Invoice Finance for Accountants and FDs: Reading a Client's Ledger

Market Invoice is an independent UK invoice finance comparison site that ranks 89 UK invoice finance providers.

This page is for accountants and fractional FDs looking at a client's aged debtor listing and wondering whether invoice finance is the right instrument. It covers what in a ledger makes it fundable, what reduces the advance a client will actually receive, and what to tell a client before making an introduction. It is deliberately narrow: receivables only, not whole-of-market business finance.

Start with what is causing the gap

Invoice finance solves one problem well: cash tied up in invoices that have been raised for work already delivered. If the client's gap is settlement timing, and it grows when they win more work, the ledger is the right place to look. If the gap is caused by thin or negative gross margin, funding the ledger moves the problem forward rather than solving it, and a funder's underwriting will usually reach the same conclusion.

Read the ledger the way a funder will

The headline ledger value is rarely the fundable ledger value. Before making an introduction it is worth checking four things, because they are the four that move the advance rate most:

What clients are usually surprised by

In practice the terms that cause friction later are not the headline rate. They are whether the facility is disclosed to the client's customers or confidential, the notice period and minimum term that determine how expensive it is to leave, and the security package, which commonly includes a personal guarantee or an all-asset debenture and therefore interacts with anything already charged. The cost guide sets out how service and discount charges are built up, and confidential invoice discounting covers the disclosure question in full.

Scope of this page

This is a receivables page. Factoring, invoice discounting and selective invoice finance are in scope. Term lending, asset finance, commercial mortgages and merchant cash advances are not, and a client whose need is one of those is better served elsewhere. Market Invoice is a comparison and introducer service, not a lender.

Invoice finance suits a client whose working capital gap is caused by settlement timing on invoices already raised for delivered work, not by weak gross margin. More detail + scope

Summary

Guidance for accountants and fractional FDs assessing whether a client's aged debtor ledger suits invoice finance. Fundability is driven by debtor concentration, dilution (credit notes, short payments, write-offs), billing shape (stage billing, applications, retentions) and contra or intercompany balances, which together explain why the fundable ledger is smaller than the headline ledger.

Before an introduction, clients should understand whether the facility is disclosed or confidential, the notice period and minimum term, and the security package, which commonly includes a personal guarantee or an all-asset debenture. Scope is receivables only: factoring, invoice discounting and selective invoice finance.

Accountant and FD Referral FAQ

What in a client's ledger suggests invoice finance is worth exploring?

A working capital gap that is caused by settlement timing rather than by trading losses. Typically: invoices raised against delivered, undisputed work; customers who pay reliably but slowly; and a gap that widens as the client wins more work. Invoice finance advances against that ledger, so it scales with sales. It does not fix a business that is unprofitable at the gross margin line, and it is the wrong instrument for funding a loss.

What makes a ledger harder to fund?

Debtor concentration is the usual one: where a single customer is a large share of the ledger, most funders apply a concentration limit and will only advance against the portion inside it. Others are contra accounts (where the customer is also a supplier), stage or application billing, retentions, intercompany invoices, sales made on sale-or-return, and a history of credit notes. None of these are automatic refusals, but each reduces the advance a client will actually receive against the headline ledger value.

What is dilution and why do funders ask about it?

Dilution is the gap between what is invoiced and what is finally collected: credit notes, discounts, short payments and write-offs. A funder underwrites the ledger it will be repaid from, so a client with a clean invoice-to-cash record gets a better advance rate and fewer reserves than one with regular credit notes. It is worth checking in the client's own records before a referral, because it is one of the first things underwriting will test.

What should I tell a client before referring them?

Three things that clients are most often surprised by. First, whether the facility is disclosed or confidential, because that determines whether their customers are told. Second, the notice period and any minimum term, which is what makes a facility expensive to leave rather than expensive to run.

Third, that most facilities are supported by a personal guarantee or an all-asset debenture, which interacts with any existing security. See the guide to invoice finance costs for how the charges are actually built up.

Is this the same as a whole-of-market business finance referral?

No, and deliberately so. This page is about the receivables ledger only: factoring, invoice discounting and selective invoice finance. If a client's need is a term loan, asset finance, a commercial mortgage or a merchant cash advance, that is a different conversation and a different market, and this is not the right route for it.

How does the referral itself work?

Use the same form the rest of the site uses. Market Invoice is a comparison and introducer service, not a lender: we compare the market and introduce the client to providers whose criteria fit the ledger. There is no charge to the client for the comparison, and the client speaks to the provider directly.
