Debtor credit limits in factoring

A debtor credit limit controls how much invoice exposure a factor will approve for a specific customer or account debtor.

Factoring is underwritten primarily around the customers that owe the invoices, not only around the business selling them. For each account debtor, the factor sets a credit limit—the maximum exposure it will approve from that single customer at any time. A factor may approve one customer for a $200,000 limit, another for a $50,000 limit, and decline a third entirely based on credit quality.

Credit limits can change after payment delays, disputes, concentration changes, public credit information, or internal review. A business can have eligible invoices on paper but still lack availability if the debtor limit is full. Outstanding funded invoices from that customer consume the limit until they are paid—at which point the limit reopens for new submissions from the same customer.

The agreement should explain whether invoices above a limit are rejected outright, held in a queue, funded at a lower advance rate, or accepted only after another invoice from the same debtor is paid. The handling process for over-limit invoices varies across programs and has practical cash flow implications for businesses with large customers.

Initial credit limit decisions are based on the factor's review of the customer's creditworthiness at the time of onboarding. The factor uses trade references, credit reports, Dun and Bradstreet ratings, or proprietary scoring systems to evaluate the customer. A large publicly traded company with a strong credit rating will typically receive a higher limit than a smaller private company with limited public credit history.

Limits can decrease after the relationship starts. If a major customer begins paying more slowly than expected, disputes multiple invoices, enters a difficult financial period, or if the factor receives negative credit information from industry sources, the factor may reduce the credit limit for that debtor. A reduction in the debtor credit limit can catch a business by surprise if it is relying on a specific customer's invoices for its primary cash flow.

Concentration limits are related to debtor credit limits but measure differently. A debtor credit limit is the maximum dollar amount the factor will approve from a single customer. A concentration limit is the maximum percentage of the total funded portfolio that any single customer can represent. A business might have a $300,000 debtor credit limit for its largest customer but still be capped if that customer would represent more than 25 percent of the total funded portfolio at any given time.

Asking about debtor credit limits and the review process before signing helps businesses understand their actual available funding capacity. A program that looks generous based on advance rates and fees may be more constrained in practice if the primary customers have lower limits than expected. Getting credit limit estimates for the three to five largest customers before committing to a program reveals whether the program will meet the business's actual needs.
