Invoice Discounting: How It Works, Costs and Who It Suits

What Is Invoice Discounting?

Invoice discounting lets you borrow against invoices your customers have not paid yet. You raise the invoice as normal, the provider advances most of its value within a day or so, and you carry on chasing the payment yourself. When the money arrives, the provider takes back what it lent plus its charges and releases the balance to you.

The British Business Bank describes it as a finance-only product: the lender funds your sales ledger and leaves the collections work where it was. That is the whole distinction from factoring, and it is also the condition attached to the lower price. A discounting facility costs less because the provider is not running your credit control. If your collections are already slow, you are buying a cheaper facility that depends on the thing your business is worst at.

Many facilities are also undisclosed, which means your customer is never told a lender is involved. Many, not all. Disclosed invoice discounting exists, and in most agreements confidentiality is a term the provider grants rather than a permanent feature of the product. We checked that against the British Business Bank’s own wording, which says many discounting facilities are undisclosed rather than all of them.

What Invoice Discounting Costs

Two charges do most of the work, and a tail of smaller fees decides which quote is actually cheapest. The service charge is a percentage of your turnover for running the facility. The discount charge is interest on the money you have drawn. Everything after that (arrangement, audit, transaction and minimum fees) is where two quotes stop being comparable, and it is the part that rarely makes it into a headline rate.

Service Charge

The service charge is billed as a percentage of the invoices put through the facility, so it scales with turnover rather than with borrowing. Discounting rates sit below factoring rates for the straightforward reason that the provider is not collecting your debts for you.

The catch is the minimum. Most facilities carry a minimum monthly or annual service charge, and if your turnover falls below the level the percentage assumed, you pay the minimum anyway. A quiet quarter costs you what a busy one would. Ask for that minimum in pounds before you compare any percentages, because a 0.65% service charge with a £600 monthly floor is a different product from a 0.65% service charge without one. We treat that floor as part of the headline price rather than a footnote.

Discount Charge and the Reference Rate

The discount charge is interest, and it is normally quoted as a margin over a reference rate rather than as a flat percentage. A lender offering two points over base is not charging you 2%.

A 2 percentage point margin against a 3.75% Bank Rate gives a financing rate of 5.75% a year. It accrues daily on the money you have actually drawn, not on the face value of your invoices, and only for as long as the invoice stays unpaid. That is why your customers’ payment habits move your bill more than the headline rate does.

Other Fees

The rest of the charges are individually small and collectively decisive. Ask for each of these in writing, with the amount, before you sign anything:

• Arrangement or setup fee: often a percentage of the facility limit, sometimes a flat sum, usually payable whether or not you draw.
• Audit or survey fee: charged for the provider’s periodic inspection of your sales ledger, typically annually or more often, and sometimes billed per visit plus expenses.
• Minimum service charge: the floor described above.
• Transaction and same-day payment charges: per drawdown, and higher for CHAPS than for Bacs.
• Non-utilisation fee: charged on the part of the facility you do not use, which turns unused headroom into a running cost.
• Credit protection charge: where bad-debt cover is bolted on.
• Renewal fee: on each anniversary.
• Termination fee and notice period: what it costs to leave, and how long you must give.
• Refactoring or disapproval charge: applied when an invoice ages past the recourse period and the provider re-debits the funding.

Does VAT Apply to Invoice Discounting Fees?

Not uniformly, and “the fees are plus VAT” is the wrong answer. We took the treatment below from HMRC’s own notice rather than from market summaries, because HMRC treats the components of an invoice discounting facility differently. They are different supplies.

Source: HMRC, VAT Notice 701/49 Finance, paragraph 5.5. Checked 24 August 2026.

Two things follow from that. In a non-recourse facility, HMRC notes at paragraph 5.4 that the charge for accepting default risk is usually reflected in an enhanced service charge rather than billed on its own line, so it may never appear separately. And a VAT-registered business making taxable supplies will normally recover the VAT charged, which makes this a question of cash-flow timing rather than cost. If your supplies are exempt or partly exempt, it is a genuine cost, and worth putting to your accountant against the specific facility you are being offered.

The All-In Cost, Worked

A single fee on a single invoice tells you almost nothing. What decides whether a facility is good value is the cash it takes out of the business over a year, so that is what we model. The arithmetic is deliberately reproducible:

1. Average receivables = annual B2B credit sales × average debtor days ÷ 365
2. Average funding drawn = average receivables × advance rate × utilisation
3. Annual finance charge = average funding drawn × (Bank Rate + margin)
4. Annual service charge = eligible turnover × service-charge percentage, or the contractual minimum if that is higher
5. Indicative annual cost = finance charge + service charge + fixed and other fees

Run that on a business with £1m of annual B2B credit sales, customers paying at 60 days, an 85% advance rate, full utilisation, a 0.50% service charge and a 2 percentage point margin over the current 3.75% Bank Rate:

Illustrative. Every input is an assumption, not a quoted rate, and only the 3.75% Bank Rate is a live figure (Bank of England, checked 24 August 2026). Substitute your own turnover, debtor days and quoted rates.

The useful number is the last one. Around 1.3% of turnover is a figure you can hold against a bank overdraft, a revolving facility or the cost of simply waiting to be paid. A quoted margin of “2% over base” is not.

How 30, 60 and 90-Day Payment Terms Change the Cost

Change nothing except how quickly your customers pay, and the annual bill nearly doubles:

Same £1m turnover, 85% advance, 0.50% service charge and 5.75% financing rate throughout. Illustrative.

Look at the two middle columns rather than the total. The finance charge triples between 30 and 90 days because you are borrowing three times as much for three times as long. The service charge does not move at all, because it is levied on turnover and your turnover has not changed.

That has a consequence most quote comparisons miss. At 30 days the service charge is 55% of the bill; at 90 days it is 29%. The faster your customers settle, the less the headline margin matters and the more the service charge and its minimum decide the bill. If you are chasing a lower margin while accepting a higher service charge, check which way round your own ledger sits before you sign.

Who Invoice Discounting Is For

Invoice discounting suits an established business selling to other businesses on credit terms, with a sales ledger a provider can audit and a credit-control function that already works without being asked twice. Everything else follows from those three conditions.

What Providers Require

There is no market-wide minimum turnover, and any single figure quoted as one is somebody’s guess. Three mainstream lenders publish thresholds that span more than three times:

Provider criteria taken from each lender’s own site and checked 24 August 2026. Published criteria are a starting point for a conversation, not an underwriting decision, and none of these lenders publishes its pricing.

Read down the turnover column before you accept any general figure. The spread is not a disagreement about the product; it is each lender deciding what size of client it wants, and it means a business turned down by one may be comfortably inside another’s range. We took each figure from the lender’s own site on the date shown, and we have deliberately not averaged them into a market minimum.

Turnover is only the entry test. Providers also look at how promptly your ledger is paid, how much of it sits past terms, how often you raise credit notes, how many invoices end in dispute, your bad-debt history, and whether your accounting system produces a ledger they can reconcile. Expect a pre-lend survey, an annual audit, a debenture over the business, and in many cases personal guarantees or a warranty from the directors.

Can Start-Ups Use Invoice Discounting?

Usually not, and the reason is worth understanding rather than working around. A discounting provider is lending against a ledger it can audit and a collections process it can rely on, and a business six months old has neither. There is no payment history to test and no evidence that anyone in the business chases an overdue invoice.

Factoring is the normal route in, because the provider takes over the collections and so prices a risk it can then control, and its entry requirements are correspondingly lower. Selective invoice finance, where you fund individual invoices rather than the whole ledger, is the other option for a business that is not ready to commit its entire sales ledger.

When Invoice Discounting Is a Poor Fit

Some businesses are ruled out by how they sell rather than by how well they are doing:

• You sell to consumers, or take card and cash payments at the point of sale. There is no credit invoice to fund.
• You bill by stage payments or applications for payment rather than by invoice, which is common in construction and is why many providers treat the sector separately.
• One customer dominates your ledger, so concentration limits cut the funding well below the headline advance rate.
• Your contracts contain pay-when-paid terms, or your customer can set off amounts you owe them against what they owe you.
• You raise a high volume of credit notes or your invoices are frequently queried. Disputed invoices are ineligible from the moment they are disputed.

There is a harder case to make too. Invoice discounting moves cash forward; it does not make an unprofitable business profitable. A facility taken out to paper over a margin problem adds a cost to that problem, and does it while committing you to a notice period. We rate that as the most expensive way to postpone a decision in this market.

How Invoice Discounting Works

The money moves in five steps: you invoice, the provider works out what it will fund, you draw against it, the customer pays, and the provider squares the account and releases what is left.

Setting Up a Facility vs Drawing on an Invoice

These are two different clocks, and providers advertise the second one. Drawing against an invoice on a live facility is same-day or next-day, and that part of the marketing is accurate.

Setting the facility up is a matter of weeks. There is a survey of the sales ledger, credit checks on the business and often on its customers, a debenture to register, legal documentation to agree, and an integration with your accounting system to configure. HSBC puts the whole process in the region of ten to fifteen working days. If you need cash this month, start now rather than when the shortfall arrives.

A Worked Example

Take a single £20,000 invoice on 60-day terms, with an 85% advance rate, a 0.50% service charge and a 5.75% financing rate:

Illustrative. Total cost on this invoice is £261, or 1.30% of its value, before arrangement, audit and transaction fees.

Note where the discount charge lands. It is calculated on the £17,000 you actually drew, for the 60 days it was outstanding: not on the £20,000 invoice, and not for a year. If that customer pays on day 30 instead, the same invoice costs you £180 rather than £261.

Confidential, Disclosed and the Payment Account

The honest position is that invoice discounting is commonly confidential, not invariably. In a confidential facility your customer is not told a lender is involved, receives your invoice, and pays as they always have. In a disclosed facility a notice of assignment goes to your customer telling them the debt has been assigned and where to pay, while you still run the credit control, which is what separates disclosed discounting from factoring.

Either way, the payments are normally directed into a trust or collection account. That account is usually in your business name, so nothing on the remittance advice looks unusual to the customer, but it is controlled by the provider, which is how the lender sees the money arrive and applies it to your account without relying on you to pass it on.

Two questions are worth asking about confidentiality specifically, because it is the reason most businesses choose discounting in the first place. Ask whether the agreement reserves the provider’s right to notify your customers, and ask what would trigger that. Confidentiality is a term you are granted on conditions, and the conditions are in the contract rather than in the brochure.

How Much Cash You Can Actually Draw

An 85% advance rate is 85% of your eligible debt, and eligible debt is a smaller number than your sales ledger. We rate this as the biggest gap between what invoice finance is advertised to do and what arrives in the account, and it is not usually explained until the first funding statement.

Providers strip out, among others:

• invoices older than the recourse or ageing limit, commonly 90 days from invoice date;
• invoices that are disputed, queried or subject to a credit note;
• the part of any customer’s balance above their debtor concentration limit;
• invoices to customers with no approved credit limit, or who have used theirs up;
• invoices to a customer who is also one of your suppliers, where they could set off what you owe them;
• intercompany and related-party invoices, and often export invoices unless the facility specifically covers them.

Debtor concentration is the one that catches growing businesses. It is the proportion of your ledger owed by a single customer or connected group, and providers cap it: commonly somewhere between a fifth and a third, though it is negotiated facility by facility. Win a contract that doubles your turnover with one client and you can end up with a larger ledger and less funding against it than you had before.

Put the deductions together on a £250,000 ledger and the arithmetic looks like this:

Illustrative. 85% of the full ledger would be £212,500. The advance rate did not change; the number it applies to did.

So the facility advertised at 85% is funding 57% of the ledger. Neither figure is wrong and nobody has misled anyone, but only one of them is the amount you can spend. When you compare quotes, ask each provider to model the advance against your actual aged debtor report rather than against the headline percentage. If I had to pick one number to check before signing, it would be that one.

What Happens if a Customer Pays Late or Never Pays

In most facilities, you do. Invoice discounting is normally provided with recourse, which means the credit risk on your customers stays with you, and the provider can take back funding it has advanced against an invoice that has not been paid.

The mechanism is worth understanding before it applies. Each facility has a recourse period, commonly 90 days from the invoice date and sometimes 120. If the invoice is still unpaid when that period expires, the provider re-debits the advance from your availability. Nobody sends you a bill; the money simply stops being there. A customer who went quiet in month two costs you the £17,000 you drew on day 91, and it comes out of the same availability you were relying on for that month’s wages.

That is the risk the product actually carries, and it is why the quality of your credit control decides whether a discounting facility is cheap or expensive. The saving over factoring is real, but you only keep it if the invoices keep getting paid. We rate the re-debit at the end of the recourse period as the least understood term in the product.

Bad-debt protection, sold as non-recourse or credit protection, changes that picture, within limits that deserve reading properly. Cover is normally written against specified risks such as a customer’s insolvency or protracted default, capped at an approved credit limit for each customer, and paid at a percentage of the invoice rather than all of it. It generally does not cover disputes at all, and a disputed invoice is precisely the one you are most likely to lose. Before you pay for it, ask what proportion of your current ledger would actually sit inside approved limits.

A dispute is the other thing to plan for. An invoice becomes ineligible the moment your customer queries it, whoever turns out to be right, so a single argued-over invoice withdraws funding at the same time as it withdraws the payment. Businesses with a high query rate should treat that as a cost of the facility rather than an occasional annoyance.

How Invoice Discounting Affects Your Accounts

Invoice discounting is generally a form of short-term borrowing supported by your receivables, and in a typical recourse facility it appears in your accounts as such. The widespread claim that invoice finance does not add debt is not safe to rely on.

Under FRS 102, a financial asset such as a trade receivable is derecognised only where the contractual rights to the cash flows expire or are settled, where substantially all the risks and rewards of ownership have been transferred, or where control has passed to someone with the practical ability to sell the asset outright. A recourse facility fails that test by design: recourse means you keep the credit risk. The invoices therefore stay on your balance sheet, and the money advanced against them sits alongside as a liability.

Source: FRS 102 Section 11, as summarised in HMRC’s Corporate Finance Manual at CFM23075. Checked 24 August 2026.

Where risk genuinely does transfer (some non-recourse structures), derecognition can be the right treatment. That treatment is a judgement about your specific agreement rather than a property of the product, and it turns on how much risk your contract actually moves. Your accountant makes that call, and it is worth asking the question before the year-end rather than during it.

It matters beyond presentation. A liability on the balance sheet affects your gearing, can eat into covenant headroom on other facilities, and will be read by any lender or investor looking at your accounts. If you are planning to raise money in the next eighteen months, find out now how the facility will be presented.

Invoice Discounting vs Invoice Factoring

One difference drives all the others: with discounting you keep the credit control, and with factoring you hand it over. Everything in the table below follows from that single choice.

We keep this short on purpose. If you are choosing between the two rather than deciding whether discounting suits you at all, our dedicated comparison walks through the decision in full, including the cost difference on a worked ledger.

Is Invoice Discounting Regulated in the UK?

Neither “it is FCA regulated” nor “it is unregulated” is accurate, and the difference matters when something goes wrong. We separate three questions here, because collapsing them is how both of those wrong answers get published.

1. Is your agreement a regulated credit agreement? For a limited company, no. The consumer credit regime covers individuals and what the legislation calls relevant recipients of credit: sole traders, partnerships of up to three, and unincorporated bodies. Even for those, article 60C(3) of the Regulated Activities Order exempts an agreement where the lender provides credit exceeding £25,000 and the borrower enters into it wholly or predominantly for business purposes. So a sole trader with a facility of £25,000 or less for business purposes can fall inside the regime; a limited company does not.

2. Is the provider an authorised firm? Often, yes: several of the largest invoice discounters are banks, and others hold permissions for parts of their business. That is not the same thing as your agreement being regulated, and it is where the two claims above get conflated. Check the Financial Services Register for what the firm’s permissions actually cover before you draw any comfort from the word authorised in a brochure.

3. If you have a complaint, who hears it? This is the question worth asking, and almost nobody does. UK Finance runs a Standards Framework for invoice finance and asset-based lending, made up of an industry Code and an independent complaints process operated by CEDR. It applies only to members.

• There is no charge to the complainant, whether or not the complaint is upheld; the member meets CEDR’s costs.
• The complaint must concern an invoice finance or asset-based lending facility and seek £50,000 or less.
• It must be raised with the member within 12 months of the issue, and registered with UK Finance within 6 months of the member’s final response.

Sources: Financial Services and Markets Act 2000 (Regulated Activities) Order 2001, article 60C(3); UK Finance, Invoice Finance and Asset-Based Lending Standards Framework and its complaints process. Checked 24 August 2026.

Ask any provider you shortlist whether it subscribes to that framework. Where the agreement is not a regulated credit agreement, the Financial Ombudsman Service will not normally be able to consider a complaint about it, which leaves an independent complaints process as the main protection on offer. It costs nothing to ask before you sign, and a great deal to find out afterwards.

Can a Contract Stop You Assigning an Invoice?

Customers sometimes write a ban on assignment into their purchase terms, which would in principle stop you financing their invoices at all. For most UK business contracts entered into on or after 31 December 2018, that clause no longer works.

The Business Contract Terms (Assignment of Receivables) Regulations 2018 provide that a term in a business contract has no effect to the extent that it prohibits or imposes a condition or other restriction on the assignment of a receivable. Terms designed to make an assignment impractical (by withholding the contract details, invoice numbers or VAT information an assignee needs to enforce or value the debt) are caught as well.

There are exceptions, and we checked the regulation itself rather than the commentary on it, because they matter. The protection does not apply where the supplier is a large enterprise or a special purpose vehicle, and certain contract types are excluded, including financial services contracts. If a major customer’s terms contain a non-assignment clause and you are relying on that ledger for funding, put the clause in front of your solicitor and the provider together before the facility is agreed.

How to Compare Invoice Discounting Quotes

Providers compete on the discount margin because it is the number a business recognises. It is rarely the number that decides which facility is cheaper.

The All-In Quote Decoder

We built two illustrative offers on the model above and put them to the same business: £1m of B2B credit sales, 60 debtor days, an 85% advance and a £200,000 facility limit. One quotes a keener margin, the other a keener service charge:

Illustrative quotes built on the cost model above. Bank Rate 3.75%, checked 24 August 2026.

Quote B costs £1,352 a year less, even though its margin is three quarters of a percentage point higher. Two things did that. Quote A’s £600 monthly minimum overrides its own 0.65% service charge, so the business pays £7,200 rather than the £6,500 the percentage implies. And the service charge is simply the larger of the two numbers at 60 debtor days, which makes the margin the less important half of the quote.

Run the same five lines on your own figures. On these assumptions the higher headline margin is the cheaper facility, and no comparison table that ranks providers by rate will tell you that.

On these numbers I would take Quote B, and I would want that minimum service charge confirmed in writing before signing anything.

Questions to Ask Before You Sign

Ask for the answers in writing, and ask every provider the same list so the replies can be laid side by side:

• What is the reference rate, what is the margin over it, and on what balance does it accrue?
• What is the service charge, and what is the minimum in pounds per month or year?
• What are the arrangement, audit, renewal and transaction fees, and is there a non-utilisation charge?
• Model the advance against my aged debtor report: what is the eligible debt, and what is the cash?
• What is the concentration limit per customer, and how is a connected group treated?
• What is the recourse period, and what happens on the day it expires?
• If bad-debt protection is included, what does it exclude, and what percentage of my current ledger sits within approved limits?
• Is the facility confidential, and in what circumstances may you notify my customers?
• What is the minimum term, the notice period and the termination fee?
• What security is taken, and are personal guarantees required from directors?
• Do you subscribe to the UK Finance IF/ABL Standards Framework?

A provider who answers all eleven quickly is telling you something about how the facility will be run. So is one who does not.

Approaching lenders one at a time is the thorough way to collect those answers, and it is slow. A marketplace shortens it: Tide Funding Options puts a single application to a panel of invoice finance lenders, which is a practical way to get discounting and factoring quotes side by side.
