What renumeration method is particularly suited for engagements with intermittent personal service?

The per diem or hourly basis remuneration method is particularly suited for engagements that involve intermittent personal service because it allows for flexibility in billing based on the actual time spent on the service. This method is advantageous when services are not required on a continuous basis and can vary significantly in terms of duration and frequency.

Using a per diem or hourly rate makes it easy to match the payment with the specific hours worked or days engaged in the service. This approach is ideal in scenarios where the need for service fluctuates, allowing the service provider to charge accurately for the time they have dedicated to the client. It benefits both parties, as clients only pay for the actual time the service was provided, which is especially useful when service demands can be sporadic or unpredictable.

Other remuneration methods, such as retainers or full-time supervision, imply a more ongoing commitment or continuous engagement which may not be efficient or appropriate for situations where personal services are required intermittently. Reimbursable expenses, while relevant in certain contexts, do not specifically address the payment for labor or service time itself, making them less suitable for this particular scenario.
