For which situation is the Per Diem fee applicable?

The Per Diem fee is applicable specifically for situations that involve expenses related to travel and daily expenditures incurred while performing work away from the normal place of business. In the case of conducting ocular inspections and attending project-related meetings, professionals often need to travel to different locations, which necessitates covering costs such as meals, lodging, and other daily expenses for the duration of their work away from home or their main office.

This payment structure is typically used in scenarios where the work involves travel and a variable duration of time spent on a project, making it appropriate for situations where professionals are actively engaging with project elements in person. In contrast, preparing reports and providing fixed services do not inherently require travel expenses, thus rendering a Per Diem fee irrelevant in those contexts. Charging based on man-hours usually reflects a different billing practice focused on the actual time worked rather than the travel-related expenses that the Per Diem fee addresses.
