Invoice Finance UK: How Invoice Financing Works
Cash flow is essential to running and growing a successful business. But even profitable UK companies can experience cash-flow problems when customers take 30, 60 or 90 days to pay their invoices.
Invoice finance in the UK allows eligible businesses to access money tied up in unpaid customer invoices instead of waiting for normal payment terms to expire.
For businesses selling products or services to other businesses, invoice financing can provide a flexible source of working capital that increases alongside sales.
In this guide, we explain how invoice finance works in the UK, the difference between invoice factoring and invoice discounting, typical costs, eligibility requirements and whether invoice financing could be suitable for your business.
Invoice finance is a type of business funding that allows a company to access a proportion of the money owed to it through unpaid customer invoices.
Rather than waiting weeks or months for a customer to pay, the business uses qualifying invoices to access funding from an invoice finance provider.
For example, imagine your business issues a £25,000 invoice with 60-day payment terms.
Instead of waiting 60 days for the money, an invoice finance provider could potentially advance a large percentage of the invoice value much earlier.
Once your customer pays, the remaining balance is settled according to the terms of your finance agreement, after applicable fees and charges.
Invoice finance can therefore help transform outstanding invoices into working capital.
Although providers and facilities differ, invoice financing generally follows a straightforward process.
Your business provides goods or services to another company and issues an invoice.
For example:
Invoice value: £20,000
Payment terms: 60 days
Under normal circumstances, your business would wait up to 60 days to receive the money.
The qualifying invoice is included within your invoice-finance facility.
The provider verifies the invoice and determines the amount available.
The finance provider releases an agreed percentage of the invoice.
For example:
Invoice: £20,000
Illustrative advance rate: 85%
Initial funding: £17,000
Your company can then use the available funds for business purposes rather than waiting for the customer payment.
When the invoice becomes due, the customer makes payment according to the arrangement.
Who collects the payment depends on whether you're using factoring, invoice discounting or another form of invoice finance.
After the customer pays, the remaining balance is released according to the finance agreement, minus applicable fees and charges.
The precise process differs between providers, so businesses should always check the contractual terms.
Invoice factoring is one of the main types of invoice finance available to UK businesses.
With factoring, the finance provider typically advances money against qualifying invoices and also manages customer collections.
This means the factoring company may:
Customers will generally know that a factoring provider is involved because payments may be made directly to the provider.
Factoring can be useful for smaller companies that don't have a dedicated credit-control department.
Invoice discounting also provides funding against unpaid invoices, but the business usually retains responsibility for collecting customer payments.
Your company continues managing its customers and credit control while the provider supplies finance against eligible invoices.
Some invoice-discounting arrangements can operate confidentially, meaning customers may not be aware that invoice finance is being used.
Invoice discounting can be attractive to established businesses that want to retain direct control over their customer relationships.
Although both provide funding against invoices, the main difference is generally who controls customer collections.
Invoice factoring: The finance provider typically manages collections and may communicate directly with customers.
Invoice discounting: Your company generally continues managing collections itself.
Factoring may be more suitable for businesses wanting funding combined with credit-control support.
Invoice discounting may suit businesses with established accounting and credit-control systems.
Not every business wants to finance its entire sales ledger.
Selective invoice finance allows eligible companies to finance particular invoices rather than committing all customer invoices to a facility.
For example, your company might have £150,000 in outstanding invoices but need additional working capital only temporarily.
You could potentially finance one or several qualifying invoices rather than the entire debtor book.
This can provide additional flexibility, although pricing may differ from full-ledger facilities.
Some businesses prefer customers not to know they use invoice financing.
Confidential invoice discounting can potentially allow the business to retain control of customer communications and collections while accessing funding behind the scenes.
Availability depends on the provider and the financial strength of the business.
The biggest reason is usually cash flow.
Consider a growing UK company generating £100,000 in monthly invoices.
Sales are strong, but customers have 60-day payment terms.
The company may therefore have substantial revenue recorded while still waiting for cash to arrive.
At the same time, it needs to pay:
Invoice financing can potentially reduce the gap between making a sale and receiving the customer's payment.
Invoice finance is primarily designed for businesses selling goods or services to other businesses on credit.
This means it is particularly relevant to B2B businesses.
Industries that commonly use invoice finance can include:
Traditional invoice finance is generally less suitable for businesses that primarily receive immediate payments directly from consumers.
Invoice finance can be particularly valuable for small businesses experiencing rapid growth.
Growth often requires money before customers actually pay.
For example, imagine a small company wins a new £100,000 contract.
That's positive news, but fulfilling the contract could require:
If the customer pays 60 days after receiving the invoice, the business may need to finance those costs before receiving its money.
Invoice finance could potentially help bridge that gap.
Some invoice finance providers consider newer businesses.
Because the funding is linked to customer invoices, providers may pay significant attention to the financial strength of the businesses that owe the money.
A startup with established, creditworthy B2B customers could therefore potentially qualify even without many years of trading history.
However, providers will have their own eligibility requirements.
The amount available typically depends on the value of qualifying invoices.
Suppose your company has:
Eligible outstanding invoices: £200,000
If your facility allows an illustrative advance of 85%, funding could potentially reach:
£170,000
However, actual availability depends on the agreement.
Providers may impose limits on individual customers, invoices or the total facility.
The advance rate is the percentage of an eligible invoice that the provider initially makes available.
For example:
Invoice value: £40,000
Illustrative advance rate: 85%
Initial funding: £34,000
The remaining balance would be handled according to the agreement once the customer pays, after relevant charges are taken into account.
Advance rates vary according to the provider, facility and risk profile.
There is no single standard price for invoice financing.
Costs depend on factors such as:
Charges can potentially include:
A fee for operating and administering the facility.
A financing charge associated with the money advanced.
Some providers may charge for additional services or particular transactions.
Businesses should ask for a complete breakdown of costs before entering into an agreement.
Don't compare providers using one headline percentage alone.
This depends partly on whether the invoice-finance arrangement is recourse or non-recourse.
With recourse finance, your business generally retains the risk of customer non-payment.
If a customer fails to pay within the agreed period, the business may ultimately have to repay or replace the amount advanced against that invoice.
Certain non-recourse facilities can provide protection against specified customer credit risks, subject to limits, conditions and exclusions.
It is important to understand exactly what is covered.
For example, protection against customer insolvency may not necessarily cover a customer refusing to pay because the invoice is disputed.
A business loan provides a predetermined amount that is generally repaid over an agreed period.
Invoice finance works differently because funding is connected to your outstanding receivables.
As your business generates more qualifying invoices, the amount of finance potentially available can increase, subject to facility limits.
The most appropriate option depends on why the business requires finance.
A business overdraft provides access to additional funds through a bank account up to an agreed limit.
Invoice finance is instead linked to qualifying invoices.
Both can potentially help manage working capital, but businesses should compare:
There are several reasons businesses consider invoice financing.
Instead of waiting weeks or months for customers to pay, businesses can potentially access some of the invoice value earlier.
Growing sales can require additional working capital.
Invoice finance can potentially provide funding that increases alongside eligible invoiced sales.
Improved cash flow may help businesses pay suppliers without waiting for customer payments.
Businesses with large payroll obligations may use invoice finance to smooth timing differences between paying employees and receiving customer payments.
Factoring can provide additional assistance collecting customer invoices.
Businesses can potentially offer customers commercially attractive payment terms without having to wait the full period for access to cash.
Invoice finance isn't appropriate for every business.
Potential disadvantages include:
Financing reduces the amount of revenue ultimately retained from invoices.
Factoring companies may communicate directly with your customers.
Some facilities have minimum terms, minimum charges or notice periods.
Not every customer or invoice will necessarily qualify.
Providers may limit funding where a very large proportion of invoices relates to one customer.
Accurate invoices and accounting records are essential.
Providers may ask for information including:
Requirements depend on the provider and size of the proposed facility.
An aged debtor report shows which customers owe your company money and how long their invoices have been outstanding.
It typically divides unpaid invoices into categories such as:
Current
1–30 days overdue
31–60 days overdue
61–90 days overdue
90+ days overdue
Invoice finance providers can use this information to evaluate the quality of a company's receivables.
The application process will vary, but businesses can generally expect the following steps:
Businesses should compare several providers where practical.
The cheapest-looking facility isn't necessarily the best.
Before selecting a provider, consider:
Ask the provider to illustrate the total cost using your expected monthly invoice volume.
Good financial management can make your business more attractive to invoice finance providers.
Consider:
Providers generally prefer invoices that are clear, valid and unlikely to become disputed.
Invoice finance could be worth investigating if your company:
It may be less suitable for businesses receiving most payments immediately from consumers.
Invoice finance allows eligible businesses to access funding based on unpaid customer invoices rather than waiting until the normal payment date.
A provider advances a percentage of qualifying invoice value. Once the customer pays, the remaining amount is handled according to the agreement after applicable fees and charges.
Invoice factoring combines funding against invoices with customer payment collection and credit-control services.
Invoice discounting allows businesses to access funding against invoices while usually retaining responsibility for collecting customer payments.
Invoice finance is a form of business finance based on receivables and operates differently from a conventional fixed-term business loan.
Potentially, yes. Many small B2B businesses use invoice financing to improve working capital.
Potentially. Eligibility depends on the provider, the quality of the invoices and the creditworthiness of customers, among other factors.
With factoring, customers may know because the provider manages collections. Certain invoice-discounting arrangements can be confidential.
The outcome depends on the facility's recourse terms and the reason for non-payment.
Invoice finance in the UK can provide businesses with a flexible way to unlock money tied up in unpaid customer invoices.
Rather than waiting 30, 60 or 90 days for customers to pay, eligible businesses may be able to access a proportion of their invoice value much earlier.
This can help improve working capital, pay suppliers, meet payroll and finance growth.
However, invoice financing has costs and contractual obligations.
Before choosing a provider, compare advance rates, service fees, financing charges, contract periods, recourse terms and credit-control arrangements.
For businesses with reliable B2B customers but long payment terms, invoice finance can be a useful alternative to relying entirely on traditional business loans or overdrafts.
