Rendering of Services 

Revenue from service transactions is usually recognised as the service is performed, either by the proportionate completion method or by the completed service contract method.

(i) Proportionate completion method—Performance consists of the execution of more than one act. Revenue is recognised proportionately by reference to the performance of each act. The revenue  recognised under this method would be determined on the basis of contract value, associated costs, number of acts or other suitable basis. For practical purposes, when services are provided by an indeterminate number of acts over a specific period of time, revenue is recognised on a straight line basis over the specific period unless there is evidence that some other method better represents the pattern of performance.

(ii) Completed service contract method—Performance consists of the execution of a single act. Alternatively, services are performed in more than a single act, and the services yet to be performed are so significant in relation to the transaction taken as a whole that performance cannot be deemed to have been completed until the execution of those acts. The completed service contract method is relevant to these patterns of performance and accordingly revenue is recognise dwhen the sole or final act takes place and the service becomes chargeable.
