A merchant cash advance (MCA) for a retail business is a lump-sum advance against future credit and debit card sales, repaid via a fixed percentage of daily card batches until a predetermined total amount (the purchased amount) is collected. Approval is based primarily on card processing volume, not personal credit score, making it accessible to retailers with thin credit files.
A merchant cash advance is not a loan — it is a purchase of future receivables. The MCA provider buys a portion of the retail business's future card sales at a discount, advancing the purchase price today and collecting the purchased amount via a daily or weekly holdback on card batches. For a cash-heavy retailer with strong card volume and a short-term capital need, an MCA can fund in 1–3 business days when conventional working capital products take weeks. Understanding the mechanics — especially the factor rate structure — is essential before signing.
MCA underwriters evaluate retail businesses on three primary signals: (1) Monthly card processing volume — most MCA programs require $10K+ per month in card batches; advance amounts are typically 75–150% of monthly card volume. (2) Consistency of card deposits — a retailer with steady daily card batches is lower risk than one with lumpy, irregular deposits; underwriters look for 6+ consecutive months of consistent processing. (3) Chargeback ratio — retail chargebacks (customer disputes processed through Visa/Mastercard) that exceed 1% of monthly volume signal dispute risk and may result in lower advance amounts or higher factor rates. Card sales are the collateral in an MCA — their predictability is everything to the underwriter.
MCAs operate entirely outside the SBA program framework. However, retailers currently using MCAs for working capital needs can often refinance out of MCA stacks into SBA-backed or bank working capital products at dramatically lower cost — if they meet SBA eligibility under 13 CFR Part 121 and have sufficient operating history. The SBA 7(a) program explicitly permits debt refinancing as an eligible use of proceeds, including refinancing high-cost short-term debt. A retailer paying 40–60% effective APR on MCA stacks who qualifies for a 7(a) working capital loan at 9–11% can save tens of thousands in annual financing cost. The tradeoff is the 30–90 day SBA processing timeline vs. same-week MCA funding.
Retailers should evaluate MCAs against three retail-specific realities: (1) Q4 seasonality — an MCA funded in October and repaid via daily holdback will collect heavily in November–December when card volume spikes, potentially clearing the full advance before year-end. This can work in the retailer's favor (fast payoff) but also means a high-sales month accelerates debt repayment at the expense of working capital at the very moment the retailer needs cash for restocking. (2) Holdback during slow months — post-holiday (January–March), card volume drops sharply; holdback continues at the same percentage, but smaller daily batches mean slower repayment and extended cost exposure. (3) Online vs. in-store card volume — retailers with growing e-commerce revenue process card sales through multiple gateways; not all gateways qualify for MCA holdback in every program. Retailers with split card volume across in-store terminals and Shopify should confirm which processing channels count toward the MCA repayment calculation.
A 1.35 factor rate sounds modest — but on a 6-month repayment, the effective APR is approximately 70%. On a 3-month repayment, it exceeds 140%. MCA providers are not required to disclose APR under most state laws, as MCAs are structured as commercial purchase-of-receivables transactions. Retailers comparing MCA offers should convert all quotes to effective APR for an apples-to-apples cost comparison. The CFPB has noted MCA disclosure gaps as a consumer and small-business protection concern.
