MCA Red Flags: 15 Things Underwriters Look for Before Funding a Merchant
MCA Red Flags: 15 Things Underwriters Look for Before Funding a Merchant
In merchant cash advance, speed matters.
Brokers want to move deals quickly. Funders want to make informed decisions quickly. Merchants want access to capital without unnecessary delays.
But moving quickly shouldn't mean overlooking important details.
A merchant's bank statements can contain a tremendous amount of information about the health of a business - from revenue trends and cash flow to NSF activity, existing obligations, and potential stacking.
The challenge is identifying the important signals before a deal gets submitted.
Here are 15 MCA red flags that brokers, ISOs, and underwriters should look for before funding a merchant.
1. Excessive NSFs
Non-sufficient funds (NSFs) can be an important warning signal.
Occasional NSF activity doesn't necessarily mean a business is unhealthy. However, frequent or increasing NSFs may indicate that the merchant is struggling to manage its available cash.
Underwriters should look at:
- How many NSFs occurred
- Whether they are increasing or decreasing
- When they occurred
- Whether they coincide with other cash-flow problems
- Whether the business recovered afterward
The trend can be more informative than a single NSF.
2. Frequent Negative Balances
Negative balances deserve attention.
If a business repeatedly falls below $0, it may indicate that cash leaving the account is consistently exceeding available liquidity.
Look at both the frequency and duration of negative balances.
A single brief negative balance may tell you very little.
Repeated negative balances throughout several months can tell a very different story.
3. Declining Revenue
Revenue isn't just about how much money comes into an account.
The direction of revenue matters.
A merchant generating $100,000 per month but steadily declining from $130,000 to $115,000 to $100,000 may present a different risk profile than a merchant consistently generating $100,000.
Underwriters should examine:
- Monthly deposits
- Revenue trends
- Consistency
- Seasonality
- Unusual fluctuations
A declining trend can be particularly important when combined with other risk indicators.
4. Heavy Existing Obligations
One of the biggest questions in MCA underwriting is:
How much of the merchant's existing cash flow is already committed?
Existing MCA and ACH obligations can significantly affect available cash flow.
Before approving additional funding, underwriters should identify existing obligations and understand the merchant's current payment burden.
The merchant may generate substantial revenue - but if too much of that revenue is already committed, additional financing could create significant pressure.
5. Multiple ACH Withdrawals
Multiple recurring ACH withdrawals can help reveal existing financing relationships.
When reviewing bank statements, underwriters should pay attention to recurring withdrawals that could represent:
- MCA payments
- Business loans
- Other financing obligations
- Equipment financing
- Other recurring commitments
Identifying these obligations helps create a more complete picture of the merchant's financial position.
6. Potential Stacking
Stacking is a major consideration in MCA underwriting.
A merchant may have multiple financing positions simultaneously, potentially increasing their total daily or weekly payment burden.
Underwriters should look for patterns suggesting multiple active positions and investigate them further.
Important: A transaction pattern alone isn't necessarily proof of stacking. It should be evaluated alongside the merchant's documentation and the overall deal context.
7. Unusual Deposits
Not every deposit represents ordinary business revenue.
Bank statements can contain:
- Transfers between accounts
- Loans
- Capital contributions
- Large one-time deposits
- Refunds
- Other non-operating transactions
Simply adding up deposits without understanding their source can create an inaccurate picture of revenue.
Underwriters should distinguish true operating revenue from non-revenue deposits whenever possible.
8. Excessive Transfers
Transfers between accounts can complicate revenue analysis.
For example, money transferred from one business account to another may appear to be a new deposit even though no new revenue was generated.
This is why gross deposits shouldn't automatically be treated as gross revenue.
Understanding transaction patterns can help prevent overstating the merchant's actual business activity.
9. Revenue Concentration
Where revenue comes from can matter just as much as how much revenue exists.
A business heavily dependent on a small number of customers, payment processors, or revenue sources may have different risk characteristics than a business with a more diversified customer base.
Underwriters should investigate unusual concentrations when they appear in the statements.
10. Irregular Cash Flow
Healthy businesses don't necessarily have perfectly consistent cash flow.
Seasonality is normal in many industries.
However, significant unexplained fluctuations can warrant additional investigation.
Look for:
- Large gaps between deposits
- Sudden spikes
- Sudden drops
- Highly inconsistent balances
- Changes in transaction activity
The goal isn't to automatically reject unusual activity.
It's to understand it.
11. High Payment Burden
Perhaps one of the most important questions is:
Can the merchant reasonably handle another payment obligation?
A merchant may have strong revenue but still have limited available cash flow after existing obligations.
Underwriters should consider the relationship between:
Revenue → existing obligations → available cash flow → proposed new payment
The bigger the existing payment burden, the more carefully a new position should be evaluated.
12. Insufficient Liquidity
Revenue isn't the same thing as liquidity.
A business can generate significant monthly revenue while maintaining very little cash available.
Ending balances, average balances, negative balance activity, and cash-flow patterns can provide additional context.
Liquidity can become especially important when evaluating the merchant's ability to absorb unexpected expenses or changes in revenue.
13. Recent Business Deterioration
One of the most important things an underwriter can do is compare recent performance with historical performance.
A merchant may have looked excellent several months ago but deteriorated recently.
Look for:
- Declining deposits
- Increasing NSFs
- Lower ending balances
- Increasing obligations
- Reduced transaction activity
- Increasing cash-flow volatility
Recent deterioration can sometimes be more relevant than older historical performance.
14. Incomplete Documentation
Sometimes the biggest red flag is simply missing information.
Incomplete documentation can make it difficult to properly evaluate a deal.
Depending on the funder's requirements, this might include missing bank statements, unclear ownership information, incomplete applications, or other documentation necessary for underwriting.
If something important is missing, don't simply guess.
Get the information.
15. Inconsistent Application Information
Finally, compare the application against the financial statements.
Does the stated revenue make sense?
Does the business activity reflected in the bank statements match the application?
Are there discrepancies that need clarification?
Inconsistencies don't automatically mean fraud or misconduct - but they do deserve investigation.
Good underwriting isn't about assuming the worst.
It's about verifying the facts.
The Bigger Picture: Red Flags Should Be Viewed Together
One of the biggest mistakes in underwriting is treating individual indicators in isolation.
For example:
One NSF doesn't automatically mean a bad deal.
One unusual deposit doesn't automatically mean a bad deal.
One existing position doesn't automatically mean a bad deal.
The real value comes from looking at the entire financial picture.
Consider a hypothetical merchant with:
- Declining revenue
- Frequent NSFs
- Multiple ACH withdrawals
- Increasing negative balances
- Several existing positions
- Limited liquidity
Each factor matters individually.
Together, they paint a much clearer picture of the overall deal.
That's why effective underwriting requires both data and context.
How AI Can Help With MCA Underwriting
Traditionally, analyzing several months of bank statements can require significant manual effort.
An underwriter may need to identify revenue, calculate trends, locate NSFs, identify recurring obligations, examine cash flow, and look for potential risk indicators - all while trying to move quickly.
AI can help organize that information.
FundingBrother.com is built specifically around this workflow.
MCA brokers and funders can upload merchant bank statements and receive structured underwriting intelligence, including:
Revenue Analysis
Identify monthly deposits, revenue trends, volatility, and consistency.
Cash Flow Analysis
Review average balances, ending balances, available cash flow, and unusual activity.
NSF Detection
Surface NSF activity, negative balances, and related patterns.
Existing Position Analysis
Identify potential MCA/ACH obligations and payment burdens.
Risk Flags
Highlight potential concerns that deserve additional attention.
Deal Scoring
Generate a 0-100 deal score designed to provide a quick snapshot of overall deal health.
AI Underwriting Copilot
Ask deal-specific questions and get answers grounded in the analysis.
The objective isn't to replace experienced underwriters.
It's to give them better information, faster.
AI Doesn't Replace Underwriting Judgment
This distinction is important.
AI should be treated as an underwriting assistant, not an autonomous approval engine.
An experienced underwriter still needs to consider:
- The merchant's industry
- Business circumstances
- Documentation
- Funder-specific guidelines
- Deal structure
- Context behind unusual transactions
- Information that may not appear in bank statements
AI can help surface patterns.
Humans still make the judgment.
A Faster Way to Review MCA Deals
The future of MCA underwriting isn't necessarily about choosing between humans and technology.
It's about combining the two.
The best workflow may look something like:
Merchant submits documents → AI analyzes the statements → potential risks are surfaced → broker/underwriter reviews the findings → questions are investigated → deal moves forward.
Instead of spending valuable time manually searching through statements for every possible signal, the underwriter can start with a structured view of the deal and focus their attention where it matters most.
Final Takeaway
MCA underwriting comes down to understanding the merchant's financial picture.
The strongest underwriters aren't simply looking for reasons to approve or decline.
They're asking:
What's actually happening inside this business?
Are revenues stable?
Is cash flow healthy?
Are existing obligations manageable?
Are there signs of stacking?
Are NSFs increasing?
Is the merchant maintaining adequate liquidity?
And perhaps most importantly:
Does the entire story make sense?
Technology can make finding those answers significantly faster.
That's the idea behind FundingBrother.com: turn raw bank statements into actionable underwriting intelligence so MCA brokers and funders can analyze smarter and move faster.

Frequently Asked Questions
What are MCA underwriting red flags?
MCA underwriting red flags are financial patterns or inconsistencies that may warrant additional investigation before funding a merchant. Examples include excessive NSFs, declining revenue, frequent negative balances, heavy existing obligations, potential stacking, and insufficient liquidity.
Does one NSF automatically mean a merchant should be declined?
No. Individual indicators should generally be considered within the broader financial context. Frequency, timing, trends, and the presence of other risk factors can be more informative than a single transaction.
What is stacking in MCA?
MCA stacking generally refers to a merchant taking on multiple financing positions, potentially increasing their overall payment burden. Transaction patterns can indicate potential stacking, but they should be verified against available documentation.
Why are existing MCA positions important?
Existing positions can affect the amount of cash flow available to service another obligation. Understanding existing payment commitments is therefore an important part of evaluating a new deal.
Can AI perform MCA underwriting?
AI can assist with analyzing bank statements, identifying patterns, organizing financial information, and surfacing potential risk indicators. However, AI analysis should complement - not necessarily replace - experienced underwriting judgment and funder-specific requirements.
