What types of invoices can be factored?

Invoice factoring is a vital financial tool for UK businesses seeking to unlock cash tied up in unpaid sales invoices. It involves selling your outstanding invoices (accounts receivable) to a factoring company (the factor) at a discount, providing immediate liquidity. Determining eligibility depends heavily on the nature of the invoice, the terms of trade, and the creditworthiness of your customer (the debtor). Generally, factoring applies to verified, undisputed debts owed by business customers.

Understanding What Types of Invoices Can Be Factored in the UK

For a business to successfully utilise invoice factoring, the invoice itself must meet strict criteria set by the factoring company. These criteria exist to manage the factor’s risk, as they are purchasing the right to collect that debt. Factoring facilities are generally focused on high-quality, verifiable accounts receivable.

Understanding which invoices are eligible is crucial for managing your cash flow expectations and structuring your agreement with the factoring provider.

Core Eligibility Criteria for Invoices

Factoring companies look for several key attributes when assessing whether an invoice qualifies for immediate advance funding. If an invoice fails to meet these core criteria, it is unlikely to be accepted, regardless of the industry you operate in.

1. Business-to-Business (B2B) Transactions Only

The primary requirement for nearly all UK factoring facilities is that the invoice must be generated from a transaction between two businesses (B2B). Factoring companies typically do not purchase debts owed by individual consumers (B2C debt). This is because consumer debt is usually subject to different regulatory requirements, is harder to collect, and presents higher default risk than corporate debt.

2. Completed, Verified Sales

The invoice must relate to goods delivered or services fully rendered. Factoring companies are reluctant to purchase invoices related to progress payments, deposits, or future contracts where the service or delivery is not yet complete. The debt must be concrete, undisputed, and fully earned. If there is a possibility the client might refuse payment due to incomplete work, the factor will not take on the risk.

3. Undisputed Debt

The debtor must acknowledge the invoice is legitimate and owed. If the customer disputes the quality of the goods, the scope of the service, or the amount invoiced, the invoice is immediately ineligible for factoring. Factoring companies usually require the seller (your business) to take back any factored invoice that becomes disputed.

4. Clear and Manageable Payment Terms

Factoring is designed to bridge the gap between issuing an invoice and receiving payment. Therefore, the invoice must have defined payment terms that fall within the factor’s acceptable limits. Typically, invoices with terms of 30, 60, or 90 days are acceptable. Invoices that are already severely overdue (often over 90 days past the due date) or those with excessively long terms (e.g., 120 days plus) are often excluded.

5. Creditworthiness of the Debtor

While the factoring decision is primarily based on the quality of the debt, the factor must also assess the financial health of your customer (the debtor). If the customer is deemed financially unstable or has a poor credit history, the factor may decline to purchase invoices relating to that specific debtor, even if your business is strong.

When assessing a factoring application, the factor also conducts due diligence on your own company’s financial stability and operational history.

Common Types of Factored Invoices Across UK Industries

Provided the core criteria are met, many different types of invoices generated by businesses across various sectors can be factored. The system is particularly useful in industries where payment delays are common.

• Manufacturing and Distribution: Invoices for finished goods sold and shipped to trade customers, often involving significant stock investment and long payment terms.
• Wholesale Trade: Factoring invoices for bulk orders delivered to retailers or other distributors.
• Recruitment Agencies: This is a very common sector for factoring. Invoices for temporary staff placements (often billed weekly or monthly) are factored, allowing agencies to pay staff wages immediately while waiting for corporate clients to settle their bills.
• Logistics and Transport: Invoices for haulage services, shipping, and delivery fees, especially those dealing with other corporate clients.
• Service Industries (B2B): Invoices for consulting, IT support, professional services, or business cleaning contracts.
• Construction Subcontractors: Invoices for completed phases of work or verified contractual amounts, although factors are cautious about “pay when paid” clauses often found in the main contract documentation.

The key factor (no pun intended) is the verifiability and transferability of the debt. If the debt is clearly defined and owed by one company to another, it is generally considered good collateral for factoring.

Invoices and Transactions That Are Typically Excluded

While factoring is highly versatile, certain types of financial obligations or transaction structures are almost always excluded by factoring providers due to complexity, high risk, or legal limitations.

1. Related Party Invoices

Invoices issued to companies that are owned or controlled by the same individuals or parent group (inter-company debt) are almost never factored. This prevents businesses from artificially generating debts to access funding.

2. Pro Forma Invoices and Estimates

These documents are requests for payment or preliminary figures, not legal statements of debt owed for completed work. Only final, legitimate sales invoices are considered.

3. Conditional or Contingent Invoices

If the payment of the invoice depends on a future event or condition being met (other than the passage of time), it is deemed contingent and unsuitable for factoring. For example, an invoice where payment is only due if the final project passes a specific external audit.

4. Foreign Debt (Cross-Border Factoring Complexity)

While international factoring does exist, many UK providers focus solely on domestic invoices due to the complexities of international law, different payment conventions, exchange rate risk, and collection difficulties. If you deal heavily with overseas clients, you may need a specialist export factoring facility.

It is also important to note that factoring only applies to accounts receivable (money owed to you). It cannot be used to settle your own accounts payable (money you owe others), nor is it a substitute for secured lending or overdraft facilities.

Businesses seeking funding should carefully review their eligibility criteria, as detailed by organisations like the Financial Conduct Authority (FCA), which oversees many business lending practices. You can find general guidance on business finance options through the UK government-backed consumer advice services to better understand your choices, such as MoneyHelper Business Finance information.

Understanding Recourse vs. Non-Recourse Factoring

The risks associated with the factored invoice also influence eligibility and pricing. Factoring arrangements fall into two main types:

• Recourse Factoring: This is the most common and often cheaper option. If the debtor fails to pay the invoice (e.g., due to bankruptcy or insolvency), your business remains liable. You would be required to buy the invoice back from the factor.
• Non-Recourse Factoring: The factor takes on the credit risk of the debtor defaulting. If the debtor becomes insolvent, the factor bears the loss. This option is more expensive and often has stricter eligibility criteria for the debtor’s credit rating.

In both cases, if the customer simply refuses to pay due to a genuine dispute (not insolvency), the factor will usually revert the invoice back to your business, as the factor only assumes the risk of credit default, not commercial disputes.

People also asked

Is factoring suitable for all sizes of invoice?

Yes, factoring can be applied to invoices of almost any size, from a few hundred pounds up to millions, provided the invoices meet the core eligibility criteria. Many providers have minimum turnover requirements for the business overall, rather than strict minimums for individual invoices.

Can invoices that are already overdue be factored?

It depends on how far overdue they are. Most factoring companies prefer ‘fresh’ invoices (less than 30 days old). If an invoice is significantly overdue (e.g., 90 days past the due date), a factor is unlikely to purchase it, as the risk of non-payment increases sharply once an invoice is aged.

Are invoices with retention clauses eligible for factoring?

Invoices containing retention clauses (where a portion of the payment is held back pending project sign-off, common in construction) are problematic. Factoring companies typically only purchase the undisputed portion of the invoice, excluding the amount held in retention, or may decline them entirely due to the contingency involved.

Can I factor invoices from international customers?

Yes, but you require a specialist export factoring facility. These facilities are designed to handle foreign currency exchange, cross-border legal compliance, and international credit checking, making the service more complex and potentially more expensive than domestic factoring.

Invoice factoring is a highly effective way for businesses to manage working capital when they have long payment cycles, but its success relies entirely on the quality and eligibility of the underlying sales invoices. By focusing on generating undisputed B2B debt with creditworthy clients and clear terms, businesses maximise their access to this crucial financing option.
