Stacking is the practice of taking a second merchant cash advance while a first MCA is still being repaid — meaning the business has two daily ACH withdrawals running simultaneously. It is one of the highest-risk capital structures in small business finance, and most direct funders (Westline included) decline to fund stacked positions.
The math is the problem. A single MCA at 12% of monthly deposits is sustainable. Two stacked MCAs at 12% each is 24% of revenue going to debt service before payroll, COGS, or rent. Most businesses can't survive that for the 6-12 months it takes to clear the stack.
Why Stacking Happens
Owners stack for predictable reasons:
- Revenue grew faster than expected, and they want more capital before the first advance pays off
- An emergency hit mid-advance — equipment break, lost contract, payroll gap
- Brokers pushed it. Stacking generates a second commission. Some brokers actively recommend it without showing the combined payment math.
- The first advance was already too tight, and a second was needed to cover the first
The fourth reason is the most dangerous. Stacking to cover an MCA payment is the financial equivalent of paying a credit card with another credit card — at 80%+ APR-equivalents.
The Combined Payment Math
Worked example. Business has $200K monthly deposits.
Single MCA: $50K advance at 1.30 factor, 6 months. Daily ACH ≈ $500. Monthly payment ≈ $11K (5.5% of revenue). Manageable.
Stacked second MCA: Add $30K advance at 1.40 factor (worse terms because of stacked risk), 6 months. Daily ACH ≈ $350. Combined daily ≈ $850. Combined monthly ≈ $18.7K (9.4% of revenue).
Stacked third MCA: Add $25K advance at 1.45 factor, 5 months. Daily ACH ≈ $325. Combined daily ≈ $1,175. Combined monthly ≈ $25.9K (13% of revenue).
For most businesses, 13% of gross revenue going to MCA service exceeds operating margin. Once the combined payment exceeds margin, the business is borrowing to cover its own debt service — which is mathematically unsustainable.
How Funders Detect Stacking
Three primary detection methods:
- UCC search. Active UCC-1 filings from other funders show in public records.
- Bank statement analysis. Daily ACH withdrawals to known funding companies are easy to spot. Underwriters look at last 90 days of statements.
- Funder syndicates. Several MCA funders share a stacking-detection database. A new application gets cross-referenced against active funded advances within minutes.
Why Most Direct Funders Decline Stacks
Risk pricing. A stacked merchant has 2-3x the default probability of a single-advance merchant. To make the math work, a funder either has to charge 1.50+ factor rates (which most legitimate funders won't) or simply decline. We decline.
If You're Already Stacked — How to Unwind
Three legitimate paths:
1. Consolidation refinance
A single new advance large enough to pay off all existing positions, replacing multiple daily payments with one. The new advance is usually at a higher factor rate than any of the originals (because the consolidated risk is greater), but the combined daily payment is much lower than the stack. This is the cleanest unwind for businesses with a path to recovery.
2. SBA refinance
SBA 7(a) loans can be used to refinance MCA debt at much lower APR (currently 11-13%). The qualification bar is high — 650+ FICO, 2+ years in business, full financials, 30-90 day timeline — but the savings are massive. A $200K MCA stack at blended 1.35 factor refinanced into a $200K SBA at 12% saves ~$50K over the life of the loan.
3. Settlement
If the stack is unrecoverable — combined payments exceed margin, business cash flow can't catch up — direct settlement with each funder is sometimes possible. Settlements typically range from 50-75 cents on the dollar for the remaining balance, paid in installments. This requires the merchant to be honest with funders about the situation, supported by financial documentation.
The Single Best Prevention
Don't stack. If a first MCA is too tight, the right move is to call the original funder and request reconciliation — not take a second advance. Reconciliation lowers the daily ACH without adding new debt. Stacking adds new debt at worse terms to address a problem the first funder might have solved for free.
