Our managed IT services are designed to remove the stress from IT. You pay a predictable monthly fee, and we take care of the rest. Here’s what’s included:

At Reliable Computers, You’ll speak with technicians who live and work in the same area, not an overseas help desk. Our skilled engineers resolve issues quickly, aiming for first-touch solutions to ensure your satisfaction.
Our technicians hold current certifications and continually update their skills. Being a Microsoft Solutions Partner means we can support both Windows and Mac environments and advise on Microsoft 365 best practices.
No two businesses are the same. We listen to your needs and design an IT support plan that fits your size, budget and goals.

IT support is an ongoing service where a team of technicians monitors and maintains your systems, fixes issues and keeps everything running smoothly. IT solutions usually refer to one‑off projects such as installing a new server, moving to the cloud or setting up a backup solution.
Our support covers remote and onsite assistance, security and patch management, backup and disaster recovery, Microsoft 365 administration, network and Wi‑Fi configuration, and liaison with third‑party vendors. We also offer cloud migration, cybersecurity auditing and project delivery if needed.
We primarily serve small and medium‑sized businesses in Oatley, the St George region and greater Sydney. Some of our clients have no internal IT staff; others have an IT manager and rely on us for additional expertise. We support Windows and Mac environments and a wide range of industries, from retail and hospitality to professional services and construction.
