If you run a B2B business and you’ve ever found yourself watching a healthy bank balance become a cash crisis simply because customers are slow to pay, invoice finance is probably worth understanding properly. It’s one of the most effective and most underused cashflow tools available to UK small businesses — and in 2026, with late payments costing the UK economy almost £11 billion a year and closing around 38 businesses every single day according to government figures, it’s a tool that’s genuinely relevant to a very wide range of SMEs. Yet a surprising number of business owners either don’t know it exists, assume it’s only for larger firms, or dismiss it based on a partial understanding of what it actually costs. This guide is an honest, plain-English walkthrough of what invoice finance is, how the different types work, what it realistically costs in 2026, and when it does — and doesn’t — make sense.
Whether you’re drowning in unpaid invoices or just planning ahead for a growth phase, the principles here will give you a clear picture of what’s actually on offer.
Quick Answer: What Is Invoice Finance?
Invoice finance is a form of short-term business funding that allows UK businesses to release cash tied up in unpaid invoices rather than waiting 30, 60, or 90 days for customers to pay. Typically, a lender advances 70-90% of the invoice value within 24-48 hours of it being raised; the remainder (minus fees) is paid when the customer settles. There are two main types: invoice factoring (where the lender manages credit control and your customers know about the arrangement) and invoice discounting (confidential — your customers continue paying you directly). Costs typically comprise a service fee of 0.5-3% of annual turnover and a discount charge (interest) of roughly Bank of England base rate plus 2-4%. In 2026, with the base rate at 3.75%, effective annual rates on drawn balances run approximately 5.5-8.25%. Invoice finance is available from major banks and specialist lenders, with selective or spot options available for businesses that want flexibility without a full facility.
How Invoice Finance Actually Works
Invoice finance is, at its core, a way of converting your sales ledger — the money you’re owed — into immediate working capital. Rather than a traditional loan where you borrow a fixed sum and repay it on a schedule, invoice finance advances money against invoices as you raise them, and the repayment is funded by your customers’ payments when they arrive.

Here’s how a typical transaction works in practice. A business raises a £10,000 invoice with 60-day payment terms. Under a standard invoice finance arrangement with an 85% advance rate, the lender releases £8,500 to the business within 24-48 hours. When the customer pays the £10,000 invoice 55 days later, the lender deducts its service fee and the discount charge (interest for the 55 days the advance was outstanding), and releases the remaining balance. The business has had access to £8,500 for almost two months, paying only for the period the money was actually drawn — not a flat fee for a fixed loan term.
This is one of the important structural differences from a business loan: invoice finance scales automatically with your revenue. If your sales double, the funding available roughly doubles too — without a new application, a new credit check, or a renegotiation. For growing businesses where cashflow is being squeezed by rapid expansion, this elasticity is often exactly what’s needed.
Invoice Factoring vs Invoice Discounting: The Key Difference
The most important choice in invoice finance is between its two main forms. The core distinction is who manages credit control — and whether your customers know about the arrangement
Invoice Factoring
With invoice factoring, you hand over your sales ledger to the finance provider. They manage credit control on your behalf: chasing customers for payment, sending statements, and collecting funds. Your customers will know about the arrangement — payment requests arrive from the factor, not from your business directly.
This has real advantages and real drawbacks. On the plus side, you remove the time and cost of internal credit control
— particularly valuable for smaller businesses without a dedicated finance team. The factor also often carries out credit checks on prospective customers before you trade, which adds a layer of debtor risk management. On the minus side, some business owners worry about how their customers will react to dealing with a third party, though in most sectors it’s a well-understood and accepted commercial arrangement.
Factoring is generally accessible at lower turnover thresholds
— some providers will work with businesses from £50,000-£100,000 in annual invoiced sales — making it the more common entry point for smaller or newer businesses.
Invoice Discounting
Invoice discounting is the confidential version. Your customers remain completely unaware of the finance arrangement
— they continue to pay into a bank account in your business name as normal. You retain full control of your credit control function, manage your customer relationships directly, and simply draw down advances against your ledger from a separate funding account with the provider.
Because the lender relies on you to collect the debts rather than managing the process themselves, discounting is generally only available to more established businesses with proven, efficient credit control
and typically carries a minimum turnover requirement of £500,000 or more. The cost is usually lower than factoring because the provider’s administrative burden is smaller.
Which Type Is Right for Your Business?
| Factor | Invoice Factoring | Invoice Discounting |
| Customer awareness | Disclosed — customers know about the arrangement | Confidential — customers unaware |
| Credit control | Managed by the factor | Retained by you |
| Typical minimum turnover | £50,000-£100,000 p.a. | £500,000+ p.a. |
| Cost (service fee) | 0.5-3% of turnover (higher, includes credit control) | 0.2-0.75% of turnover (lower, you handle credit control) |
| Best suited to | Smaller or growing businesses without dedicated finance team | Established businesses with strong internal credit control |
Selective and Spot Invoice Finance: The Flexible Middle Ground
A development that’s made invoice finance accessible to a much wider range of UK SMEs is the growth of selective invoice finance and spot factoring — products that don’t require you to fund your entire sales ledger on an ongoing basis, but instead let you choose which invoices or customers to finance, when you need the cash.
Under a spot factoring arrangement, you can submit a single invoice to be funded — no ongoing contract, no monthly fees, no commitment to fund future invoices. You pick up funding when the cashflow need arises and stop when it doesn’t. Providers including Kriya (formerly MarketInvoice), Bibby Spot, and others offer this model, typically charging a flat fee of 1-3% of the invoice value per transaction rather than the two-component (service fee + discount charge) structure of a full facility.
For businesses that have occasional cashflow gaps rather than a chronic working capital need, selective or spot products often offer a better fit than committing to a full ongoing facility with minimum usage requirements and termination fees. The per-invoice cost looks higher in percentage terms, but if you’re only using the facility two or three times a year, the total absolute cost can be considerably lower than maintaining a full facility year-round.

What Invoice Finance Actually Costs in 2026
Understanding the cost structure is essential before choosing a provider, because headline marketing figures rarely reflect what you’ll actually pay. Invoice finance costs have two separate components, and the total depends heavily on how quickly your customers actually pay
Component 1: The Service Fee
The service fee (sometimes called the administration or factoring fee) covers the provider’s administrative costs — ledger management, credit control if you’re using factoring, and account servicing. It’s calculated as a percentage of your annual invoiced turnover, not of the amount advanced. Typical ranges:
Invoice factoring: 0.5-3% of annual turnover (higher because the provider manages credit control).
Invoice discounting: 0.2-0.75% of annual turnover (lower because you handle credit control yourself).
For a business with £500,000 in annual invoiced sales, a 1.5% factoring service fee means £7,500 a year — before the discount charge is added. This can sound alarming in isolation, but comparing it to the cost of a full-time credit controller (salary, NI, pension) can make the numbers look more proportionate.
Component 2: The Discount Charge
The discount charge is interest — the cost of the money the provider advances to you. It’s charged daily on the actual balance outstanding, and calculated as a percentage above the Bank of England base rate (currently 3.75%) or SONIA. Typical margins:
Well-established businesses, lower risk: Base rate + 2-3.5%, giving effective rates of approximately 5.75-7.25% in current conditions.
Smaller or higher-risk businesses: Base rate + 4-6%, giving effective rates of approximately 7.75-9.75%.
Because the discount charge is only applied for the days the advance is outstanding, the total amount you pay depends significantly on your customers’ payment behaviour. A customer who pays in 30 days costs you roughly half what one who takes 60 days does on the same invoice, everything else equal.
Hidden Costs to Check Before Signing
Beyond the service fee and discount charge, some providers include additional fees that can materially affect the total cost:
Arrangement fee: A one-off setup charge, typically 1-2% of the facility value (or a flat £500-£2,000), covering due diligence, audits, and documentation. Some providers waive this for larger clients.
Bad debt protection: An optional add-on (making the facility “non-recourse” — the provider bears the risk if a customer becomes insolvent) typically adds 0.45-1% to the service charge. Worth considering in sectors with less stable customers.
Minimum usage fees: Some contracts require you to fund a minimum value of invoices per month or year. If your volume falls below this, you pay a minimum charge regardless.
Concentration limits: If one customer represents more than 25-30% of your ledger, some providers charge additional fees or reduce the advance rate on that concentration.
Termination fees: Most full facilities have a minimum term of 12-24 months. Exiting early typically triggers a penalty — check this carefully before signing, and make sure you can genuinely commit for the minimum period.

When Invoice Finance Makes Sense — and When It Doesn’t
When It Works Well
Your business invoices other businesses (B2B) on credit terms. Invoice finance is specifically designed for B2B sales with payment terms of 14-120 days. It doesn’t work for consumer-facing businesses, cash-on-delivery models, or businesses where invoices are typically disputed before payment.
You’re growing faster than working capital allows. Rapid growth often creates a cashflow paradox: the more business you win, the more cash you need to fund labour, stock, or suppliers before the customer pays. Invoice finance solves this by unlocking the cash from growing sales rather than requiring you to wait.
Late payment is a structural problem, not a one-off. For businesses in sectors where 60-90 day payment terms are the norm — recruitment, manufacturing, wholesale, professional services — invoice finance is a systematic solution to a systematic problem rather than a sticking plaster.
You need funding that scales with revenue. A business loan provides a fixed pot; invoice finance scales with your invoiced sales. For businesses growing quickly, this matching of funding capacity to revenue growth is often exactly what the finance structure needs.
When It’s Less Suitable
You’re consumer-facing or don’t invoice on credit terms. Invoice finance requires B2B invoices with payment terms. Retail, hospitality, and most direct-to-consumer businesses aren’t eligible.
Your invoices are frequently disputed. Finance providers advance against invoices for goods and services already delivered and accepted. Industries with routine disputes — certain construction contracts with retention deductions, for example — can face restrictions or reduced advance rates. Disputed invoices are generally excluded from funding.
You only need cashflow occasionally. For infrequent, one-off cashflow gaps, a full facility with a 12-24 month minimum commitment and ongoing fees may cost more than the problem it solves. Spot or selective products are a better fit for occasional needs.
The underlying business is unprofitable. Invoice finance advances your cashflow — it doesn’t change the fundamentals. As the British Business Bank notes, no form of commercial finance makes a fundamentally unprofitable business viable. If the cashflow problem stems from losses rather than timing, the fix is operational, not financial.
How to Apply and What to Expect
The process for setting up invoice finance is typically faster than a traditional business loan
— most facilities can be decisioned within 24-72 hours of a full application, and the first advance often follows within a few days. Here’s what a typical process looks like.
Initial assessment. Most providers will ask for basic information: your annual invoiced turnover, the number and size of your customers, your typical payment terms, and whether you’ve had any significant bad debts. This usually takes place via an online form or a short call.
Due diligence. Once an initial offer is made, the provider will carry out due diligence on your sales ledger — reviewing aged debt, checking customer creditworthiness, and sometimes conducting an audit of your invoicing processes. This is where arrangement fees, if applicable, are typically incurred.
Facility agreement. You’ll receive a detailed facility letter setting out the advance rate, service fee, discount charge, minimum term, any concentration limits, and any additional fees. Read this carefully and compare it against quotes from at least two other providers before signing. The variation in pricing between providers can be substantial.
Going live. Once the agreement is signed, you upload invoices to the provider’s platform as you raise them, draw down advances as needed, and the provider reconciles everything as customers pay. Most modern platforms are straightforward and integrate with common accounting software.
One strong recommendation: use an independent invoice finance broker
rather than going directly to a single provider. The market includes dozens of specialist lenders with different criteria, pricing models, and sector preferences. A broker who searches the whole market can often find materially better terms than approaching Bibby, Novuna, or Close Brothers directly — and most brokers are paid by commission from the lender rather than by you.

Frequently Asked Questions
What is invoice finance and how does it work?
Invoice finance allows UK B2B businesses to release cash from unpaid invoices rather than waiting for customers to pay. A lender advances typically 70-90% of the invoice value within 24-48 hours; the remainder (minus fees) is paid when the customer settles. There are two main types: factoring (disclosed, with the lender managing credit control) and invoice discounting (confidential, with you retaining credit control).
How much does invoice finance cost in the UK?
Costs comprise two elements: a service fee (0.5-3% of annual turnover) and a discount charge (Bank of England base rate plus 2-4%, so approximately 5.75-7.75% in 2026 conditions). The total amount paid depends heavily on how quickly customers pay — since the discount charge only accrues for the days the advance is outstanding.
Is invoice finance the same as a business loan?
No. A business loan provides a fixed lump sum and adds debt to your balance sheet. Invoice finance advances money against invoices you’ve already raised — it scales automatically with your revenue
, involves no fixed repayment schedule, and the ‘repayment’ is funded by your customers’ payments rather than from your own cash reserves. It typically doesn’t require hard assets as collateral in the same way a secured loan would.
Will my customers know I’m using invoice finance?
It depends on the type. Invoice factoring is disclosed — your customers know about and deal with the factor. Invoice discounting is confidential
— your customers continue paying you directly and have no visibility of the financing arrangement. Most established businesses with good internal credit control prefer discounting for this reason, though factoring is the more accessible option for smaller or newer businesses.
What businesses are eligible for invoice finance in the UK?
Eligibility requires: being a B2B business that invoices other businesses (not consumers) on credit terms; invoices that are undisputed and for goods or services already delivered
; typically a minimum of £50,000-£100,000 in annual invoiced sales for factoring, or £500,000+ for discounting. Businesses invoicing the NHS or government are often accepted at lower thresholds. Consumer-facing businesses, construction firms with routine retention disputes, and businesses with very high customer concentration may face restrictions.
Conclusion
For UK B2B businesses that invoice on credit terms, invoice finance addresses one of the most persistent and damaging problems small businesses face: the gap between raising an invoice and actually getting paid for it. Done well, it converts an illiquid asset — money owed to you — into working capital within 48 hours, without adding a fixed debt burden to your balance sheet and without requiring the collateral a traditional bank loan might demand.

The case for using it thoughtfully is strong; the case for rushing into the first facility you’re offered without comparing the market is not. The fee structures are detailed, the minimum terms create genuine commitments, and the variation in pricing between providers is large enough to matter significantly over a 12-24 month facility. Take the time to understand the full cost, get quotes from multiple providers (ideally via an independent broker), read the exit terms carefully, and make sure the business you’re trying to fund is genuinely profitable rather than using finance to paper over a structural problem. Done right, though, invoice finance can be exactly the cashflow lever a growing UK business needs — and for sectors where 60-day payment terms are simply the norm, it’s often the most sensible financing structure available.
