A utilization contract, in contrast to the flat-rate contract, is an agreement for making payments based on the volume of services delivered by the provider. The amount paid for each unit delivered is as per the service rate established in the contract. For example, the contract can state that the provider will deliver a physiotherapy service at the rate of $100 for each unit delivered. So for each session of physiotherapy service delivered by the provider within the contract period, the agency pays $100. The rates defined in the utilization contract are used for making payments against the invoices and rosters submitted by the provider.
