Invoice Finance UK: How It Works, Costs, and Whether It's Right for Your Business

You've done the work. You've sent the invoice. Now you wait 30, 60, maybe 90 days for payment. Meanwhile, your bills don't wait.

Invoice finance solves this timing problem. Instead of waiting for clients to pay, a finance provider advances most of the invoice value upfront. When the client eventually pays, the provider takes their fee and forwards the remainder.

It's the most natural form of business lending because the debt is backed by a real obligation, money your client already owes you.

How Invoice Finance Actually Works

The process follows a consistent pattern across providers:

• You complete work and issue an invoice to your client
• You submit the invoice to your finance provider
• The provider advances 70-90% of the invoice value (usually within 24 hours)
• Your client pays the invoice on normal terms
• The provider deducts their fee and releases the remaining 10-30% to you

The advance percentage depends on your industry, client creditworthiness, and the provider's risk appetite. Professional services typically get 85-90%. Construction gets 70-80% due to higher dispute rates.

Invoice Factoring vs Invoice Discounting

These are the two main variants and the difference matters significantly.

Invoice Factoring

The finance provider takes control of your sales ledger. They chase payment from your clients directly. Your clients know you're using a factoring service because correspondence comes from the provider.

Pros: Saves time on credit control. The provider's expertise often results in faster payment collection. Good for businesses without a dedicated accounts team.

Cons: Your clients know, which some view negatively. You lose control over the collections relationship.

Best for: Smaller businesses that want outsourced credit control. Businesses with high invoice volumes and limited administrative capacity.

Invoice Discounting

You maintain control of your sales ledger. You collect payments as normal and settle with the provider once your client pays. Your clients don't know you're using the service.

Pros: Confidential. Maintains your client relationships. Full control over collections.

Cons: You still need to manage credit control in-house. May require minimum annual turnover (often £500,000+).

Best for: Larger businesses with established credit control processes who want to keep the arrangement private.

What Invoice Finance Costs

Costs typically include two elements:

Service charge: 0.5-3% of the invoice value. This covers administration, credit checks, and (for factoring) collections work.

Discount charge: Applied to the amount advanced, calculated daily until the invoice is paid. Similar to interest, usually 1-3% above base rate.

Example calculation:

• Invoice value: £10,000
• Advance: £8,500 (85%)
• Service charge: 1.5% = £150
• Discount charge: 6% APR on £8,500 for 45 days = £63
• Total cost: £213 (2.13% of invoice value)
• You receive: £10,000 - £213 = £9,787

On an annual basis, if you're running £500,000 through an invoice finance facility, costs might range from £10,000 to £20,000 per year. That's the price of getting paid immediately instead of waiting.

Which Businesses Benefit Most?

Invoice finance works best when:

• Your clients are creditworthy businesses (not consumers)
• Payment terms are 30+ days
• Cash flow timing is your primary challenge, not profitability
• You're growing and need working capital to fund increasing orders
• You want to avoid traditional debt on your balance sheet

It works poorly when:

• Your clients regularly dispute invoices
• Payment terms are already very short
• You have a small number of low-value invoices
• Your clients are consumers (most providers only finance B2B invoices)

Choosing a Provider

Key questions to ask:

Minimum commitments: Some providers require you to finance all invoices (whole turnover facility). Others let you choose specific invoices (selective invoice finance). Selective options offer more flexibility but cost more per invoice.

Contract length: Beware of long lock-in periods. Some providers tie you in for 12-24 months with notice periods. Others offer rolling monthly contracts.

Credit limits per client: Providers set maximum funding limits per customer. If your largest client represents a big chunk of revenue, ensure the limit accommodates your needs.

Bad debt protection: Some facilities include credit insurance. If your client doesn't pay, the provider absorbs the loss. This "non-recourse" factoring costs more but eliminates your biggest risk.
