# MCA ACH pull mechanics

> The funder initiates a daily debit from the merchant's operating account via NACHA — typically a CCD or PPD entry of $300-$1,500/day, settling next business day, with a 2-day cure window on failed pulls and an NSF fee per bounce.

The daily ACH pull is the operational heart of every MCA. Understanding exactly how it works — entry classes, settlement timing, return windows, NSF mechanics, and the bank's role — is the difference between a merchant who manages their cash flow proactively and one who gets surprised by bounces, fees, and default escalation.

**The mechanics — what type of ACH entry is used.** MCA pulls are almost always:

1. **CCD (Corporate Credit or Debit) entries** — the standard business-to-business ACH classification. Allows the originator (the funder) to initiate a debit against the receiver's (merchant's) business account.
2. **Authorized via written FRSA + bank authorization form** — the merchant signs both the MCA contract and a NACHA-compliant authorization (often a "Voided Check ACH Form") at funding. The funder retains the authorization for the life of the deal and must be able to produce it on demand.
3. **Variable amount or fixed amount.** Most modern MCAs run fixed daily amounts (e.g., $620/day every business day). Some "true holdback" structures pull a percentage of daily card volume via the processor — different mechanic, covered separately.

**The mechanics — the daily timeline.** A typical pull on a Tuesday:

- **Monday 4-6 PM ET.** Funder's ACH operator (often a third-party processor like ACHWorks, Nuvei, or Repay) submits the day's batch to its ODFI (originating bank) for next-day settlement.
- **Tuesday 6 AM ET.** ODFI submits to the Federal Reserve ACH network.
- **Tuesday 8-11 AM ET.** Merchant's RDFI (receiving bank) processes the debit against the merchant's account. Most banks post by 11 AM ET; some delay until end-of-day.
- **Tuesday end of day.** Funds settle to the funder's account.
- **Wednesday-Thursday.** Return window. If the merchant's bank returns the entry (NSF, account closed, stop payment, unauthorized), the funder is notified within 2 business days.

**The mechanics — what happens on a failed pull.** If the Tuesday debit returns NSF on Wednesday:

1. **Funder's portal flags the bounce automatically.** Servicing team receives an alert by Wednesday afternoon.
2. **Re-pull policy.** Most funders re-attempt the debit Wednesday night for Thursday settlement. Some attempt up to three retries within a week.
3. **NSF fee charged to the merchant.** Typically $25-100 per bounce, applied to the next successful pull or accumulated as an end-of-deal fee.
4. **Bank-side NSF fee.** The merchant's own bank typically charges $30-40 per returned ACH. So a single bounce often costs $65-140 between the two sides.
5. **Default trigger threshold.** Most FRSAs define default as 3-5 consecutive bounced pulls within a rolling 14-30 day window — at which point acceleration, COJ filing, and collections begin.

**The mechanics — return codes that matter.** NACHA return codes the funder watches for:

- **R01 (Insufficient Funds).** Standard NSF. Default risk grows with frequency.
- **R02 (Account Closed).** Major red flag — often indicates the merchant has switched banks to evade pulls. Acceleration almost always follows.
- **R08 (Payment Stopped).** Stop-payment from merchant. Considered an intentional default; almost always triggers acceleration and litigation.
- **R10 (Unauthorized Debit).** Merchant has disputed the authorization with their bank. Funder must produce the signed authorization within 60 days or the chargeback stands. Repeated R10s prompt UCC and judgment enforcement.
- **R29 (Corporate Customer Advises Not Authorized).** Same effect as R10 on commercial accounts.

**The strategic insight — what merchants control.** Three operational levers:

1. **Maintain a buffer account.** Keep 5-10 business days of debits ($3-15K depending on deal size) as a floor in the operating account. Eliminates accidental NSFs from timing mismatches.
2. **Match pull timing to deposit patterns.** Most funders will move the pull from morning to afternoon (or vice versa) on request — useful if customer card-batch deposits land midday.
3. **Request a same-day reversal if a legitimate NSF was timing-only.** If the bounce was because a deposit landed an hour late, the funder can usually re-initiate same-day rather than waiting 2 days. This avoids the bounce hitting the default counter.

**The strategic insight — what merchants must NOT do.** Three actions that escalate from "bumpy" to "litigation" almost overnight:

1. **Stop payment on the ACH (R08).** Treated as intentional breach. Almost always triggers immediate acceleration and COJ.
2. **Close the account (R02).** Same — treated as evasive intent.
3. **Switch banks without disclosing.** The funder will eventually find the new account via UCC searches or processor data and serve a writ; meanwhile the missed pulls are racking up default counts.

**The honest framing.** ACH pull mechanics are the most boring and most consequential part of an MCA. Funders run their portfolios on bounce-rate signal — a clean, predictable pull pattern earns goodwill on renewals, reconciliations, and prepayment discounts. A choppy pull pattern marks the merchant as a workout file and changes every subsequent conversation. The merchant who treats the daily pull as a fixed operating expense — buffered, monitored, never blocked — preserves every form of leverage they have on the deal.

- [MCA bounce fee (NSF fee, returned ACH fee)](https://fundnode.co/llms/glossary/mca-bounce-fee) — Fee the funder charges when a daily ACH debit fails for insufficient funds — typically $25-$50 per bounce, on top of the merchant's bank NSF fee. Often triggers default review at 3+ bounces.
- [MCA ACH bounce fee](https://fundnode.co/llms/glossary/mca-ach-bounce-fee) — Fee charged by the funder when a scheduled daily ACH debit fails (R01 NSF / R09 uncollected) — typically $25-$50 per event, stacked on top of the merchant's bank NSF fee of $30-$45.
- [ACH pull stop payment MCA](https://fundnode.co/llms/glossary/ach-pull-stop-payment-mca) — When a merchant instructs their bank to block the funder's daily ACH debit — almost always an immediate breach triggering acceleration, COJ filing, and asset enforcement; legally permitted under Reg E but operationally catastrophic for the merchant.
- [Reconciliation (MCA)](https://fundnode.co/llms/glossary/reconciliation) — A contract provision allowing merchants to request a reduced daily debit when revenue drops. Required for MCAs to remain legally a 'sale,' not a 'loan' in most states.
