Bigtime

BigTime is a cloud-based Professional Services Automation (PSA) platform developed by BigTime Software, designed to help service-based organizations manage projects, track time and expenses, and automate billing and financial workflows. Founded in 2002 and headquartered in Chicago, the platform is widely used by consulting firms, accounting firms, IT services providers, and law firms to manage the full lifecycle of client engagements from initial scoping through invoicing and revenue recognition. BigTime centralizes operational and financial data into a single system, enabling firms to connect project delivery with financial performance. By linking time tracking, resource management, budgeting, and billing, the platform provides real-time visibility into utilization, profitability, and project health. This supports more accurate forecasting, faster billing cycles, and improved decision-making across finance and operations teams. The platform is delivered as a SaaS solution and is designed to scale with growing organizations, offering modular capabilities that range from core time tracking and invoicing to more advanced features such as resource planning, multi-entity financial management, and analytics.
