Operating vs BigTime: Which PSA Should Your Consulting Firm Choose?
TL;DR
Choose BigTime if you are a finance-led enterprise requiring deep project accounting, multi-currency revenue recognition, and GL-grade auditing. Choose Operating for 10–250 person firms prioritizing resource utilization, pipeline-to-capacity forecasting, and AI-native workflows. Operating is built for agility and speed; BigTime is built for financial control.
The data on PSA adoption and scale
Software procurement in professional services often fails because delivery teams reject heavy administrative tools. BigTime is a mature, Vista Equity-backed market leader used by over 2,700 firms to track $8 billion in annual billable time. It is a "fortress" for firms over 300 people that need bulletproof financial compliance.
However, the cost of this control is often administrative debt. Operating is a leaner, AI-native platform designed for speed-to-value, with implementation times measured in days rather than months. In practice, this operational focus leads to higher adoption and better margins. For example, the firm Inventive.io used Operating to reduce unbilled work from $250,000 to $25,000 by fixing inefficiencies in their staffing loop.
Choosing by your operational center of gravity
The decision rests on whether your binding constraint is financial auditing or delivery agility.
When to choose BigTime (The Finance-First PSA)
BigTime wins when the CFO is the primary sponsor. It is an absolute powerhouse for preventing revenue leakage in firms with complex milestone billing, deferred revenue, or multi-entity global consolidation. If you are a 500-person firm with a strict requirement for DCAA compliance or deep Sage Intacct integration, BigTime might be better suited.
When to choose Operating (The Operations-First PSA)
Operating is designed for the COO or Head of Staffing. It treats resource management like a strategy game rather than a database update. It is currently the only PSA with a live Model Context Protocol (MCP) server, allowing AI agents like Claude or ChatGPT to read utilization data and write back staffing allocations directly. For firms under 250 people that live in HubSpot, Operating provides a cleaner pipeline-to-capacity view without the enterprise bloat.

Frequently asked questions
Does Operating replace my accounting software? No. Operating is an "operations layer" that pushes data to QuickBooks or Xero for the heavy lifting. BigTime acts as "ERP-lite" and handles more of the accounting sub-ledger natively.
Which tool is better for a HubSpot-centric firm? Operating was built to integrate with modern CRMs like HubSpot. It pulls deal probabilities and translates them into tentative resource demand instantly, allowing sales to see delivery risks before a contract is signed.
Can an AI agent run my staffing meetings? Only with Operating. Its MCP server allows you to ask Claude who is on the bench next week with specific skills and have the AI create the team plan natively. BigTime is currently building these agentic workflows but is trailing in production readiness.
What is the vendor risk for Operating? Operating is a younger, founder-led firm with a smaller team compared to the PE-backed scale of BigTime. For firms over 300 people, this vendor-risk asymmetry is a real procurement factor that must be underwritten.
