How to detect MCA stacking

Stacking is the risk that quietly sinks a deal: an advance funded on top of advances the merchant is already repaying. It’s all there in the daily-debit pattern — if you total it up.

A position shows up as a fixed ACH debit on a daily or weekly cadence.
Stacking is multiple such debits to different funders on one account.
Total combined daily debits and compare them to daily deposits.
Check every account and a full 3–6 months to catch hidden positions.

What stacking is — and why it matters

Stacking is taking a new merchant cash advance while one or more advances are still being repaid. Each position pulls its own fixed debit from the account, so stacking means several funders are all drawing from the same daily receipts. Fund into a heavily stacked merchant and you’re often the position that tips daily debits past daily income — the point where NSFs start and the whole stack defaults.

The signature of a position

An existing advance leaves a distinct fingerprint on the statement:

A fixed amount — the same dollar figure each time, e.g. $487.50.
A fixed cadence — every business day, or the same weekday each week.
An ACH descriptor naming a funder, a servicer, or a generic “daily ACH”.

One such debit is one position. When you see two or three different fixed debits — different amounts, different funder names, all recurring — that’s stacking.

Do the math that actually decides it

Detection isn’t just spotting the debits; it’s totaling them. Add up the combined daily remittance across every position and set it beside the merchant’s average daily deposits:

One advance at $500/day is noticeable. Two at $500 and $400 means $900 comes off the top before payroll or rent. A third pushes past $1,500/day — and if daily deposits average $1,800, there is almost no room left for a new position.

When combined debits approach a large share of daily deposits, expect the NSFs and negative days that come with an over-stacked account — and price or decline accordingly.

Where positions hide

A second bank account. A merchant may run advances out of one account and submit statements from another. Ask for — and read — every account.
Timing. An application filed just before debits post can look clean. A full 3–6 month history closes that gap.
Disguised descriptors. Some debits read as generic ACH rather than a funder name. The fixed amount and cadence still give them away.
The disbursal side. A recent advance often lands as a large credit — which also inflates gross deposits. Catching the disbursal both fixes revenue and confirms a position.

Detection, done automatically. mcaunderwriting.com groups recurring debits by amount and cadence, matches descriptors against a maintained list of known MCA funders, and reports each detected position with funder, amount and cadence — plus fixed monthly obligations flagged as candidates for you to confirm. It also strips known advance disbursals out of revenue, so a prior funding can’t masquerade as sales.

Detecting positions is one step of the full read — see how MCA underwriting works and how to read a bank statement for MCA for the rest.

Frequently asked questions

What does MCA stacking look like on a bank statement?

Multiple fixed ACH debits, each on a daily or weekly cadence, going to different funders or servicers. One position is a single recurring debit; stacking is two, three or more of them hitting the same account.

Why is stacking risky to fund into?

Each position takes its cut off the top of daily receipts. When combined daily debits approach or exceed daily deposits, the merchant can’t sustain them — leading to NSFs, negative days and default. A new advance on top often triggers the collapse.

Can a merchant hide existing positions?

Sometimes — by funding from a second bank account and submitting statements from a different one, or by timing the application before debits post. Reviewing all accounts and a full 3–6 months, and cross-checking deposits against known advance disbursals, is how you catch it.
