Short answer: When you default on an MCA, the funder accelerates the full balance, hits your bank account with NSF and reversal fees, files UCC notices to intercept your receivables, sues you and your personal guarantor, and in some cases, freezes your accounts within hours through a restraining order. There’s no grace period. There’s no federal consumer protection. You’re on a clock the moment you miss the first ACH.
Here’s what actually happens, in roughly the order it happens, so you know what you’re walking into.
1. The ACH gets redone. Then redone again.
Most funders will retry the daily debit two or three times after the first NSF. Each retry triggers an NSF fee from your bank, and a returned payment fee from the lender. A single missed week can stack over $500 in fees, before the lender has even picked up the phone.
And this is by design. The bank fees aren’t a side effect — they’re the first squeeze.
2. The in-house collections team starts calling.
Most MCA lenders have an in-house collections desk, and they are aggressive on purpose. Expect calls on your business line, your cell phone, and your personal guarantor’s phone, all within 48 hours. Some lenders will start calling customers and vendors who show up on your bank statements. They have full rights to do that.
A few will threaten you in ways that feel illegal — fake “process server” calls, threats to show up at your home, threats against family members. Document everything. Save voicemails.
3. The balance gets accelerated.
The purchased amount, (what you owe), becomes due immediately in full. You no longer owe the daily payment. You owe the entire remaining balance, plus default fees, plus attorney fees, plus whatever else the agreement allows.
A $150,000 deal with $80,000 left becomes $80,000 due tomorrow. Not over six months. Tomorrow.
4. The UCC-1 gets activated.
When you took the MCA, the lender filed a UCC-1 financing statement against your receivables. At default, they send notices to your credit card processor, your customers, and anyone else who pays you, instructing them to redirect payments to the funder.
Done correctly by the lender, your cash flow gets choked off within a day. You’ll see deposits stop hitting before you’ve finished reading the demand letter.
5. They file suit. Almost always in New York.
Most MCA lenders will file in New York, regardless of where your business is located, because the agreement contains a New York forum selection clause. The lawsuit names the business, and every personal guarantor on the original application.
If the agreement is older, or from certain lenders, it may include a Confession of Judgment — though New York law has restricted COJs against out-of-state defendants since 2019. Newer agreements skip the COJ and go straight to summary judgment, which is almost as fast.
6. They get a TRO that freezes your accounts.
This is the one most business owners don’t see coming. The lender can apply for a Temporary Restraining Order, and in some jurisdictions get it granted ex parte, meaning without notice to you. Within hours, your business and personal bank accounts are frozen. Payroll bounces. Rent bounces. Vendors stop shipping.
You find out about the TRO when your card gets declined at lunch.
7. The personal guarantee gets enforced.
Almost every MCA agreement includes a personal guarantee, even when the funding is structured as a “purchase of receivables” rather than a loan. At default, the guarantor (you, usually) becomes personally liable for the full accelerated balance.
That means your house, your savings, your personal accounts, your spouse’s joint accounts — all in play. The corporate veil doesn’t help you here, because you signed it away on page 8.
8. A lockbox gets put on your receivables.
If the funder gets a judgment, or sometimes before, they can install a lockbox arrangement that routes 100% of your incoming payments to a controlled account. They take their cut, then release what’s left. Sometimes nothing is left.
This is different from the UCC notice in #4 — that’s a redirect. A lockbox is a full takeover of your cash flow.
9. Your future financing dies.
The default, the UCC filings, and the judgment all show up. Other MCA lenders share data through industry databases, traditional lenders pull UCC searches, and any judgment is public record. Once you’ve defaulted on one MCA, getting clean financing of any kind, becomes nearly impossible for years.
This is the part nobody talks about until it’s too late. The default itself is survivable. The exile from the credit market afterward is what kills the next business you try to build.
The 30 second takeaway
Default on an MCA, and within 72 hours you’re looking at stacked NSF fees, a fully accelerated balance, intercepted receivables, and a lawsuit filed in New York. Within two weeks, you may be looking at a frozen bank account and personal liability for the full amount. There is no grace period, there is no federal protection, and waiting it out is not a strategy.
