Invoice discounting is a form of invoice finance where a funder lends against your unpaid business invoices, typically around 80% to 90% of eligible debts, while your own team keeps running credit control. It is usually confidential, so customers do not know a funder is involved. Lenders generally expect an established turnover, a trading track record and reliable ledger controls, checked through regular audits.
This page is for established B2B businesses with a finance function of their own that want to turn their debtor book into working capital without handing over customer relationships. Invoice discounting lets you borrow against your unpaid invoices while your own team keeps chasing payment, and in most cases your customers never know a funder is involved. Smart Funding Solutions is a broker, not a lender. We search lenders on our panel of 300+ for invoice discounting facilities from around £10,000 to £500,000+, with larger facilities available in suitable cases. For a wider view of receivables funding, see our invoice finance hub.

Invoice discounting is a revolving facility secured on your sales ledger: the funder advances a percentage of your approved debts, you keep collecting from customers, and the money they pay reduces what you owe. It behaves less like selling invoices one by one and more like a credit line that rises and falls with your debtor book.
Because you only pay interest on what you draw, an invoice discounting facility can sit partly unused and act as headroom for growth, large orders or seasonal peaks.
Most invoice discounting is confidential, meaning your customers are not told about the facility, but some lenders offer a disclosed version where a notice of assignment appears on invoices while you still run collections. Confidentiality is a privilege lenders grant to businesses they trust, and they can withdraw it if reporting deteriorates or the business runs into difficulty.
A confidential facility suits firms that worry customers or competitors might read invoice finance as a sign of weakness, or whose contracts make disclosure awkward. If confidentiality is your main requirement, our page on confidential invoice finance explains the options in detail, including for businesses that do not yet meet every discounting criterion. A disclosed discounting facility can be easier to obtain and is sometimes a stepping stone between factoring and full confidentiality.
Whole-turnover invoice discounting funds your entire trade ledger under one facility, while selective discounting funds only the invoices or customers you choose. The choice shapes the cost, the commitment and how much funding you can reach.
Whole-turnover facilities give the highest availability and usually the lowest cost per pound borrowed, because the funder sees and secures the whole book. In return they carry a minimum term and a notice period, and minimum fees apply even in quiet months. Selective discounting avoids that commitment and suits businesses that only need occasional cash against a few large invoices. Per invoice it is generally more expensive, and some providers take only debts owed by strong customers. Our page on selective invoice finance covers that route.
Invoice discounting suits businesses with a meaningful turnover, a trading track record and reliable credit control and ledger systems of their own. Lenders are handing day-to-day management of their security back to you, so they want evidence that your team collects well and reports accurately.

Young and smaller businesses commonly start with factoring and move across once they meet these thresholds.
Every invoice discounting facility comes with ongoing reporting and periodic audits, because the funder relies on your records rather than running the ledger itself. Expect to upload sales and cash information regularly and to provide a full aged debtor report and reconciliation, usually monthly.
Before the facility starts, the lender typically carries out a survey of your systems and a sample of debts. After that, audits recur at intervals set by the lender, often once or twice a year, and more often if issues appear. Auditors test that invoices reflect real deliveries, that credit notes are recorded promptly, that cash is banked correctly and that no customer has been contacted to pay elsewhere. Findings can lead to tighter eligibility rules or, in serious cases, to the loss of confidentiality.
A new invoice discounting facility typically takes two to four weeks to put in place, and larger or more complex cases can take longer. The survey of your systems, legal documentation, any release of security by an existing lender and the funder's verification of a sample of debts all affect the timetable. Well-organised management information shortens it considerably. Once live, drawings against reported debts are often available within a working day, depending on the funder's cut-off times.
Invoice discounting is secured on your book debts through an assignment, almost always supported by a debenture giving the funder a fixed charge over debts and a floating charge over other assets. Our guide to debentures and fixed and floating charges explains what each covers.
Because you control collections, lenders often ask directors for warranties that the information supplied is accurate, and an indemnity covering losses caused by invalid invoices. Many also request a personal guarantee, sometimes limited to a fixed amount. Our guide to personal guarantees sets out what to check before you sign. If you already have bank borrowing, the bank and the discounter will normally need an agreement on which of them has priority over which assets.
Invoice discounting is priced mainly through a service fee and a discount charge, and the service fee is usually lower than on factoring because the funder is not running your credit control. You are paying for funding and administration, not collections.
Whole-turnover agreements commonly carry a minimum term, often 12 months, and a notice period, often three months. Compare total cost on your realistic turnover and drawing pattern, not only the headline fee.
The main alternatives are invoice factoring, selective funding, a revolving credit facility or a broader asset-based facility, depending on your size and what you need the money for.
Discounting lenders assess the quality of your debtor book and, more heavily than in factoring, the strength of your own systems and financial position. They want confidence that the figures you report are true and that collections will continue without their involvement.
Lenders band facilities by turnover, and many want at least one or two years of filed accounts.
Average debtor days against your terms, how quickly overdue accounts are resolved and your record of bad debts.
How promptly invoices, credit notes and cash are posted, whether you reconcile monthly and how well your accounting system reports.
The credit standing of your customers and the share of the book held by any one of them, which drives the concentration limit.
How much invoiced value is lost to credit notes, rebates and contested invoices.
Profitability, net worth, existing borrowing and charges, and your VAT and PAYE position.
Lenders usually ask for your last two years of filed accounts, recent management accounts and a detailed aged debtor and creditor report. A typical application also includes:

£250,000
Payroll every week. Customers paying in 45 to 60 days.
A growing recruitment agency needed funding that moved with its debtor book, not another fixed loan. We arranged confidential invoice finance.
Profitable growth can still create a cash-flow problem when wages are paid long before customers settle invoices.

How the main business finance structures work. Lenders set their own terms, so treat this as a guide to the questions to ask.
| Option | How you repay | Security | Often used for |
|---|---|---|---|
| Unsecured business loan | Fixed instalments, usually monthly | No charge over assets; a personal guarantee is usually required | Growth, stock, tax bills and cash flow |
| Secured business loan | Fixed instalments, often over a longer term | A charge over property or other assets | Larger sums, property and refinancing |
| Revolving credit facility | Interest on what you draw; repay and redraw | Varies by lender and case | Recurring or uneven cash flow gaps |
| Merchant cash advance | A share of future card takings | No charge over assets | Card-taking businesses with uneven months |
| Asset finance | Regular payments over the life of the asset | The asset being financed | Equipment, vehicles and machinery |
| Invoice finance | Settled as customers pay their invoices | Your unpaid invoices | Businesses waiting on customer payment |
General information only. Every lender has its own criteria, and all finance is subject to status.
The essential difference is control: with invoice discounting you run your own sales ledger and customers usually do not know about the funder, while with factoring the funder takes over collections and is disclosed.
| Feature | Invoice discounting | Invoice factoring |
|---|---|---|
| Credit control | Your business | The funder |
| Disclosure to customers | Usually confidential | Usually disclosed |
| Service fee | Lower | Higher, as collections are included |
| Eligibility | Established turnover, track record and ledger controls | Accessible to younger and smaller businesses |
| Monitoring | Reporting and periodic audits | Funder sees every payment as it runs the ledger |

We review your turnover, ledger and systems against what discounting lenders expect, and tell you plainly if factoring or a disclosed facility is the more realistic starting point. We then approach lenders on our panel whose appetite suits your sector and size, and compare service fees, discount charges, minimums, audit arrangements, notice periods and security so you can judge the full cost. Lenders make every credit decision, and we help you through the survey and any handover from an existing funder. It is free to enquire; any broker fee is disclosed separately before you proceed. To discuss your debtor book, contact our team.
Illustrative figures from the numbers you enter, before you speak to a lender.
If trading deteriorates, reporting falls behind or audits reveal problems, the funder can convert the facility to a disclosed basis and, in serious cases, take over collections. The agreement sets out the triggers. Keeping the funder informed early, and reporting accurately, usually gives you more room to agree a plan than waiting until covenants are breached.
Yes, subject to your notice period and any early termination terms. The new funder normally pays off the existing lender's outstanding balance on the switch date, takes an assignment of the ledger and registers fresh security, while the old charge is released. Timing the move around your notice date avoids paying two sets of minimum fees.
In most cases the debts stay on your balance sheet and the funding appears as a liability, because you retain the credit risk and control of collections. Accounting treatment depends on the agreement and the standards you report under, so ask your accountant how a specific facility should be presented before you finalise it.
It can, but both lenders will want security, and a bank may already hold a debenture covering your book debts. Normally the bank agrees to release or subordinate its claim over debts so the discounter takes first ranking there, while the bank keeps priority elsewhere. Many businesses replace the overdraft entirely, as a discounting line usually grows faster with sales.
There is no single turnover figure, as each lender sets its own minimum, but invoice discounting is generally offered to established businesses with larger turnovers and reliable credit control. Lenders also look at trading history, the quality of your customers and your accounting systems. Smaller or younger businesses often start with invoice factoring and move to discounting as they grow.
