How does invoice finance work for engineering companies in the UK

Invoice finance can be a genuine lifeline for engineering companies facing cash flow pressures. Whether you're waiting for a major client to pay or managing seasonal demand swings, this form of borrowing lets you access funds tied up in unpaid invoices quickly and easily. We'll walk you through how it works and what it means for your engineering business.

What is invoice finance and why do engineering companies use it?

Invoice finance is a straightforward way to borrow money against unpaid customer invoices. Instead of waiting 30, 60 or 90 days for payment, you can release cash immediately and keep your operations running smoothly. For engineering firms, this is particularly valuable because projects often involve long payment cycles and significant upfront material costs.

• Invoice factoring: a lender buys your invoices outright and handles customer collection
• Invoice discounting: you retain control of collections but borrow money secured against the invoice value
• Common for engineering: industries with B2B clients, longer project timescales and material-heavy work benefit most

Both options unlock cash without taking on new debt in the traditional sense, since the money is backed by real customer orders.

How invoice factoring works

Factoring is the more hands-off option. You sell your invoices to a lender (called a factor), who then chases your customers for payment.

• You raise an invoice to your customer as normal
• You submit it to the factor within a day or two of issue
• The factor advances between 80-90% of the invoice value within 24-48 hours
• Your customer pays the factor directly when the invoice is due
• You receive the remaining balance (minus fees) once the customer has paid
• The factor typically charges 0.5-3% of invoice value, depending on your turnover, customer base and industry risk

This is ideal if your engineering team needs to focus on delivery rather than chasing payments.

How invoice discounting works

Discounting keeps you in charge of customer relationships. You borrow against your invoices but still collect payments yourself.

• You raise invoices and submit them to the lender
• You receive 80-90% of the value upfront, usually within 24 hours
• You keep customer relationships and handle all collection activity
• When your customer pays you directly, you repay the lender plus interest
• Monthly interest charges typically range from 1-4% of the amount borrowed, depending on your credit profile and the lender

Discounting works well if you want flexibility and already have a smooth payment collection process in place.

Key requirements for engineering companies

Most UK lenders have straightforward eligibility criteria. Here's what they typically look for.

• Annual turnover: usually minimum GBP 100,000 to GBP 250,000, though some lenders accept lower
• Trading history: most want you to have traded for at least 6-12 months
• Customer base: lenders prefer invoices owed by established, solvent businesses (not individuals or very high-risk sectors)
• Invoice value: typically individual invoices of GBP 500 or more work best
• Payment terms: invoices with terms between 30-90 days are standard; longer terms may increase fees

Engineering companies generally present lower risk to lenders because project invoices tend to be clear, documented and backed by tangible deliverables.

Costs and fees to expect

Understanding the full cost of invoice finance helps you decide if it's the right choice for your business.

Compare the total cost against the cash flow benefit - if waiting for payment would damage your business, the fees are often money well spent.

The application and approval process

Getting invoice finance approved is faster than a traditional business loan. Most FCA-regulated UK lenders can process applications within days.

• Gather your last 2-3 years of accounts, recent bank statements and current invoices
• Provide details of your main customers and their payment history
• Submit an application form (online or by post)
• The lender reviews your invoices and may contact your customers to verify the debt is genuine
• You receive an approval decision and written terms within 5-10 working days in most cases
• Once you've signed, you can start submitting invoices for funding immediately

Unlike traditional credit checks, lenders focus on the quality of your invoices rather than your personal credit score.
