BigTime review
Bottom line
BigTime is professional services software that connects quoting, time tracking, resource planning, and invoicing in one platform. Its clearest strength is the direct link between approved billable work and invoices, backed by two-way accounting sync. Watch the per-user cost, which starts at $20, and the fact that full pricing requires a conversation with sales. Firms that bill by the hour or by project and use QuickBooks, Xero, or Sage Intacct should shortlist it.
What is BigTime?
BigTime is professional services automation software for firms that bill for their people's time and projects. It connects time and expense tracking, project and staffing management, quoting, and invoicing so that the margin on a project is visible from the first proposal through final payment. It is built for firms in accounting, architecture, engineering, consulting, IT services, and law, where profit depends on keeping billable work accurate and on schedule.
Day to day, staff record time and expenses, and approved entries feed directly into invoices with the correct rates and billing method, whether time and materials, fixed fee, milestone, or a mix. Managers route invoices through approval workflows before they go to clients. Clients can pay by ACH or credit card from a payment link or a secure portal, and firms can set up autopay for repeat customers. Project leads track budget against actuals and cost to completion, while resource managers use drag-and-drop scheduling with an availability view. An AI assistant called AVA answers how-to questions inside the product.
The typical users are finance teams, project managers, resource managers, and sales staff who write proposals. The product is offered in two tiers: BigTime PSA for growing single-entity firms, and BigTime Enterprise PSA for firms with multiple entities, multiple currencies, and more complex workflows. Pricing starts at $20 per user per month, and a free trial is available. There is no free plan, and the pages do not publish a full price list.
What sets BigTime apart is its focus on professional services economics rather than general accounting. It offers two-way sync with QuickBooks Online and Desktop, Xero, and Sage Intacct, and its quoting tools convert approved quotes into live projects with the budget and staffing carried over. The company was founded in 2002, is headquartered in Chicago, and reports more than 3,000 professional services firms as customers.
