Invoice factoring is a powerful financial tool designed to unlock immediate working capital tied up in outstanding sales invoices. It involves selling your business’s accounts receivable (invoices) to a third party, known as the ‘factor’, at a discount. This immediate injection of cash helps businesses manage payroll, purchase inventory, and bridge cash flow gaps without waiting 30, 60, or 90 days for clients to pay.
What is the Process of Invoice Factoring?
For UK businesses struggling with delayed customer payments, understanding what is the process of invoice factoring is key to utilising this financing method effectively. The process is generally straightforward and follows a sequence of five crucial stages, from initial setup to the final settlement of funds.
Understanding Invoice Factoring: The Mechanism
Invoice factoring is distinct from traditional lending, as it relies on the quality of your customers (debtors) rather than solely on your business’s credit history or assets. It is essentially the outright sale of an asset (the invoice). The factor takes ownership of the debt and assumes the responsibility for managing collections.
Factoring is often employed by growing small and medium-sized enterprises (SMEs) that have strong sales but limited liquid cash flow due to extended payment terms offered to customers. This financial solution focuses on liquidity and acceleration of cash conversion cycles.
The Step-by-Step Process of Invoice Factoring
The factoring process involves the business (the seller), the factoring company (the factor), and the customer who owes the money (the debtor).
Step 1: Agreement and Setup
Before any invoices can be submitted, the business must establish a formal relationship with the factor. This initial phase involves comprehensive due diligence and setting the contractual terms.
- Application and Assessment: The business applies to the factor, providing details about its sales volume, average invoice size, debtor profile (who they sell to), and standard payment terms.
- Due Diligence: The factor assesses the creditworthiness of both your business and, more importantly, your debtors. They need assurance that the invoices they purchase are likely to be paid.
- Contract Negotiation: Terms such as the advance rate (e.g., 85%), the discount fee (the interest rate charged while the debt is outstanding), and the service fee (for collections and administration) are agreed upon.
- Notification: In standard factoring arrangements (known as ‘notified factoring’), the factor requires the business to formally inform the debtors that future payments should be made directly to the factor. This step is critical as it formally assigns the debt.
During the due diligence stage, factors may run credit checks on the business principals.

Step 2: Invoice Submission
Once the legal agreement is in place, the process becomes transactional.
- When the business raises an invoice to a customer for goods or services rendered, instead of waiting for payment, they submit a copy of that invoice (or a batch of invoices) to the factor.
- The factor verifies the validity of the invoice, confirming that the goods or services have been delivered and the debt is legitimate and uncontested.
Step 3: Advance Payment (The Uplift)
This is the stage where the business receives the immediate cash injection.
- The factor advances an agreed-upon percentage of the total invoice value to the business, typically ranging from 80% to 90%. This advance is usually deposited into the business’s bank account within 24 to 48 hours of invoice submission.
- The remaining percentage (the ‘retention’ or ‘reserve’) is held back by the factor.
For example, if a business submits a £10,000 invoice with an 85% advance rate, the business immediately receives £8,500.
Step 4: Collection Management
A key distinguishing feature of factoring is that the factor takes on the responsibility of collections.
- The factor contacts the debtor and manages the process of ensuring payment is made by the due date.
- This involves sending payment reminders, statements, and handling customer queries related to payment. The factor essentially acts as the business’s credit control department, often reducing the administrative burden on the selling business.
- The debtor pays the full invoice amount directly into a bank account controlled by the factor (often a trust account).
The factor must adhere to established UK debt collection guidelines and maintain professionalism, as they are now representing the business in the eyes of its customers. UK businesses should ensure their factor operates compliantly. For guidance on managing business finances and potential disputes, resources like MoneyHelper can be useful.
Step 5: Final Payment and Fees Settlement
Once the debtor pays the full invoice amount, the factoring process concludes with the settlement of the reserve balance.
- The factor subtracts their combined fees from the reserve amount. These fees include the discount fee (calculated based on how long it took the debtor to pay) and the service fee (for administration and collection efforts).
- The remaining balance of the reserve is then transferred back to the business.
Continuing the example: If the £10,000 invoice is paid, and the total factoring fees amount to £400, the factor releases the reserve (£1,500) minus the fees (£400), resulting in a final payment of £1,100 to the business.
Recourse vs. Non-Recourse Factoring
An essential consideration in the factoring process is how risk is handled, which defines whether the arrangement is ‘recourse’ or ‘non-recourse’.
Recourse Factoring
In recourse factoring, the most common and typically cheaper option, the selling business retains the credit risk. If the debtor fails to pay the invoice (due to insolvency, for example), the factor has ‘recourse’ to the selling business. This means the business is obligated to repay the advance plus any accrued fees to the factor. This places the ultimate burden of bad debt back onto the original seller.
Non-Recourse Factoring
Non-recourse factoring is generally more expensive but provides greater protection. Under this arrangement, the factor assumes the credit risk of the debtor. If the debtor genuinely cannot pay due to specific circumstances (usually insolvency or bankruptcy), the factor absorbs the loss. Note that non-recourse agreements typically only cover insolvency risk, not commercial disputes (e.g., if the debtor refuses to pay because they claim the service was faulty).
Costs and Fees Associated with Factoring
The cost structure of factoring is crucial when assessing its viability. Costs typically fall into two categories:
1. The Discount Fee (Interest Charge)
This is the primary financial charge, similar to an interest rate, applied to the amount advanced. It is calculated based on the outstanding amount and the duration the invoice remains unpaid. Factors typically quote this as a percentage per annum or per month above a base rate, although the final fee is often paid as a percentage of the invoice value.
The longer the debtor takes to pay, the higher the discount fee accrues, as the factor’s capital is tied up for a longer period.
2. The Service Fee (Administration Charge)
This covers the factor’s administrative costs for managing the sales ledger, credit checking debtors, and executing the collection process. This fee is usually a fixed percentage of the gross value of the invoice, regardless of how long the debt takes to settle.
- Factors might charge higher service fees for businesses with a high volume of small invoices or clients with historically poor payment behaviour.
Businesses must carefully weigh the total cost of factoring against the benefit of immediate liquidity.
Benefits and Risks of Using Invoice Factoring
While factoring offers significant advantages, it also carries potential drawbacks that must be considered by any UK business.
Key Benefits
- Improved Cash Flow: Immediate access to funds significantly boosts working capital, allowing businesses to meet short-term obligations and seize growth opportunities.
- Outsourced Credit Control: The factor manages collections, reducing the need for in-house credit control staff and associated administrative costs.
- Scalability: As sales grow, the available funding grows automatically, as the facility is tied directly to the volume of invoices raised.
- Accessibility: Factoring often focuses on the quality of the debtors rather than the selling business’s historical profitability, making it accessible to startups and rapidly growing firms that may not qualify for traditional bank loans.
Potential Risks and Considerations
- Cost: Factoring can be more expensive than traditional bank overdrafts or loans, especially if customers take a long time to pay.
- Loss of Control: The business cedes control over the credit control function to the factor, which can impact customer relationships if the factor employs overly aggressive collection methods.
- Reputational Impact (Notification): In standard factoring, debtors know the debt has been sold, which some businesses feel diminishes their standing or suggests financial strain.
- Non-Recourse Limits: Even with non-recourse factoring, the business remains liable for commercial disputes, meaning they may still have to refund the factor if a customer refuses payment due to a dispute over goods or services.
For UK businesses operating in sectors where late payment is endemic, factoring can be a lifeline. However, it is vital to research the factor’s reputation and ensure their collection practices align with your commitment to customer service. The government provides useful guidance on how businesses can tackle late payments, which might complement a factoring arrangement.

Factoring vs. Invoice Discounting: A Key Distinction
It is important not to confuse factoring with invoice discounting, though both involve using invoices for finance.
- Invoice Factoring: The factor manages the sales ledger and handles collections. The debtor knows the debt has been sold (notified factoring).
- Invoice Discounting: The business receives an advance but retains responsibility for collections. The debtor is usually unaware that the invoice has been used for finance (confidential discounting). This option is typically only available to established businesses with robust internal credit control departments.
Factoring is generally preferred by businesses that wish to outsource their credit management entirely, while discounting is favoured by businesses prioritising confidentiality and maintaining direct control over customer communications.
People also asked
How long does the invoice factoring process take to set up?
The initial setup time for an invoice factoring facility typically takes between one and four weeks, depending on the complexity of the business, the number of debtors, and the speed of the factor’s due diligence process. Once set up, subsequent invoice submissions usually result in funds being advanced within 24 to 48 hours.
Is invoice factoring considered a loan?
No, invoice factoring is not technically a loan; it is the sale of a financial asset (the invoice). Loans create debt that must be repaid regardless of customer payment status, while factoring converts an asset into cash. Consequently, factoring may not appear on a balance sheet as a liability, although accounting standards require careful classification.
What percentage of an invoice can I typically expect to receive upfront?
Most factoring facilities offer an advance rate between 80% and 90% of the gross invoice value. The precise percentage depends on the factor’s assessment of the risk profile, which includes the creditworthiness of your debtors and the average payment period.
Do my customers know I am using invoice factoring?
In standard (notified) factoring, yes, your customers will be aware, as they are formally notified that the payment address has changed and they must pay the factor directly. Confidential factoring (invoice discounting), however, allows the business to retain control of collections, meaning the customer is usually unaware.
What happens if a customer refuses to pay the factored invoice?
If the customer refuses to pay due to a commercial dispute (e.g., damaged goods), the business is almost always responsible for resolving the dispute and may have to buy the invoice back from the factor. If the customer is unable to pay due to insolvency, the liability depends on whether you are using recourse or non-recourse factoring.
Can a factor limit which invoices I submit?
Yes, factors usually set specific eligibility criteria within the agreement. They may refuse to purchase invoices from debtors deemed too high-risk, those located in certain jurisdictions, or invoices that exceed specific credit limits they have set for individual customers.
In summary, invoice factoring provides a reliable pathway to liquidity by monetising accounts receivable instantly. Businesses considering this option should focus on establishing a clear understanding of the full fee structure, the advance rate, and whether a recourse or non-recourse agreement best mitigates their inherent risk.
