The Cost of “Making Do”: Why Legacy Systems Are Costing Australian Construction Firms Millions

Technology adoption in Australia's construction industry is accelerating, and the data confirms it.

A Deloitte report found that, out of 16 different digital technologies, the average construction business has adopted 6.2 technologies, such as AI, machine learning, and many more. 

And yet, investment alone isn't solving the problem. 

Despite growing tech investment, only 37% of businesses are leveraging these technologies.  Many construction firms continue to struggle with: 

• Tight margins 

• Cost overruns 

• Compliance pressure 

• Delayed or inaccurate decision-making 

So, what's holding them back? It's a disconnected system. Businesses are still relying on: 

• Spreadsheets

• Legacy accounting software

• Siloed reporting tools that don't talk to each other

When financials, procurement, and project data live in separate systems, real-time visibility disappears. And without visibility, profitability suffers. 

This is where Microsoft Dynamics 365 Business Central steps in. For construction companies looking to replace legacy systems, this cloud-based business management platform brings clarity and control back to decision-making. 

Why Traditional Systems Don’t Keep Up 

Spreadsheets and legacy accounting software; do they seem familiar to you? But in today’s construction environment, they create real operational pain. Here’s how: 

1. No Real-time Job Costing 

Midway through a multi-million-dollar project, materials are late, invoices pile up, and labour hours are not updated. Manual tracking with spreadsheets and legacy accounting software delays finance, and by the time overruns are noticed, the project is already losing money. 

2. Blind Spots Across Projects 

Managing multiple sites with scattered spreadsheets gives only snapshots, not real-time insights. As a result, decisions on delays, resource allocation, or costs often come too late. 

3. Finance & Site Teams in Silos

Office and site teams work in separate systems. Updates on equipment costs or delays do not reach finance quickly. It leads to errors, disputes, and delayed invoicing. 

Therefore, legacy systems aren’t just inefficient, but they: 

• Shrink margin 

• Create compliance issues 

• Offer no real-time visibility 

• Delay project delivery 

Now, what construction firms need is a single platform that centralizes the data and offers real-time visibility to stakeholders.
