Single invoice finance: how selective funding works

What single invoice finance is

Single invoice finance, also called selective invoice finance, advances cash against one chosen invoice rather than the whole sales ledger. The seller keeps the wider debtor book outside the arrangement and selects the invoice or invoices to be funded. The product sits inside the UK invoice finance and asset-based lending market, which UK Finance says provides around £150 billion of funding a year. It is used for business to business invoices, so the debtor is another business rather than a consumer. The focus is on a named invoice and its payment date, not on a general overdraft or a whole-ledger assignment. The arrangement can be short in duration because it follows the selected invoice. Providers include specialist funders, platforms and banks, and the legal and operational terms vary between them. The funder's decision turns more on the debtor's credit quality than on the seller's own accounts, because the receivable is the primary source of repayment. Selective funding leaves the rest of the ledger outside the facility and ties the advance to the chosen receivable. The seller retains ownership of the rest of the debtor book, subject to the terms of the individual agreement.

Whole-ledger factoring usually involves a continuing relationship, an assignment of the sales ledger and collection activity by the funder. Single invoice finance is narrower: it funds one invoice at a time and does not require a whole-ledger assignment. It usually has no minimum term, unlike whole-ledger factoring contracts, so the arrangement can end when the selected invoice is settled. That structure can suit a business that wants to test invoice finance before considering a ledger facility, or that has an isolated receivable rather than a steady flow of eligible invoices. The product is still a form of invoice finance, so it depends on the validity of the invoice, the debtor's ability and willingness to pay, and the funder's verification process. The seller remains responsible for the commercial relationship with the debtor unless the agreement says otherwise. The funder may require notification or may operate without disclosure, according to its terms. The absence of a long contract does not remove the need to read the assignment, recourse and fee provisions. The commercial terms determine which party carries unpaid invoice risk and how disputes are handled. The funder's approval process focuses on the debtor, not the seller's full accounts.

How the process works step by step

The process begins when the seller selects a single eligible invoice, usually a business to business receivable that has been delivered and accepted. The funder assesses the debtor's credit quality, verifies the invoice and checks that the underlying goods or services are not disputed. If approved, the seller assigns the chosen invoice to the funder under the facility documents. The funder then advances a percentage of the invoice face value, with the balance held as a reserve. The advance is tied to the selected invoice rather than to the whole sales ledger. The funder may use a trust or client account structure so that collections are held separately before settlement. Notification of the assignment can be disclosed to the debtor or kept non-disclosed, depending on the terms. Timing depends on verification, debtor acceptance and the funder's onboarding checks; there is no single timetable that applies to every case. If the debtor disputes the invoice, the funder may exclude it from funding, withhold the reserve or require repayment of the advance. The seller usually provides delivery evidence, purchase order and contact details for verification. The funder may contact the debtor to confirm the amount and payment terms.

After the advance, the debtor pays according to the invoice terms. Where notification applies, the debtor is directed to pay the funder or into a designated account. Where notification does not apply, the seller collects and remits funds under the facility. The funder reconciles the receipt, releases any reserve and applies its charges. If payment arrives late, the funder may continue charging for the extended period, depending on the fee structure. A disputed invoice can interrupt the process: the funder may require the seller to replace the invoice, repay the advance or accept a recourse adjustment. Concentration limits may apply if one debtor represents a large share of the funded amount. The seller remains responsible for the commercial performance of the contract and for resolving disputes with the debtor. The final settlement depends on the actual collection date, the amount received and the terms of the assignment. Records of the assignment, notification and collections are central to the process. The funder may also ask for proof of delivery and a copy of the purchase order before releasing the final reserve.

Where it sits in the UK invoice finance market

UK Finance reports that invoice finance and asset-based lending provide around £150 billion of funding a year. That figure covers the broad market, including whole-ledger factoring, invoice discounting, selective invoice finance and other asset-based facilities. The same trade body figures, as cited in the section brief, include over £20 billion in use at any one time and £315 billion of client turnover. These numbers describe the market as a whole, not the selective segment alone. Single invoice finance is a niche within that larger market because it funds chosen invoices rather than the entire sales ledger. The scale of the market means that providers range from specialist funders and platforms to banks with asset-based lending arms. For a business comparing products, the relevant distinction is between a whole-ledger facility and a selective one, not simply between named providers. The £150 billion a year measure is a flow, while the amount in use is a stock at a point in time. Client turnover measures the sales of businesses using the facilities, not the amount advanced. The selective segment is therefore small relative to the reported total.

The reported £150 billion a year and the over £20 billion in use are aggregate figures for invoice finance and asset-based lending. They do not identify how much is selective invoice finance, because published market data does not usually split that product line. The £315 billion client turnover figure describes the annual sales of client businesses, so it is larger than the funding provided. Selective products sit within the same regulatory and commercial environment as whole-ledger facilities, but their usage is more episodic. A business may use selective funding for one invoice, one contract or a seasonal peak, rather than as a continuous ledger facility. That pattern makes the product a narrow part of the market by volume even where it is useful for a specific cash-flow gap. The market context also explains why providers may offer both selective and whole-ledger options, and why terms can vary according to the debtor and the invoice. The figures are context rather than a measure of demand for any single product. They also show that invoice finance is an established source of UK business funding.

Costs and how they are quoted

Single invoice finance is usually priced by a fee expressed as a percentage of the invoice face value. The quote may be a flat per-invoice charge or a combination of a per-invoice fee and a time-based charge for the period until payment. Some funders quote an advance rate and a discount charge; others use a simple fee. The structure matters because the same headline percentage can produce different total costs depending on how long the invoice remains unpaid. A fee quoted for a short period may be extended if the debtor pays late, and the extension terms belong in the facility documents. Charges can also include an application or onboarding fee, a verification cost or a minimum charge, depending on the provider. No single rate applies across the market, so a comparison needs the full fee schedule rather than one percentage. The seller can ask for a worked example based on the invoice value and expected payment date. That example can show the total charge for the expected funding period and the daily cost if payment is delayed. It can also separate one-off costs from recurring charges.

A practical comparison expresses the total charge against the number of days the cash is outstanding. If one quote has a higher per-invoice fee but a lower time-based charge, the cheaper option depends on the actual collection period. A quote that looks low for a 30 day payment term may become more expensive if the debtor pays after 60 days. The seller can model the total cost at the expected payment date and at a later date to see how the fee changes. The comparison can include the reserve release, any minimum period, extension charges and the cost of funding a replacement invoice if a dispute arises. The headline percentage is only one input. The total cost also depends on the advance rate, because a lower advance rate leaves more of the invoice value to be funded from other sources. The fee schedule and the facility agreement set out how charges accrue and when they are deducted. The seller can ask for the charge to be shown in pounds as well as in percentage terms. That makes the total cost easier to compare across different fee structures.

Late payment rights and how they interact

UK late-payment law gives a supplier a statutory right to claim interest on overdue commercial debts. The current statutory rate is 8% above Bank Rate, and the supplier can also claim fixed compensation in a band from £40 to £100 depending on invoice size. Where no payment terms are agreed, statute provides a default payment period of 30 days. The right applies to business to business debts and can be exercised alongside contractual remedies, subject to the terms agreed. The claim is separate from the invoice finance arrangement, but the two interact because the funded invoice may be assigned. The seller and funder need to establish who holds the late-payment right after assignment. The facility agreement may transfer the benefit of the receivable and related rights to the funder, or it may leave the seller to pursue them. The statutory regime is designed to discourage late payment and to compensate the supplier for the cost of waiting. It does not replace the invoice terms; it operates where payment is late and the conditions are met. The calculation uses Bank Rate at the relevant time, so the interest amount can change.

The interaction with single invoice finance depends on the assignment. If the invoice is assigned to the funder, the funder may take the benefit of the debt and the associated late-payment claim, subject to the wording of the assignment. If the seller retains the right to claim, the funder may require the proceeds to be remitted under the facility. A dispute about the invoice can affect both the funding and the late-payment claim. The seller can check the facility agreement for clauses on collections, proceeds and enforcement. The statutory right is not automatic in every case: the contract may set different payment terms, and the parties can agree remedies. Interest and compensation are calculated by reference to the unpaid amount and the period of delay. The funder's fee may continue during that period, so the seller can compare the statutory recovery with the funding cost. The allocation of the claim is a documentary point, not a separate funding product. The funder may also require notice of any claim and may conduct correspondence with the debtor. The seller can keep records of the invoice date, due date and payment terms to support a claim.

When businesses use selective funding

Businesses use selective invoice finance when a single receivable creates a cash-flow gap that is not matched by a steady ledger need. A seasonal peak can produce large invoices before receipts arrive, and funding one or two of those invoices can cover wages, stock or tax payments. A one-off large contract can absorb working capital because the supplier must pay for materials or labour before the customer pays. Selective funding can bridge a supplier deposit, where cash is needed before a purchase order is fulfilled. It can also be used to test invoice finance before a business considers a whole-ledger facility. The product is descriptive of a narrow use case: it follows a chosen invoice, not the entire sales book. The business retains the rest of its debtor book and can decide whether to fund another invoice later. The timing of the invoice, the debtor's payment terms and the seller's cash cycle determine whether the gap is short or long. The arrangement can be used alongside other finance, provided the documents allow it. It does not require a whole-ledger assignment, so the rest of the sales ledger remains outside the facility.

Selective funding can fit a business with a concentrated customer base or a lumpy order book. A manufacturer that receives a large purchase order may need to buy components before the customer pays. A recruitment or consultancy business may have one unpaid invoice that is large relative to its monthly cash needs. A wholesaler may face a seasonal build-up of stock and receivables. In each case, the funder looks at the debtor's credit quality and the validity of the invoice. The product can also sit alongside an existing overdraft or asset finance arrangement, subject to the terms of those facilities. The business can use selective funding for a defined period and then return to its normal working capital cycle. The decision is commercial and depends on the cost of funding compared with the cost of late payment or lost opportunity. The product is not a substitute for a full ledger facility where the business needs continuous funding against many invoices. It is a targeted tool for a specific invoice or a small group of invoices. The seller can plan the use around the expected collection date and the debtor's payment history.

Risks and what to check before signing

Selective invoice finance carries recourse risk if the debtor fails to pay. The facility may require the seller to repay the advance, replace the invoice or absorb a loss. The seller can check whether the arrangement is with recourse or without recourse, and what happens on insolvency of the debtor. Disputes are a related risk: if the debtor alleges that goods were defective or the invoice is incorrect, the funder may withhold funding or require repayment. Concentration limits can restrict how much is advanced against one debtor. Notification can change the debtor's payment behaviour and the commercial relationship. The seller can review the assignment, the collection account arrangements and the funder's rights on default. Fees on extensions can increase the cost if payment is late. The facility agreement sets out the remedies and the notice periods. The seller can check the definition of an eligible invoice and the exclusions for disputed or overdue receivables. The seller can also check whether the funder can vary the advance rate or withdraw funding during the invoice period. A clear record of delivery and acceptance helps to reduce dispute risk.

Before signing, a business can verify the funder's recourse terms, the fee schedule and the process for resolving disputes. The checklist can include the assignment wording, the notification position, the reserve release conditions and the treatment of partial payments. It can also cover concentration limits, the definition of default, the funder's right to audit and the cost of early settlement. The seller can ask for a worked example of the total charge and for the documents that govern collections. The business can check how late payment rights are allocated after assignment and whether the funder pursues them. The facility agreement can set out what happens if the debtor pays directly to the seller. The seller can confirm the position on set-off, counterclaim and credit notes. These points are commercial and legal checks, not a judgment on whether the product is suitable. The seller can also check whether the funder requires notice of any dispute and how quickly the seller must report it. The total cost comparison can include fees on extensions and any minimum charge. Independent legal advice can be used where the assignment terms are complex. The seller can keep copies of the facility documents and the invoice evidence.

Frequently asked questions

Is single invoice finance the same as selective invoice finance?

Yes, both terms describe funding one chosen invoice rather than the whole sales ledger.

Does the customer know about single invoice finance?

Often yes, because payment is usually directed to a funder or trust account, though some providers offer confidential options.

Is there a long contract?

Usually not; each invoice is a separate transaction, unlike whole-ledger facilities with minimum terms.

Who carries the risk if the customer does not pay?

Most selective products are recourse, so the business repays the advance if the customer fails to pay.

Can late payment interest still be claimed?

The Late Payment Act allows 8% above Bank Rate plus fixed compensation; who can claim depends on the funding agreement.
