How can construction companies use invoice finance to manage cash flow
Cash flow problems are one of the biggest challenges facing UK construction companies. Even when you've got plenty of work on the books and profitable projects, you might find yourself short of money between invoicing clients and getting paid. Invoice finance - also called factoring or supply chain finance - can bridge that gap and keep your business running smoothly.
Why construction companies struggle with cash flow
Construction projects don't generate cash in a straight line. You'll typically pay suppliers and staff upfront, but won't get paid by clients until weeks or months later. This gap can create real strain, especially if you're managing multiple projects at once.
- Payment terms - Main contractors and developers often pay on 30, 60, or even 90-day terms
- Project timescales - Cash outflows happen early (materials, labour, plant hire), but income arrives only when invoices are settled
- Growing businesses - Taking on more work actually worsens cash flow before it improves
- Seasonal variations - Weather and project cycles can create unpredictable income patterns
- Retentions - Clients often hold back 5-10% of invoice value until project completion
This mismatch between when you pay out and when you receive money is the root cause of cash flow stress in construction.
What is invoice finance and how does it work
Invoice finance lets you borrow money against the value of invoices you've issued to customers. Instead of waiting weeks for payment, you get access to most of that cash immediately. You then repay the finance when your customer pays the invoice.
Invoice factoring
A factor buys your invoices outright. They handle credit control, chase payments, and assume the risk if a customer doesn't pay (assuming you use non-recourse factoring). This costs more but takes the admin burden off you.
Invoice discounting
You keep control of invoices and credit management yourself. You simply borrow against the invoice value and repay when the customer pays. It's cheaper than factoring but you do the chasing.
Supply chain finance
Your customer (often a large main contractor) approves invoices, and a finance provider pays you early. The customer then pays the finance provider on their original payment terms. This works well when you're a subcontractor to big names.
Key benefits for construction businesses
Invoice finance offers specific advantages that make it popular with construction companies operating in the UK market.
- Immediate cash - Access 75-95% of invoice value within 24-48 hours, not weeks later
- Manage growth - Take on bigger contracts and more projects without waiting for payment
- Predictable costs - Monthly fees are clear and structured, unlike overdraft charges that vary
- No personal guarantees - Most lenders won't ask you to personally guarantee the facility
- Flexible drawdowns - Only pay for invoices you actually finance, not a fixed loan amount
- Meet payroll - Ensure you can pay staff on time, even before clients settle invoices
- Negotiate better terms - With reliable cash, you can sometimes negotiate better rates with suppliers
How to set up invoice finance
Getting started with invoice finance is straightforward. Most lenders complete the process in a few days, and you'll need basic information about your business and customers.
- Choose between factoring, discounting, or supply chain finance based on your needs
- Prepare recent accounts, typically the last 2-3 years of trading
- Provide a list of your customers - especially the main contractors or developers you work with
- Share recent invoices to show the lender what you typically invoice for
- Be ready to discuss any customers with poor payment history
- Agree credit limits with the lender (usually based on your customer list quality)
- Set up a dedicated bank account for the finance arrangement
- Start submitting invoices for financing once approved
Most UK lenders can set you up within 3-5 working days once you've submitted complete information.
What lenders look for when assessing construction companies
Lenders assess construction finance applications based on the strength of your customer base and your track record. Understanding what they're looking for helps you present your application well.
- Customer quality - Large, established main contractors and developers are viewed as low-risk customers
- Payment history - A pattern of on-time payments from your clients reassures lenders
- Trading history - Most lenders want at least 2 years of accounts showing profitable trading
- Business accounts - Clean separation between business and personal finances strengthens your application
- Invoice size and frequency - Regular invoices of £5,000 or more are typical for construction finance facilities
- Sector experience - Lenders specialising in construction understand the sector's normal payment patterns
- Management team - Evidence of experienced, stable management matters for larger facilities
Lenders rarely check your personal credit score when assessing invoice finance - they focus on your customer list and business performance.
Costs and fees explained
Invoice finance costs are transparent and typically lower than overdrafts or unsecured loans. Understanding the fee structure helps you budget accurately.
Interest and discount fees
You'll pay interest on the cash you've drawn, calculated daily on the amount outstanding. This is typically 2-4% per month (or 24-48% annually) depending on your credit risk and the lender. Supply chain finance is often cheaper at 0.5-1.5% per month.
Service fees
Most lenders charge a monthly service fee (typically £100-300 for construction) or a small percentage fee on invoices you finance (0.5-1.5%). Factoring includes credit management, so it costs more - usually 1.5-3% of invoice value.
Arrangement fees
A one-off fee when you set up the facility, typically £200-500. Some lenders waive this for competitive applicants.

Frequently asked questions
Will using invoice finance damage my relationship with my customers?
No. Your customers don't need to know you're using invoice finance unless you choose to tell them. The lender handles collections discreetly in the background, and your customer receives normal invoices from you as usual. Invoice finance is completely standard practice in construction.
What happens if one of my customers doesn't pay an invoice?
With non-recourse factoring, the factor bears the loss - you're protected. With invoice discounting or supply chain finance, you're responsible for repaying the advance if your customer fails to pay, though this is rare with established main contractors. You can discuss credit protection insurance with your lender.
Can I use invoice finance if I'm a new business?
Most mainstream lenders want 2 years of accounts, but some specialist lenders will consider newer businesses if you have strong contracts with established customers. Speak to a broker like Spark Finance who can identify lenders willing to work with newer construction companies.
Is invoice finance expensive compared to a bank overdraft?
Invoice finance typically costs 2-4% per month, while overdrafts often charge similar rates but less transparently. The advantage is that you only pay for what you borrow against actual invoices, not a fixed overdraft limit, making it more cost-effective for growing businesses with variable cash needs.
