Smart Debtor Finance Around Progress Claims For Builders And Tradies

Using debtor finance around progress claims lets construction and trade businesses turn approved claims into earlier cash, rather than waiting 30–60 days for head contractors or developers to pay. Done well, it smooths cashflow, keeps subcontractors and suppliers paid on time, and reduces the pressure to dip into your home loan redraw or offset as working capital. Done badly, it can magnify disputes, lock you into expensive funding, and quietly threaten the family home.

In this guide, we’ll focus on how builders, subcontractors and trades can use debtor finance specifically around progress claims – when it works, when it doesn’t, and how to structure it so your business and personal finances stay safe.

Mapping progress claims against cashflow is the starting point for safe debtor finance.

1. Why construction cashflow is different – and where debtor finance fits

Construction and trade cashflow is lumpy by design. You often:

• Pay wages weekly and subcontractors fortnightly.
• Pay materials upfront or on 7–30 day terms.
• Wait 14–60 days to be paid on progress claims, with retentions held back.

As explained in detail in Construction Cashflow 101: Progress Claims, Retentions And Funding Gaps, that timing gap means you’re permanently funding part of each job.

1.1 Debtor finance in plain English

Debtor finance (also called invoice finance or factoring) is a working capital facility secured against your accounts receivable. A lender advances a percentage of eligible invoices (say 70–85%) as soon as you issue them or once they’re certified, then you get the balance (less fees and interest) when your customer pays.

For construction and trade businesses, the key twist is that invoices are usually progress claims under a contract rather than a simple one-off sale.

1.2 Why construction firms look at debtor finance

Typical reasons builders and tradies explore debtor finance around progress claims:

• Cover wages and subcontractors while waiting for head contractors to pay.
• Fund materials and variations on larger jobs without using personal cash.
• Reduce reliance on home-loan redraw or personal offset as a quasi overdraft – which, as we’ve covered elsewhere, concentrates business risk on the family home and complicates tax deductibility (see knowledge facts 8, 11 and 13).
• Support growth when you’ve won bigger contracts but banks won’t lift the overdraft.

The trick is matching the shape of your cashflows to the right blend of invoice finance, overdraft and term debt, not trying to make debtor finance do everything.

2. How debtor finance around progress claims actually works

The mechanics are similar to standard invoice finance, but approval rules are much tighter because construction debtors are riskier.

2.1 Typical eligibility rules for construction progress claims

Most lenders will want to see:

• Commercial (B2B) debtors – not mum-and-dad residential clients.
• Written contracts with clear milestones and claim schedules.
• Evidence that work has been completed to the claimed stage.
• Certification/approval of claims where contracts require it.
• Debtor concentration within agreed limits (e.g. no single head contractor over 40–50% of the ledger).

Many lenders will not fund:

• Claims that are disputed or partially disputed.
• Retentions or very late invoices (e.g. >90 days).
• Claims to related parties or connected entities.

2.2 Step-by-step example

Assume you’re a subcontractor with a $500,000 contract to provide electrical works on a mid-rise residential build. You lodge monthly progress claims as follows:

• Contract terms: 20th EOM, 45 days to pay, 5% retention.
• You lodge a $100,000 progress claim for August.
• Head contractor certifies it on 25 August.
• Payment due mid-October.

With a typical progress-claim debtor finance facility:

1. You upload the certified $100,000 claim to the lender’s portal.
2. Lender verifies it (contract, certification, previous payment history).
3. They advance, say, 75%: $75,000 within 24–48 hours.
4. When the head contractor pays the $95,000 (after 5% retention) in October, the lender:
   • Takes back the $75,000 advanced.
   • Charges fees and interest (say $2,000 indicative – depends on facility).
   • Releases the balance (~$18,000) to you.

You’ve effectively paid a cost to pull forward most of that claim by ~45 days so you can pay wages and suppliers on time.

2.3 What gets funded – claims, variations, retentions

• Base progress claims: Usually fundable once certified.
• Variations: Often higher risk. Lenders want signed variation orders, not verbal agreements.
• Retentions: Generally not funded, because they’re purposely held back to cover defects risk.

One of the biggest traps is building your cost base and cash commitments as if retentions and disputed variations are funded, when they aren’t.

Most lenders will only fund certified or approved progress claims, not disputed amounts.

3. Pros and cons of debtor finance vs overdraft for progress-claim funding

Debtor finance is not the only tool. For many construction firms, the right answer is a blend of:

• Debtor finance for certified, larger B2B claims.
• Overdraft or trade finance for materials and short gaps.
• Term loans and equipment finance for long-lived assets.

3.1 Comparison table

For fast-growing subcontractors under long payment terms, invoice finance is generally better suited than overdrafts because available funding scales with invoice volume instead of being constrained by a static limit (knowledge fact 6).
