Invoice finance for construction and trades

Construction invoice finance lets a building or trade business release cash that's tied up in unpaid invoices and applications for payment. A finance provider advances a share of what you're owed, then you (or the provider) collect from the client, and the provider takes its fee when the money comes in. It can help contractors pay crews, suppliers and plant hire while they wait on long payment cycles.

Construction billing doesn't work like a standard invoice, though. Certification, retentions, CIS deductions and contract terms all affect how much a provider will advance and how much of your work it will fund. This guide explains how construction invoice finance works, what it costs, where it fits well and where it doesn't, and the Funding Circle alternatives worth weighing up alongside it.

What is construction invoice finance?

Invoice finance is a way of borrowing against money your customers owe you. Instead of waiting 30, 60 or 90 days for a main contractor or client to pay, you receive a percentage of the invoice value upfront. When your customer pays, the provider deducts its fees and passes on the balance. You can read more about the basics in our guide to what accounts receivable is and how it affects cash flow.

There are two main types, and they differ mainly in who chases the payment.

Invoice factoring

With factoring, the provider buys your invoices and takes over collecting payment from your customer. Your customer will know you're using a finance provider, because they pay the provider directly. This can suit contractors without a dedicated credit control function, as it takes chasing off your plate.

Invoice discounting

With discounting, you borrow against your invoices but keep collecting payment yourself. It's usually confidential, so your clients don't need to know. Providers generally expect you to have solid credit control and bookkeeping in place. Our guide to invoice factoring vs invoice discounting covers the differences in more detail.

Selective invoice finance

Some providers let you finance individual invoices or contracts rather than your whole sales ledger. This can work for firms that only need help on a large job or two, rather than an ongoing facility.

Why construction invoice finance works differently

Many invoice finance providers are cautious about construction, and it's worth understanding why before you apply. The way the industry bills and pays creates more uncertainty about what a provider will actually collect.

Applications for payment and certification

Most construction work is billed through applications for payment, often monthly or at agreed stages. The amount you apply for isn't always the amount you're paid, because a quantity surveyor or contract administrator certifies the value of the work. Providers usually prefer to lend against certified amounts rather than applications, which can mean waiting for certification before you can draw funds.

Retentions

Many construction contracts let the client hold back a percentage of each payment until the work is complete and any defects are put right. This retention can be held for months, sometimes years. Many providers won't advance against retentions at all, so it's worth asking early.

CIS deductions

Under the Construction Industry Scheme (CIS), contractors deduct money from subcontractors' payments and pass it to HMRC as advance payments towards tax and National Insurance. The standard deduction rates are 20% for registered subcontractors, 30% for unregistered subcontractors, and 0% for those with gross payment status.

This matters for invoice finance because the cash you receive may be less than the invoice total. Ask any provider how they account for CIS deductions when they work out your advance. CIS is a tax matter, so speak to your accountant about how it applies to your business.

Contract terms and payment rules

Construction contracts often include set-off rights, liquidated damages and payment notice procedures that can reduce what's paid. The Construction Act (the Housing Grants, Construction and Regeneration Act 1996) makes most "pay when paid" clauses ineffective, meaning a main contractor generally can't make paying you conditional on being paid by the client, except where there's insolvency. Providers will still look closely at your contracts to judge how reliable each payment is. For anything contractual, a solicitor with construction experience is the right person to ask.

How construction invoice finance works, step by step

The exact process varies between providers, but it usually follows this pattern:

1. You complete the work and submit your application for payment or invoice to your client as normal.

2. Once it's certified or approved, you share it with your finance provider, often with supporting documents like the contract and certificate.

3. The provider checks the debt and advances an agreed percentage of the eligible amount, typically within a few days.

4. Your client pays, either to you (discounting) or to the provider (factoring).

5. The provider deducts its fees and releases the remaining balance to you.

How much does construction invoice finance cost?

Costs are usually made up of a service or discount fee, plus interest on the money you draw, and sometimes set-up, audit or exit fees. Our guide to invoice factoring costs explains how these charges fit together.

Advance rates matter as much as fees. Across sectors, invoice discounting advances are usually 70% to 95% of the invoice value, though this varies by lender. Construction advances are often lower, because of the uncertainty around certification, retentions and set-off. 

Costs and terms vary a lot between providers and depend on your business, your clients and your contracts. Compare several offers and do your own research before signing up.

Pros and cons of invoice finance for contractors

Invoice finance can be a practical tool for the right construction business. It also comes with trade-offs that are specific to the industry.

Potential benefits

• Releases cash from certified work, so you're not funding projects out of your own pocket for months

• The facility can grow as your turnover grows

• The invoices themselves are usually the main security, rather than property or plant

• Factoring can take credit control off your hands

Potential drawbacks

• Advance rates for construction can be lower than in other sectors

• Retentions and disputed amounts may not be funded

• Contracts, certificates and regular reporting add admin

• Some agreements have minimum terms, notice periods or exit fees

• With factoring, clients deal with your provider, which some contractors prefer to avoid

Which construction and trade businesses use invoice finance?

Invoice finance tends to suit businesses that invoice other businesses, work on credit terms and have a steady flow of certified work. That includes:

• Subcontractors and specialist trades, such as groundworks, electrical, mechanical, roofing and fit-out firms, who often wait longest to be paid

• Main contractors managing several projects with staggered payment schedules

• Infrastructure and specialist contractors, including those working on utilities, telecoms and cell tower installation, where large, milestone-based contracts can create long gaps between outlay and payment

• Trade suppliers and merchants selling materials to contractors on account

It's less likely to suit businesses that mostly work for homeowners, get paid on completion, or have a small number of invoices each month.

Business structure matters too. Many trades operate as sole traders, but a lot of lenders, including Funding Circle, work with limited companies and LLPs. It's worth checking eligibility before you apply anywhere.

Funding Circle alternatives to construction invoice finance

Invoice finance is one way to manage the gap between doing the work and getting paid, but it isn't the only one. If retention, certification delays or low advance rates make it a poor fit, Funding Circle's range can help you cover costs without tying your funding to individual invoices. Our guide to what finance is right for your business covers the wider picture.

Funding Circle business loans

A Funding Circle business loan gives you a lump sum that you repay in fixed monthly instalments. It doesn't depend on individual invoices or certificates, so retentions and set-off don't affect how much you can borrow. Longer terms can fund growth, such as taking on a bigger contract or a new team, while shorter-term loans can help bridge a cash flow gap while you wait on a large payment. Our guide to late payments explains how a working capital loan can cover costs while you chase what you're owed.

FlexiPay

FlexiPay gives you a simple credit reserve to use as and when you need it, working around your needs. You use it to pay a business cost straight away, such as a materials order, plant hire bill, VAT or a subcontractor invoice, then choose to repay over 1, 3, 6, 9 or 12 months. There's no interest, just a flat fee from 1.99% per transaction, and as you repay, your available credit tops back up for next time.

For contractors, that can mean paying a supplier on time, or taking an early-payment discount, while you wait for a certificate to be paid. Unlike invoice finance, it doesn't depend on who owes you money.

Cashback business credit card

A business credit card can help with everyday site spending, like fuel, tools and small materials orders. The Funding Circle Cashback business credit card offers up to 42 days interest-free when you clear your balance in full each month. It also earns cashback on business spending: 2% for the first 6 months or up to £2,000, whichever comes first, then 1% after that. You can add company cards for site managers and team members, each with its own spend limit.

Asset finance

If cash is going on plant, vehicles or equipment, asset finance can spread the cost over time rather than paying upfront. Funding Circle's asset finance marketplace works with a panel of specialist lenders offering a range of deals across plant and construction equipment, including diggers, cranes, access platforms and commercial vehicles. You can also explore options to raise capital against plant and equipment your business already owns. Our guide to preparing for peak construction season looks at this in more detail.

Supporting construction cash flow with Funding Circle

Waiting to be paid is part of construction, but it doesn't have to hold your business back. Funding Circle doesn't offer invoice finance, but our range gives you other ways to pay your team and suppliers on time, take on new work and keep projects moving while certificates and retentions come through.

• Business loans: borrow up to £750,000, with decisions in as little as 5 minutes

• FlexiPay: pay upfront, then repay over 1 to 12 months for a flat fee from 1.99% per transaction

• Cashback business credit card: turn site spend into savings, with 2% cashback for the first 6 months or up to £2,000, whichever comes first, then 1% uncapped

• Asset finance: find deals on plant, machinery and vehicles through our panel of lenders

To apply, your business needs to be a UK limited company or LLP. You'll need at least 1 year of trading history for business loans, FlexiPay and the Cashback business credit card, and 2 years for asset finance. If you're a limited company or LLP, checking your eligibility won't affect your credit score.

Construction invoice finance FAQs

Can I get invoice finance against construction retentions?

Many providers won't advance against retentions, because the money is held back until completion or the end of the defects period. Some specialist providers may consider it, usually at a lower advance rate. Check how any provider treats retentions before you commit.

Is construction invoice finance the same as factoring?

Not quite. Factoring is one type of invoice finance, where the provider collects payment from your customer. Invoice discounting is the other main type, where you keep collecting payment yourself and your clients usually don't know you're using finance.

Can subcontractors use invoice finance?

Yes, subcontractors are among the most common users, as they often wait longest to be paid. Providers will look at your contracts, the main contractor's payment record and how CIS deductions affect what you receive.

How quickly can I get funds from construction invoice finance?

Setting up a facility can take a few weeks, as providers review your contracts, clients and ledger. Once it's running, advances against approved invoices are usually paid within a few days. Timescales vary between providers.

Can sole traders get construction invoice finance?

Some invoice finance providers work with sole traders, but eligibility varies. Funding Circle works with UK limited companies and LLPs, so sole traders aren't currently eligible for our products.

What's the difference between invoice finance and a business loan?

Invoice finance is linked to specific unpaid invoices, so the amount you can draw goes up and down with your sales ledger. A business loan gives you a fixed lump sum repaid over a set term, regardless of who owes you money. Each suits different situations, so it's worth comparing both.
