What is invoice factoring?

TL;DR: Invoice factoring is a financial process where a business sells its unpaid invoices to a third party to receive immediate cash. While it improves liquidity, it involves fees and means the factor will manage your customer collections, which carries potential reputational risks.
Managing cash flow is one of the most significant challenges for small and medium-sized enterprises (SMEs) in the UK. When you provide goods or services to other businesses, you often have to wait 30, 60, or even 90 days for payment. This delay can make it difficult to pay staff, invest in new equipment, or cover daily operational costs. Invoice factoring is a popular solution designed to bridge this gap by turning your accounts receivable into immediate working capital.
What is invoice factoring?
At its core, invoice factoring is a type of asset-based finance. Instead of waiting for a customer to settle their bill, you “sell” that bill to a specialist finance provider, known as a factor. The factor provides you with a significant percentage of the invoice value upfront, typically within 24 to 48 hours. Once your customer pays the invoice in full, the factor releases the remaining balance to you, minus a small fee for their service.
Unlike a traditional bank loan, invoice factoring is not necessarily a debt in the conventional sense. You are not borrowing a lump sum to be repaid in monthly instalments. Instead, you are accelerating the payment of money that you have already earned. This makes it an attractive option for businesses that have high creditworthy sales but limited cash on hand.
How the invoice factoring process works
The process of factoring is generally straightforward and follows a specific cycle. Understanding these steps can help you decide if it aligns with your business operations.
- Step 1: Invoicing your customer. You provide your goods or services to a customer as usual and issue an invoice with your agreed payment terms.
- Step 2: Selling the invoice. You send a copy of that invoice to the factoring company. Most modern factors use digital platforms that integrate with your accounting software to make this seamless.
- Step 3: Receiving the advance. The factor verifies the invoice and pays you an initial advance. This is usually between 80% and 95% of the total invoice value.
- Step 4: Collection and credit control. The factoring company takes over the task of collecting the payment from your customer. They will manage the sales ledger and send reminders or make phone calls to ensure the debt is settled.
- Step 5: Final settlement. Once the customer pays the factor the full amount, the factor pays you the remaining 5% to 20% of the invoice, minus their agreed fees.
The benefits of invoice factoring for UK businesses
For many growing companies, the primary advantage of factoring is the immediate boost to liquidity. However, there are several other reasons why a business might choose this route over other forms of finance.
First, it can help with business growth. As your sales increase, the amount of funding available to you also grows. This is often more flexible than a fixed-term loan or an overdraft, which may have rigid limits. Because the funding is tied directly to your sales volume, the facility scales naturally with your success.
Second, invoice factoring can save you time and money on administration. Because the factor handles the credit control, your team is free to focus on sales and operations rather than chasing late payments. For a small business without a dedicated accounts department, this “outsourced” credit control can be a significant benefit.
Finally, it may be easier to access than traditional bank finance. Factoring companies are often more concerned with the creditworthiness of your customers (the people paying the invoices) than your own business’s credit history. This can make it a viable option for newer businesses or those that do not have significant physical assets to use as security.
Understanding the costs and fees
While the benefits are clear, invoice factoring is not free. It is essential to understand the fee structure to ensure it remains a cost-effective choice for your margins. Typically, you will encounter two main types of charges.
The Service Fee: This is an administrative charge for managing your sales ledger and handling the collection process. It is usually calculated as a percentage of your annual turnover, typically ranging from 0.5% to 3%.
The Discount Rate: This is essentially the interest charged on the money advanced to you. It is often linked to the Bank of England base rate plus a specific margin. This is charged for the period the invoice remains unpaid.
There may also be additional costs such as setup fees, credit check fees, or exit fees if you decide to leave the contract early. It is always wise to read the terms and conditions carefully to identify any hidden costs that could impact your bottom line.
The potential risks and drawbacks
No financial product is without risk. When considering invoice factoring, you should be aware of how it might affect your business and customer relationships. One of the primary concerns for many business owners is customer perception. Because factoring is “disclosed,” your customers will know that you are using a finance provider. They will pay the factor directly and interact with the factor’s credit control team. While this is common in many industries, some businesses worry it may suggest they are struggling financially.
There is also the risk of “recourse.” In a standard recourse factoring agreement, if your customer fails to pay the invoice, you are responsible for paying the money back to the factor. This could lead to a sudden cash flow crisis if a major client goes bust. You can opt for “non-recourse” factoring, which includes bad debt protection, but this typically comes with higher fees.
Furthermore, factoring companies often have “concentration limits.” This means they may limit the amount of funding they provide for a single customer to spread their own risk. If you rely heavily on one large client, you might find that you cannot factor all of their invoices, leaving a gap in your expected cash flow.
Eligibility and applying for factoring
To qualify for invoice factoring in the UK, your business generally needs to be B2B (Business to Business) or B2G (Business to Government). It is not typically available for B2C businesses because the invoices must be for completed work or delivered goods with clear payment terms. Most factors will also require a minimum annual turnover, although some specialist providers cater specifically to startups.
Before you apply, it is helpful to ensure your sales ledger is organised and that your customers have a good track record of paying on time. The factor will likely conduct a review of your business processes and your customers’ credit standing. Get your free credit search here.

Factoring vs. Invoice Discounting
It is common to hear the terms “factoring” and “invoice discounting” used interchangeably, but they are different products. The main difference lies in who manages the collections and whether the arrangement is secret.
In invoice discounting, your business retains control over the sales ledger and continues to collect payments from customers. Your customers are usually unaware that you are using a finance facility. This is often preferred by larger, more established companies with their own credit control departments. Invoice factoring, conversely, involves the factor taking over the collections process and is almost always disclosed to the customer.
People also asked
What happens if a customer doesn’t pay a factored invoice?
If you have a recourse agreement, you must repay the advance to the factor or replace it with a new invoice. If you have non-recourse factoring, the factor typically absorbs the loss, provided the non-payment isn’t due to a dispute over your work.
Is invoice factoring expensive compared to a bank loan?
Generally, factoring can be more expensive than a traditional secured loan because it includes service fees for credit control. However, it may provide more total capital and offers flexibility that fixed loans cannot match.
Can I stop using invoice factoring at any time?
Most factoring contracts have a minimum term, often 12 to 24 months, and require a notice period to terminate. Always check your contract for “notice to terminate” clauses to avoid unexpected fees when switching providers.
Do factoring companies contact my customers directly?
Yes, in a standard factoring arrangement, the company will contact your customers to verify invoices and chase late payments. They usually act professionally to maintain your business relationship, but they will be identified as the finance provider.
Is my business too small for invoice factoring?
Not necessarily, as many modern UK factors specifically support small businesses and startups. As long as you sell to other businesses on credit terms, there is likely a provider that can help, though turnover requirements vary.
Final considerations for your business
Invoice factoring is a powerful tool for managing working capital, but it requires a strategic approach. It is most effective for businesses with healthy profit margins that can absorb the cost of fees in exchange for the speed and convenience of immediate cash. It is also highly beneficial for companies that lack the internal resources to manage a busy sales ledger.
However, you should always weigh the costs against the potential growth. If the fees are higher than the benefit you gain from having the cash early, it may not be the right choice. Always compare multiple providers and consider seeking professional advice to ensure you choose a facility that supports your long-term goals without placing undue strain on your customer relationships or your bottom line.
