How does invoice factoring work?

26th March 2026

By Simon Carr

TL;DR: Invoice factoring is a financial process where a business sells its unpaid invoices to a third party to receive an immediate cash advance. This helps bridge the gap between completed work and customer payment, though it carries costs and means the factor will manage your customer collections.

How does invoice factoring work?

For many UK business owners, waiting 30, 60, or even 90 days for customers to settle their invoices can create significant cash flow challenges. This delay can make it difficult to pay staff, purchase raw materials, or invest in growth. This is where invoice finance, specifically invoice factoring, may provide a solution. But how does invoice factoring work in practice, and is it the right choice for your organisation?

Invoice factoring is a type of asset-based finance. Instead of waiting for a customer to pay, you “sell” the value of your outstanding invoices to a specialist provider, known as a factor. The factor provides you with most of the invoice value upfront, typically within 24 to 48 hours. They then take over the responsibility of collecting the payment from your customer. Once the customer pays the factor, the remaining balance is returned to you, minus a pre-agreed fee.

The step-by-step process of invoice factoring

Understanding the mechanics of a factoring agreement can help you decide if it aligns with your business operations. While every provider has slightly different terms, the general process typically follows these six steps:

  • Step 1: Invoicing your customer. You provide goods or services to another business as usual and issue an invoice. You then send a copy of this invoice to your factoring provider.
  • Step 2: Verification. The factoring company may perform a quick check to ensure the invoice is valid and that the goods or services have been delivered.
  • Step 3: The initial advance. The factor pays you a percentage of the invoice value, usually between 80% and 90%. This cash is generally available within one business day, providing an immediate boost to your working capital.
  • Step 4: Credit control and collections. This is a key feature of factoring. The factor’s own credit control team will contact your customer to manage the collection of the debt. They handle the administrative side of chasing payments, which can save your business time and resources.
  • Step 5: Customer payment. Your customer pays the invoice directly to the factoring company. Because the factor manages the collections, your customers will typically be aware that you are using a factoring service.
  • Step 6: Settlement of the balance. Once the factor receives the full payment from your customer, they pay you the remaining 10% to 20% of the invoice value. At this stage, they deduct their service fees and interest charges.

How much does invoice factoring cost?

The cost of invoice factoring varies depending on your turnover, the sector you work in, and the creditworthiness of your customers. Generally, you can expect to encounter two primary types of charges:

The Service Fee: This is often called an administration fee. It covers the cost of the factor managing your sales ledger and chasing payments. It is typically calculated as a percentage of your annual turnover, usually ranging from 0.5% to 3.5%.

The Discount Rate: This is essentially the interest you pay on the money the factor has advanced to you. It is often charged daily and is usually linked to the Base Rate. Because you only pay interest on the money you have actually drawn down, it can be a flexible way to manage costs.

Factoring vs Invoice Discounting: What is the difference?

When researching how does invoice factoring work, you may also come across “invoice discounting.” While they are both forms of invoice finance, there is one major difference: who collects the money. In a factoring arrangement, the factor manages your credit control and communicates with your customers. In invoice discounting, you retain control of your sales ledger and chase your own payments. This means invoice discounting is usually “confidential,” as your customers do not know you are using a finance facility.

Factoring is often preferred by smaller businesses or those that do not have a dedicated accounts department. It provides both the finance and the administrative support to ensure debts are paid. Larger businesses with established credit control teams may prefer invoice discounting to maintain a direct relationship with their clients.

Recourse vs Non-recourse factoring

It is vital to understand the difference between recourse and non-recourse agreements, as this determines who bears the risk if a customer fails to pay. In a recourse factoring agreement, your business remains liable for the debt. If your customer becomes insolvent or simply refuses to pay, you must buy back the invoice from the factor or replace it with a new one. This is the most common and affordable type of factoring.

In non-recourse factoring, the factor takes on the credit risk. If the customer does not pay, the factor absorbs the loss. Because the factor is taking on more risk, the fees for non-recourse agreements are generally higher. Many businesses find this extra cost worthwhile for the peace of mind that comes with “bad debt protection.”

The benefits of invoice factoring

For many UK SMEs, the primary benefit is the elimination of the “waiting game.” Instead of having capital tied up in unpaid bills, you have immediate access to funds to reinvest. This can be particularly useful for seasonal businesses or those experiencing rapid growth that requires constant cash flow for stock or recruitment.

Additionally, because the factor handles the credit control, business owners can focus on their core operations rather than spending hours on the phone chasing late payments. It can also be easier to secure than a traditional bank loan because the finance is secured against the value of your invoices rather than your property or other fixed assets.

The potential risks and considerations

Despite the benefits, invoice factoring is not a “risk-free” solution. One major consideration is the impact on customer relationships. Because the factor communicates directly with your clients, you lose some control over how your brand is perceived during the collections process. If a factor is too aggressive in chasing a payment, it could potentially harm a long-standing client relationship.

There is also the cost to consider. Over the long term, factoring can be more expensive than other forms of finance like a standard bank loan or an overdraft. Furthermore, most factoring agreements involve a whole-ledger requirement, meaning you must factor all your invoices, not just the ones you want to. Ending a factoring contract early may also result in termination fees, so it is important to read the terms of the agreement carefully.

Is invoice factoring expensive?

The cost typically ranges from 0.5% to 5% of your total invoice value, making it more expensive than some traditional loans but often more accessible for fast-growing firms.

Many providers offer factoring to startups and new businesses, provided they are trading B2B and have creditworthy customers who have been invoiced for completed work.

Does factoring affect my credit score?

Using factoring doesn’t typically damage your credit score; in fact, the improved cash flow may help you pay your own suppliers on time, which can strengthen your credit profile.

Summary

Invoice factoring is a powerful tool for businesses looking to unlock the value held in their sales ledger. By providing immediate cash and taking over the burden of credit control, it allows business owners to focus on growth rather than administrative debt collection. However, the costs and the loss of direct contact with customers mean it is a decision that requires careful thought. By weighing the benefits of instant liquidity against the service fees and contract terms, you can determine if factoring is the most suitable path for your business’s financial future.
