Architecture and engineering firm business loans: what lenders look at

When a lender looks at an architecture or engineering firm, they aren’t looking at your equipment. They’re looking at your fee income, your debtors, your work in progress and your clients. A design practice owns very little that anyone could sell, apart from some computers, software licences and a plotter. So the loan is really a bet on whether the fees you’ve earned will turn into cash. Show that clearly and a design firm can be a very comfortable borrower.

We’ve looked at a lot of industries, and design practices sit in an interesting spot. They have the cash-flow pattern of a professional services firm and a customer list that runs straight into the construction cycle. Here’s how that looks from the lender’s side of the desk, and how to present your practice so the answer comes back yes.

What do architecture and engineering firms usually borrow for?

The reasons are remarkably consistent across architects, structural and civil engineers, building services engineers, building designers and town planners:

• Payroll ahead of fees. You pay staff every fortnight, but a big project might only invoice at the end of each design stage. Winning a major commission can leave a gap of several months.
• Hiring for a pipeline. Bringing on a project architect or senior engineer before the work is signed is a classic growth squeeze.
• Software and hardware. BIM and CAD licences, modelling software, high-spec workstations and drones for survey work. These are useful, but they’re worth little second-hand.
• Fit-outs and moves. A studio that clients visit is part of the brand, and a fit-out is a lump sum.
• Buying out a partner or buying a practice. This is common as founders retire. It’s usually the largest borrowing a design firm ever does.
• ATO and payroll catch-ups. A slow-paying client can leave BAS or PAYG behind. Lenders consider ATO debt case by case.

Why lenders look at fee income, not equipment

In most industries a lender asks, “If this goes wrong, what can we sell?” For a café it’s the coffee machine and fit-out. For a trucking business it’s the trucks. For a design practice the honest answer is “not much”. (Our guide to specialised equipment and resale value explains why that matters.)

So the lender’s focus moves to the money coming in:

What a lender checks	What they’re really asking
Fee income in bank statements	Is revenue steady, or does it arrive in big, irregular lumps?
Aged debtors report	Who owes you money, and how old is it?
WIP schedule	How much work is done but not yet billable, and when does it bill?
Staff costs as a share of fees	Is there margin left after salaries and super?
Top clients by fee income	What happens if your biggest client stops paying?
PI insurance and registration	Can the firm keep practising?

That’s the same lens a lender uses on a law firm or an accounting practice. There’s one big difference, though: who your clients are.

How do lenders read work in progress and fee stages?

Architectural and engineering fees are usually invoiced by stage. Typical stages are concept design, development application, design development, construction documentation and contract administration. Some engineering work is billed monthly on time and materials, and some on lump-sum milestones.

From a lender’s point of view, unbilled WIP is a promise, not cash. It becomes real when you reach a stage, issue the invoice and the client accepts it. Lenders tend to discount WIP heavily when:

• a project is stalled waiting on a development approval;
• the client has gone quiet or is disputing a variation;
• the fee is paid only “on approval” or “on financial close” of a development;
• WIP has been sitting on the books for months without an invoice.

The fix is simple and makes a big impression: give the lender a one-page WIP schedule. List each major project, the client, the total fee, the stage reached, the percentage complete, the next invoice amount and the expected invoice date. A firm that can produce that page looks like a firm that’s in control of its cash.

Got a big commission landing before the fees do? See if your practice qualifies. Enquiring takes about a minute and doesn’t touch your credit file.

Why does your client list matter so much?

This is the question that makes design firms different from other professional practices. Many architects and engineers are paid by developers and builders, and that part of the economy has had a rough few years. According to ASIC’s insolvency statistics, construction was again the industry with the most companies entering external administration in 2025–26, at roughly a quarter of the total. That was the first annual fall since the post-COVID rise, but it’s still the biggest share by a distance.

A lender will therefore want to know:

• What share of fees comes from developers and builders, compared with homeowners, government, schools, councils, health or commercial owners.
• Whether any one client is more than about a fifth of your income. That’s where concentration starts to worry a credit assessor.
• Whether you’ve been caught by a client insolvency before, and how you handled it.
• Whether fees are paid progressively or held back until a project reaches finance or settlement.

A practice with a mix of government panels, institutional clients and private work will usually be read as lower risk than one doing almost all its work for two or three developers. Even so, a developer-heavy firm with a clean debtors history can make a strong case. Our guide to borrowing when your industry is doing it tough covers how to show you’re stronger than the sector.

Registration and PI insurance: the licence checks for design firms

Lenders check licences because a business that can’t practise can’t earn. For design firms, that means registration and professional indemnity (PI) insurance:

• Architects must be registered with their state or territory board to use the title. In NSW, the Architects Registration Board’s PI factsheet explains that practising architects need suitable PI insurance, and architects who don’t meet the requirement can be removed from the register.
• Engineers in Queensland generally need to be a registered professional engineer (RPEQ), or work under an RPEQ’s direct supervision, to provide professional engineering services in or for Queensland. The Board of Professional Engineers of Queensland sets out the registration path.
• NSW engineers and design practitioners working on buildings covered by the design and building practitioners scheme must be registered, and registered professional engineers and design practitioners must hold PI insurance.
• Victoria has its own registration scheme for professional engineers in certain areas of engineering.

What a lender wants is simple: a current PI certificate, evidence that the principals are registered where they need to be, and an honest note about any open claim. An open claim isn’t automatically a deal-breaker. A surprise one usually is.

A worked example: one big commission, five months of payroll

Illustrative only. The figures are rounded and the firm is made up. A 12-person structural and civil engineering practice in Brisbane wins a large school redevelopment through a government panel. It’s the biggest job the firm has had. It needs three extra engineers straight away, but the first fee stage won’t be invoiced for about four months, and government terms add another month before the money arrives.

Here’s what the firm’s director put together for a lender:

1. Twelve months of bank statements showing steady fee receipts across about 40 clients.
2. An aged debtors report, with most of the balance under 60 days and one older developer invoice explained (it’s on a payment plan).
3. A WIP schedule listing the school job’s fee stages and expected invoice dates.
4. The panel engagement letter, which shows the client is a state government department.
5. A current PI certificate and the RPEQ registrations of the two directors.

The lender’s read: diversified clients, a government payer on the new job, a known timeline and a modest, explained debtor issue. The gap was funded unsecured on the strength of turnover and bank statements. A larger sum, say to also buy out a retiring director, would have pointed toward property security instead.

Common things that slow a design firm’s application

• WIP that’s never been reconciled. A big WIP figure with no project breakdown looks like it’s hiding write-offs.
• One developer owing most of the debtors. Even if they’re good for it, explain the relationship and the payment history.
• Partners drawing more than the practice earns. Lenders compare drawings with profit, especially in partnerships and trusts.
• Lapsed or “pending” PI renewal. Renew first, then apply.
• The wrong industry code. Firms sometimes tick a construction ANZSIC code when “architectural services” or “engineering design and consulting” fits better. Our ANZSIC code guide explains why the label matters.

How to present your practice: a short checklist

• Bank statements (usually 6 to 12 months) and recent BAS.
• Last financial year’s accounts and up-to-date management accounts.
• Aged debtors report, with notes on anything over 90 days.
• One-page WIP schedule tied to fee stages and invoice dates.
• Top ten clients by fee income, with the type of client noted.
• Current PI insurance certificate and evidence of registration.
• A sentence or two on what the money is for and how the fees will repay it.

Designing the next stage of your practice? Let’s see what fits

Design firms are used to planning ahead: stage by stage, with a programme and a budget. Finance works best the same way. Arrange it while the commission is being signed, not when the second payroll lands before the first invoice. We understand fee stages, WIP, developer clients and PI renewals, so you won’t have to explain the basics.

The enquiry takes about 60 seconds, and there’s no credit check when you first enquire. We don’t send your details to a pile of lenders, so your phone won’t start ringing with strangers in the middle of a design review. A real person will look at how your practice actually earns its fees and call you to talk it through. Please fill in the form accurately, including your rough annual fees, any ATO balance and what the money is for. That way we can match the right option the first time.
