Waiting thirty, sixty or even ninety days to get paid on a large invoice can leave a genuinely profitable business short of the cash it needs right now, a common cause of the cash flow problems many small businesses face. Invoice factoring turns that gap into working capital by selling the unpaid invoice to a specialist provider for an upfront advance, though it comes with a clear trade-off worth understanding before signing anything.
This guide explains how invoice factoring works in the UK, what it costs, how it differs from invoice discounting, and which businesses tend to benefit most.
What Invoice Factoring Actually Is
Invoice factoring is a form of invoice finance where a business sells its outstanding B2B invoices to a factor at a small discount, in exchange for an immediate cash advance. The legal mechanism behind this, under UK law, is the assignment of receivables, meaning you transfer your right to be paid under the invoice to the factor, who then steps into your shoes to collect it.
How the Process Works, Step by Step
Application and Due Diligence
The process typically begins by selecting a factoring provider and submitting an application with financial documents, such as accounts receivable ageing reports and customer details. The provider assesses the creditworthiness of both your business and your customers, since their ability to pay matters as much as yours.
Agreement and Invoice Submission
Once approved, you enter a factoring agreement and submit outstanding invoices for verification. The factor then advances a percentage of the invoice value, typically 80 to 90%, sometimes up to 95% depending on the provider and your customer base.
Collection and Final Settlement
The factor takes over credit control and contacts your customers directly for payment, which means your customers will know a factoring provider is involved. Once the customer pays in full, the remaining balance is released to you, minus the provider’s fees.
A Worked Example
Say you issue a £20,000 invoice. You sell it to a factoring provider, who advances 85% upfront, giving you £17,000 immediately. If the provider charges a 6% fee for the 30 days it takes your customer to pay, that works out to £1,200. Once the customer pays in full, you receive the remaining 15%, £3,000, minus the £1,200 fee, leaving you with £1,800 from that final payment on top of the initial advance.
What Invoice Factoring Actually Costs
Costs are generally made up of two elements: a service fee, charged as a percentage of turnover for managing collections, and a discount charge, effectively interest on the funds advanced. Combined, these often work out in the range of 1.5% to 5% for the discount element, plus a separate 1% to 2% service fee, though rates vary considerably by provider, customer risk, and contract terms.
Recourse Versus Non-Recourse Factoring
Under recourse factoring, which accounts for the large majority of UK arrangements, your business remains liable if a customer fails to pay, and you must repay the advance. Under non-recourse factoring, the provider absorbs the loss if a customer becomes insolvent, though this greater protection typically comes at a higher cost.
Invoice Factoring Versus Invoice Discounting
With factoring, the provider manages your sales ledger and collections directly, and your customers are usually notified to pay the factor. With invoice discounting, you continue collecting from customers yourself, the arrangement is often confidential, and the finance provider sits more in the background. Discounting tends to suit businesses with an established finance function, while factoring suits smaller businesses wanting collections support as well as funding.
Comparing Invoice Factoring and Invoice Discounting
| Factor | Invoice Factoring | Invoice Discounting |
|---|---|---|
| Who collects payment | The factor, directly from your customer | You, as normal |
| Customer awareness | Usually notified | Often confidential |
| Best suited to | Smaller businesses wanting credit control support | Businesses with an established finance function |
| Typical cost | Generally higher | Generally lower |
Who Invoice Factoring Genuinely Suits
- B2B businesses that invoice on credit terms to larger, creditworthy customers
- Newer businesses or start-ups that cannot yet secure conventional bank lending
- Businesses with multiple customers, since lenders prefer risk spread across several accounts rather than concentrated in one or two
- Businesses comfortable with customers knowing a third party is involved in collections
- Businesses needing working capital quickly rather than waiting on a slower loan approval process, such as negotiating a traditional business loan
Risks and Downsides to Weigh
- Customers may assume the business is struggling financially once they see a factor involved
- Fees can be considerably higher than other forms of business finance
- Under recourse arrangements, you remain liable if a customer simply does not pay
- Businesses with only a handful of clients may not qualify, since lenders prefer spread risk
- An aggressive factor’s collection approach could damage otherwise good customer relationships
Checking a Provider’s Credentials
Invoice factoring itself is not regulated in the same way as consumer lending, but most established UK providers are authorised and regulated by the Financial Conduct Authority for related activities. Checking a provider’s regulatory status and industry membership, and comparing more than one provider rather than accepting the first headline rate offered, is a sensible starting point before committing.
Frequently Asked Questions
How much of an invoice’s value can a business typically access upfront?
Most UK providers advance between 80% and 90% of the invoice value upfront, with some offering up to 95% depending on the provider and the creditworthiness of your customers.
Will my customers know I am using invoice factoring?
In most standard factoring arrangements, yes, since the factor typically contacts your customers directly to collect payment. Confidential factoring facilities exist for businesses that specifically want to avoid this.
Is invoice factoring only available to established businesses?
No. Because eligibility is based largely on the creditworthiness of your customers rather than your own trading history, invoice factoring is often accessible to newer businesses, sole traders and start-ups that cannot yet secure conventional lending.
What happens if a customer does not pay under a recourse factoring agreement?
Under recourse factoring, which covers the large majority of UK arrangements, your business remains responsible for repaying the advance if the customer fails to pay, unlike non-recourse factoring where the provider absorbs that risk.
Final Thoughts
Invoice factoring can genuinely solve a real cash flow problem for businesses trading on credit terms, turning money already owed into usable working capital within days rather than months. The trade-off, cost, and handing collections to a third party, means it is worth comparing multiple providers and understanding the recourse terms clearly before deciding whether it fits your specific business.
