“I bought a new computer from jbhi due to Windows 11 compatibility. Maxwell from Reliable Computers came out and within a very short period of time configured everything from my 9 year old model to the new one. No stress. Repeat- no stress. Maxwell was uber efficient and helpful. Another issue a day later was a new printer that needed to be connected caused me an issue. Vineet from the same company via the phone solved this problem over the phone. Summary: As their name says- reliable.,A stress free experience and I have no hesitation in recommending their services. In 12 months I am getting them to install Office 365. 5 Star Service.”

    What does Microsoft 365 migration for small business Sydney cost? A basic Microsoft 365 Business Basic setup starts around $9 per user per month for licensing, plus a one-off fee for data migration and configuration, which varies by complexity. For example, a local electrical business used to manage files on local drives. We moved their data and emails to Microsoft 365, giving them secure cloud storage and professional email. This upgrade improved their daily operations. Call 1800 753 991 for a free consultation.

    What happens when a domain name expires and someone else registers it? If your business domain name expires, it enters a grace period. If you do not renew it, it becomes available for public registration. A competitor or a cyber squatter could register it, taking over your business online identity and email, causing major disruption and reputational damage. Renew your domain names promptly. Call Reliable Computers on 1800 753 991 to check your domain status or register a new one.
