What Is Invoice Finance and How Does It Work?
Invoice finance is a funding solution that allows businesses to unlock cash tied up in unpaid invoices, providing faster access to working capital rather than waiting 30, 60 or even 90 days for customers to pay. For many UK SMEs, invoice finance is a flexible way to manage cash flow and fund growth without taking on traditional debt.
When you use invoice finance, a provider advances you up to 100% of an invoice's value within 24-48 hours. Once your customer pays the invoice in full, the provider releases the remaining balance minus their fees. The two main types of invoice finance are:
Invoice Factoring: The provider manages your sales ledger, chases payments, and handles credit control on your behalf. Your customers are notified that a third party is collecting payment.
Invoice Discounting: You retain full control over your sales ledger and customer relationships. The arrangement remains confidential, and you continue to collect payments yourself.
Both options serve the same core purpose: converting unpaid invoices into immediate cash. However, they differ in level of control, confidentiality, cost, and suitability depending on your business size and needs.
Invoice Finance Costs Explained
Invoice finance pricing in the UK typically consists of two main components, plus potential additional charges. Understanding these elements is crucial when comparing providers.
Service Fee (Admin or Factoring Fee)
The service fee covers the administrative work involved. For invoice factoring, this includes credit control, chasing payments, and sales ledger management. For invoice discounting, the fee is lower because you retain control of collections.
Typical Range: 0.5% to 3% of your monthly invoiced turnover, though it can be as low as 0.2% for larger businesses or as high as 4.5% for start-ups.
What Influences It: Your annual turnover, invoice volume, sector risk, and whether you choose factoring (higher) or discounting (lower).
Discount Fee (Interest Rate or Funding Charge)
The discount fee is the interest charged on the cash advance. It's calculated daily on the amount you've drawn and is typically expressed as an annual percentage over the Bank of England’s base rate.
Typical Range: Base rate plus 1.5% to 6% annually (e.g. if the base rate is 3.75%, the total rates would range from approximately 5.25% to 9.75%).
How It's Charged: Interest accrues daily and is billed weekly or monthly. The longer your customer takes to pay, the higher the discount fee you incur.
Additional Charges to Look Out For
Setup or Joining Fees: One-off charges to establish the facility, usually 1-2% of the agreed facility limit.
Minimum Monthly Fees: If your invoice volume falls below a pre-agreed threshold, you may be charged a minimum monthly fee.
Termination Fees: Costs for ending the contract early.
Selective or Spot Invoice Fees: If you finance individual invoices rather than your entire ledger, fees typically range from 3% to 5% of the invoice value.
Factoring vs Discounting: Rate Comparison
Choosing between invoice factoring and invoice discounting affects both cost and control. Here's how the two compare:
Feature | Invoice Factoring | Invoice Discounting |
Service Fee | 0.75%-4.5% of turnover | 0.2%-1.5% of turnover |
Discount Rate | Base rate + 1.5%-5% | Base rate + 1.5%-5% |
Credit Control | Provider handles | You manage |
Confidentiality | Customers notified | Confidential |
Typical Minimum Turnover | £100,000+ | £250,000-£500,000+ |
Best For | Startups and smaller SMEs | Established or larger firms |
Factoring generally costs more due to the credit control service, but it saves you the staffing and time required to chase payments. Discounting is cheaper overall but requires you to have robust internal processes and a strong relationship with your customers.
What Does Invoice Finance Cost?
To help you understand what invoice finance might cost your business, here are three examples based on typical UK SME scenarios:
Small Construction Business (£250,000 Annual Turnover)
Product: Invoice Factoring
Service Fee: 2.5% of turnover = £6,250 annually (£520/month)
Discount Fee: Base rate (3.75%) + 3.5% = 7.25% on average drawn balance of £40,000 = £2,900 annually (£242/month)
Total Annual Cost: £9,150 (approximately 3.66% of turnover)
Mid-Sized Recruitment Agency (£1,000,000 Annual Turnover)
Product: Confidential Invoice Discounting
Service Fee: 0.75% of turnover = £7,500 annually (£625/month)
Discount Fee: Base rate (3.75%) + 2% = 5.75% on average drawn balance of £150,000 = £8,625 annually (£719/month)
Total Annual Cost: £16,125 (approximately 1.61% of turnover)
Healthcare Supplier (£500,000 Annual Turnover)
Product: Invoice Factoring
Service Fee: 1.5% of turnover = £7,500 annually (£625/month)
Discount Fee: Base rate (3.75%) + 2.5% = 6.25% on average drawn balance of £80,000 = £5,000 annually (£417/month)
Total Annual Cost: £12,500 (approximately 2.5% of turnover)
These examples illustrate how costs can vary significantly based on turnover, product type, and the amount you draw. Higher-turnover businesses typically benefit from lower percentage fees and better negotiating power.
How to Choose the Right Invoice Finance Provider
With dozens of providers in the UK market, trying to select the right one can feel overwhelming. Here's a step-by-step approach to finding the best fit for your business:
1. Match the Product Type to Your Business Needs
Choose Factoring If: You're a startup or smaller SME, you lack in-house credit control resources, or you want to outsource collections.
Choose Discounting If: You have turnover above £250,000, want to keep the arrangement confidential, and have the internal resource to manage your sales ledger.
2. Compare the Total Cost of Finance
Look beyond the discount rate. Calculate the combined impact of service fees, discount fees, setup charges, and any minimum monthly fees. Request a full cost illustration from each provider based on your details.
3. Check Advance Rates and Funding Limits
Providers typically advance 80-95% of the invoice value. A provider offering 95% will give you significantly more upfront cash than one offering 80%, which can make a material difference to your working capital.
4. Understand Eligibility
Some providers specialise in specific sectors (e.g. construction, recruitment or healthcare), while others have broad industry coverage. Check that the provider has experience in your industry and will accommodate your invoice terms and customer base.
5. Review Contract Terms and Flexibility
Contract Length: Look for flexibility. Some providers require 12-month minimum terms, while others offer rolling monthly contracts.
Termination Fees: Understand the cost of exiting early.
Selective Finance: If you don't want to finance all invoices, ensure the provider offers selective or spot invoice finance.
6. Assess Customer Service
Modern invoice finance providers usually offer online portals, real-time reporting, and mobile apps. Strong customer service and dedicated relationship managers can make day-to-day management far smoother.
7. Use a Comparison Platform
Platforms like BusinessComparison can help you compare multiple providers quickly, ensuring you get competitive quotes and understand the full range of options available. By reviewing several offers, you can identify the best combination of cost, flexibility, and service for your needs.

Funding Option | Speed | Typical Cost | Best For |

1-2 weeks | 4%-15% APR | One-off capital investments | |
1-3 days | 1.2-1.5 factor rate | Retailers or hospitality with consistent sales | |
1-2 weeks | 3%-8% APR | Purchasing equipment or vehicles |

Tips to Reduce Invoice Finance Costs

Improve Customer Creditworthiness: The better your customers' credit profiles are, the lower your risk and your fees. Aim to work with larger, more established clients.
Increase Invoice Volume: Higher volumes can unlock lower percentage fees.
Reduce Days Outstanding: The faster your customers pay, the lower your discount fees. Consider offering early payment incentives.

Frequently Asked Questions
How quickly can I access invoice finance?
Most providers can approve your invoice finance application and release the first advance within 24-48 hours.
Though full onboarding and due diligence could take 1-2 weeks for a full facility setup.
Do I need to notify my customers?
With invoice factoring, yes. Customers are notified that a third party is collecting payment.
With confidential invoice discounting, no. The arrangement remains private, and you continue to collect payments.
What happens if my customer doesn't pay?
Most invoice finance is offered on a 'recourse' basis, meaning you're responsible if a customer doesn't pay. Some providers offer 'non-recourse' or bad debt protection (at an additional cost), where they assume the credit risk instead.
Can startups use invoice finance?
Yes, many providers work with startups. However, you'll typically need a minimum turnover of £100,000 and creditworthy B2B customers.
Some UK providers specialise in supporting early-stage businesses.
Is invoice finance cheaper than a business loan?
It depends on your circumstances. Invoice finance can be more expensive on an APR-equivalent basis, but it offers greater flexibility, quicker access to cash, and scales with your sales, making it ideal for growing or seasonal companies.
How is invoice finance different from a loan?
A loan provides your business with a lump sum, which must be repaid over a fixed term with interest.
Whereas invoice finance is a revolving facility tied to your invoices, with no fixed repayment schedule. You draw and repay as invoices are raised and paid.
