FCA-registered UK lender FRN 782472 ## What makes a debtor ledger attractive. A strong ledger is not just a high sales number. It is a pattern of clean invoices owed by customers that can be verified and usually pay. Written and reviewed by [Bjorn Laku](https://www.cashbookfinance.co.uk/bjorn-laku), Director & CMO.

Use this before applying. If the weak point is obvious, solve it before asking for terms. Judgement point #### Clear B2B debtors Invoices to established businesses are easier to fund than consumer sales or hard-to-verify customers. Judgement point #### Low dispute history A ledger with clean delivery evidence and few [credit notes](https://www.cashbookfinance.co.uk/insights/invoice-finance-glossary#term-credit-note) is more reliable than one with constant adjustments. Judgement point #### Repeatable payment behaviour Lenders care about whether the ledger performs month after month, not just the latest large invoice. Check eligibility · About 2–3 minutes, no credit search. ### Bring evidence, not optimism. ### A lender is testing collectability, not just invoice volume. A large ledger is not automatically a strong ledger. Quality comes from customers who can be identified, contacted and expected to pay against completed, evidenced work. Low dispute levels, consistent credit-note behaviour and a spread of established B2B debtors usually matter more than one impressive headline balance. Preparation should reconcile the [aged debt report](https://www.cashbookfinance.co.uk/insights/invoice-finance-glossary#term-aged-debt-report) to the accounting records, explain overdue items and separate [retentions](https://www.cashbookfinance.co.uk/insights/invoice-finance-glossary#term-retention), contra arrangements, related-party balances and invoices still subject to acceptance. That gives the lender a realistic view of what can be advanced and what should remain outside the facility. - Provide a current aged-debt report and top-debtor commentary. - Show contracts, invoices and proof of delivery for a representative sample. - Explain disputes, credits, concentrations and unusual payment patterns.

Illustrative review framework ### Cashbook Finance perspective When Cashbook Finance reviews a debtor ledger for invoice finance, size alone is not enough. We look for valid and evidenced invoices, debtor quality, payment behaviour, concentration, disputes, credit notes and reporting that reconciles to the underlying trade. A smaller, cleaner ledger can be more fundable than a larger ledger with weak evidence or concentrated risk. This reflects recurring factors in Cashbook Finance underwriting and case reviews. It is general information, not an approval promise or a substitute for assessment of a specific application. ### What “good ledger quality” actually means. A ledger is not attractive because it is large. It is attractive when the debts are valid, collectible, diversified enough and controlled by reliable reporting. 25 points #### Debtor quality Financial strength, payment history, sector exposure and whether the debtor can set off other claims. 20 points #### Concentration How much of the ledger depends on the largest debtor and whether that exposure is stable or rising. 20 points #### Invoice validity Completed work, contractual entitlement, delivery evidence, approval and absence of material dispute. 15 points #### Ageing Current balances, overdue trends, old debt and whether extensions are becoming normal. 10 points #### Dilution Credit notes, returns, rebates, contra, retentions and other reductions from invoice face value. 10 points #### Reporting control Ledger [reconciliation](https://www.cashbookfinance.co.uk/insights/invoice-finance-glossary#term-reconciliation), audit trail, collections discipline and the speed at which exceptions are identified.

A £150,000 sales ledger in which one customer owes £75,000, against a concentration limit of 40% of the ledger (£60,000). Spread, current and undisputed invoices are what make a ledger attractive; one dominant or slow customer reduces what can be drawn. Check eligibility · Talk it through with a director | Sales ledger (money customers owe you) | £150,000 | | --- | --- | | Less invoices over 90 days old | −£5,000 | | Less disputed invoices | −£3,000 | | Less the part of one customer above its concentration limit | −£15,000 | | Eligible ledger | £127,000 | | Available to draw at 85% | £107,950 | | Available if the ledger were all eligible | £127,500 | Illustrative: an 85% advance against eligible invoices. Eligibility rules, concentration limits and advance rates are set for each facility after review. ### Debtor ledger quality: use the comparison to make a funding decision. A strong ledger is evidenced, diversified and capable of converting into cash without avoidable disputes. #### Ageing Recent, undisputed balances are stronger than old or repeatedly promised debts. #### Concentration A dominant debtor can reduce availability or require a specific limit. #### Dilution Credit notes, offsets, returns and rebates reduce the amount likely to be collected.
