What is Invoice Financing?

If your business is looking into borrowing money against the amounts due from your customers, then you should consider our invoice finance solutions here at Nucleus.

Invoice finance is a revolving credit line that is based on a company’s outstanding invoices in its debtor book and sales ledger. This type of financing allows businesses to access funding against its debtor book, which is generally the company's major asset. Cash is then available as soon as invoices are raised to be reinvested or used to run the business.

Invoice finance is an extremely popular alternative financial product, as it is taken out against the value of a company’s unpaid invoices. Instead of a business being made to wait months to receive money, it can apply for this type of funding from reputable invoice finance providers such as Nucleus and get access to funds almost instantly. If businesses find themselves unable to cope due to large amounts of money being tied up in unpaid invoices, they can turn to us for help

Our invoice finance facilities start at £100,000 and you can borrow up to £50m.

Usually with invoice finance the invoices themselves are an asset, so we take a charge called a debenture as security over them. Dependent on the size of your facility and your individual business, additional security may be required – but this is negotiable and bespoke.

We would be happy to put you in touch with an existing client. Please just get in touch with one of our team and they can arrange it.

Typically, it takes around one month to complete the process. Sometimes it is faster than that, and other times slower. The main hold up is often due to getting access to documents. When you come to Nucleus for our invoice finance solutions, please make sure you are transparent with our team and have all your documents readily available to ensure efficiency. Once onboarded, you will have access to your funding line within a day.

At Nucleus, we take the time to understand a business’ story – and that includes turnaround situations. We are highly experienced in helping companies to recover and understand that for any business, it’s not always smooth sailing. The best thing to do is to be totally honest. We can work closely with you and your insolvency practitioner, and if we feel it is viable – and a sound recovery strategy is being proposed – we will offer and tailor a solution to support your business to a more positive future.

One of our experts will give you an initial call to establish the potential for Nucleus to support you. Following on from that, they will arrange a convenient time to come to your business for a site visit. This is not only a great opportunity for us to get to know you and your business, but it will also give you the chance to ask any questions that you might have about invoice finance, whilst we learn how you operate and look at the relevant documents.
