a business payment flow it is newer, because most principals were built for consumer remittance and cannot sponsor a receivables or payout model. Platly's licensing structure is built for business flows, and we adapt the platform around the model rather than asking the model to fit the platform. The fintech licensing page describes who it is for, and a 30-minute scoping call gives a straight answer on whether a specific flow fits, including when it does not.
Frequently asked questions
We are a B2B company. Does money transmission law still apply?
Yes. The definition does not distinguish between consumer and business parties. Several exemptions are easier to meet in a business context, such as the agent of the payee, but the starting presumption is the same.
We use a licensed payment processor. Are we covered by their license?
Only if the processor's license covers your activity and your contract with them makes you their agent for it. Using a processor to move money does not make you exempt if funds still rest in an account you control, or if you direct where they go.
How long does it take to get licensed in the states we operate in?
Typically 12 to 24 months for a multi-state footprint, with the largest states at the long end. Operating as an authorized delegate under a licensed principal compresses that to weeks, subject to the principal covering your flow.
Does a stablecoin rail avoid the license?
No. Transmitting value for others is money transmission on any rail. The stablecoin itself is regulated under the GENIUS Act, and the transmitter is regulated under the Bank Secrecy Act and state law.
What does a scoping review look at?
Who pays, who is paid, where funds rest and for how long, who controls the account, how the fee is taken, which states the parties are in, and what the contracts actually say. Most flows are clear within the hour, and the answer is sometimes that the model needs changing before any license or principal can cover it.
