Which fee system adjusts based on the client’s willingness to spend on a project?

The percentage based on project construction cost fee system is designed to align the financial interests of the client and the provider with the overall budget and scope of the project. Under this system, the fee charged is a predetermined percentage of the total costs of the construction project. As the budget increases or decreases based on client preferences and spending capacities, the fee adjusts accordingly. This means that if a client is willing to invest more into a project, the fee will proportionately increase, reflecting the added budget.

This fee structure is particularly beneficial in scenarios where project scope might expand or where additional features are requested, as it allows for flexibility in budgeting while ensuring that the service provider is compensated fairly for the value of the work performed relative to the total project expenditure. Clients appreciate this system because it allows for better financial planning based on their willingness to invest in project quality and features, making the overall project dynamic and responsive to client needs.
