Companies use project cost management software to track the profitability of the projects they undertake. This software helps businesses estimate the costs of various projects, monitor actual expenditures, and compare them to projected costs to determine profit margins. Project managers and project control officers rely on this tool to ensure projects stay within budget. Accountants also use it to monitor costs at both the project and portfolio level, breaking down expenses by resource type (e.g., labor, materials). Project cost management software can be offered as part of a broader project management or project and portfolio management suite. It may also be included in project-based ERP systems, which often feature integrated cost management tools. When sold separately, these solutions can integrate with other systems, including project, portfolio, and program management software, ERP platforms, and accounting systems.
