Cost management is one of the core aspects of project management. The project costs are estimated and planned in the form of a budget as part of project planning. Budget compliance is monitored throughout the project. Project cost accounting is required for budget compliance, as it provides necessary information about costs incurred, cost trends and possible causes of costs incurred in all phases of a project. Project cost accounting in abas ERP can also be used without activating project management to provide further evaluation for accounting.
