Description
One Onsite by Lessen helps vendors and their technicians complete their facilities maintenance work orders successfully while collecting valuable information along the way.
With One Onsite, technicians can see the work they need to do for the day, read through relevant information around the issue, location and historical work done while effectively executing their work on-site with minimal disruption.
Some of the key features around this app include:
· Guided – With its seamless flow, simple language and focus on one task at a time, One Onsite is simple for the technicians to understand, and they require minimal training to use the app
· Informational – One Onsite provides information and photos around the work order, guides the technician to the location that they need to visit and provides relevant historical service information. It also helps the technicians understand what information needs to be provided to their back office based on the trade
· Efficient – One Onsite boasts of a vastly improved tech stack from its predecessor with better performance in offline and low connectivity areas, faster upload times and greater battery optimization
