onsite

Onsite refers to something that is located at or performed at a particular place, typically the primary site of a project, facility, or client. It contrasts with off-site or remote activities, which occur elsewhere. The term can be written as on-site (hyphenated) in many style guides, though onsite is also widely used, including in branding and certain corporate communications.

In practice, onsite describes work or services delivered at a client’s location or a project site. Examples include on-site inspections, on-site installation, on-site training, and on-site support. It is common across industries such as construction, manufacturing, information technology, health care, and service sectors. On-site activities can offer direct interaction, quicker issue resolution, and alignment with site-specific requirements, but may involve higher travel and labor costs and logistical considerations.

In project management and operations, on-site personnel are stationed at the project site to coordinate activities, ensure safety, and monitor progress. In data or facilities management, on-site storage or on-site data processing refers to handling information within the physical premises, though increasingly flexible cloud and hybrid approaches can blur these distinctions.
