SBA 7(a) Q&A
Short answer
Yes, high customer concentration can be a significant concern and potentially jeopardize SBA 7(a) loan approval, as it poses a substantial risk to repayment ability.
Lenders assess the stability and diversity of a business's revenue streams. If a single customer accounts for a large percentage of revenue (e.g., 20% or more, and especially 50%), the business is highly vulnerable to losing that customer. This concentrated risk can make lenders hesitant to approve an SBA loan due to concerns about the business's long-term viability and ability to repay if that key customer departs or reduces their business.
A buyer applies for a $1.2 million loan to acquire a manufacturing company where 60% of its revenue comes from a single large client. The lender identifies this as a high risk, requiring strong mitigation plans or potentially denying the loan due to revenue concentration.
Insider move
Lenders deeply analyze customer concentration and its potential impact on cash flow. They look for mitigating factors like long-term contracts, strong relationships, or a credible plan to diversify the customer base. Without such mitigants, it's a major red flag.
