Using Overdraft Facilities in Architecture Firms

As an Architectural business coach and Fractional Practice Manager, I’ve seen the working internals of several firms in different stages of growth.

And one of the surprises I consistently find is how differently directors approach the concept of debt facilities, such as overdraft accounts and unsecured loans.

On the one hand, some practices shy away from debt facilities and self-funding entirely – relying on their practice to fully self-sustain business growth, and on the other hand, I’ve also seen practices with more than $300,000 of overdraft, and several thousand dollars in interest fees every month.

Which one is correct?

I think this is more a matter of ‘horses for courses’, than a matter of right and wrong.

My first ever serious business (read: a business large enough to report to a board of directors) was not actually an Architectural firm – it was a multi-outlet health business. And the nature of payments in that business was almost entirely prepaid. If the client didn’t pay, we didn’t provide the service. And that meant that even though we were a substantial and fairly heavy business, we had no need of overdraft facilities at all. Wonderful!

And to some extent, this is the same world that purely residential Architects live in. They provide services to a client – usually a month at a time – issue and invoice, and then demand payment within 5 to 10 business days. A disciplined Architect will immediately charge interest after 10 days, and stop work within 20 in the event of non-payment. That leaves a residential Architect only $10,000 to $15,000 out of pocket at any one moment, and can be easily covered by good cashflow management without overdraft.

But as the work gets larger, the game changes entirely. As the value of Architectural work increases, work starts to become naturally more ‘speculative’. That is, clients start to have substantial cashflow management issues on their side, and tend to hide the severity from the Architect.

In Multi-residential Architecture and Small-Commercial Architecture, the client is usually heavily leveraged, conducting multiple projects at the same time, and has no intent of paying on time – choosing instead to muscle the Architect for several months while they wait for their own payday.

In this instance, Overdraft facilities seem to become almost essential to cover the 3 to 6 month shortfall, while the clients catch up on payments – often in amounts totalling several hundred thousand dollars of Architectural design fees.

If we, as Architects, use overdraft, how do we avoid falling into a debt trap?

In good times, the chances of falling into a debt spiral are very low. The project will be a success, the client will get their profit, and they will eventually pay the Architect. Great!

But at the time of writing this article, it’s 2026, and the Australian Architectural market – particularly in Melbourne – is collapsing into a ‘quantum state’ of thriving and dying at the same time. Something I haven’t seen since the 2008 recession.

And what I’m starting to see in some of the Architectural firms I have a window into is that the overdraft facilities have become too large, and the clients aren’t paying. It’s been 6 months, and that payday from the client is starting to look like unrecoverable ‘bad debt’.

And here is the debt trap: if your overdraft is ever more than 50% of your aged receivables (outstanding invoices), then there’s a chance that a single bad debt might wipe out your business entirely (technically no amount is safe, but this is an exercise in reality and risk management – not perfection).

If your client owes $100,000 for 6 months, You’ll have paid $6,000 to $12,000 in interest by the time they pay. That’s your entire profit margin.
