What Is Invoice Finance? Complete UK Guide (2026)

Invoice finance is a way to release cash tied up in unpaid invoices before your customers pay. Rather than waiting 30, 60, or 90 days for payment, a finance provider advances you up to 90% of the invoice value within 24 hours. When your customer pays, you receive the remaining balance minus fees.

For businesses that invoice on credit terms — particularly in construction, recruitment, haulage, and wholesale — invoice finance can solve cash flow problems without taking on traditional debt. You're not borrowing against future earnings; you're simply accessing money you've already earned sooner.

What is invoice finance?

Invoice finance is an umbrella term for several products that allow businesses to unlock cash from their sales ledger. The two main types are:

• Invoice factoring — the provider advances cash and manages credit control (chasing payment)
• Invoice discounting — the provider advances cash but you keep control of collections (confidential)

Both work on the same principle: you raise an invoice, the provider advances most of the value immediately, and you receive the remainder (minus fees) when your customer pays.

How invoice finance works

Here's the step-by-step process for a typical invoice factoring arrangement:

1. You raise an invoice to a customer for £10,000 with 30-day payment terms
2. You submit the invoice to your factoring provider (usually online)
3. The provider advances you cash — typically 80–90% of the invoice value (£8,000–£9,000) within 24 hours
4. Your customer pays the provider 30 days later (or whenever they pay — could be 60 or 90 days)
5. You receive the balance — the remaining 10–20%, minus the provider's fees (service fee + discount charge)

With invoice discounting, the process is the same except your customer pays you directly (they don't know you're using finance), and you then pay the provider. Discounting is confidential.

Factoring vs discounting — what's the difference?

Factoring is more common and often suits smaller businesses that don't have dedicated staff to chase payments. The provider chases late payers and sends statements on your behalf.

Discounting is usually preferred by larger businesses (£1m+ turnover) that have their own team to chase payments and don't want customers to know they're using finance. It's also cheaper because the provider isn't managing collections.

What does invoice finance cost?

Invoice finance costs have two components:

1. Service fee (or “factoring fee”) — typically 0.5–3% of your annual turnover. This covers administration, credit checks, and collections (factoring only).
2. Discount charge — interest on the cash advanced, usually 2–5% over Bank of England base rate (currently 4.5%). Calculated daily from the date of advance until the customer pays.

For a business with £500,000 annual turnover and 60-day average payment terms, total annual cost might be £8,000–£15,000 depending on sector and provider. This works out to 1.6–3% of turnover.

Who uses invoice finance?

Invoice finance is most common in sectors where payment terms are long and cash flow is tight:

• Construction — subcontractors often wait 60–90 days to get paid while still needing to pay suppliers and labour weekly
• Recruitment — agencies pay temps weekly but invoice clients monthly (30–60 day terms)
• Haulage & transport — fuel and wages are immediate costs, but invoices are often 60+ days
• Wholesale & distribution — buy stock upfront, sell on credit terms
• Manufacturing — raw materials and labour costs come before payment
• Professional services — accountants, consultants, and contractors with monthly or milestone billing

According to UK Finance, over £25 billion in invoice finance was in use across UK businesses in 2025, supporting more than 60,000 companies.

Pros and cons of invoice finance

Advantages

• Immediate cash flow — release cash within 24 hours instead of waiting 30–90 days
• Scales with your business — the more you invoice, the more cash you can access (unlike a fixed overdraft or loan)
• No personal guarantees required (usually) — secured against invoices, not your home
• Outsourced credit control (factoring) — saves time and resources chasing late payers
• Not a loan — doesn't appear as debt on your balance sheet (though accounting treatment varies)

Disadvantages

• Costs can add up — typically 1–4% of turnover annually, with higher-risk sectors paying more
• Not suitable if customers pay quickly — if you already get paid in 7–14 days, the cost may not be worth it
• Factoring isn't confidential — customers know you're using finance, which some businesses prefer to avoid
• Customer creditworthiness matters — providers check your customers' credit, and poor customer credit can reduce advance rates or disqualify invoices
• Long contracts — many providers require 12–24 month commitments with exit penalties
• Recourse risk — if your customer doesn't pay (disputes the invoice, goes bust, etc.), you usually have to repay the advance

Worked example: Construction subcontractor

A plastering subcontractor invoices £50,000 per month to main contractors, with typical 60-day payment terms. Cash flow is tight because labour and materials need paying weekly. They're considering invoice factoring.

For this business, the £15,500 annual cost could be justified if it prevents missed supplier payments, allows taking on more work, or avoids expensive emergency borrowing (overdrafts, director's loans, credit cards).

Who can get invoice finance?

Typical eligibility requirements:

• Minimum turnover: Usually £50,000–£100,000 annually (some providers go lower)
• Business age: At least 6–12 months of trading history (some require 2 years)
• Customers: Must be creditworthy businesses or public sector bodies (not consumers). Providers run credit checks on your customers.
• Invoice terms: Payment terms typically 30–90 days. Longer terms (120+ days) can be financed but at higher cost or lower advance rates.
• Sectors: Most B2B sectors are eligible. Some providers specialize in construction, recruitment, or haulage.

What disqualifies businesses:

• Selling to consumers (B2C) — invoice finance is for business-to-business only
• High proportion of disputed invoices or customers with poor credit (high risk of non-payment)
• Very short payment terms (under 14 days) — not enough time for the finance to be useful
• Retentions over 20–30% (common in construction) — reduces the amount that can be advanced
