What is the process of invoice factoring?

TL;DR: Invoice factoring is a financial process where a business sells its unpaid invoices to a third party to improve cash flow. While it provides quick access to funds, it involves fees and the factoring company typically manages your sales ledger and collections directly.
What is the process of invoice factoring?
Managing cash flow is one of the most significant challenges for growing businesses 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, purchase raw materials, or invest in new opportunities. Invoice factoring is a type of invoice finance designed to bridge this gap by providing immediate access to the value of your outstanding invoices.
The process of invoice factoring involves more than just a simple loan; it is a comprehensive financial service that includes funding and credit control. Understanding each step of the journey is essential for any business owner considering this facility to ensure it aligns with their operational needs and customer relationships.
The initial setup and agreement
The process begins before any money changes hands. First, a business must apply to a factoring provider. During this stage, the provider will conduct “due diligence” to assess the health of your business and the quality of your sales ledger. Unlike a traditional bank loan, which focuses primarily on your own creditworthiness, a factoring company is often more interested in the creditworthiness of your customers (the debtors).
Before an agreement is finalised, the provider will likely perform credit checks on your business and your key clients. Get your free credit search here. It’s free for 30 days and costs £14.99 per month thereafter if you don’t cancel it. You can cancel at anytime. (Ad)
Once the provider is satisfied, they will offer a facility. This agreement will outline the advance rate (the percentage of the invoice value you receive upfront), the service fees, and the discount rate (the interest charged on the advanced funds). Typically, advance rates range from 70% to 90% depending on your industry and the perceived risk.
Step 1: Providing goods or services
The cycle of invoice factoring starts with your standard business operations. You fulfill an order for a customer or complete a contracted service. It is vital that the work is fully completed and that there are no disputes regarding the quality or delivery, as factoring companies generally only fund “clean” invoices where the debt is undisputed.
Step 2: Issuing the invoice
Once the work is done, you issue an invoice to your customer as usual. However, in an invoice factoring arrangement, the invoice will typically include a “notice of assignment.” This is a clear statement informing your customer that the debt has been assigned to the factoring company and that payment must be made directly to them. You will then send a copy of this invoice to the factoring provider, often through an online portal or integrated accounting software.
Step 3: Receiving the advance
After you submit the invoice, the factoring company will verify it. Once verified, they will transfer the agreed “advance” into your business bank account. This typically happens within 24 to 48 hours. For many businesses, this is the most critical part of the process of invoice factoring, as it provides the liquidity needed to continue trading without waiting for the customer’s credit term to expire.
The advance is not the full value of the invoice. The factoring company retains a small percentage (the reserve) to cover potential issues such as credit notes, discounts, or disputes. This reserve is eventually returned to you, minus fees, once the customer pays.
Step 4: The credit control process
One of the defining features of invoice factoring—which distinguishes it from invoice discounting—is that the factoring company takes over your credit control. This means their professional collections team will manage your sales ledger. They will send statements, make phone calls, and follow up on overdue payments.
While this can save your business time and reduce administrative overheads, it is a “disclosed” facility. Your customers will be fully aware that you are using a factoring service. For some businesses, this is seen as a benefit as it adds a layer of professionalism to the collections process. For others, there may be concerns about how this affects long-term customer relationships. It is important to choose a provider that communicates with your customers in a way that matches your brand’s tone.
Step 5: Customer payment and the rebate
When the customer’s payment becomes due, they pay the factoring company directly. Once the funds have cleared, the process of invoice factoring enters its final stage. The provider will calculate the remaining balance of the invoice (the portion they didn’t advance initially).
From this remaining balance, they will deduct their fees. These usually include a service fee (for managing the ledger) and a discount fee (the cost of borrowing the money). The remaining amount, often called the “rebate,” is then paid into your business account. This completes the cycle for that specific invoice.
Understanding the costs and risks
While invoice factoring is a powerful tool for growth, it is not without risks and costs. Businesses should be aware that it can be more expensive than traditional bank overdrafts or loans because you are paying for both the capital and the outsourced credit control service. Fees may vary based on your turnover and the number of customers you have.
There is also the risk of “recourse.” Most factoring agreements in the UK are “recourse” agreements. This means that if your customer fails to pay the invoice after a certain period (typically 90 days), the factoring company will ask you to buy back the debt or will deduct the advanced amount from your future funding. You can opt for “non-recourse” factoring, which includes credit insurance to protect against bad debts, though this typically comes with higher fees.
You can find more information about the different types of business finance and how they are structured on the official UK Government website.
Is your business eligible?
Typically, invoice factoring is available to businesses that sell to other businesses (B2B) on credit terms. It is less common for businesses that sell directly to the public (B2C). Providers generally look for a minimum annual turnover, though some specialist providers cater specifically to startups and small enterprises. Your business should also have a history of generating reliable invoices with minimal disputes.
People also asked
How much does invoice factoring cost?
The cost usually consists of a service fee (0.5% to 3% of turnover) and a discount rate (1% to 5% above the base rate). Total costs depend on your business size and the creditworthiness of your clients.
What is the difference between factoring and invoice discounting?
In factoring, the provider manages your credit control and the facility is disclosed to customers. With invoice discounting, you maintain your own credit control, and the arrangement is usually kept confidential.
Can I use factoring if I have a new business?
Yes, many factoring providers offer facilities to startups because the security is based on the value of the invoices and the credit strength of your customers rather than your company’s long-term trading history.
Will my customers know I am using a factoring company?
Yes, in a standard factoring arrangement, customers are notified through the “notice of assignment” on invoices and will interact with the factor’s credit control team for payments.
What happens if a customer refuses to pay?
In a recourse agreement, you are ultimately responsible for the debt and must repay the advance to the factor. In a non-recourse agreement, the factor may absorb the loss if the customer becomes insolvent, provided terms are met.
Summary of the factoring journey
The process of invoice factoring is a cyclical journey that repeats every time you raise an invoice. It begins with the delivery of work, followed by an immediate cash injection, and ends with the professional collection of the debt. By converting your accounts receivable into ready cash, you can potentially maintain a smoother operation and take on larger contracts that you might otherwise have to turn down due to lack of working capital.
However, it is vital to remember that you are entering into a long-term financial partnership. You should carefully review the terms of any agreement, noting the notice periods and any minimum usage requirements. While it may provide the fuel for growth, ensuring the costs are manageable and the impact on customer relations is understood remains the responsibility of the business owner. Always compare different providers to ensure the service level and fee structure match your specific business goals.
