What is Invoice Financing?

Customers are the lifeblood of any business. Even if someone only buys from you once, it's one more sale than you started with. In time, strong relationships can form with the customers who keep coming back to you. The more sales you make, the better – right? Sadly, UK SMEs are at risk from invoices that are either paid late or not at all. It can mean cash flow dries up, resources become squeezed, or growth plans stall. Either way, having money tied up in unpaid invoices can be damaging. And that's where invoice finance can prove so effective. An invoice finance facility is a revolving credit line that's based on the value of your outstanding invoices. It means businesses can access much-needed funding against its debtor book – which is generally your major asset. Cash is then made available as soon as the invoices are raised to be reinvested or used to run the business.

Invoice finance is an extremely popular alternative to other commercial financial products. This is because it's taken out against the value of your unpaid invoices. Instead of waiting weeks or months to receive money, this type of funding can offer access to funds almost instantly. So, if your business is looking to unlock some of the money owed by customers, why not speak to a reputable invoice finance provider such as Nucleus? Let our tailored financial solutions help you move forward – not back. Apply for invoice finance with us today and get approved for free.

The different types of invoice financing in the UK

In the UK, a business can choose from two main types of invoice financing. It essentially means that you have options within an option – depending on the level of control you want to retain. It is also worth remembering that lenders won't necessarily offer you both choices.

Invoice Factoring
The lender lets you borrow up to a certain share of the value of your unpaid invoices. You'll also pass over the management of your sales ledger and credit control. Your lender will then receive payment direct from your customers. After costs are deducted, you get the remaining balance. This the type of invoice financing that Nucleus offers, up to £50m depending on the value of your outstanding invoices. It can also leave you free to concentrate on growing your business – rather than running around chasing your unpaid invoices.

Invoice Discounting
Unlike invoice factoring, invoice discounting means you'll keep the credit control responsibilities. You'll pay a fee to your lender, as well as a discount charge. In some respects, this makes it not unlike an overdraft. It may be an option open to specific or more established companies though.

What can Invoice Finance be used for?

SME invoice finance can offer an effective solution to a range of everyday business challenges. Here are just some of the various ways in which your invoice finance can be put to good use:

An invoice finance facility could be an effective way to access funding if your business is owed money from unpaid invoices. You may be the supplier of consumer goods to other companies. Or perhaps you contract services to firms on bigger projects. Either way, if there's money tied up that you can't get at, we may be able to help.

It's worth noting, however, that no form of funding is risk-free. There are certain factors that you'll need to consider – such as whether invoice financing costs are worth it. And you should also make sure you're eligible. For some lenders, that means having a minimum invoice value or company turnover

As effective as invoice finance can be, there are unique restrictions to be aware of. First and foremost, you won't qualify if invoices are issued to consumers – not other businesses.

You'll also need to consider your customer relationships. If your invoice finance company will take on responsibility for collecting your payments, they'll be the ones who interact with your customers. And that can sometimes have an impact on how they interact with your business.

No form of commercial funding is entirely risk-free, but that shouldn't put you off. As long as you're aware of the risks, you can make a fully informed decision about your next step.

−       A credit check will be run when you apply for invoice financing. Even if it's a "no", any checks can leave a mark on your credit report that could have an impact in future.

−       You'll need to consider the long-term fees involved with your invoice finance facility. It could seem like a great short-term option. But what about over time?

−       The all-important question is whether your customer does eventually pay what they owe. If not, your lender could make it your responsibility for any non-payment of an invoice.

Invoice finance can be offered on your entire sales ledger – or just the invoices that you pick and choose. In the case of the latter, this is known as 'selective' invoice financing. It offers a more flexible approach where you can choose the specific invoices you want to forward-fund.

It won't always be available to your business, but can be an option worth considering.

The benefit of selective invoice financing is that you can use it to secure a specific amount of money. At the same time, you keep control of your sales ledger and deal with all those other invoices as normal. 

Our invoice finance facilities start from £100,000. Based on your business size, sales ledger and needs, you could be able to borrow up to £50m against your unpaid invoices.

There are different factors that will determine your invoice financing costs. It can depend on your chosen lender, the agreement signed, how much you borrow, or total ledger value.

At Nucleus, our invoice finance facilities are typically priced at 0.1% to 2% of your turnover. Your price will always be bespoke, however, and that's something you'll find out as you talk with a member of our team. Apply today to find out more.

It is often the case that, with invoice finance, the invoices themselves act as an asset that can be used as collateral. So, we take a charge called a debenture [PH1] as security over them. Depending on the size of your facility and your individual business, more security may be required. This is something that will be bespoke to your situation, however. And it's something that we can talk about as part of the application and onboarding process.

You can ask them any questions you might have, and they'll be more than happy to answer. They can also offer expert business finance advice.

By choosing an invoice financing provider, you'll no longer be the one chasing up payment of an unpaid invoice. It falls to the provider, which means that your customers now have a third party to deal with. But it doesn't need to be a problem. The Nucleus team has a wealth of experience acting on behalf of our clients to collect invoice payments – and we're always conscious of maintaining the strong relationships you've built up over the years. 

The non-payment of an invoice is one of the worst things that can happen as a business owner. It means you're out of pocket for products/services you supplied to a customer in good faith. It can be frustrating and demoralising, but what happens when you're funded on the basis of that payment? Well, there are ways to protect yourself.

Yes – if you're a start-up that sends out invoices in the initial stages of your business journey, it can be possible to offer invoice finance. Nucleus can help start-ups through to established companies. As long as you're eligible and meet our criteria, the option is there for you. If not, why not consider one of our other commercial finance products?

If you'd like to hear first-hand from one of our existing invoice financing clients, we'd be happy to put you in touch. To do so, please just contact our team and they'll arrange it.

Typically, it takes around one month to complete the process.

It'll sometimes be faster than that, but it can be slower at other times. The main hold up when putting an invoice finance facility in place is often due to getting access to documents.

If you choose Nucleus for our invoice finance solutions, please make sure you are transparent with our team. We also ask that you have all your documents readily available to ensure we're able to be as efficient as we can be.

Once onboarded, you'll have access to your funding line within 24 hours.
