CAL licences (Client Access Licence) are necessary in many cases in order to have a fully legal licensing. At CHEAPFY you can buy CALs for Windows server, RDS, SQL server and Exchange Server, with documentation and traceability.

Why do you need a CAL (Client Access Licence)?

CALs are used to grant access rights, either to users and/or devices, to the server in question. This means that when we buy a licence (Windows Server, SQL server or Exchange Server) we have the right to install one of these systems on the server, but it does not give us the legal right for others to connect to that machine. This is why CALs are needed.

One thing to keep in mind is the version of the CAL licences, as they allow us to access systems of the same or earlier versions, not later ones. For example: Buying Windows server 2019 User CAL licenses we will be able to access a server licensed with Windows server 2019, Windows server 2016 and Windows server 2012, but we will not be able to access if the server is licensed with Windows Server 2022.

Depending on the needs and infrastructure of the company, one type of CAL or another will suit us.

Types of CAL


User CAL licences are linked to each user who is going to access the server; using services such as file printing, storage… regardless of the different devices they use.

It is the best option for companies with users who need to access the corporate network with different devices, or when these devices are unknown. We will save costs with this type of CAL if the number of devices exceeds the number of users.


This type of CAL licence is tied to the device. Instead of licensing users, we license per machine regardless of the number of users using it.

This would be the recommended licensing option in companies where there are more users than devices; for example, if workers use the same device on different shifts, as might be the case in a contact centre company.
