The choice between daily-ACH and weekly-ACH MCA payment structures is one of the few negotiable terms in MCA contracts — and it materially affects the operational stress the advance creates. Most merchants accept whichever structure the funder defaults to (almost always daily); the merchants who proactively request weekly often get it and benefit from it.
The mechanics — daily ACH. The funder debits the merchant's business checking account every business day (roughly 22 times per month — excludes weekends, federal holidays). A $130,000 total repayment over 9 months ÷ 195 business days = $667/day. The merchant sees the same dollar amount disappear from their account every business day at 6-8am Eastern.
The mechanics — weekly ACH. The funder debits once per week, typically on Mondays or Fridays. Same $130,000 over 9 months = 39 weeks = $3,333/week. The merchant sees a larger single hit four times a month, then nothing in between.
The math — same payback, different stress. Both structures collect the same $130K over the same 9 months. But the cash-flow patterns produce different operational outcomes:
Scenario A: Restaurant doing $60K/month revenue, fairly even daily distribution ($2K-$3K/day weekday, $4K-$5K Friday/Saturday). Daily ACH of $667 leaves comfortable daily cushion. Weekly ACH of $3,333 hitting Monday morning when only $2K came in over the weekend creates an immediate negative balance and NSF risk.
Scenario B: B2B services firm doing $60K/month from 4 large invoices (one per week, typically Thursday deposits). Daily ACH means 6 of 7 days have nothing coming in but $667 going out — Mon-Wed run negative until Thursday's deposit hits. Weekly ACH on Friday lets the merchant collect Thursday, pay Friday, breath until next week.
Scenario C: Trucking company doing $60K/month from broker payments (often 14-21 day terms, irregular deposits). Daily ACH whipsaws the account; weekly ACH stacks all the pressure on one day. Neither structure works well — this is where bi-weekly (every 14 days) becomes the right ask.
Funder economics — why daily dominates. Daily ACH wins ~85% of the MCA market because of funder-side benefits:
- Predictable cash flow for funders. Daily collection smooths funder revenue, simplifies capital management, supports securitization models (asset-backed lines of credit funders use require predictable collection streams).
- Earlier default detection. If the merchant's account goes NSF on Monday, the funder knows Monday. With weekly ACH, the funder doesn't see Monday's problem until Friday — five days of additional risk exposure.
- Faster collection of small amounts. When a merchant's account has only $400 available and the daily ACH is $667, the funder can collect the $400 and re-attempt the next day. Weekly ACH of $3,333 against a $400 balance is a full NSF — no partial collection possible.
- ISO commission timing. Commissions are paid on initial funding plus residual on collections. Daily debits create cleaner residual accounting for ISOs.
Merchant negotiation — when to ask for weekly. Three merchant profiles where weekly ACH is materially better and most funders will agree if asked:
- B2B businesses with weekly invoicing cycles. Match the debit cycle to the receivables cycle.
- Construction, trucking, services with irregular daily deposits. Smooth the merchant's cash flow rather than the funder's.
- Merchants with payroll cycles that conflict with daily ACH. A merchant who runs payroll Thursdays has $0 in the account Friday morning; daily ACH that Friday is high-NSF risk. Weekly ACH timed to Wednesday avoids the payroll collision.
The factor-rate tradeoff. Weekly ACH usually costs 2-5 factor points more than daily ACH for the same merchant. A 1.30 daily-ACH advance might become a 1.33 weekly-ACH advance. Funders justify this as a "risk premium" for the longer detection window between debits. The premium is real but usually worth paying for merchants whose cash flow is mismatched to daily debiting.
The bi-weekly and monthly options. Some funders offer bi-weekly (every 14 days, 26 collections per year) for an additional 3-5 factor point premium. Monthly ACH exists but is rare and expensive — typically only on advances above $250K with strong A-paper merchants, at 5-8 factor point premium. Monthly ACH closely resembles a term loan structure and is sometimes used to make MCA pricing compete against bank term loans.
The strategic insight. Default to asking for weekly ACH on the initial offer. Most ISOs and funders quote daily by habit; merchant request for weekly is treated as a negotiable preference and granted ~60% of the time without rate change, ~30% with a 2-3 point premium, ~10% declined. The 60% who get weekly without premium saved themselves significant operational stress for asking a single question. The merchants who never ask lose by default.
The honest framing: payment frequency is the most underweighted negotiable variable in MCA contracts. Merchants overweight the factor rate (which is largely set by paper grade and not negotiable) and underweight the payment structure (which is highly negotiable and impacts cash flow more than 2-3 factor points either way).

- Daily ACH debit (MCA) — A fixed-dollar daily withdrawal from the merchant's bank account during MCA repayment. The most common MCA repayment structure in 2026, distinct from card-sale split (holdback) structures.
- Daily debit MCA — Daily debit MCA repayment pulls a fixed dollar amount from the merchant's business bank account every business day via ACH until the total factor amount is collected. Most common repayment structure in 2026, replacing card-split funding.
- MCA payment schedule — An MCA payment schedule lists every scheduled ACH debit date and amount from disbursement through final payment. Most are flat daily debits Mon-Fri; some funders use weekly or percentage-of-revenue schedules. Always request the schedule in writing before signing.
- Holdback vs fixed payment (MCA repayment structures) — Holdback = funder takes a fixed % of daily card sales (varies with revenue). Fixed payment = funder debits the same dollar amount daily via ACH (doesn't flex with revenue).
