BigTime Software
BigTime helps professional services firms automate time tracking, billing, and resource management.
BigTime Software is a cloud-based Professional Services Automation (PSA) platform that manages the complete financial project lifecycle for professional firms—from quoting and time tracking through revenue recognition and invoicing. The platform serves 2,700+ firms tracking over $8 billion in billable time annually across accounting, architecture, engineering, consulting, creative, government contracting, IT services, and law. BigTime differentiates through strong G2 rankings (first place in PSA category in 2020-2021), deep QuickBooks integration, and recent AI-powered automation via its AVA orchestrator, though some users note constraints in retainer billing flexibility and resource planning clarity.
Problem solved
Professional services firms lack integrated visibility into billable time, project profitability, and resource availability, forcing manual processes that delay invoicing and reduce gross margins.
Target customer
Mid-market to enterprise professional services firms (accounting, architecture, engineering, consulting, legal, IT services) with 20-500+ employees needing integrated time tracking, project accounting, and billing automation.
