On-Premise CRM systems are those systems that are installed and operated from a company's own premises, as opposed to being hosted by a third-party provider. They're also sometimes referred to as "on-prem" CRM systems. On-Premise CRM systems offer several advantages over their cloud-based counterparts. First, they give companies more control over their data. With an on-premise system, businesses can decide where their data is stored and how it's backed up. They also have more control over who has access to their data and how it's used.
