BigTime review
A strong fit for professional firms that need controlled time, expense, and billing workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
BigTime is a cloud-based professional services automation platform for accounting, architecture and engineering, consulting, creative, government contracting, IT services, and law practices. It brings together time tracking, expenses, project and task allocation, billing, invoicing, approvals, reporting, and accounting workflows. Teams can record billable or non-billable time through web and mobile interfaces, submit timesheets, and route entries through manager review. Attendance tracking is available through the mobile timesheet app, while the REST API supports reading and writing BigTime data.
The plan structure expands from core operational controls to more specialized financial and project features. Essentials includes time and expense management, project portfolio management, billing and invoicing management, automatic reconciliation, QuickBooks integration, and an AI Assistant. Advanced adds multi-currency expense management, a custom reporting center, project templates, and custom invoice templates. Premier adds multi-currency invoicing, custom cost and rate management, project budgeting, and multi-level approvals. Enterprise adds custom solutions, Enterprise PSA, Services CPQ, and resource management. This makes the lower tiers suitable for firms prioritizing time and billing, while more complex planning and commercial workflows sit higher in the structure.
BigTime connects with QuickBooks Online and Desktop, Sage Intacct, Xero, Salesforce, HubSpot, Jira, Slack, Google Calendar, Microsoft Outlook, Okta, Lacerte, and Zapier. Those integrations support accounting, CRM, collaboration, identity, scheduling, and workflow connections. The product is a strong choice for professional firms that need disciplined time capture, approvals, expenses, invoicing, and reporting across web and mobile. Firms seeking deeper resource planning or a broader PSA scope should evaluate whether Enterprise capabilities match their operating model; smaller teams may also prefer a product with a free plan.
