MCA NSF fees explained

When your MCA payment bounces, you don’t just owe the payment. You owe the payment, plus fees from your bank, plus fees from the funder, plus whatever the funder tacks on for the “inconvenience” of you not having money. And they’ll try the debit again. And again.

Short answer: An NSF on an MCA triggers fees from two directions at once – your bank charges you $27-$39 for the returned ACH, and the funder charges you a returned payment fee that’s typically $35-$100 per occurrence. Most funders will re-attempt the debit two or three times. Every attempt that fails is another round of fees from both sides. A single bad week can cost you $300-$600 before you’ve paid a dollar toward the actual advance. And if the NSFs keep happening, the funder will declare you in default, and accelerate the full balance.

What NSF actually means on an MCA

NSF stands for Non-Sufficient Funds. It means the funder tried to pull your daily or weekly payment via ACH, and your bank account didn’t have enough to cover it. The bank rejects the debit. The funder gets a returned payment notice. You get hit with fees.

The thing most business owners don’t realize: on a traditional loan, an NSF is an inconvenience. On an MCA, an NSF is a contractual event. Your MCA agreement almost certainly defines repeated NSFs, or any NSF at all, as a breach. The funder doesn’t have to wait. They can act the same day.

The fee stack – what you’re actually paying

Here’s what a single NSF on an MCA actually costs you, and who’s charging what:

• Your bank charges an NSF fee. Usually $27-$39. Some banks charge this per attempt, so if the funder re-tries the debit three times, you pay it three times.
• The funder charges a returned payment fee. Typically $35-$100. Written into the MCA agreement. Non-negotiable.
• Some funders charge a “default fee” on top. $2,500-$5,000 is common. This shows up the moment they classify you as in default, which can happen after a single NSF depending on the contract.
• Some funders add a “blocked ACH fee.” If they believe you instructed your bank to block the debit (as opposed to just not having funds), this fee can run $2,500-$10,000.
• Attorney fees and collection costs. Written into virtually every MCA agreement. Gets added to your balance the moment the funder sends the file to their in-house legal team, or to outside counsel.

A single missed week, with three re-attempts, can look like this:

• 3 bank NSF fees at $35 each = $105
• 3 funder returned payment fees at $50 each = $150
• 1 default fee (if triggered) = $2,500

That’s $2,755 in fees on a single week of missed payments. Before the funder has even picked up the phone.

Why funders re-attempt the debit multiple times

This confuses a lot of business owners. You’d think one NSF would be enough.

It’s not, and the re-attempts are intentional. Most funders will try the debit two to three times over the following days. A few reasons for this:

• Some genuinely expect the deposit to land in your account soon, and want to capture the funds the moment they’re there
• Some are running automated ACH re-attempt rules that trigger without human review
• Some are doing it to rack up fees on purpose, because the fees are real revenue for the funder
• Some are doing it to establish a paper trail of failed debits, so they can accelerate the balance with documentation

Whatever the reason – every re-attempt is another fee on both sides. Your bank doesn’t care why the funder tried again. They’re going to charge you either way.

Can you stop the funder from re-attempting?

Technically yes. Practically – be careful.

You can call your bank and place a stop payment on that specific ACH, or you can block the originator ID. Both of these will prevent the funder from pulling again.

Here’s the problem. Under almost every MCA agreement, blocking the ACH is a separate event of default, distinct from the NSF itself. Many funders specifically write in a “blocked ACH fee” – often $2,500 to $10,000 – that triggers the moment they detect you’ve blocked them. They detect it because the bank’s return code on a blocked debit is different from the return code on an NSF.

So blocking the debit can actually be worse than letting it bounce. Letting it bounce gives you an NSF and the standard fees. Blocking it gives you an NSF equivalent, plus the blocked ACH fee, plus a cleaner default argument for the funder.

If you’re considering blocking the ACH, you should be talking to someone who handles MCA defaults before you do it. Not after.

What happens when the NSFs keep coming

One NSF is an event. Three NSFs in a row is a pattern. And funders treat patterns as proof.

Here’s the sequence that typically plays out:

1. First NSF. You get a call, sometimes same day. It’s usually polite-ish. They want to know when the money will be there. They’ll often re-attempt the debit within 48-72 hours.
2. Second NSF. The tone changes. The call now comes from someone more senior, or from collections. They start asking about your bank account, your revenue, your other advances.
3. Third NSF, or NSFs across multiple weeks. The funder declares default, sends a notice of acceleration, and the full remaining balance becomes due. Collections calls escalate. Some funders at this point will start contacting customers on your bank statements, and instruct your credit card processor to redirect payments.
4. Legal. If the balance is large enough, and many funders have extremely low thresholds for this, the file goes to their attorneys. You get sued, often in New York regardless of where your business is located, because the MCA agreement has a New York venue clause.

The NSF fees you racked up along the way? They’re now part of the accelerated balance. You’re paying attorney fees to collect on attorney fees.

What you should actually do if you’ve had an NSF

Don’t panic, but don’t wait. The window to fix this is measured in days, not weeks.

• Call the funder before they call you. If your deposit is coming Thursday and the debit failed Monday, tell them. A proactive call changes how they classify you internally. It doesn’t eliminate fees, but it often stops the re-attempt cycle.
• Don’t lie about why. Funders have seen every excuse. “The bank made an error” is the one that ages worst, because they can verify it in about ten minutes.
• Don’t open a new bank account and move your deposits. This is one of the fastest ways to turn a fee problem into a fraud allegation. Funders watch for this, and the MCA agreement explicitly defines it as default.
• Don’t take another MCA to cover the shortfall. The stacking clause in your current agreement almost certainly prohibits this, and the second funder’s underwriting will often catch the NSF and either decline you or price it accordingly.
• Get on the phone with someone who handles MCA defaults. Not a general business attorney. Not your accountant. Someone who does this specifically. The moves available to you at week one are completely different from the moves available at week four.

The part no one tells you

The NSF fees are not the actual problem. The NSF fees are the signal of the actual problem.

If you’re bouncing MCA payments, it means the daily debit has exceeded what your business can sustain. That doesn’t get better by itself. It gets worse. Every week you let it ride, the balance grows, the fees compound, and the funder’s options expand while yours contract.

The business owners who come out of this okay are the ones who act while they still have leverage. The ones who call us at month three, after the lawsuit has already been filed, after the accounts have already been frozen, after the customers have already been contacted – they have fewer cards to play. Not zero. But fewer.
