BigTime is a standalone PSA built for mid-market professional services firms — consulting, IT services, accounting, and engineering. It handles time tracking, project billing, and QuickBooks/Xero integration, with implementations typically completing in 4–10 weeks at a cost of $20–$35/user/month. NetSuite PSA (formerly OpenAir, now part of Oracle NetSuite) is an enterprise PSA module deeply integrated with the NetSuite ERP suite. It offers multi-entity support, advanced resource planning, and unified financials — but requires 4–9 months and $50,000–$150,000+ to implement, with base platform costs starting around $1,000–$2,000/month plus $100–$200/user/month. The practical dividing line: firms with 10–150 employees that want to move fast and keep their existing accounting system typically choose BigTime. Firms with 150+ employees, multiple entities, or already on NetSuite ERP typically choose NetSuite PSA.

Feature Breakdown
Head-to-Head: Seven Dimensions
Capability
BigTime
NetSuite PSA
Time Tracking
✓ Clean weekly timesheets with flexible approval workflows. Mobile-friendly. Strong QuickBooks sync.
✓ Configurable timesheets with multi-entity, multi-currency, and project charge codes. More complex setup.
Project Billing
✓ T&M, fixed-fee, milestone, and retainer billing. Invoice sync to QBO/Xero. Good for commercial firms.
✓ All contract types plus ASC 606 revenue recognition. Native ERP billing — no sync needed.
Resource Planning
◐ Team scheduling and utilization tracking. Good at firm level; limited for complex multi-project staffing.
✓ Enterprise-grade capacity planning, role-based resource requests, and demand forecasting across entities.
Financial Reporting
◐ Project P&L, budget vs actual, utilization reports. Good operational visibility. No consolidated GL.
✓ Consolidated financial reporting across entities. Real-time P&L tied directly to the GL. CFO-grade.
Multi-Entity / Multi-Currency
✗ Limited. Single-entity focus. Currency support is basic.
✓ Built for multi-entity firms. Full intercompany eliminations and multi-currency natively.
ERP Integration
✓ Native QuickBooks Online, QuickBooks Desktop, and Xero. No NetSuite integration without middleware.
✓ Fully native to NetSuite ERP. No sync required — single data model for PSA and financials.
Time to Value
✓ 4–10 weeks to go live. Most firms can self-implement with guided setup.
✗ 4–9 months typical. Requires an implementation partner. Complex configuration.
Ideal Firm Profiles
Who Should Choose Which
Choose BigTime if…
- You're a 10–150 person consulting, IT, or accounting firm
- You want to keep QuickBooks or Xero as your accounting system
- Time-to-value matters — you need to be live in weeks, not months
- Your firm doesn't have dedicated IT or ERP admin staff
- You bill T&M or fixed-fee and need automated invoice generation
- You're replacing spreadsheets or an outgrown billing system
Choose NetSuite PSA if…
- You have 150+ employees or multiple business entities
- Your firm is already running (or planning to adopt) NetSuite ERP
- You need ASC 606 revenue recognition for complex contracts
- Your PE owner or CFO requires consolidated multi-entity financials
- You've outgrown BigTime's reporting depth and need CFO-grade analytics
- Budget for a 6–12 month ERP rollout is available and justified
The Gap Neither Fills
What If You Don't Need a Full PSA?
Both platforms solve an implementation problem before they solve a visibility problem.
- BigTime requires your team to change how they log time. The system is only as good as the time data going in. Firms that struggle with timesheet adoption see slow ROI — the dashboard looks right but the numbers are six weeks stale.
- NetSuite PSA requires migrating your financial system. You're not adding a tool — you're replacing your accounting infrastructure. That's the right call for large firms. For a 30-person consulting firm, it's frequently overkill.
- What many firms actually need is weekly ops intelligence, not a new time-tracking system. If your existing books have the data and your problem is "I don't have a clear picture of utilization and margin week-over-week," a lighter-weight reporting layer may be the faster path.

Common Questions
Frequently Asked Questions
What is the difference between BigTime and NetSuite PSA?
BigTime is a standalone PSA platform purpose-built for mid-market professional services firms — consulting, IT services, accounting, and engineering. It focuses on time tracking, project billing, and QuickBooks/Xero integration, with implementations typically completed in 4–10 weeks. NetSuite PSA is Oracle's enterprise PSA module, deeply integrated with the NetSuite ERP suite. It offers broader financial management, multi-entity support, and advanced resource planning — but requires significantly more implementation time (4–9 months) and budget.
How much does BigTime cost vs NetSuite PSA?
BigTime pricing starts at approximately $20–$35/user/month, with implementations typically running $5,000–$25,000. NetSuite PSA starts at $1,000–$2,000/month for the base platform license plus $100–$200/user/month, with implementation costs commonly ranging from $50,000–$150,000+ for a mid-market firm. Total first-year cost for NetSuite PSA at a 50-person firm typically runs $150,000–$400,000 when including implementation, customization, and training.
Is BigTime good for a 50-person IT consulting firm?
Yes — BigTime is well-suited for IT consulting firms in the 20–150 person range. It handles T&M and fixed-fee billing, project budget tracking, resource scheduling, and QuickBooks integration without the overhead of an enterprise ERP. Implementation takes 4–10 weeks. The main limitation is that it doesn't include a general ledger, so you'll keep your existing accounting system alongside it.
When should a consulting firm consider NetSuite PSA over BigTime?
Consider NetSuite PSA when your firm has outgrown standalone tools and needs unified ERP + PSA in one system — particularly if you have multiple entities, complex revenue recognition (ASC 606), or are approaching 200+ employees. NetSuite PSA is also the right call if your parent company or PE owner already runs NetSuite financials. The implementation burden is significant, so this decision is rarely made for operational PSA features alone — it's usually driven by broader ERP consolidation.
Does BigTime integrate with NetSuite?
BigTime does not have a native, pre-built integration with NetSuite ERP. BigTime's native integrations are with QuickBooks Online, QuickBooks Desktop, and Xero. Connecting BigTime to NetSuite requires a third-party middleware tool or custom API development, which adds cost and maintenance overhead. If you're already running NetSuite financials, the integrated NetSuite PSA module is often simpler than running BigTime alongside it.
