A reliable IT company is the cornerstone of any business. You rely on your IT systems completely, after all, so you will be somewhat crippled as a business if you aren’t able to look after your IT systems properly. All of your information is in there, and is going to be valuable to you for your business needs.
If you are going to use an external company for your IT work, they need to be trustworthy, carrying out regular backups and systems checks. Reviews are very telling – see what other people have been saying about the company to find out whether their IT services are worthwhile. You should talk to them in great depth about what you need before you enter into any contract, to make sure they fully understand what is going to be involved for your business. If there is anything you need regularly, like systems checks or hosting services, let them know upfront.
