How MCA Brokers Handle Merchant Disputes and Chargebacks in 2026

When Deals Go Sideways: What Every MCA Broker Needs to Know About Disputes

Placing a merchant with a funder is the easy part. What happens when the deal sours -- when a merchant calls screaming that an ACH pulled twice, when a funder claws back your commission because the business closed, or when a merchant threatens legal action over an advance they claim was 'not what they signed'? These scenarios happen in every MCA brokerage. How you handle them separates professionals who build long careers from those who burn relationships and end up facing liability.

This guide covers the full landscape of MCA merchant disputes and chargebacks: what causes them, what your obligations are, how to protect yourself before a deal funds, and what to do when things go wrong after funding. If you're new to the industry, bookmark the MCA glossary for terminology you encounter along the way.

Understanding the Dispute Landscape in MCA

Unlike traditional loans where disputes flow through regulated channels, MCA disputes live in a murkier legal space. The MCA-is-not-a-loan distinction matters here: because MCAs are purchase-of-future-receivables agreements, consumer protection laws like the Fair Debt Collection Practices Act generally do not apply. But that legal gap cuts both ways -- merchants have fewer formal remedies, which means more informal ones like ACH revocations, bank chargebacks, and social complaints.

Disputes in the MCA world typically fall into four categories:

• ACH revocation disputes -- merchant tells their bank to block ACH debits
• NSF and return events -- failed payments that funders treat as defaults or credit events
• Contract disputes -- merchant claims they were misled about terms, rate, or total payback
• Commission clawback disputes -- funder demands back some or all of your ISO commission due to early default or fraud

Each type requires a different response, and your liability exposure varies significantly across them.

ACH Revocations: What Actually Happens and What You Should Do

When a merchant instructs their bank to block ACH debits, the funder stops receiving payments. Depending on the agreement, this may trigger an immediate default, acceleration of the entire balance, or legal action under the confession of judgment clause if one exists in the contract.

As a broker, you are not a party to the contract. You cannot force a merchant to keep payments running, and you should not pretend otherwise. What you can do:

• Stay neutral and document everything. If the merchant contacts you after revoking, listen carefully and write down the substance of every call. Do not make promises about outcomes.
• Contact your ISO rep at the funder. Alert them immediately that the merchant has revoked. Early communication preserves goodwill and sometimes lets the funder work out a modified payment arrangement before escalating to collections.
• Do not coach the merchant on avoiding the funder. Helping a merchant evade an obligation you facilitated creates real legal exposure for you -- potentially tortious interference or aiding a breach of contract.

For context on why ACH events are treated so seriously by funders, read our guide on MCA ACH returns and NSF events. Funders track return rates carefully, and a broker who consistently places merchants who revoke will find their programs getting restricted.

The NSF Spiral: When Returns Stack Up

NSF (non-sufficient funds) returns are different from deliberate revocations -- they usually indicate a merchant in genuine financial distress. When a merchant's account repeatedly returns ACH debits, here is what typically unfolds:

1. The funder receives 1-3 NSFs and may pause collections while investigating
2. The funder contacts the merchant and may offer a modified payment plan
3. If NSFs continue, the advance is placed in a default or workout status
4. A collections process begins -- either internal or through a third-party agency
5. The funder reviews whether the original deal was properly underwritten
6. If underwriting deficiencies are found, a commission clawback is issued to the broker

As a broker, your best protection against NSF cascades is pre-qualification. Strong pre-qualification means you're catching distressed merchants before submission, not after. Check bank statement analysis carefully: look for NSF history, overdraft fees, and negative average daily balances in the last 30 days. These are predictors of post-funding payment trouble.

Commission Clawbacks: Protecting Your Earnings

One of the most financially painful disputes a broker faces is a funder clawing back your ISO commission. This happens most often when:

• The merchant defaults within the first 30-60 days (first payment default or FPD)
• The merchant files bankruptcy shortly after funding
• Fraud is discovered -- forged bank statements, fake revenue, identity issues
• The broker is found to have misrepresented the deal to the funder

Read the dedicated guide on how brokers protect commissions from clawbacks for detailed defense strategies. The short version: your ISO agreement with the funder defines clawback terms, and many are negotiable at signing. Key things to push for before you start submitting deals to any funder:

• A defined clawback window -- ideally 30 days maximum, not open-ended
• Pro-rata clawback rather than 100% return -- if the deal funded $50k and paid back $30k before defaulting, you should owe a fraction, not the full commission
• Fraud carve-outs only -- clawbacks should apply to fraud or misrepresentation, not general credit defaults
• Written notice requirements -- the funder must notify you within X days of identifying a clawback event, giving you time to respond

Contract Disputes: When Merchants Claim They Were Misled

The most legally dangerous disputes for brokers involve merchants claiming they were misled about the terms of their advance. These claims often sound like:

• 'I was told this was a loan with interest, not a fixed purchase amount'
• 'Nobody explained that payments would be daily'
• 'The broker told me I could get out of this any time'
• 'I never agreed to a personal guarantee'

Several states now require specific disclosures. California's SB 362, New York's commercial financing disclosure law, and a growing list of state regulations mandate that merchants receive an APR-equivalent disclosure before signing. Review the compliance guides for California SB 362 and New York's disclosure law -- these are the two strictest regimes as of 2026, and both impose obligations on brokers, not just funders.

Your defense against contract dispute claims starts before the deal closes:

• Never summarize terms verbally without directing the merchant to the written contract. Anything you say over the phone that contradicts the written agreement is a liability.
• Walk merchants through the total payback amount explicitly. Our MCA underwriting calculator is a good tool to use with merchants -- it shows factor rate, total cost of capital, and effective APR in plain English. When you show a merchant their total payback before they sign, it is much harder for them to claim they were deceived.
• Get signed acknowledgment. Many brokers now have merchants initial a separate disclosure page that summarizes key terms in plain language: amount advanced, total payback, payment frequency, and that this is a sale of receivables, not a loan.

The Broker's Role When a Merchant Calls in Crisis

When a funded merchant calls you in distress -- they can't make payments, the funder is calling, they're considering closing -- your role is limited but important. Here is a practical framework:

Listen First, Advise Carefully

Understand what the merchant is actually experiencing. Is it a temporary cash flow problem or a structural business failure? If it's temporary, a reconciliation clause may allow modified payments -- point the merchant to this option and connect them with your ISO rep at the funder.

Know What You Can and Cannot Promise

You cannot promise that the funder will modify payments, forgive a balance, or delay collections. Making these promises exposes you to fraud claims if they don't come true. What you can promise: that you will connect them with the right person at the funder, and that you will advocate for a fair outcome.

Document Every Interaction

Write a contemporaneous note after every call with a distressed merchant. Include the date, what was said, what was asked, what you promised or didn't promise, and any next steps. If this merchant ever files a complaint or lawsuit, your notes are your evidence.

Consider a Hardship Referral

If the merchant's business is genuinely failing, a referral to a business restructuring advisor or attorney is sometimes the most ethical option. It's not your job to rescue every deal -- it's your job to act in good faith. Our guide on distressed merchant hardship situations walks through these scenarios in detail.

Funder Disputes: When You Disagree with the Funder

Not all disputes are merchant-vs-funder. Sometimes the broker is in conflict with the funder -- over a clawback decision, a deal submission that got turned down without explanation, or a stacking accusation that you believe is unfair.

These disputes require a different playbook:

• Read your ISO agreement carefully before pushing back. Most disputes come down to contract interpretation. Know what your agreement says about dispute resolution, arbitration clauses, and jurisdiction.
• Put your disagreement in writing. A phone call is not enough. Send a formal email or letter stating your position clearly and requesting a response within a defined timeframe.
• Escalate to senior management or an ISO relations contact. Front-line underwriters and ISO reps rarely have authority to resolve a clawback dispute. Ask to speak with someone in ISO relations, compliance, or legal.
• Know when to walk away. A funder who routinely issues unjustified clawbacks, changes programs without notice, or fails to pay commissions is not a partner worth keeping. The ability to search our funder directory and find alternative funders is exactly why maintaining a broad panel matters.

Prevention: The Best Dispute Is the One That Never Happens

The single most effective way to reduce disputes is to match merchants to funders whose programs genuinely fit the merchant's profile. Overfunding, placing a merchant with a program they can't sustain, or submitting to the wrong funder because the commission is higher -- these decisions create disputes downstream.

Use the underwriting calculator to pressure-test every deal before submission. Run the daily payment against the merchant's average daily balance. If the payment is more than 15-20% of their average daily balance, the deal is likely to strain. Many brokers use this as a hard filter.

Build a funder panel that includes multiple options at each credit tier so you can genuinely match, not just place. The guide to building a funder panel covers this in detail. When you have real alternatives, you won't feel pressure to force a merchant into a program they shouldn't be in.

Finally, invest in your disclosure process. The regulatory landscape is moving in one direction -- more disclosure, more transparency, more broker accountability. Brokers who get ahead of this now, who have clean paper trails and educated merchants, will be far less exposed when regulators come calling.

E&O Insurance: Your Financial Safety Net

Even with best practices, disputes happen. Errors and omissions (E&O) insurance is your backstop against the financial consequences of a dispute that escalates to a claim. If you don't have E&O coverage, read the MCA broker E&O insurance guide before your next deal closes. Coverage is more affordable than most brokers expect, and a single claim can dwarf years of premiums.

Practical Takeaway

MCA disputes are not a sign of failure -- they are a normal part of the business. What separates experienced brokers from vulnerable ones is preparation: strong pre-qualification to catch at-risk merchants before funding, clear verbal and written disclosures to eliminate misunderstanding, documented interactions to build a defensible paper trail, and an ISO agreement that limits clawback exposure to genuine fraud rather than general default.

The brokers who handle disputes well tend to have the fewest of them -- because their practices prevent the conditions that create disputes in the first place. If you're looking to build a more sustainable, dispute-resistant book of business, start by creating your broker account and accessing our verified funder directory, where you can review program terms and find funders with transparent, broker-friendly policies.
