Project costing software is primarily focused on the estimation and tracking of project costs, and is tailored to businesses like construction, engineering, IT services, and professional services.
Project accounting software, on the other hand, provides a broader view of finances, integrating cost management with other financial aspects like revenue recognition and billing.
A project costing system therefore includes tools for real-time cost monitoring, earned value management, and profitability analysis specific to projects, whereas project accounting solutions support the complete financial lifecycle of a venture, from budgeting and expense tracking to invoicing clients.
Project accounting includes general ledger, accounts payable/receivable, payroll, and financial reporting functionalities, and is particularly important for businesses that need to align their endeavors with general accounting standards and practices, including compliance with GAAP or IFRS.
