How to Stop Daily ACH Debits from Your Business Account

Daily MCA debits drain operating cash before payroll, rent, or vendors can clear. When the debits exceed the cash flow that can sustain them, the standard advice is to stop the debits. That advice is right, but the mechanism matters. Done correctly, stopping the debits buys breathing room without triggering default escalation. Done wrong, it accelerates collections and exposes the business to confession of judgment filings. This article walks through the three mechanisms, when each fits, and the letter language that makes them work.

TL;DR

• Three mechanisms stop MCA debits: contractual reconciliation, ACH revocation through the bank, and account protection through routing changes.
• Reconciliation is the preferred path. It uses contract language to reduce or pause debits without triggering default.
• ACH revocation is faster but triggers default in most contracts. Use only when reconciliation is refused or impossible.
• Account protection (moving operating cash to a new bank not on the funder's records) is supplemental, not standalone, and has limits.
• A documented reconciliation request, sent the right way, gets a response from most funders within 5 to 10 business days.
• Stopping the debits is the first step in a workout. Without a parallel settlement or restructure plan, the funder will accelerate within 30 to 60 days.

Why the mechanism matters

MCA contracts treat any unauthorized interruption of the daily debit as a default event. The default triggers acceleration of the full balance, can trigger confession of judgment filings, and routes the file from collections to litigation. The wrong mechanism turns a $200K problem into a $260K problem with a frozen account.

The right mechanism uses the contract's own language against the contract. Most MCAs include a reconciliation clause that gives the merchant a contractual right to request adjustment when actual revenue does not match the funder's projection. Using that clause does not trigger default. It triggers a workout conversation.

Mechanism 1: contractual reconciliation

Reconciliation is the preferred mechanism. It uses the contract.

How reconciliation works

The standard MCA reconciliation clause reads approximately like this:

"If, in any given month, the daily debits cause the actual percentage of Daily Receipts collected to exceed the Specified Percentage stated in this Agreement, the Merchant may request a reconciliation. Upon receipt of documentation supporting such request, the Funder will adjust the Daily Debit amount to reflect the Specified Percentage applied to the Merchant's actual Daily Receipts."

The clause exists because MCAs are structured as a purchase of future receivables, not as a loan. If the receivables are not coming in at the projected rate, the daily debit must adjust or the legal characterization of the contract breaks. Funders that refuse reconciliation are exposing their contracts to recharacterization risk in court.

What to send

The reconciliation request is a written letter, sent by email and certified mail. It includes:

• Identification of the contract and merchant
• A statement that the actual daily debit is exceeding the contractual Specified Percentage
• Documentation: 90 days of bank statements showing actual deposits
• A calculation of the corrected daily debit based on actual deposits
• A request that the funder reduce the debit to the corrected amount effective immediately
• A deadline for response (10 business days is standard)

Example language:

"Pursuant to Section [X] of the Agreement, [Merchant LLC] hereby requests reconciliation of the Daily Debit. Actual Daily Receipts over the trailing 90 days have averaged $[amount], significantly below the projection underlying the Daily Debit of $[debit]. Applying the Specified Percentage of [X percent] to actual Daily Receipts yields a corrected Daily Debit of approximately $[corrected amount]. We request that the Daily Debit be adjusted to this amount effective with the next debit cycle. Supporting documentation is attached. We expect a response within 10 business days of receipt."

What happens next

Funders respond to reconciliation requests in three ways.

Grant the request. The funder adjusts the debit. This happens about 30 to 40 percent of the time, especially with institutional funders that understand the legal exposure of refusing.

Counter the request. The funder offers a partial adjustment or requests additional documentation. This happens about 40 percent of the time. The counter is the opening of a negotiation, and most counters can be moved toward the merchant's number with one or two rounds.

Refuse the request. The funder ignores the request or explicitly refuses. This happens about 20 to 30 percent of the time, more often with aggressive small funders. Refusal of a documented reconciliation request is itself useful evidence in a later settlement negotiation or litigation, because it shows the funder is treating the contract as a loan rather than as a true receivables purchase.

When reconciliation does not work

Reconciliation has limits.

Some contracts do not include a reconciliation clause. These are older or particularly aggressive contracts. Without the clause, the contract language does not provide a no-default path to debit reduction.

Some funders refuse to engage. They are betting that the merchant will not litigate. They are sometimes right.

Some contracts have already accelerated. Once acceleration has been declared, reconciliation is no longer the operative mechanism. The contract is in default and the conversation is about settlement.

Mechanism 2: ACH revocation

When reconciliation is refused or unavailable, ACH revocation through the bank is the faster path. It also triggers default.

How ACH revocation works

Under NACHA rules and Regulation E (for personal accounts) or commercial bank policies (for business accounts), the account holder can revoke ACH authorization at any time. The mechanism is a written instruction to the bank, with a copy to the originator, stopping further ACH debits.

The bank is obligated to honor the revocation within 1 to 3 business days. Subsequent debits attempted by the funder are returned with code R10 (customer advises unauthorized) or R29 (corporate customer advises unauthorized).

The trade-off

ACH revocation works fast. The debits stop within days. The funder cannot easily reinstate them without a new authorization, which the merchant will not provide.

ACH revocation also triggers default under almost every MCA contract. The default triggers the funder's escalation: phone calls, collection letters, demand for payment of the full accelerated balance, and potentially confession of judgment filing.

The merchant needs a settlement plan in place before pulling this trigger. Without a plan, the time between debit stop and COJ filing is 30 to 60 days, sometimes less.

Letter language for ACH revocation

The revocation letter goes to the bank and the funder simultaneously.

To the bank:

"Pursuant to NACHA Operating Rules and the account agreement, [Merchant LLC] hereby revokes all ACH authorizations on account [number] in favor of [Funder Name]. Please block all further ACH debits originating from [Funder Name] or any affiliated originator. Return any future ACH debit attempts as R29 (corporate customer advises unauthorized). This revocation is effective immediately."

To the funder:

"Effective [date], [Merchant LLC] has revoked the ACH authorization underlying the Daily Debit under Agreement [number]. Future debit attempts will be returned as unauthorized. [Merchant LLC] remains open to discussion of a settlement or restructure of the outstanding balance and will follow up separately with a settlement proposal."

The second paragraph is critical. Pairing the revocation with explicit settlement engagement positions the merchant as acting in good faith on the underlying obligation, even while stopping the unauthorized mechanism. This matters in any subsequent litigation.

Mechanism 3: account protection

The third mechanism is supplemental: protecting operating cash by routing it through accounts the funder does not have on file.

How account protection works

Most MCA contracts list a specific bank account for the daily debit. The funder's records show that account. If operating cash flows through a different account, the funder cannot debit it directly.

Mechanically: open an operating account at a bank not on the funder's records. Route customer payments to the new account. Keep only a minimum balance in the listed account to cover any debits that still go through.

Limits

Account protection has real limits.

UCC filings cover all receivables, not just the listed account. The funder can serve a UCC notice on the new bank if they identify it, and the bank may then freeze the account.

The funder's records can update. If the merchant files a tax return, a loan application, or anything else that names the new bank, the funder may discover it and update their records.

Personal guarantors' accounts are separately exposed. If the guarantor's personal accounts are at the same bank or are identifiable, those become targets after the business accounts are exhausted.

Account protection works best as a 30 to 90 day bridge during which a settlement or workout is being negotiated. It does not work as a long-term solution.

Coordination with liquidity engineering

Account protection should be coordinated with a broader liquidity plan. Which accounts hold cash. Which accounts receive deposits. Which accounts pay vendors. The architecture matters because the funder is looking for the cash. A clean architecture buys time. A sloppy architecture creates fraud exposure if the moves look like asset hiding.

Sequencing the three mechanisms

The mechanisms work best in sequence, not in parallel.

Step 1: send the reconciliation request. Wait 10 business days.

Step 2: if reconciliation is granted, the debits adjust. Move to settlement or restructure planning on the new debit level.

Step 3: if reconciliation is refused or ignored, prepare the settlement proposal and the ACH revocation simultaneously. Send both within the same 5 day window.

Step 4: in parallel, open account protection at a new bank and begin routing.

Step 5: engage counsel on COJ defense before the revocation lands, not after.

The sequence preserves the contractual high ground (reconciliation first), accelerates only when necessary (revocation), and protects operations during the transition (account protection). Skipping steps or running them in the wrong order produces worse outcomes.

What to do next

If the daily debits are no longer sustainable, the first move is the reconciliation letter. The second move is the settlement plan. The third move is the bank architecture. All three need to be coordinated, because each one trips wires in the others.
