Invoice finance and factoring: turn unpaid invoices into cash

Invoice factoring is one of the most practical and widely used forms of invoice finance in the UK. It allows businesses to unlock the value sitting in their unpaid sales invoices rather than waiting 30, 60 or even 90 days for customers to settle their accounts.

For many businesses, the gap between raising an invoice and receiving payment is not just inconvenient. It creates real pressure on wages, supplier payments, stock purchases and day-to-day operations. Invoice factoring closes that gap.

What Is Invoice Factoring?

Invoice factoring is a financing arrangement where a business sells its outstanding invoices to a specialist provider, known as a factor, in exchange for an immediate cash advance.

Rather than waiting for a customer to pay, the business receives a percentage of the invoice value upfront, typically between 70% and 90%, with the remainder released once the customer settles the invoice, minus the factor’s fees.

This makes factoring fundamentally different from a traditional loan. The funding is not based on a fixed borrowing limit tied to assets or credit history. It is linked directly to the invoices raised and the performance of the debtor book. As turnover grows and more invoices are raised, the available funding grows with it.

The factor then takes responsibility for managing the sales ledger and collecting payment from the business’s customers. This is a key distinction between factoring and other receivables finance products.

How Invoice Factoring Works: Step by Step

Understanding the mechanics of factoring helps businesses assess whether it is genuinely the right tool for their situation.

1. The business raises an invoice with a customer as normal.
2. The invoice is submitted to the factoring provider.
3. The factor releases an agreed percentage of the invoice value, typically within 24 to 48 hours.
4. The factor manages the collection process and chases the customer for payment.
5. When the customer pays, the factor releases the remaining balance, minus their fees.

This cycle repeats continuously as new invoices are raised, meaning the facility scales naturally alongside the business.

Who Uses Invoice Factoring?

Invoice factoring is commonly used by businesses that invoice other businesses on credit terms and face cash flow pressure because customers pay later than the business needs to spend.

It tends to work particularly well for:

• Growing businesses that are winning new contracts but struggling to fund them
• Labour-intensive firms where wages must be paid weekly or monthly regardless of when customers settle
• Seasonal businesses that experience sharp peaks and troughs in cash availability
• Companies where a small number of large customers mean delayed payment has a significant impact
• Businesses that are expanding into new markets and need working capital to fund the transition

The common thread is that the business is generating genuine sales and raising real invoices but is experiencing a timing mismatch between spending and income.

What Does Invoice Factoring Cost?

Factoring fees vary by provider, sector, turnover and debtor quality. Understanding the typical cost structure helps businesses budget accurately and compare facilities properly.

The total cost of factoring depends on how quickly customers pay and how much of the facility is drawn at any one time. A business with fast-paying debtors will typically incur lower discount charges than one with slow payers.

Realistic UK Example: How the Numbers Work

Illustrative figures only. Actual rates, fees and loan amounts depend on the lender and your circumstances.

Consider a business with a single invoice raised for £50,000 with 60-day payment terms.

The factoring provider advances 85% of the invoice value upfront, releasing £42,500 to the business within 24 hours.

The service fee is 1.5% of the invoice value, which equals £750.

The discount charge is calculated on the £42,500 advanced at an annualised rate of 6%. For 60 days, that works out to approximately £420.

When the customer pays the £50,000 invoice in full at day 60, the factor releases the remaining £7,500 balance, minus the £750 service fee and £420 discount charge. The business receives approximately £6,330 as the final settlement.

Total cost of funding for this invoice: approximately £1,170. Total cash received: approximately £48,830 against an invoice of £50,000.

For most businesses, access to £42,500 within 24 hours instead of waiting 60 days is worth considerably more than the £1,170 cost, particularly when that cash is needed to pay wages, buy stock or fund the next phase of a contract.

Invoice Factoring vs Invoice Discounting

These two products are closely related but serve different needs. Understanding the distinction matters when choosing between them.

Factoring involves more provider involvement around the debtor book. Invoice discounting is often more confidential and leaves customer-facing control entirely with the business.

Businesses comparing different receivables finance solutions can explore Invoice Discounting to understand how it differs from factoring in terms of control and customer visibility.

Neither product is inherently better. The right choice depends on the business’s size, the quality of its credit control processes and whether it values outsourcing that function or retaining it.

The Benefits of Invoice Factoring

The practical advantages of a well-structured factoring facility extend beyond simple cash flow improvement.

Improved working capital. Businesses can unlock funds tied up in unpaid invoices earlier, reducing pressure around wages, suppliers and operational costs.

Outsourced credit control. The factor manages the collections process, which can save significant time and resource for smaller businesses without a dedicated finance team.

Scalable funding. Unlike a fixed overdraft or loan, the facility grows naturally as turnover increases. A business generating more invoices has access to more funding automatically.

Faster response to opportunity. Businesses can take on new contracts and fulfil orders without waiting for long customer payment cycles to catch up.

Reduced bad debt exposure. Some providers offer Bad Debt Protection as part of the factoring arrangement, which reduces exposure to unpaid invoices and strengthens overall cash flow resilience. This can be particularly valuable where a small number of large customers represent a significant concentration of risk.

What Lenders Assess When Reviewing a Factoring Facility

Factoring providers carry out their own assessment before offering a facility. Understanding what they look at helps businesses prepare properly and reduces the risk of delays.

Debtor quality. The credit standing of the customers being invoiced is central to any factoring assessment. Providers want to see that the businesses being invoiced are creditworthy and likely to pay.

Invoice validity. Invoices must represent genuine, completed transactions. Providers will not advance against invoices for goods or services not yet delivered.

Concentration risk. If a single customer accounts for the majority of a business’s turnover, that concentrates risk significantly. Providers prefer a spread of debtors.

Business stability. Whilst factoring is available to early-stage businesses, providers assess trading history, management experience and sector.

Existing charges. If the business has an existing lender with a debenture or charge over assets, this can affect how a factoring arrangement is structured.

Common Mistakes to Avoid

Businesses approaching factoring for the first time often make similar errors that can delay approvals or result in facilities that do not fit their needs.

• Assuming the cheapest headline rate represents the best overall facility
• Submitting invoices that have not yet been fulfilled, which invalidates the advance
• Not disclosing existing finance arrangements or charges
• Choosing a factoring provider without understanding the collections approach used with their customers
• Underestimating the importance of debtor quality to the available facility size

A specialist broker can help identify these risks before a formal application is made, which often results in faster approvals and better-structured facilities.

What is invoice finance?

Invoice finance is the umbrella term for funding raised against the money your customers owe you. UK Finance, the trade body for the sector, describes the core asset as the debtor book (your unpaid invoices), which is why it is also called receivables finance. You are likely to be offered one of three forms:

• Factoring. Funding against your invoices combined with credit control: the provider chases and collects payment. It is typically used by start-ups and smaller businesses.
• Invoice discounting. Funding against your invoices while you keep collecting from customers yourself. It can be confidential or disclosed, and tends to suit businesses with their own credit control.
• Selective or spot facilities. Funding against a single invoice or a chosen customer, not the whole sales ledger. It can cover a one-off gap, though the cost for each invoice is often higher.

What an invoice finance broker does

Providers differ in the sectors they fund, the size of facility they offer and how their contracts are written. As a broker we:

• compare facilities and providers against the way your business invoices and gets paid;
• explain the fee structure, so you can compare the service fee, discount charge and any extras on the same basis;
• check the contract terms that catch businesses out, such as minimum periods, notice and concentration limits.

A broker is paid by a fee you pay, a commission from the provider, or both. Ask which applies, and how much, in writing before you commit.

Is invoice finance regulated?

Generally, no. UK Finance stated in January 2025 that invoice finance and asset-based lending are business finance that is not currently subject to statutory conduct regulation in the UK. Its complaints guidance adds that the Financial Ombudsman Service will not currently consider a complaint that is mainly about these services.

What exists instead is the Standards Framework, which covers UK Finance's invoice finance and asset-based lending members. It consists of a code, a Professional Standards Council and an independent complaints process. That process is free to use, is open to clients and their guarantors, and can award up to £50,000 for issues arising on or after 1 January 2021. You must complain to the provider first, and it has up to 12 weeks to resolve the matter.

Membership is voluntary. UK Finance estimates that members provide at least 90% of UK invoice finance and asset-based lending by volume, but clients of non-members, including online invoice-trading platforms, are not covered. So ask every provider: are you a UK Finance member covered by the Standards Framework?

Contract terms to read before you sign

• Minimum term and notice. How long you are tied in, and how much notice you must give to leave.
• Minimum fees. Whether a fee applies even when you use the facility lightly.
• All-turnover or selective. Whether every invoice must go through the facility or you can choose.
• Recourse period. How long an invoice can stay unpaid before the provider takes back what it advanced.
• Concentration limits. The cap on how much of your funding can rest on one customer.
• Personal guarantees. Whether directors must give a guarantee or indemnity. Read personal guarantees explained first.
• Termination fees. What it costs to end the agreement early.

If a customer never pays

Invoice finance brings cash forward. It does not, by itself, protect you from a customer that never pays: under a recourse facility that loss stays with you. Bad debt protection, which some providers build into the facility, limits that risk.
