Questions
IT support in Tustin: common questions
Do you come on site in Tustin?
Yes. We are based in Irvine, which borders Tustin, and visit on site for hardware, network and server work. Everyday support is remote.
Our server is old. Should we replace it or move to the cloud?
It depends on your applications, your internet connection and your budget. The free review looks at what the server actually does and gives you the options in plain language, with a fixed quote for whichever you choose.
Can you take over from our current IT provider?
Yes. A handover starts with documentation: accounts, passwords, licences, backups and network details, so nothing is lost in the change.
What does it cost?
It depends on users, devices, servers and cloud services. The first 30-minute review is free, and you get a fixed, written quote before any work starts.
