How are disputed or overdue invoices treated by lenders?

In UK invoice finance, disputed and overdue invoices are excluded from the funded debtor book. The invoice finance provider advances cash against eligible invoices only: undisputed, within agreed terms (usually 30 to 90 days from issue), to credit-approved debtors. Disputed invoices are typically removed from the funded balance until the dispute is resolved.

Three behaviours dominate. First, dispute notification: when your customer raises a query, the invoice is flagged on the funder's ledger and the advance against it is rolled back. Second, recourse versus non-recourse: in a recourse facility (the UK norm for SMBs), if an invoice goes unpaid past a defined period (typically 90 days past due), the funder claws back the advance. In non-recourse, the funder absorbs the loss but charges a higher fee for the credit insurance. Third, ageing: most facilities cap funding at invoices under 90 days from issue. Anything older drops out of the funded balance automatically.

For unsecured term lenders looking at your trading history, the relevant question is the pattern: occasional overdue invoices in a healthy debtor book are normal and ignored. A consistent ageing tail, repeat disputes, or a single concentrated debtor with poor payment history will reduce your effective borrowing capacity because lenders model debtor concentration risk into affordability.
