Watch what our clients say

Here's why we do what we do - our valued clients

Long-term is the wrong term

Tetrabyte Managed IT Agreements are never long-term, just monthly rolling contracts. This means you and your Company have the freedom you want and need. Our Skilled and Speedy Engineers are there to ensure your utmost satisfaction, and our clients stay with us out of choice not because they are tied into a lengthy, auto renewing contract

Available when you need us

Tetrabyte Managed IT is not ‘a log a ticket and call you back service.’ When you call you will speak to our Engineers directly on the phone. Call, Connect, Resolve, it’s that simple.

When ‘Fixed Fee’ means really fixed.

When we say “fixed monthly fee,” we mean it. We don’t believe in surprises at the end of the month. Other IT Support Providers for Business often add costs to your bill such as:

  • Virus Removal : We will never charge to remove a virus infection, even if it requires a full re-install.
  • New computer setup or re-installs : We don’t charge for migrations or additional/new machine setups.
  • New servers and migrations or SharePoint setups : Looking for a new server or want to migrate your entire software over to SharePoint? Setup and migration are all included with us, unlike other providers who may charge a migration fee of over £5000 each time.
  • Consultancy : Planning a new project, new software or moving your Company to another office, we’re always on hand to guide you through the process with instant access to our Engineers who are happy to help - all included as part of our Support as standard.
  • New Software/Hardware setup : Tetrabyte ensures you’re covered without any additional costs with our fixed monthly fee.
  • Out of hours emergencies : Business critical to you, is business critical to us. Tetrabyte go the extra mile to be there for you and never leave you stranded. If the incident is Business Critical, we’ll get you up and running ASAP. We promise a Fixed Monthly Fee and we mean it.
