MCA broker vs ISO

MCA broker vs ISO is a distinction that sounds bureaucratic but actually matters: it determines the merchant's regulatory protection, the commission structure on the deal, the data flow to the funder, and the recourse the merchant has if something goes wrong. Understanding which type of intermediary is selling the deal is one of the highest-leverage pieces of due diligence a merchant can do.

The mechanics — what an MCA broker is. "Broker" is the generic, informal label for anyone who connects a merchant to a funder in exchange for compensation. There is no licensing requirement at the federal level; only a few states (CA, NY effective 2024, NJ, VA, GA) require broker licensing or disclosure registration. A broker can be:

1. A 1-person LLC operating from a home office with no funder contracts.
2. A 10-person call center pitching warm leads bought from lead-generation companies.
3. A formal ISO with direct contracts at 30+ funders.
4. A loan officer at a bank cross-referring outside their bank's product set.

Brokers may or may not have direct funder relationships. Many "brokers" actually sub-broker — they submit the deal through a different broker who has the funder relationship, layering an extra commission slice into the deal.

The mechanics — what an ISO is. ISO (Independent Sales Organization) is a formal contractual designation. To be an ISO, the broker must:

1. Sign an ISO Agreement with the funder. This is a contractual document that defines commission rates, exclusivity (or non-exclusivity), submission process, marketing rules, and dispute resolution.
2. Receive a unique ISO code from the funder. Every deal the ISO submits is tagged with this code for commission tracking.
3. Pass the funder's due diligence — typically background check on principals, financial review, sometimes E&O insurance requirement.
4. Comply with the funder's marketing standards (no misleading advertising, no false APR claims, no spam outreach in regulated states).

A broker with no ISO agreements anywhere is a pure sub-broker. A broker with one ISO agreement is a "single-shop ISO." A broker with 20+ ISO agreements is a "multi-funder ISO" or "shop" — the typical structure for any serious MCA business.

The math — commission economics. The distinction matters financially because of how commissions flow.

Direct ISO submission: - Broker (ISO) submits deal directly to funder. - Funder pays ISO 8-15% commission on the funded advance. - Example: $100K advance, 12% commission = $12K to ISO. Merchant's wire is net of broker fee depending on structure (some funders gross up commissions into factor; others wire net).

Sub-broker submission (broker without ISO contract): - Broker submits to a connected ISO, who submits to the funder. - Funder pays the ISO 12% = $12K. - ISO splits with sub-broker, typically 50/50 = $6K to each. - Both parties have incentive to inflate factor rate or layer extra fees to justify their cut. - Merchant typically pays 1-3 points more on factor than a direct ISO deal.

Multi-layer broker chains: - Some deals pass through 3+ intermediaries. Each takes a slice. - Final commission load can reach 18-25% of advance. - Merchant is paying for the chain even though only one party is doing real work.

The strategic insight — how to tell the difference. Five questions to ask any broker before engaging:

1. "Are you an ISO with [funder name] directly, or do you sub-broker through someone?" A direct ISO will name specific funders; a sub-broker will hedge with "I work with a network of partners."
2. "What's your ISO code at [funder]?" A real ISO can produce the code on the spot; a sub-broker will deflect.
3. "Can my offer letter come directly from the funder, or does it route through your firm?" Direct ISO deals get direct offer letters; sub-brokered deals often pass through the ISO's email.
4. "What's your commission percentage on this deal?" Funders publish typical commission ranges (8-15%); a broker quoting 6% is likely a sub-broker getting a partial split; one refusing to answer is hiding a multi-layer chain.
5. "Are you licensed/registered in [my state]?" California, New York, New Jersey, Virginia, and Georgia have broker disclosure or registration requirements. A broker operating without compliance in those states is operating illegally and offers the merchant zero recourse.

The strategic insight — why direct ISO matters. Three concrete merchant benefits:

1. Lower pricing. Direct ISO deals carry 5-15% lower factor pricing on average because there's only one commission layer.
2. Faster operational response. When something goes wrong (NSF, reconciliation, buyout), the direct ISO has the funder relationship to resolve it. Sub-brokers have to triangulate through the ISO in the middle, slowing everything by 2-5 days.
3. Regulatory recourse. In states with broker disclosure laws, the direct ISO is on the hook for compliance. Sub-brokers and unlicensed brokers offer no regulatory protection — if the deal is misrepresented, the merchant has no enforcement path.

The honest framing. Most merchants don't know if they're dealing with an ISO or a sub-broker — and the broker won't volunteer the distinction. Asking the five questions above costs nothing, takes 60 seconds, and reveals whether the merchant is shopping with a real intermediary or being passed through a commission chain. It's the single highest-leverage piece of due diligence in the entire MCA shopping process.
