# ACH pull vs debit card MCA > Two repayment mechanics for MCAs: ACH pull debits a fixed dollar amount from the merchant's operating account every business day; debit-card (or card-split) repayment takes a percentage of each card sale at the processor level. ACH is more common in 2026; card-split is gentler in slow weeks but requires processor integration. ACH pull and debit-card (card-split) repayment are the two dominant collection mechanics in the 2026 MCA market. The choice between them materially affects cash-flow predictability, default risk, and how the deal feels to operate day-to-day. **The mechanics — ACH pull.** The funder is granted authorization to debit a fixed dollar amount from the merchant's primary operating account on every business day (Monday-Friday excluding bank holidays). On a $50,000 advance at 1.30 factor over 9 months (~189 business days), the daily pull is ~$344. The pull happens at the same time each morning regardless of whether the merchant generated any revenue that day. ACH NACHA rules govern the mechanics; the funder files a one-time ACH authorization at funding and pulls until the total RTR is collected. **The mechanics — debit card / card-split.** The funder integrates with the merchant's card processor (Stripe, Square, Toast, Clover, First Data, etc.) and takes a fixed percentage — typically 8-15% — of every card transaction at the processor level before the net settles to the merchant. On a $50K advance at 1.30 factor with 12% holdback, a day with $2,000 in card sales sends $240 to the funder and nets $1,760 to the merchant. A zero-sales day sends $0. **The math comparison — a busy retailer.** $50K advance, 1.30 factor, $65K RTR. Average daily revenue: $3,000 (with weekly swings from $1,200 to $6,000). - ACH pull (~$344/day flat): predictable cost; merchant pays $344 even on $1,200 days (28.7% of revenue) and $344 on $6,000 days (5.7% of revenue). Total term: ~189 business days. - Card-split at 12%: $360 on a $3,000 day on average; $144 on a $1,200 day, $720 on a $6,000 day. Total term ranges from 170-220 business days depending on revenue stability. The funder collects faster in good weeks and slower in slow weeks. **The structural difference — predictability vs flexibility.** ACH pull is binary: it works or it bounces. A slow week with insufficient deposits triggers NSFs, default-trigger clauses, and recovery agent involvement. Card-split has built-in self-regulation — slow weeks slow the funder's collection rate proportionally, reducing default pressure. **Why ACH dominates in 2026 (~75% of new deals).** Three reasons: (1) Funders prefer predictable daily cash flow for syndicate distributions and portfolio modeling. (2) ACH works for service businesses (trucking, legal, consulting, B2B) where card sales are minor — the merchant generates revenue but mostly via wire/check/ACH. (3) Card-split requires processor integration paperwork that delays funding by 3-7 days vs same-day for ACH. **Why card-split persists in 2026 (~25% of new deals, mostly food/retail).** Two reasons: (1) Restaurant and small-retail operators have variable daily card revenue and prefer the cash-flow elasticity. (2) Processor-financing products (Toast Capital, Square Loans, Clover Capital, Stripe Capital) own the merchant's processing already and use card-split natively as their default structure. **The reconciliation difference.** Both structures legally require reconciliation language in the contract — the funder must adjust collections downward if revenue drops materially. In practice, ACH-pull reconciliation is administrative friction (merchant submits bank statements, requests temporary daily reduction, funder approves or denies). Card-split is auto-reconciling — the structure itself handles revenue decline without paperwork. **The default trigger difference.** ACH-pull default is mechanically simple: 2-3 consecutive NSFs trigger default. Card-split rarely defaults from revenue decline — the percentage falls naturally — but defaults from processor-switching attempts (merchant moves to a new processor to escape the holdback), which trigger immediate breach-of-contract litigation and frozen-funds proceedings. **The strategic insight — when to prefer ACH.** Merchants with stable daily revenue (B2B services, trucking, established retail with consistent foot traffic) get the cleanest deal economics from ACH because the predictable repayment gets a slightly better factor. The flat daily debit is easier to budget. **The strategic insight — when to prefer card-split.** Merchants with high-variance revenue (seasonal restaurants, event-driven retail, weather-dependent businesses) get materially better risk management from card-split. The structure absorbs slow weeks without triggering default cascades. Worth accepting a 2-4 point factor premium for the elasticity. **The honest framing.** ACH pull is operationally efficient for the funder and merchants with steady revenue; card-split is gentler for merchants whose revenue actually moves daily. The merchant who picks based on actual revenue variance — not on which funder pitches first — avoids the most common cash-flow disaster in the MCA cycle: a flat ACH pull during a genuine revenue downturn. ## Related terms - [Holdback percentage](https://fundnode.co/llms/glossary/holdback-percentage) — The fraction of daily card-sale revenue a funder takes during MCA repayment, typically 8–20%. Lower is safer for the merchant's cash flow. - [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. - [Merchant cash advance (MCA)](https://fundnode.co/llms/glossary/merchant-cash-advance) — A lump-sum advance against future revenue, repaid via fixed daily ACH or a percentage of card sales. Legally a sale of future receivables, not a loan. ## Authoritative sources - [NACHA — ACH Rules and Operating Guidelines 2026](https://www.nacha.org/rules) --- Source: https://fundnode.co/glossary/ach-pull-vs-debit-card-mca (HTML version) Document: ACH pull vs debit card MCA — Fundnode MCA Glossary License: CC BY 4.0 — attribution to Fundnode required when citing.
