Invoice factoring: how it works and when to use it

Invoice factoring allows businesses to unlock cash tied up in unpaid invoices. By selling invoices to a third-party provider, you can access funds quickly instead of waiting weeks or months for customers to pay.

For UK businesses dealing with long payment terms or uneven cash flow, invoice factoring can provide short-term stability. This guide explains how invoice factoring works, when it makes sense to use it, and the risks to consider before proceeding.

What is invoice factoring?

Invoice factoring is a form of invoice finance where a business sells its unpaid invoices to a factoring company, known as a factor. The factor advances most of the invoice value upfront, then collects payment directly from the customer when the invoice falls due.

Once the customer has paid, the factor releases the remaining balance to the business, minus their fees.

Invoice factoring is commonly used by B2B businesses with agreed payment terms of 30, 60 or 90 days that need faster access to working capital.

How does invoice factoring work in practice?

Invoice factoring follows a straightforward process designed to release cash quickly.

1. You supply goods or services to your customer
2. You raise an invoice with standard payment terms
3. The invoice is sold to a factoring company
4. You receive an advance, typically 70 to 90 percent of the invoice value
5. The factor takes over credit control and chases payment
6. Your customer pays the invoice directly to the factor
7. The remaining balance is paid to you, minus agreed fees

This structure removes delays caused by slow-paying customers and can stabilise cash flow during busy or high-cost trading periods.

Factoring vs invoice discounting: what’s the difference?

While both are forms of invoice finance, there is a key distinction.

With invoice factoring, the factor manages the collection of payment and your customer is aware of their involvement.

With invoice discounting, the invoice remains under your control. You borrow against its value and continue to manage customer payments yourself. Discounting is often confidential and better suited to businesses with strong internal credit control.

Why do businesses use invoice factoring?

The main reason businesses use invoice factoring is speed. It provides fast access to cash without taking on traditional debt.

Factoring is often used to:

• Cover short-term cash flow gaps
• Fund payroll, tax or supplier payments
• Support growth when customers pay slowly
• Reduce pressure on internal credit control teams

Because funds are released against invoices already issued, approval is often quicker than for unsecured business loans.

An example of invoice factoring

Consider a business that raises a £10,000 invoice with 60-day payment terms.

• The factor advances 85 percent upfront (£8,500)
• The factor collects the £10,000 from the customer when due
• Fees of 3 percent (£300) are deducted
• The remaining £1,200 is paid to the business

The business receives most of the cash immediately, rather than waiting two months for payment.

Does invoice factoring affect your business credit score?

Invoice factoring does not usually have a negative impact on your business credit profile. Because it is treated as the sale of an asset rather than a loan, it does not add debt to your balance sheet in the same way as borrowing.

In some cases, improving cash flow through factoring can help a business meet its obligations more reliably, which may support its overall credit position.

Key benefits of invoice factoring

When used appropriately, invoice factoring can be a valuable cash flow tool.

Faster access to cash

Invoices are converted into working capital almost immediately, improving liquidity.

Improved cash flow stability

Factoring smooths income when customers take longer to pay.

Outsourced credit control

The factor manages collections, reducing internal admin and chasing.

Continued trading and growth

Businesses can continue operating and investing even when cash is tied up in receivables.

When invoice factoring may not be the right choice

Invoice factoring is not suitable in every situation.

It may be less appropriate if:

• You have low invoice values or few customers
• Maintaining direct control over customer relationships is critical
• Fees outweigh the cash flow benefit
• You only need funding occasionally rather than continuously

Some businesses prefer short-term loans or revolving credit facilities that provide flexibility without involving third parties in customer payments.

Who is invoice factoring suitable for?

Invoice factoring is primarily designed for B2B businesses. It is commonly used in sectors such as construction, manufacturing, logistics and recruitment.

Most providers require:

• Business-to-business trading
• Agreed payment terms
• A minimum annual turnover, often around £100,000
• A spread of customers rather than reliance on a single debtor

Sole traders, partnerships and limited companies may all be eligible, depending on the provider.

Risks and drawbacks to consider

Before choosing invoice factoring, it is important to understand the potential downsides.

Cost

Factoring fees reduce the total amount you receive from each invoice.

Customer relationships

Your customers will deal directly with the factor, which may not suit all businesses.

Contract commitments

Some providers require long-term agreements, though selective or spot factoring is also available.

Suitability

Factoring works best with higher invoice volumes and values. Smaller businesses may find alternatives more cost-effective.

Alternatives to invoice factoring

Invoice factoring is only one option for managing cash flow. Depending on your needs, you may also consider:

• Invoice discounting, where you retain control of collections
• Business overdrafts, for short-term flexibility
• Short-term business loans, for larger one-off costs
• Revolving credit facilities, offering repeat access to funds
• Asset finance, to spread the cost of equipment or vehicles

The right solution depends on your turnover, margins, cash flow pattern and appetite for third-party involvement.

Choosing the right finance option

There is no single best finance solution for every business. The most effective approach is often to match funding to purpose, using invoice finance for cash flow gaps and other facilities for growth or asset investment.

Working with an experienced broker can help you compare options, understand costs clearly and structure funding that supports your business without unnecessary risk.
