For many UK businesses, the biggest cashflow problem is not a lack of sales — it is waiting to be paid. The average UK SME waits 37 days beyond agreed payment terms to receive payment, and for businesses in sectors like manufacturing, recruitment, and construction, outstanding invoices can run into hundreds of thousands of pounds. Invoice finance is the most direct solution to this problem: it lets you access up to 90% of the value of an invoice within 24 hours of raising it, rather than waiting 30, 60, or even 90 days for your customer to pay.
How Does Invoice Finance Work?
Invoice finance is a form of asset-based lending where a lender advances money against your unpaid sales invoices. The process follows four straightforward steps.
- 1You raise an invoice to your customer as normal.
- 2You submit the invoice to your invoice finance provider.
- 3The provider advances you up to 90% of the invoice value — typically within 24 hours.
- 4When your customer pays, the provider releases the remaining balance minus their fee.
The lender's security is the invoice itself — the legal right to receive payment from your customer. This means invoice finance is available to businesses that may not qualify for a traditional bank loan, including fast-growing companies, businesses with limited assets, and those with seasonal revenue.
The Two Main Types of Invoice Finance
Invoice finance comes in two primary forms, and understanding the difference is important when choosing the right product for your business.
Invoice Factoring
With factoring, the lender takes over the management of your sales ledger and collects payment directly from your customers. This is sometimes called 'disclosed' factoring because your customers will know you are using a finance provider. Factoring is well suited to businesses that want to outsource their credit control function, freeing up time and resource.
Invoice Discounting
Invoice discounting works in the same way financially, but you retain full control of your sales ledger and collect payment from your customers yourself. This is 'confidential' — your customers do not know you are using a finance provider. Invoice discounting is typically available to more established businesses with robust internal credit control processes.
| Feature | Factoring | Invoice Discounting |
|---|---|---|
| Customer awareness | Yes — disclosed | No — confidential |
| Credit control | Managed by lender | Managed by you |
| Typical minimum turnover | £100k+ | £500k+ |
| Best for | Growing businesses, limited admin resource | Established businesses with strong credit control |
| Advance rate | Up to 90% | Up to 90% |
What Does Invoice Finance Cost?
Invoice finance has two main cost components.
- Service charge (or management fee): typically 0.5%–3% of your annual turnover, covering the administration of the facility.
- Discount charge: an interest rate applied to the funds you draw down, typically 1%–3% above base rate.
The total cost depends on your turnover, the quality of your debtor book, the sector you operate in, and the lender you choose. Using an independent broker like Amber Finance means you can compare rates from 50+ lenders to ensure you are getting the most competitive terms for your specific circumstances.
Tip: Always compare the total cost of the facility — not just the headline advance rate. A lender offering 90% advance at a higher service charge may cost more overall than one offering 85% at a lower rate.
Who Is Invoice Finance Suitable For?
Invoice finance is most commonly used by B2B businesses that invoice other businesses or public sector organisations on credit terms. It is particularly well suited to:
- Manufacturing companies with long production and payment cycles
- Recruitment agencies funding weekly payroll against monthly client invoices
- Construction businesses with extended payment terms
- Wholesale and distribution companies with high invoice volumes
- Professional services firms with large project-based invoices
- Fast-growing businesses that have outgrown their overdraft
Invoice Finance vs Bank Overdraft
Many businesses default to a bank overdraft as their cashflow tool of choice, but invoice finance often offers significant advantages.
| Invoice Finance | Bank Overdraft | |
|---|---|---|
| Grows with your business | Yes — facility scales with turnover | No — fixed limit |
| Security required | Invoices only | Often personal guarantee or assets |
| Approval speed | Days | Weeks to months |
| Availability | Available to most B2B businesses | Subject to credit history and bank relationship |
| Typical advance | Up to 90% of invoice value | Fixed limit regardless of sales |
