Ever struggled whilst waiting for customer payments while your business expenses pile up? You’re not alone. That’s where Invoice finance can become a useful tool as it lets your business tap into the funds thats owed by your customers owe you. It’s a straightforward solution to one of the biggest headaches small businesses face – keeping steady cash flowing through your accounts whilst customers take their time to pay.

Timing can be a real strain to your business finances. Your payment terms mean you have to wait for the income, but your outgoings are going out quicker. With invoice finance you’re essentially using those unpaid invoices as assets to release funds so you can cover your day-to-day costs, pay your suppliers promptly and continue to operate.

Throughout this guide we’ll help you figure out if this solution is a good fit for your business, break down the different types available, the costs and the important bits you should weigh up.

Why Cash Flow Problems Happen

Cash flow is a primary area of concern for all businesses and the problem plagues many small businesses, even when you’ve got a rock-solid business model. Getting to the root causes helps you spot where invoice finance might be just what you need to keep money flowing smoothly.

Late payments and long invoice terms

Late payments are absolutely crippling for small businesses across Britain. It’s thought almost half of all invoices sent out by small businesses aren’t paid on time. This creates serious holes in your working capital that can be hard to fill.

The UK has developed quite a problematic culture around late payments and it’s not just about forgetful clients. Large corporations often take advantage of their position during negotiations, leaving smaller suppliers little choice but to accept painfully extended payment terms. 

These payment delays don’t just affect one business, they cascade through entire supply chains. When someone pays you late, you’re often forced to pay someone else late. The issue contributes to holding back business growth and ultimately costs businesses.  

Seasonal sales and inconsistent income

Seasonal fluctuations hit many small businesses hard throughout the year. These ups and downs might be predictable but they create cash flow cycles that need careful handling and some sectors feel this more than others. Tourism, agriculture, construction, and retail businesses typically ride the seasonal rollercoaster. 

This stop-start cash flow pattern makes planning your finances properly a huge headache as you fluctuate between healthy profits and a virtual standstill. If you’re caught unprepared, these fluctuations can lead to unnecessary debt, missed chances to grow, and serious financial pressure.

What Is Invoice Finance and How Does It Work?

Invoice finance gives businesses with outstanding customer invoices a way to sort out cash flow issues as it allows you to borrow money against unpaid invoices.

Invoice finance definition and meaning

At its core, invoice finance (sometimes called accounts receivable financing or receivables financing) is simply a form of short-term borrowing where your business uses unpaid customer invoices as collateral. You’re unlocking money that’s technically already yours but stuck in your sales ledger, giving you immediate access to working capital without the wait for payments. It provides a bespoke solution over a standard loan, which you can utilise for just the period of cash flow constraints. 

The steps of invoice financing

Each lender will have variations, but the backbone of the process is:

  1. You provided a service or product and invoiced a customer for payment
  2. You submit the same invoice to your invoice finance lender
  3. The lender advances you a percentage of the invoice value (up to around 95%)
  4. Either you or the lender collects payment from customers
  5. You receive the remaining balance minus the lender’s fees

Throughout this arrangement, your unpaid invoices act as the main security. This means lenders are very focused on your customers ability to pay and your business credit history can be less of a factor, unlike standard lending criteria.

How fast can you access funds?

Once you are set up with an invoice finance partner, speed is a key advantage of invoice finance. Many providers offer systems that link directly with your accounting software, making the whole thing nearly seamless,  upload invoices and access funds with minimal fuss

Types of Invoice Financing Explained

There are variations of invoice finance available. These distinct options are designed to suit different business scenarios and preferences. Understanding these variations will help you pick the most suitable solution for your particular situation.

Invoice factoring: when the lender collects

With invoice factoring, you’re essentially selling your unpaid invoices directly to a factoring company that fronts you something like 70-90% of the invoice value right away. The key distinguishing feature is that the factoring company takes over responsibility for collecting payment from your customers. After your customer settles, you receive the balance minus the lender’s fees.

The factoring company handles all the credit control and collections legwork, which frees up your time and resources for other pressing matters. There’s a trade-off, though, your customers will have visibility if you’re using factoring and this might not be positive for some of your business relationships.

Invoice discounting: keeping control of collections

Invoice discounting works on similar principles but with the difference that you stay in control of your credit control processes and customer relationships. The invoice finance provider still lends against your outstanding invoices (again approximately 70-90%) but remains invisible to your customers.

This confidentiality could be preferential if you’re running an established business and concerned about how external financing might be perceived. Throughout, your customers continue dealing directly with you and that’s why it’s also termed  as “confidential invoice discounting.”

Selective invoice finance: flexibility for occasional needs

Unlike factoring or discounting arrangements that apply a blanket approach to your sales ledger, selective invoice finance (sometimes called spot factoring) lets you cherry-pick individual invoices to finance. You decide exactly which invoices to fund rather than committing to a comprehensive solution.

This flexibility is for businesses that only occasionally need a cash flow boost or those wanting to test invoice financing before diving in completely. It also is a solution for businesses with a handful of large invoices creating temporary gaps in cash flow.

Is Invoice Finance Right for Your Business?

Working out whether invoice finance fits your business isn’t entirely straightforward. Understanding eligibility and weighing up the pro’s and con’s against your unique business situation will take a bit of research. 

Eligibility criteria and business types

Invoice finance isn’t for everyone. It primarily serves businesses that deal with other businesses (B2B) on credit terms. Most providers want to see some trading history, they are looking for proof you consistently get paid for the invoices you send out. Requirements vary between lenders and factoring and discounting versions are likely to be a better match for businesses with a good turnover. A smaller operation might find selective invoice finance more suitable.

The quality of your invoices matters. Lenders will scrutinise how likely your customers are to pay so your invoices must be solid and collectable. 

Pros and cons to consider

Invoice finance key advantages:

  • Improved cash flow – Get quick access on up to 95% of invoice value
  • Asset utilisation – Make use of assets sitting on your balance sheet
  • Flexibility – By keeping pace with your cash flow needs
  • Less dependence on credit history – Eligibility shifts some of its focus onto customer payment reliability. 

Key considerations:

  • Higher costs – You’ll likely pay more in fees than you would in interest on traditional loans
  • Minimum contracts – Many providers will want commitment for a set period
  • Customer perception concerns – Particularly with factoring arrangements
  • Disputed invoices – Can see a clawback of released funds. 

When to choose invoice finance over other options

Invoice finance works for businesses struggling with gaps in cash flow caused by delayed payments. Unlike traditional loans that fund specific projects or purchases, invoice finance provides capital linked to your invoicing activity.

Invoice finance can be approved within 24 hours, providing a quick engagement of service while regular business loans might take weeks. If your business hasn’t built up much credit history you’ll likely find invoice finance more accessible since approval hinges more on your customers’ payment reliability.

Invoice finance fits when your fundamental need is to speed up cash flow rather than take on more debt. It’s designed for when you’re generating plenty of sales but the gap between delivering goods and getting paid is causing you headaches.

Conclusion

Getting to grips with invoice finance gives you solutions for your business’s cash flow management issues. Late payments or seasonal dips can be managed and planned with invoice financing.Its rapid turnaround and adaptability make it worth considering if you’re growing your business, but remember it is more costly than other loans.  

Your choice between factoring, discounting or selective invoice finance really boils down to what suits your particular circumstances and assessment of how it could be perceived by your customer base if you choose one of the visible options. 

Before diving in, take the time to properly assess your business model, how your customers typically pay, and where you’re heading growth-wise. The success of invoice finance hinges largely on having customers who actually pay up in the end and keeping your invoicing documentation to a high standard. Invoice finance is a practical option for companies battling extended payment terms or seasonal cash flow nightmares.
