Managed IT support for a 20–50 person architecture firm in Australia typically costs between $120 and $180 per user per month, depending on performance requirements, cybersecurity controls, cloud infrastructure design, and the level of strategic IT planning required.
Most mid-sized architecture firms in Sydney should expect an annual IT investment of roughly $30,000 to $110,000, covering proactive support, Microsoft 365 management, cybersecurity protection, backup and disaster recovery, SharePoint governance, and structured technology alignment. Firms operating complex BIM environments, managing large project archives, or coordinating Revit version control and plugin consistency across teams may sit toward the higher end of the range to maintain performance stability and protect intellectual property.
