The 60-second answer
ISO brokers serve a legitimate function: they shop your application across multiple funders, navigate paperwork, and can place merchants whose profiles don't fit standardized direct-funder underwriting. But the broker model is structurally conflict-laden — brokers earn commission on every deal funded, which means they're incentivized to close any deal, not the best deal for you.
The 12 red flags below help you spot brokers who are extracting value from you rather than adding it. Most fall into three categories: opacity (won't show you the underlying funder or commission), pressure (rushing you to sign), and misrepresentation (claiming exclusivity, guaranteed approvals, or capabilities they don't have).
Red flag 1: refuses to disclose their commission
The single cleanest test of broker integrity. Ask directly: "What percentage commission do you earn on this deal?" Reputable brokers answer immediately with a specific number (typically 8-12% of funded amount). Brokers who deflect, claim "it doesn't affect your rate," or give vague answers are almost always marking you up significantly.
The deflection lines to watch for: "The funder pays me, not you" (true but misleading — the funder pays the broker out of YOUR factor markup), "Commission varies by deal" (rare), "I don't think about my commission, I think about your needs" (a non-answer).
Red flag 2: won't tell you which funder will hold your contract
A reputable broker tells you the funder name upfront. Brokers who keep the funder identity secret until you sign are usually either (a) double brokering through another intermediary, (b) placing you with a substandard funder they don't want you to research, or (c) hiding the fact that you could go direct to the same funder at a lower factor.
You have an absolute right to know which entity will hold your contract before signing. Refuse to sign without this information.
Red flag 3: shows you only their quote, never the funder's underlying quote
A clean broker relationship: the broker shows you the funder's wholesale quote and the broker's retail quote side-by-side, with the markup transparent. Most brokers don't do this because seeing the markup explicitly makes merchants question whether it's justified. If your broker won't show you the underlying funder quote, assume the markup is larger than the broker would want you to see.
Red flag 4: pressures you to sign within 24 hours
MCA offers are typically valid for 5-7 business days. Brokers who pressure you to sign today, this hour, or before someone "withdraws the offer" are using artificial scarcity. The honest pitch: "The offer is good for 5 business days. Take what time you need to compare." Pressure-selling is a signal the broker is worried you'll find a better deal if you shop.
Red flag 5: discourages you from getting other quotes
"Why are you wasting time getting other quotes? We're the best deal you'll find" is almost always false. The only way to know if you have the best deal is to compare. A reputable broker says: "Get other quotes, then come back and we'll match or beat what you find."
Red flag 6: won't put their commission in writing
Even brokers who verbally disclose commission sometimes won't put it in writing. The written disclosure is what creates accountability. If the broker refuses to email or provide a one-page commission disclosure, treat that as evidence the commission is higher than what they're saying verbally.
Red flag 7: routes you to a single funder repeatedly
A broker with broad funder access shops your application across 10-20 funders to find the best match. A broker who routes every merchant to the same one or two funders is either (a) an exclusive ISO for those funders (which is fine if disclosed but limits your options) or (b) earning bonus tier commission from those specific funders for volume. Either way, your interest may not be served.
Red flag 8: charges "application fees" or "underwriting fees" upfront
Legitimate MCA applications are free. The funder pays the broker commission out of the factor — there's no merchant-paid fee. Any broker charging upfront fees ($199, $499, $999) for "application processing" or "underwriting fees" is either scamming or running a parallel revenue stream on top of commission. Refuse to pay.
Red flag 9: misrepresents the factor as an "interest rate"
A factor rate is not an interest rate. A broker who calls a 1.30 factor a "30% interest rate" is either ignorant or actively misleading you. The 1.30 factor on a 12-month MCA works out to roughly 50% APR-equivalent — substantially higher than the 30% the broker implied. This misrepresentation is becoming increasingly subject to enforcement under state disclosure laws.
Red flag 10: doesn't mention prepayment terms
Brokers earn commission on the gross funded amount. They have no financial interest in your ability to pay off early at a discount. Brokers who don't proactively explain prepayment terms — or who tell you prepayment terms "don't matter" — are usually placing you with funders who don't offer prepayment discounts. About 30% of MCA funders do offer prepayment discounts, and you should know which group your contract falls into BEFORE signing.
Red flag 11: hides reconciliation clause status
A reconciliation clause allows the funder to lower your daily ACH if your revenue drops materially. About 40% of MCA contracts include meaningful reconciliation provisions; 60% don't. This is a material contract term. Brokers who don't proactively explain whether your contract has reconciliation are likely placing you with funders who don't offer it (because those funders pay slightly higher commission).
Red flag 12: claims "guaranteed approval"
Nobody can guarantee approval until the funder underwrites the deal. Brokers who guarantee approval are usually either (a) lying to get you to apply through them, or (b) planning to place you with a high-factor lender of last resort if better funders decline. Approval is never guaranteed for legitimate funding. Walk away from any broker who claims otherwise.
The four questions to ask any MCA broker
If you're working with a broker, ask these four questions and demand specific answers:
- What percentage commission do you earn on this deal, in writing?
- Which funder will hold the contract, and what's their wholesale quote vs the quote you're showing me?
- What are the prepayment terms and reconciliation provisions in this contract?
- What other funders did you shop this application to, and what did each quote?
Brokers who answer all four clearly and specifically are the ones worth working with. Brokers who deflect on any of the four are signaling that something in your deal is not in your favor.
How to verify a broker is legitimate
Five verification steps that take 15 minutes:
- Check state licensing: Some states (CA, NY, NJ, others) require commercial financing brokers to register. Search your state's Department of Financial Institutions or equivalent.
- Check BBB and TrustPilot: Look for patterns in complaints — repeated mentions of hidden fees, undisclosed commission, or unauthorized contract terms are red flags.
- Verify business presence: Real address (not a UPS box), real phone number, actual website with leadership team listed.
- Check the FBI press releases: The 2026 ISO broker fraud investigation named 14 specific brokers. Make sure your broker isn't on that list.
- Ask for client references: Real brokers can provide 2-3 client references willing to verify the broker's conduct.
The economics of going direct vs through a broker
Worked example: $50K advance, same merchant profile, same funder.
Direct application
- Funder's wholesale quote: 1.28 factor
- Total payback: $64,000
- Fee: $14,000
Via broker
- Broker's retail quote: 1.38 factor (0.10 markup)
- Total payback: $69,000
- Fee: $19,000
- Broker commission embedded: $5,000
The $5,000 markup pays for the broker's service. Whether that service is worth $5,000 depends on whether (a) the broker actually placed you with a funder you couldn't have found yourself, and (b) the broker provided meaningful guidance that improved the deal structure. For most merchants who could go direct, $5,000 is too much for paperwork help.
When working with a broker actually makes sense
Three scenarios where the broker markup is justified:
- Specialized merchant profile: Cannabis, adult, firearms, or other industry-excluded merchants need brokers with specialist funder relationships
- Multiple-funder shopping: If you genuinely don't know which funders to apply to, a broker shopping across 15-30 funders saves you weeks of declined applications
- Complex deals: Stacked-MCA consolidations, post-bankruptcy restructures, or unusual collateral structures benefit from broker expertise
The regulatory direction (2026)
State disclosure laws are reshaping the broker landscape. California SB 1235, New York NYDFS Part 803, New Jersey SB 819, Texas SB 1280, Virginia commercial financing law, Utah commercial financing law, and Ohio SB 232 all require various forms of disclosure on commercial financing — including broker compensation in some jurisdictions.
The FBI's 2026 ISO broker fraud investigation (14 indictments, 3 convictions to date) targeted brokers running schemes including fake funder relationships, contract alteration after signing, and identity theft. The regulatory direction is clearer: brokers will be required to disclose more, document more, and operate more transparently. Merchants who learn to evaluate brokers critically today will be ahead of where regulation eventually lands.
Frequently asked questions
- How much do ISO brokers actually make on my MCA?
- Industry standard ISO commission in 2026 is 8-15% of the funded amount, paid by the funder out of the embedded factor rate markup. On a $50,000 advance, that's $4,000-$7,500 in broker commission that you're paying through a higher factor. Brokers who layer 'points' or 'fees' on top of commission can take 15-25% total — meaning a $50K advance could include $7,500-$12,500 in broker compensation.
- Can I find out if a broker is marking up my MCA?
- Yes — apply to the same funder directly (skipping the broker) and compare the factor you're quoted. The difference is the broker markup. Most direct funders will accept direct applications even if the merchant was originally introduced by a broker, particularly after 30+ days from initial broker contact.
- What's 'double brokering' and is it legal?
- Double brokering happens when an ISO broker shops your application to another ISO broker (rather than directly to a funder), and both layer commissions before the funder sees it. It's legal in most states but creates conflicts of interest — you're paying two broker commissions on top of the funder's base factor. NY, CA, and several other states are moving toward disclosure requirements that would make this visible. Today, you have to ask the broker directly: 'Are you the direct funder relationship or are you placing through another broker?'
- Are there any 'good' ISO brokers worth working with?
- Yes. Reputable ISO brokers disclose their commission upfront, charge fair markups (under 0.10 on factor), have direct relationships with 20+ funders, and decline deals that don't fit the merchant's interest. Look for brokers who provide written disclosure of their compensation structure, show you the funder's quote alongside theirs, and explicitly tell you when you'd be better served going direct.
- Are MCA brokers regulated like mortgage brokers?
- Inconsistently. Most states have minimal regulation of commercial financing brokers. NY's Truth in Lending Act, CA's Commercial Financing Disclosure Law, and similar laws in 6 other states require certain disclosures, but enforcement is patchy. The FBI's 2026 ISO broker fraud investigation resulted in 14 indictments and 3 convictions, signaling growing federal interest in the space. Until federal regulation lands, broker quality varies enormously.
