What happens if a client disputes an invoice that’s been factored?

Invoice factoring is a vital financial tool used by many UK businesses to improve cash flow by selling outstanding invoices to a financial provider. While this speeds up access to funds, it also introduces a third party—the factor—into your client relationships. When a client disputes an invoice that has been sold on, the process becomes more complex, requiring careful management to maintain both client trust and financial stability.

What Happens if a Client Disputes an Invoice That’s Been Factored?

When a client raises a formal dispute regarding an invoice that has been factored, the primary process shifts from debt collection to dispute resolution. The factor, who now legally owns the debt, cannot generally force payment if the debtor claims the goods or services were never delivered, were faulty, or breached the contract terms. Since the factor is only responsible for collecting the money owed, not verifying the quality of your output, the responsibility for fixing the commercial problem always reverts back to your business.

The Immediate Steps Following Notification

In a standard factoring arrangement, there is a clear protocol that both the factor and your business must follow as soon as a dispute is raised:

• Factor Notification: Upon receiving notification of a dispute from the client (debtor), the factor will immediately cease collection efforts on that specific invoice. They will then formally notify your business, usually within 24 to 48 hours, that the debt is disputed.
• Invoice Segregation: The disputed invoice is typically removed from the factoring facility. It is classified as an “ineligible debt,” meaning the initial advance you received against it is now potentially repayable.
• Your Responsibility to Resolve: Your business must take charge of resolving the commercial issue that caused the dispute. This often means addressing complaints about faulty products, poor service, or contractual misunderstandings.
• Communication Restriction: Often, the factor’s agreement stipulates that you must not undermine the factor’s position or directly negotiate the monetary value of the debt without their prior consent, though you are free to resolve the underlying service issue.

Understanding the Types of Disputes

Not all disputes carry the same risk. Factors generally categorise disputes based on the reason for non-payment, which affects who is ultimately liable:

Commercial Disputes (Your Business’s Liability)

These are the most common disputes and relate to the quality or delivery of the goods or services provided. Examples include:

• Damage or defects in the delivered products.
• Service not completed or failure to meet agreed specifications.
• Incorrect pricing or miscalculation of VAT.
• Breach of contract terms by your business.

If the client’s claim is valid, the factor expects your business to issue a credit note or otherwise resolve the commercial issue, effectively reducing or cancelling the outstanding debt.

Credit Risk Disputes (Factor’s Liability, usually only in non-recourse)

This relates specifically to the client’s ability to pay, not their willingness to pay. This means the client agrees the invoice is valid but cannot pay due to financial distress or insolvency. This is only relevant if you have a non-recourse agreement (discussed below).

The Critical Role of Recourse vs. Non-Recourse Factoring

The financial consequences of an unresolved dispute are entirely dependent on the type of factoring agreement you have in place.

Recourse Factoring

The vast majority of factoring agreements in the UK are recourse factoring. Under a recourse agreement, your business retains the risk of non-payment. If the client fails to pay the factored invoice, for any reason (including commercial dispute or simple refusal to pay), your business is obliged to buy the invoice back from the factor.

Consequences under Recourse:

• If the dispute remains unresolved past a specific term (the “recourse period,” typically 90 or 120 days), the factor will demand repayment of the initial advance you received, plus any associated fees or interest.
• This repayment may be taken directly from your factoring reserve account or offset against advances due on new, undisputed invoices.
• If the dispute is settled by issuing a credit note, the factor adjusts the ledger accordingly, and the outstanding balance of the advance must be reconciled.

Non-Recourse Factoring

Non-recourse factoring offers protection against bad debt—specifically, if the client becomes insolvent or bankrupt and cannot pay. However, it is a crucial misunderstanding to assume non-recourse covers all disputes.

Important Clarification: Non-recourse protection typically only covers the financial inability of the debtor to pay (credit risk). It almost never covers commercial disputes (e.g., faulty goods or incomplete services). If the client disputes the invoice because of poor quality, the factor will still return the invoice to you, and your business must resolve the issue and repay the advance.

Managing and Resolving the Disputed Invoice

Prompt action is essential once a dispute is flagged. Delaying resolution can strain your relationship with both the client and the factor, potentially leading to increased fees or termination of the facility.

Step 1: Investigation and Documentation

Upon notification, your team must thoroughly investigate the client’s claim. Gather all relevant documentation, including contracts, delivery notes, correspondence, and evidence of service completion. Clear documentation is paramount, especially if the dispute leads to legal action.

Step 2: Communication with the Client

Your business needs to liaise directly with the client to resolve the commercial disagreement. This may involve:

• Rectifying the service or replacing faulty goods.
• Offering a partial refund or discount.
• Negotiating a new payment term for the corrected invoice amount.

Once an agreement is reached, this resolution must be formally communicated to the factor.

Step 3: Finalisation and Reconciliation

If the invoice amount is reduced (via a credit note), the factor updates the ledger, and the reduction is offset against your reserve account or repaid by your business. If the dispute is entirely baseless and the client eventually pays the full amount, the invoice reverts to its normal factored status. If the client refuses to pay despite your attempts to resolve the issue, under recourse factoring, the debt will be returned to your balance sheet.

If you encounter complex commercial disputes that require structured negotiation, organisations like the Advisory, Conciliation and Arbitration Service (ACAS) offer excellent guidance on resolving workplace and commercial disagreements, which can be helpful in framing your internal processes for dispute resolution.

The Impact on Your Factoring Reserve

Most factoring agreements involve a reserve amount—a percentage of the invoice value retained by the factor until the client pays. When a dispute arises, this reserve acts as a crucial buffer.

If the factor has advanced you £8,000 against a £10,000 invoice (20% retained as reserve), and the dispute is unresolved, the factor will typically use the reserve to cover their advance. If they return the invoice to you, they claw back the £8,000 advance. If you have other reserves held on undisputed debts, the factor may deduct the advanced amount from those funds.

People also asked

What happens if the client disputes the invoice but eventually pays it?

If the client disputes the invoice but subsequently settles the full amount, the factoring process simply continues. The factor releases the remaining reserve to your business, minus their fees. The initial dispute notification is withdrawn, and the debt is no longer considered ineligible.

Does a dispute affect my credit rating?

A single commercial dispute over a factored invoice typically impacts your business relationship with the factor and your cash flow, but it does not directly affect the company’s statutory credit rating, provided you uphold your obligations to the factor (i.e., repay the advance if required under a recourse agreement). However, if disputes become frequent or unresolved, the factor may increase fees, tighten terms, or withdraw the facility, which could force your business into more expensive borrowing options.

Can the factor sue the client over a disputed invoice?

Yes, since the factor legally owns the debt, they have the right to pursue legal action against the client for payment. However, factors are usually reluctant to initiate expensive legal action if the dispute is commercial (e.g., poor quality goods) rather than simply a refusal to pay valid debt. If the dispute is commercial, the factor will almost always require your business to resolve the underlying issue first, or they will return the debt to you.

What is the factoring reserve account used for?

The factoring reserve is the portion of the invoice value the factor holds back until the client pays (typically 10% to 20%). The reserve safeguards the factor against shortfalls, such as if the client pays late, takes early settlement discounts, or if a factored invoice needs to be returned to your business due to an unresolved commercial dispute or credit default.

Conclusion: Maintaining Good Commercial Practice

The experience of handling a disputed factored invoice highlights the necessity of maintaining robust commercial practices. Factoring facilities are designed to finance good, collectable debt. They cannot solve fundamental operational issues, such as poor quality control or inadequate customer service.

To mitigate the risks associated with factoring disputes, businesses should ensure that client contracts are clear, delivery documentation is rigorous, and a proactive system is in place for addressing client complaints quickly. By resolving the root cause of the dispute efficiently, you minimise the time the invoice remains ineligible, reducing the risk of having to repurchase the debt and ensuring your vital cash flow remains stable.
