Best UK small business invoice factoring companies

The top invoice factoring companies for small businesses in the UK are:

Optimum Finance

Optimum Finance logo (invoice factoring)

 SME specialist

Bespoke solutions

No minimum turnover



It may have only been founded in 2017, but Optimum Finance has already made some serious waves in the world of invoice finance, and it issued £60.9m of business funding in 2018.

The team behind Optimum boasts decades of business finance experience, and the lender explicitly bills itself as an SME specialist that offers bespoke solutions to a wide range of UK businesses.

One key selling point is that, unlike many lenders, Optimum Finance has no minimum turnover requirement, making it a great choice for startups that need extra funding.

It offers rapid access to up to 85% of the invoice amount, and, for an extra fee, can provide businesses with debtor protection.

This compensates Optimum clients in the event that their customers encounter financial difficulties and are unable to pay what they owe.

Invoice factoring customers also get access to E3, a real-time online system that means you can monitor your Optimum Finance account and sales ledger 24/7.

Unlike some lenders, Optimum Finance does not have a presence on a customer reviews website but it does have a rating of 4.6 on Google (albeit from 12 reviews). These reviews praise the company for being friendly, efficient and responsive.

Verdict: Optimum Finance is a great fit for startups and other small businesses.


GapCap logo (invoice factoring)Flexible provider

✅ No contract

✅ Speedy application process




If you want to use invoice finance occasionally rather than making a firm commitment, then GapCap could be the ideal solution.

Through what it calls selective invoice finance, GapCap allows companies to raise money on upcoming invoices on an ad hoc, contract-free basis, a refreshing change from the binding contracts required by some providers.

The lender offers an advance of up to 85% of the invoice value and prides itself on a speedy application process, with most clients receiving an offer within 24 hours of application.

The company assigns a dedicated account manager to each client and, perhaps as a result, scores very highly on customer service, with an average of 4.8 on Trustpilot.

This is based on 78 reviews and the dedication and professionalism of the GapCap team comes up again and again – with one reviewer noting that he has his account manager on WhatsApp, and he replies day and night.

One thing to note is that, to be eligible for selective invoice finance, companies must have six months of trading history, so it’s not available to very early-stage startups.

Verdict: As long as you have six months of trading history, GapCap offers a great flexible take on invoice factoring that’s ideal for small businesses.

Inspired Finance

Inspired Finance - best invoice financeBusiness finance broker

Hands-on service

Compare a range of providers

Unlike the other companies on this list, Inspired Finance is not a lender. Instead, it’s a broker that specialises in invoice finance and other types of business funding.

It was founded in 2016 and, through the lenders on its platform, offers advance rates up to 100% and low rates from 0.1% (although this is obviously highly dependent on the circumstances of your business).

And it quickly made an impact, being shortlisted as Invoice Finance Broker of the Year at the 2019 Business Moneyfacts Awards.

Inspired Finance prides itself on providing a bespoke service – the company assesses your business’ specific requirements and introduces you to the most suitable funding option for your needs.

There’s no obligation and no risk, making this a good choice for businesses that need a bit of expert help on their funding journey.

Verdict: Inspired Finance is a great option for small businesses that need a helping hand with their invoice factoring search.

Bibby Financial Services

Bibby Financial Services Logo (Invoice Factoring)Over 35 years of funding experience

Global coverage

Provides funding to over 7,000 businesses

Bibby Financial Services is one of the big hitters in the world of invoice finance, with a great track record and strong industry expertise in a variety of areas.

They offer bespoke funding solutions, and advance up to 100% of the invoice value within 24 hours.

The discount fee (essentially the interest you are charged on the advanced invoice) is typically 1-3.5% of the invoice amount, while the service fee (the amount you are charged for the invoice factoring service) is between 0.5% and 3.2% of your company’s annual turnover.

Bibby really stands out thanks to its scale – it provides funding to over 7,000 businesses and has experience and insight in sectors including construction, recruitment, manufacturing, and wholesale.

It also has an unrivalled track record. The company was founded in 1982, and boasts that it has been funding its longest-standing client since 1989.

Having stayed in business for over three decades, it’s no surprise that Bibby has an excellent reputation when it comes to customer service.

It has an average rating of 4.7 on Trustpilot, and is praised for its professionalism and hands-on approach, with some reviewers discussing how they have used the company for over a decade.

Bibby offers its services with an unlimited duration on a rolling contract, gives customers access to a 24/7 online account service, and offers Bad Debt Protection, which – for an extra fee – means Bibby clients won’t be out of pocket if one of their payees encounters financial difficulties.

Given its dominant market position, Bibby can afford to be selective with its client list.

Businesses have to have an annual turnover of over £100,000 to be eligible, so smaller SMEs may need to look elsewhere for their business funding.

Verdict: Bibby’s scale, track record, and industry expertise makes it a great choice for larger SMEs.

Hitachi Capital UK

Hitachi Capital UK logo (Invoice Factoring)Award-winning provider

One-fee structure

6-month trial period

When looking at invoice factoring from Hitachi Capital UK, one thing immediately stands out.

They were named the Best Factoring and Invoice Discounting provider at the 2019 Business Moneyfacts awards, the UK’s largest business finance awards ceremony. So they must be doing something right.

They currently support over 800 SMEs and have 25 years experience of funding businesses.

Hitachi Capital UK advances up to 90% of the invoice value and offers two fee structures.

Their standard invoice factoring product operates on typical terms, with a service fee that is a percentage of company turnover, and a discount fee that is a percentage of the amount lent.

However, Hitachi also offers a product called Inspired Cashflow, a comprehensive invoice factoring solution that charges a simple fee of between 0.45% and 5% of the company’s annual turnover.

This means no hidden fees and no set up costs, and is a great option for any SME that is put off by the complicated fee structures of other providers.

Refreshingly, Hitachi is one of the few invoice factoring companies to offer a six-month trial period to see if invoice factoring is the right fit for your small business.

After this, you’ll be offered a rolling monthly contract, perfect for SMEs put off by lengthy contracts.

This provider also scores highly for customer service, with an average Feefo score of 4.3. However, there are only seven reviews left during the past year, and one of these criticises the lack of communication between different departments at the company.

Also remember the usual caveat with Feefo, customers can only leave a review if invited to do so, so the company being reviewed has more control over the process than with sites like Trustpilot.

In terms of eligibility, Hitachi states that its services are suitable for businesses with a minimum annual turnover of £50,000.

However, they also stress that they assess each business individually, and will consider startups, especially if they are homeowners.

Verdict: Hitachi Capital is a great option for a variety of SMEs. The one-fee Inspired Cashflow product provides welcome clarity, and a six-month trial period means it’s ideal for SMEs that want a low-risk way to try invoice factoring.

Skipton Business Finance

Skipton Business Finance Logo (Invoice Factoring)Clear online fees

Dedicated relationship manager

Variety of products

Skipton Business Finance was founded in 2001 but is part of Skipton Building Society, a financial institution that’s been going since 1853.

This, Skipton argues, gives it a different perspective, with the company stating that it’s “focussed on understanding its clients’ businesses and assisting in creating wealth and jobs in the regions, rather than purely for profit.”

They advance up to 90% of the invoice value, and give each client a dedicated relationship manager.

A wide variety of invoice finance options are available, including My White Label, a business solution that combines invoice finance with professional credit control in a completely confidential package that will leave your customers none the wiser.

Another interesting option is Skipton Select, which offers what Skipton calls interest-free invoice factoring.

Essentially, you simply pay a flat fee that’s a percentage of your annual turnover and Skipton is admirably up front about these, publishing the following table on its website.

Skipton is also open to startup businesses. It lists no minimum turnover and has a specific section on its website that addresses Invoice Finance for a New Start Business.

Verdict: Skipton Select is a good option for SMEs, with a clear fee structure, a variety of products, and a strong focus on relationships.

How do I choose the best invoice factoring company for my small business?

What to look out for when choosing an invoice factoring company?

  • Clear fees – You need to know exactly what you are and aren’t paying for, as well as if there any extra fees that may affect the total cost of your invoice factoring service
  • Transparent Ts and Cs – Like any financial product, make sure you go through the terms and conditions with a fine tooth comb, you don’t want to be tripped up by an unexpected clause down the line
  • Credit control – Many providers offer this as standard but it’s worth checking – professional help assessing the credit worthiness of your customers can make a big difference to your small business
  • Bad debt protection – This is generally provided for an extra fee but is well worth considering – it means you’ll be covered if your clients experience financial difficulties and can’t pay their debts
  • A dedicated relationship manager – This is crucial – when you have a problem, you want to to deal with someone who knows your company, not a telephone switchboard
  • Industry expertise – Look for a factoring company that has experience funding businesses like yours, and understands the industry in which you operate
  • Excellent customer service – To get a good idea of the level of service you can expect, check customer review sites like Trustpilot and Feefo

Invoice factoring companies: making the best choice for your business

There’s no doubt that finding the right invoice factoring solution can make a huge difference to your small business.

However, there’s more to picking the right provider than just choosing the one that provides the lowest fees.

Carefully consider the pros and cons of providers, including the quality of their general customer service, whether you’ll be assigned a dedicated account manager, their level of expertise in your sector, and whether they are used to the challenges associated with small business finance.

If you need invoice factoring for your construction or recruitment business, then make sure to check out our in-depth guides to construction finance and the best recruitment factoring companies.

Invoice factoring company FAQs?

Will my customer know I’m using a factoring company?

This depends on the invoice factoring company you choose, and your arrangement with them. Many providers do have a confidential invoice factoring product that keeps their involvement hidden.

However, this may come with higher fees than their standard offer. An invoice factoring company openly chasing your customers may also encourage them to pay quicker, so make sure you weigh up the pros and cons of confidential invoice factoring before making a decision.

Is invoice factoring available to startup businesses?

This depends on the requirements of the provider. Some have a minimum annual turnover but others assess each business on a case-by-case basis.

If your business is a startup without a trading history, you’ll need to pay high fees and may also have to put up an asset (such as your home) to secure invoice factoring funding.

Can invoice factoring companies also offer invoice discounting?

The majority of invoice factoring companies also offer invoice discounting. The key difference is that, with invoice discounting, the business receiving funding retains control of things like payment chasing and invoice processing.

Because of this, it’s much easier to hide the involvement of your invoice finance partner, but the extra work involved means invoice discounting is often better suited to larger businesses.
