Funding mechanics

Invoice finance: the questions behind the advance

Use your ledger to test a facility: eligible debt, concentration, costs, customer contact and the effect of late payment.

Quick answer

What should you ask an invoice finance provider to demonstrate?

Ask for an availability calculation using a representative ledger and a cost illustration for both normal and slower payment. It should show ineligible debt, concentration limits, the advance, charges and what happens when an invoice becomes disputed or overdue.

Key points

  • Choose a representative ledger, not just the strongest month.
  • Reconcile the ledger total to eligible debt and actual availability.
  • Test a late major customer separately.
  • Agree who owns the daily administration.

Choose a ledger that represents normal trading

Export an aged-debtor summary for a useful date and note unusual items. Separate current invoices, overdue balances, disputes and credit notes. Explain which customers account for the largest amounts and how their actual payment patterns compare with the terms printed on the invoice.

Before sharing customer-level data, agree a secure route and establish what the provider needs. You can begin the discussion with a summary of values, ages and concentration. The purpose of the exercise is to understand the facility’s mechanics on your business, not to distribute the full ledger to every provider at once.

Ask for the availability bridge

Start with the ledger total, remove each category the proposed provider excludes, apply any debtor limits, then calculate the eligible advance. Finally deduct existing drawings or other adjustments. Request the result in a format you can repeat after the facility starts.

The British Business Bank explains that provider eligibility and the quality of receivables affect invoice finance [1]. For your comparison, the important step is making those rules explicit. An impressive advance percentage is less useful when the corresponding eligible balance is unclear.

Run a major-customer delay scenario

Take the largest customer and move its expected payment date later in the forecast. Ask the provider when eligibility changes and whether the business would need to repay an advance or supply replacement debt. Put that event on the same calendar as wages and supplier bills.

For illustration, an eligible balance of £60,000 at an assumed 80% advance produces £48,000 before other adjustments. Removing a £15,000 customer balance reduces that calculation to £36,000. The £12,000 difference is a timing problem to understand, not evidence of a provider’s actual terms.

Compare service as well as finance charges

Ask which party chases customers, handles allocation questions and resolves disputed invoices. Factoring and discounting can involve different administrative roles [1]. Price the arrangement you actually need rather than assuming the service with the lowest fee has the same workload.

Agree who in your company checks availability, sends credit notes and reconciles the provider account. Ask for a demonstration of the reporting process and establish which exceptions require a person. A facility that fits the ledger still needs to fit the team operating it.

Write down the exit process

Before signing, ask about notice, minimum terms, termination costs and how assigned debts or collections are released at the end. If you are replacing an existing facility, coordinate the settlement and customer payment arrangements with both providers.

Keep these questions in the same comparison as the advance and normal fees. A useful long-term facility should be understandable when it starts, while it runs and when the business needs to change it. Use our product page for a fuller explanation of the funding structure.

Frequently asked questions

Straight answers

Why might availability fall while sales grow?

Eligibility deductions, concentration limits, disputes or existing drawings can change the available balance. Ask for a reconciliation.

Should I compare one month or several?

Use a representative period and add scenarios that expose your business’s seasonality or large customer dependence.

Do I still need credit control?

The tasks depend on the facility. Agree the split of responsibilities in writing.
