What Invoice Discounting Actually Is
Invoice discounting lets your company borrow against the value of its unpaid business-to-business invoices while you carry on running your own sales ledger. Instead of waiting 30, 60 or 90 days for customers to pay, your business draws down a percentage of the debtor book as cash, then repays the funder as your customers settle. The defining feature is that you keep control: you raise the invoices, you chase payment, and you manage collections exactly as you did before the facility existed.
In its most common form, confidential invoice discounting (CID), the arrangement is invisible to your customers. They pay as normal, into an account that carries your own branding, and they never learn that a funder sits behind your cash flow. That confidentiality, combined with keeping collections in-house, is what separates discounting from its more hands-on sibling, factoring. For the full menu of options and where discounting sits among them, see our complete guide to invoice finance.
Discounting funds the debtor book rather than the balance sheet as a whole, so the facility flexes with your sales. As turnover grows, the amount you can draw grows with it, without renegotiating a fixed loan each time. That makes it a natural fit for companies with steady, growing B2B sales and the systems to run their own credit control to a lender's satisfaction.
Confidential by Design: Your Customers Stay Unaware
The word that matters most in confidential invoice discounting is confidential. Unlike factoring, where customers are formally notified that a funder now collects their account, CID keeps the whole arrangement private between your company and the lender.
In practice, your invoices continue to go out under your own name with your own payment details. Customers remit to a trust or collection account that appears to be yours, and your finance team chases overdue invoices in the usual way. Nothing on the invoice, the statement or the phone call reveals a funder is involved. For companies that guard their customer relationships closely, or that worry an external collections team would signal cash-flow strain, that invisibility is the entire point.
The contrast with factoring is stark on this single axis. Factoring is disclosed and the funder does the chasing, which suits a company without a credit controller. Discounting is confidential and you do the chasing, which suits a company that has one. If keeping customers unaware matters to you, discounting is usually the only version of invoice finance that delivers it, and our guide to invoice factoring sets out the disclosed alternative in full.
You Run Your Own Credit Control
Because the facility is confidential, collections stay with your company. That is a responsibility as much as a benefit, and it shapes who invoice discounting is right for.
On the upside, you keep ownership of every customer conversation. Nobody chases your key accounts more aggressively than you would, and a valued relationship is never handled by a third party who does not know its history. You also avoid the factoring service fee that pays for outsourced collections, which is why discounting is materially cheaper for a company that can collect well itself.
On the responsibility side, the lender is trusting your ledger discipline. If your credit control slips, overdue invoices build and the funder can pull back the advance rate or exclude aged debt from the facility, tightening your cash just when you need it. Discounting therefore rewards companies with a competent finance function, current management accounts and reliable reconciliation, and punishes those that let the ledger drift.
Eligibility: Covenant, Turnover and Systems
Invoice discounting carries a higher eligibility bar than factoring, precisely because the funder does not collect and so relies on your covenant and controls. Three tests dominate.
- Turnover and scale. Most funders set a minimum turnover for a confidential whole-turnover facility, commonly £250,000 to £500,000 a year, with many reserving CID for companies above roughly £500,000. Below that, factoring is usually offered instead.
- Covenant and trading strength. The lender assesses your company's financial health, profitability and balance sheet, not just your customers' credit. A stronger covenant secures a higher advance rate and a confidential rather than disclosed facility.
- Systems and controls. Because you collect, funders scrutinise your accounting software, credit-control process, reconciliation discipline, historic bad-debt levels and the age and spread of your debtor book. Many require regular electronic ledger uploads and periodic audits.
A concentrated debtor book, where one or two customers make up most of your sales, is the most common reason for a lower advance or a decline, because it concentrates the funder's risk. A well-spread ledger of creditworthy B2B customers, paired with clean management information, is what unlocks the best terms.
What It Costs: Advance Rate and Discount Margin
Two numbers set the cost of a discounting facility, and a third is where discounting quietly beats factoring.
- The advance rate. Typically 80% to 90% of the approved debtor book, often at the top of that range for a strong, well-spread ledger. You draw against the whole eligible book, not invoice by invoice.
- The discount margin. Charged like interest, usually around 2% to 4% over base rate, on the funds you actually draw, for as long as they are drawn. This is broadly the same on discounting and factoring.
- The service or admin fee. Here is the difference. Because you run collections, the discounting admin fee is far lower than the factoring service fee, commonly 0.2% to 0.5% of turnover against 1% to 3% for factoring.
Watch also for arrangement fees, minimum monthly fees, audit or survey fees, and same-day payment charges, as with any invoice-finance facility. But the service-fee gap is the headline: it is the price of the collections service you are choosing to keep in-house.
Worked example: a £500,000 ledger on CID versus factoring
Take a company turning over £6,000,000 a year on 30-day B2B terms, with around £500,000 outstanding on its sales ledger at any one time. It arranges confidential invoice discounting at a 90% advance rate, so up to £450,000 of cash is available to draw against that ledger, self-managed.
Now compare the annual running cost against factoring the same book:
| Cost element | Invoice discounting (CID) | Factoring |
|---|---|---|
| Advance rate | 90% (up to £450,000) | 85% to 90% |
| Service or admin fee on £6m turnover | 0.3% = about £18,000/yr | 1.5% = about £90,000/yr |
| Discount margin on drawn funds | Similar (say 8% all-in) | Similar (say 8% all-in) |
| Who runs credit control | Your company | The funder |
| Customers notified? | No, confidential | Yes, disclosed |
The discount margin is broadly the same on both, so it nets out of the comparison. The gap is the service fee: roughly £18,000 a year on discounting against £90,000 on factoring, a difference of about £72,000. That £72,000 is the price of the factor's collections team. If your finance function can chase your own ledger competently, discounting keeps that money in the company. If it cannot, factoring buys you a service worth paying for. That is the whole decision in one line.
CID vs Factoring vs Selective Discounting
Discounting is not one product. The right version depends on how much of your ledger you want to fund and how much control you want to keep.
| Feature | Confidential discounting (CID) | Factoring | Selective / spot discounting |
|---|---|---|---|
| Customers notified? | No | Yes | Usually no |
| Who collects? | Your company | The funder | Your company |
| Scope | Whole ledger | Whole ledger | Chosen invoices only |
| Typical cost | Lower | Higher | Higher per invoice, no lock-in |
| Best for | Established companies, strong systems | Smaller or under-resourced finance teams | Occasional or lumpy cash gaps |
Whole-turnover CID funds your entire eligible ledger and is the cheapest per pound because the lender gets the whole book. Factoring adds the collections service and the disclosure that comes with it. Selective or spot discounting lets you finance individual invoices or a single customer with no whole-turnover commitment and no long minimum term, at a higher per-invoice cost, which suits a company with occasional gaps rather than a constant need. If your funding requirement is really about seasonal or one-off pressure rather than a permanent facility, compare it against a working capital finance facility or a revolving credit line before committing your whole ledger.

Invoice Discounting vs Supply-Chain Finance
Companies often confuse invoice discounting with supply-chain finance, but they run in opposite directions and it pays to know which side of the deal you are on.
Invoice discounting is seller-led. Your company finances its own sales ledger, drawing cash against invoices you have issued, priced on your covenant and your customers' credit. You control it and you carry the collections.
Supply-chain finance, also called reverse factoring, is buyer-led. A large buyer sets up a programme, usually with a bank, that lets its suppliers take early payment on approved invoices against the buyer's stronger credit rating. The buyer then settles with the bank later on its normal terms. If a big customer offers to pay you early through their finance platform, that is supply-chain finance, priced on their covenant, not yours.
The practical point: if you are financing your own book yourself, you want invoice discounting. If your funding is coming through a customer's early-payment programme, that is their supply-chain finance scheme and a different arrangement entirely. Many companies use both, discounting the rest of the ledger while taking early settlement where a large buyer offers it.
Company Borrowers Only: How We Fit In
Company borrowers only. The finance introductions on this page are for UK limited companies and limited liability partnerships borrowing for business purposes. We introduce your company to a panel of commercial-finance brokers; we are not a lender and do not give regulated credit advice. If you are a sole trader, an individual, or borrowing for personal or household purposes, this service is not for you and you should speak to an FCA-authorised consumer-credit firm.
Introducing a body corporate to a finance provider is not credit broking under Article 36A of the Financial Services and Markets Act 2000 (Regulated Activities) Order 2001, which is why this cluster is fenced to companies. Separately from the finance itself, our own accountants at Holloway Davies can advise on how discounting costs are treated for tax. For a limited company, admin fees and discount charges are normally allowable revenue deductions against trading profit, reducing your corporation-tax bill at your marginal rate (19% up to £50,000 of profit, 25% above £250,000, with an effective 26.5% marginal band between). VAT treatment varies by charge type, and the VAT registration threshold sits at £90,000, covered in our note on the VAT registration threshold. Speak to us for the tax and structuring angle once the facility is in place.
How to Apply
A discounting funder assesses three things before offering a confidential facility: the strength of your company's covenant, the credit quality and spread of your debtor book, and the robustness of your systems and credit control. Because you keep collecting, that last point carries more weight than it does with factoring. Clean, current management accounts, a well-spread customer base and a tidy sales ledger with clear proof of delivery all speed approval and lift the advance rate you are offered.
Setting up a confidential facility usually takes two to four weeks, longer than factoring because the diligence on your controls is deeper, and once live you draw against the approved ledger on demand, typically through an online portal with regular reconciliation uploads. Terms vary widely between funders on advance rate, margin, admin fee and minimum term, so comparing several is worth the effort, and a broker panel does that matching in one step.
