Architects play a crucial role in shaping the built environment — and the commercial viability of that role depends on pricing work accurately. Cost estimation in architecture is a multidimensional challenge: it involves materials, labour, equipment, permits and the unpredictable scope changes that characterise complex projects.

This article examines why precise costing matters, where traditional methods fail and how time tracking software addresses each of those failures specifically.
