MCA stacking — the practice of a merchant having multiple active cash advances simultaneously — is one of the most controversial topics in the alternative lending space. It's common, it can be done responsibly, and it can also create serious problems for merchants and brokers who don't manage it carefully.

This guide explains what stacking is, when it works, when it doesn't, and how to handle existing positions when underwriting a deal.

What Is MCA Stacking?

Stacking occurs when a merchant has two or more active MCA or revenue-based advance positions running simultaneously. Each position has its own daily or weekly payment. A merchant with three stacked advances might be paying $800–$1,500 per day in combined debt service — a significant cash flow burden on a business with $30,000–$50,000 in monthly revenue.

Why Stacking Happens

Merchants stack for several reasons: they need more capital than a single advance covers, they took a small advance and then a business opportunity arose requiring more capital, or they're using a new advance to keep up with payments on an existing one (debt cycling — a serious red flag). Understanding why a merchant is stacking helps you assess risk.

When One or Two Positions Is Acceptable

A merchant with 1 existing advance is standard — most funders allow it and won't penalize the merchant's terms significantly. A merchant with 2 open positions is workable at many B and C-paper funders but not at most A-paper funders. The key metrics:

  • Total daily debt service should not exceed 15–20% of average daily revenue
  • The existing positions should be mid-term or later — not just funded
  • The new advance should bring the total to 2 positions max for most funders
  • The merchant should have a clear business reason for the additional capital — not just to cover existing payments

When Stacking Is a Red Flag

  • 3+ existing positions: this is almost always a debt spiral; most reputable funders will decline
  • Very new positions: if the existing advances were funded in the last 30 days, the merchant is cycling
  • Existing positions with default history: a bounce on one advance signals the merchant can't support their current payment load
  • No clear use of funds: 'I just need cash' is not a business reason when the existing positions indicate financial distress

How to Identify Stacking in Bank Statement Review

When reviewing bank statements, look for recurring daily or weekly ACH debits from companies whose names suggest lending or funding. Common patterns: 'RAPID ADVANCE,' 'GREENBOX CAPITAL,' 'LIBERTAS FUNDING,' or any daily fixed debit in the $150–$800 range that appears consistently. Count each distinct recurring debit series as a position.

When you identify stacks, calculate the daily debt service total and compare it to the average daily revenue. If combined debt service exceeds 20% of average daily revenue, the merchant likely can't support an additional position without financial distress.

Be transparent with your merchant about stacking. If they have 2 positions and you're adding a third, make sure they understand the total daily payment and that it's truly affordable. Submitting a deal that puts a merchant in financial distress hurts them, damages your funder relationships, and reflects on your professional reputation.

Funders' Stacking Policies

Each funder has a specific stacking policy. Some will fund position 1 or 2 only. Others allow up to 3 positions with the right deal profile. Some specialize in high-position deals but charge higher rates. Knowing each funder's policy is essential — submitting a 3-position deal to a 1-position-only funder wastes time and consumes a credit inquiry.

Bottom Line

MCA stacking is a reality in the alternative lending market. Your job as a broker is to identify it, assess whether the merchant can genuinely support the additional debt service, and only submit to funders whose policies match the position count. Responsible stacking helps merchants who have real capital needs. Irresponsible stacking puts merchants in debt spirals and destroys relationships. Know the difference and act accordingly.
