MCA Stacking Detection in Underwriting
Identify whether a business already has active advances by spotting competitors’ recurring ACH debits in its bank statements — so you know about existing positions before approving a new deal.
What is MCA stacking?
Stacking is when a merchant takes a new cash advance while still repaying one or more existing advances. Each funder typically collects daily or weekly via ACH, so multiple advances mean multiple withdrawals draining the same account. Stacking raises default risk sharply: the combined holdback can exceed what the business’s cash flow can support, putting every position — including yours — at risk.
Why stacking is a funding risk
A deal that looks affordable in isolation can be unfundable once existing advances are counted. If you fund without seeing the other positions, you may be lending into an account that’s already over-committed, where your repayments compete with several others for the same deposits. Detecting stacking before you fund is what keeps a clean-looking deal from becoming an immediate loss — and it works hand in hand with cash flow and affordability analysis.
How stacking detection works
Existing advances leave a footprint in the bank statements: recurring debits, usually daily or weekly, with descriptors tied to the collecting funder. Stacking detection works by:
- Extracting recurring debits from the merchant’s statements (the bank statement analysis step).
- Matching those debits against a list of known competitor ACH descriptors.
- Flagging likely positions — the recurring outflows that match a competitor pattern — for the underwriter to confirm.
The signal is the combination of regularity (same amount, steady cadence) and a descriptor that matches a known funder.
Automating it with a configurable descriptor list
The hard part of doing this manually is knowing every competitor’s ACH descriptor and scanning months of transactions for them. MCA Verify automates the scan and lets each funder maintain its own configurable list of competitor descriptors — so detection reflects who actually operates in your market and improves as you add to the list. Recurring debits are matched automatically and surfaced for review, rather than relying on an underwriter to catch them by eye. It’s one piece of automated MCA underwriting.
Catch stacking before you fund
MCA Verify scans extracted recurring debits against your configurable competitor list and flags likely existing advances automatically.
