KEY FACTS

  • Service fee: a percentage of invoiced turnover for running the sales ledger
  • Discount charge: interest on funds drawn, priced as a margin over Bank Rate
  • Other charges can include arrangement, audit, refactoring, minimum-volume and termination fees
  • Non-recourse cover adds a credit protection charge

The two main charges: service fee and discount charge

Invoice factoring costs usually combine a service fee charged on turnover with a discount charge on money advanced. The service fee is a percentage of invoiced turnover for running the sales ledger. It relates to the administration of invoices, collection activity and ledger management rather than to the amount of funding drawn. Because the charge is linked to turnover, its absolute cost moves with sales volumes and the number of invoices processed. The percentage applied can reflect workload, debtor profile and contract terms, but no particular percentage is stated in the available facts. The discount charge is different in nature. It is interest on funds drawn, priced as a margin over Bank Rate. The charge applies to money advanced against invoices and is therefore linked to the amount and duration of funding. A business that draws more, or draws for longer, faces a larger discount charge than one with lower or shorter drawdowns, assuming the same margin and Bank Rate. The two elements sit alongside each other in the overall price. Each charge therefore has a separate calculation base and a separate cost driver.

The two charges operate alongside each other, so a comparison based on one element does not capture total factoring cost. The service fee percentage and the discount margin may be quoted separately, and each has a different base. The service fee uses invoiced turnover as its base. The discount charge uses funds drawn and time as its base. A change in sales affects the service fee base, while a change in funding usage affects the discount charge base. Non-recourse cover adds a credit protection charge, which is separate from the service fee and discount charge. Arrangement, audit and exit fees may also apply. The pricing of the discount charge is expressed as a margin over Bank Rate, so Bank Rate movements feed into the discount charge. The service fee is not described in the available facts as linked to Bank Rate. A clear reading separates turnover-based charges from funding-based charges and keeps add-on charges distinct. This separation matters when a client reviews an illustration or a contract because a total cost figure may combine charges with different bases and different triggers.

Set-up, audit and administration charges

Beyond the service fee and discount charge, a factoring arrangement can carry set-up and administration charges. An arrangement fee may be charged for establishing the facility. Legal costs may arise in connection with documentation and security. Audit fees may apply where the factor reviews records or debtor information before or during the facility. Payment transfer charges may apply to the movement of funds between parties. Debenture costs may arise where security is created or registered. The available facts identify arrangement, audit, refactoring, minimum-volume and termination fees as possible charges, and the section points add legal costs, payment transfer charges and debenture costs. These items are fee categories rather than rates, and no amounts are stated here. Their presence means that a headline service fee or discount margin does not by itself describe the full cost. Some charges may be one-off, while others may recur during the life of the contract. The timing and trigger for each charge can differ, so the total effect depends on the facility terms and on the events that occur. A review of the fee schedule separates one-off items from recurring items.

Administration charges can attach to particular services or events rather than to turnover or drawdown. A payment transfer charge relates to the handling of funds. An audit fee relates to review work. A debenture cost relates to security documentation or registration. An arrangement fee relates to the establishment of the facility. Legal costs relate to documentation and security. These charges may be quoted as fixed amounts or as reimbursement of costs, but no rates or amounts are given in the available facts. The contract and fee schedule are the places where the triggers are set out. A charge that appears minor at the outset can add to the annual cost if it recurs or if it applies to each transaction. The relevant question is whether a charge is one-off, event-based or recurring. A factor may also charge for refactoring, which is a change to the facility terms. Minimum-volume and termination fees sit in a different category because they depend on contract performance or exit rather than on routine administration. The distinction affects how the total charge is estimated over time.

Minimum terms, minimum volumes and exit fees

A factoring contract can include minimum terms, notice periods and exit provisions that affect total cost. A minimum term sets the period during which the facility is expected to run. A notice period sets the time required to end the arrangement. A termination fee may apply if the contract ends before the agreed point or outside the agreed process. A minimum-volume requirement sets a level of turnover or invoiced volume that the client is expected to introduce. If the actual volume falls below that level, a minimum-volume shortfall charge may apply. These terms are contractual and no particular lengths, notice periods, volumes or amounts are given in the available facts. The relevant provisions are found in the facility agreement and fee schedule. They matter because a charge can arise from contract performance rather than from a service actually used. Minimum-volume terms can create a cost that is separate from the service fee base, because the charge may be triggered by a shortfall rather than by activity. Notice periods can affect the timing of an exit and therefore the period over which charges continue.

At exit, the treatment of outstanding invoices and debts becomes part of the cost and administration review. A factoring agreement may provide for the re-assignment of debts to the client when the facility ends. The terms can affect what remains with the factor and what returns to the client. A termination fee may be separate from any charge linked to minimum volume. The contract may set out notice requirements and the point from which termination takes effect. The available facts identify minimum-volume and termination fees as possible charges, and the section points refer to re-assignment of debts at exit. No amounts or periods are stated here. The practical effect is that an early exit or a volume shortfall can produce charges that do not appear in a simple comparison of service fee and discount charge. A full review reads the exit clause with the fee schedule. The client can then identify whether an exit charge is fixed, event-based or calculated by reference to the remaining term or to volume. That separation supports a like-for-like comparison of offers across contracts and terms.

Eight cost checks before signing

  1. Ask for the total cost: a worked annual figure on real turnover, not headline rates
  2. Check the minimum volume: shortfall fees can apply in quiet months
  3. Read the notice period: exit can be costly without notice
  4. Price the audits: frequency and fee per audit
  5. Check refactoring terms: what happens to invoices left unpaid
  6. Confirm Bank Rate linkage: how the discount charge moves with Bank Rate
  7. Compare recourse terms: non-recourse cover costs extra
  8. Look for hidden extras: CHAPS, BACS and admin charges

Comparing factoring costs with late payment rights

Comparing factoring costs with late payment rights requires a clear separation between contractual funding costs and statutory remedies. Invoice factoring costs usually combine a service fee charged on turnover with a discount charge on money advanced, priced above Bank Rate, plus possible arrangement, audit and exit fees. Those charges arise from the factoring facility and relate to administration and funding. Statutory late-payment interest is different. UK law lets suppliers charge late payers statutory interest of 8% above Bank Rate plus fixed compensation of £40 to £100. The statutory right is a remedy directed at a late payer. It is not a charge levied by the factor for running the facility. A supplier can therefore face factoring charges and, at the same time, hold a statutory late-payment claim against a customer. The figures are not directly interchangeable because they have different legal bases and different payers. The comparison is therefore about cost and recovery, not about two versions of the same charge. A supplier can recover statutory interest from a late payer only where the conditions of the late payment regime are met.

The late payment regime is directed at suppliers with a claim against a late payer. The statutory figures are 8% above Bank Rate and fixed compensation of £40 to £100. The factoring discount charge is priced as a margin over Bank Rate on funds drawn. Both can move with Bank Rate, but the statutory rate is set by law and the discount margin is set by the factoring agreement. The service fee is a percentage of invoiced turnover. The statutory compensation is not a service fee and does not depend on turnover. The two amounts serve different purposes. One is a contractual price for administration and funding. The other is a statutory remedy for late payment. A comparison that places them side by side without noting the different legal bases can misstate the annual cost of factoring. The statutory right belongs to the supplier that has provided goods or services and has not been paid. The factoring charge belongs to the commercial arrangement between the client and the factor. A total-cost review keeps the two ledgers separate and clearly distinct.

How Bank Rate changes affect factoring costs

The discount charge is the element of factoring cost most directly linked to Bank Rate. It is interest on funds drawn, priced as a margin over Bank Rate. When Bank Rate changes, the discount charge can change by a corresponding amount, subject to the terms of the agreement. If the margin is fixed, a rise in Bank Rate raises the discount charge and a fall lowers it. The service fee is a percentage of invoiced turnover and is not described in the available facts as linked to Bank Rate. The statutory late-payment rate is 8% above Bank Rate, so it also moves when Bank Rate moves. That statutory rate is a separate legal measure. The Bank of England publishes Bank Rate, and the link matters because a floating discount charge transmits Bank Rate movements into the cost of funding invoices. A client that reviews a factoring illustration can ask how often the discount charge is reset and which Bank Rate reference applies. Those contractual details determine the timing and size of any change. A fixed margin does not remove Bank Rate risk; it leaves the reference rate as the variable element.

Bank Rate movements affect the discount charge through the margin over Bank Rate. A change in Bank Rate alters the interest cost on funds drawn, so the total factoring cost can rise or fall even when the service fee base and the client's turnover are unchanged. The effect depends on the amount drawn and the time for which funds are outstanding. A larger drawdown over a longer period carries a greater sensitivity to Bank Rate than a smaller or shorter one, assuming the same margin. The service fee may remain unchanged because it is calculated on invoiced turnover. Non-recourse cover adds a credit protection charge, which is a separate element. Arrangement, audit and exit fees are not described in the available facts as Bank Rate linked. A cost review therefore separates the Bank Rate linked discount charge from turnover linked and event based charges. The Bank of England's published Bank Rate is the reference point for that link. The contractual margin and reset terms determine how quickly a movement is reflected in the charge for the client under the facility.

Disputes, complaints and where to go

A dispute about a factoring facility can arise over charges, contract terms, administration or exit. The route for a complaint depends on the status of the business and the subject matter. The Financial Ombudsman Service has jurisdiction over certain complaints involving micro-enterprises. That jurisdiction is not a general route for every business dispute, and the available facts do not set out the full eligibility tests. UK Finance standards may be relevant to the conduct and handling of the matter. The Small Business Commissioner provides a route in relation to late payment. A late-payment issue between a supplier and a customer is distinct from a complaint about a factor's charges. The two routes address different relationships. A neutral review identifies the subject of the dispute and the body with the relevant jurisdiction. The complaint route also depends on whether the issue concerns the factor's service, the contract or a customer's payment conduct. A record of correspondence and charge notices supports a factual account. The available facts do not state time limits or detailed procedures for each body and route in practice.

The Financial Ombudsman Service route concerns complaints within its jurisdiction, including certain complaints involving micro-enterprises. UK Finance standards may inform expectations about conduct in the market. The Small Business Commissioner route concerns late payment. These routes do not determine the price of a factoring facility. They provide dispute and complaint channels where the relevant conditions are met. A business can keep the issues separate by identifying whether the complaint is about the factor's charges or about a customer's late payment. The first may fall within a complaints route for financial services. The second may fall within the late-payment route. The available facts do not provide detailed procedures, time limits or outcomes. A factual account of the charges, contract terms and payment history supports any route. The distinction matters because a complaint about a customer's payment conduct does not become a complaint about the factor merely because the invoice has been factored. Equally, a complaint about a factor's charge is not a late-payment claim against the customer. The relevant body and the relevant legal basis are identified clearly separately and distinctly.
