What a receivables finance audit checks, and what it can't
An audit tests whether the ledger you are funding is real, collectable and yours. It does that by sampling, which is powerful and has limits. Knowing both is how you get value from the report.

A financier lends against a sales ledger it doesn’t keep. Every month the client sends an aged debtors report, a schedule of new invoices and a note of cash received, and the financier advances against what those papers say. The audit is the moment someone checks the papers against the business that produced them.
That is all an audit is, and it is a great deal. It is worth being clear about what it covers, and about what it cannot tell you, before the report lands.
The ledgers
The starting point is the sales ledger itself. Does the aged debtors report agree to the ledger it was printed from, and to the debtors figure in the management accounts? Are the customers on it the ones you have been told about? Are the ageing settings the same as last month?
The purchase ledger matters almost as much. It shows who the client owes, how far behind it is with suppliers, and whether any supplier is also a customer: a contra.
The debtors
An auditor looks at the largest customers in detail. That means concentration against your limits, payment patterns, balances that have stopped moving, and credit notes. For a sample of invoices, the auditor goes further and asks for the paperwork behind each one: the order, the delivery note or timesheet, and the proof the work was done.
This is where most findings come from. An invoice raised before the goods left the warehouse, or a delivery short of what was billed, shows up in the paperwork long before it shows up in a missed payment.
The bank
Bank statements show what actually happened to the money. They show whether customers’ payments reached the account you control or the client’s own, how often the client’s account is overdrawn, and whether the overdraft ever clears. They also show who the client is paying, which can be more revealing than the ledger.
The Crown
PAYE, VAT and corporation tax arrears are an early warning. HMRC has ways to collect that can come ahead of other creditors, and a business falling behind with HMRC is usually falling behind elsewhere. The audit checks what is owed against when it was due, and asks about any time-to-pay arrangement.
What a sample can prove
An audit doesn’t check every invoice. It checks a sample, chosen so that the largest balances and the riskiest customers are covered. A clean sample is good evidence that the process behind the ledger works. A sample with problems is stronger evidence, because each problem found suggests others not looked at.
A clean sample tells you the process works. A failed sample tells you where to look next.
What a sample cannot do is prove a negative. “No pre-invoicing found in 25 invoices” is a finding about those 25. It is not a guarantee about the other 400. The report should say how the sample was drawn, so you can judge how far it reaches.
What an audit can’t tell you
An audit is a view of one day, built from documents the client provides. A determined fraud can produce convincing paperwork for a short time. An audit makes that harder and much more likely to be noticed, but it is not a substitute for watching the ledger between visits.
Nor does an audit predict whether a customer will pay. It can tell you that a customer is slow, disputes invoices or has stopped paying the old ones. Whether that customer is about to fail is a credit question, and the audit gives you the facts to ask it.
What to do with the findings
A good report separates what was found from what it means, and ranks the issues. Read the summary of issues first, then go to the section behind any issue that changes how you would fund the client.
Every finding needs an owner and a date. The most common failure is not a missed issue but a recorded one that nobody followed up, so the next audit finds it again. Turn each recommendation into an action with a name beside it, and ask about it at the next client review rather than at the next audit.
Questions to ask before you book
- What has changed since the last audit: new customers, new products, a new system?
- Which debtors are you most exposed to, and what do you already know about them?
- Is there anything specific you want tested, such as a customer you are unsure of?
- Which kind of audit fits: on-site, remote or desktop review?
The more the auditor knows before the visit, the more of the visit goes on the questions that matter to you. A short note of your concerns, sent with the booking, is often the most useful document the auditor receives.
