Hourly billing: According to the workload and the time required, the fee is charged on an hourly basis, which is suitable for more flexible projects and can be adjusted according to the actual workload.
Fixed fee: A fixed fee is determined in advance based on the complexity of the project, technical difficulty and expected hours of work. This approach is suitable for situations where the project is relatively clear and the workload is predictable.
Phased Payment: The entire project is divided into different phases, and the appropriate fee is paid upon completion of each phase. This ensures that the project stays on schedule and reduces risk.
