Direct answer
A borrowing base starts with eligible invoices, then subtracts exclusions, reserves and existing draws.
A current receivables aging, customer contract, actual invoice and proof of accepted goods or services show what the buyer owes. Eligibility is assessed on the actual transaction rather than a general claim that a business has sales.
How to assess this transaction
Apply the proposed advance rate only to balances that meet the lender's rules.
Trace the cash cycle from invoice issue, buyer approval, any advance, collection and release of the remaining balance. Identify which obligation falls due before the buyer pays and whether that stage has supporting records.
Where applications run into trouble
Ledger total is not equal to cash available to draw.
Put this risk in writing when comparing proposals. Ask which part of the order or receivable would be excluded and whether approval depends on a document you have not yet obtained.
Practical next step
Gather the documents for one real transaction and ask National Invoice Factoring which parts can be reviewed. Share the expected payment date and existing lender arrangements so any quote reflects your situation.
For broader context, review accounts receivable financing alongside alternatives; no article can determine approval or pricing for an individual deal.
