BigTime vs Kantata — Key Differences

|---|---|---|
| Origin & Focus | US-based, financial management core; evolved from time tracking to full PSA | Originally Mavenlink + Kantata UX; positioned as "modern alternative" |
| Primary Audience | A/E/C + Professional Services; 10–500 seat deployments | Professional services + IT/services firms; stronger in creative and consulting verticals |
| Pricing Model | Per-user/month, quote-based; True Sky enterprise tier | Per-user/month, quote-based; lower entry point than BigTime |

| ERP Integration | QuickBooks, Sage, Dynamics, NetSuite connectors | NetSuite, Sage, Microsoft Dynamics (native); Mendix low-code layer |
| Implementation Time | 4–12 weeks (QuickStart program available) | 6–16 weeks (longer with ERP connector complexity) |
| AI / Intelligence Layer | BigTime Intelligence (bi-directional, 2024); Project Management AI (2025) | Kantata AI — insights, risk flags, resource optimization |
| Reporting Depth | Strong financial + project reporting; built-in for utilization, WIP, revenue | Portfolio-level visibility strong; financial reporting requires more configuration |
| Ideal For | Firms that need billing-first PSA with tight financial controls | Firms that prioritize resource planning and cross-project visibility |
BigTime's Financial Management Advantage
BigTime's financial management module is the most mature in the PSA space. For firms where billing accuracy, revenue recognition, and WIP tracking are non-negotiable, BigTime's integration between time tracking and project billing produces cleaner financials with less manual reconciliation.
The 2024 BigTime Intelligence launch brought bi-directional AI insights that surface utilization gaps and project risk flags — competitive with Kantata's AI layer. Implementation speed is a real advantage. BigTime's QuickStart program gets most firms operational in 4–8 weeks, which matters when you're managing partner expectations on a new system rollout.
Kantata's Portfolio Visibility Edge
Kantata's portfolio-level visibility is genuinely superior for firms managing multiple concurrent projects across service lines. If your project managers spend significant time figuring out "where does this project actually stand," Kantata's unified workspace surfaces that faster.
The Mendix-based customization layer enables low-code workflows that can adapt to firm-specific processes without requiring a full development team.
Kantata's resource management engine handles skills-based booking and capacity planning more intuitively than BigTime's resource module. For firms where utilization optimization is a primary value proposition to clients, this is a meaningful difference.
What Neither Platform Tells You
Neither BigTime nor Kantata automatically tells you where your margin is leaking.
- Both platforms give you utilization rates and project budgets. Neither gives you the automated diagnostic that says: "This project is 23% under-recovered because your billing rate doesn't cover overtime, and here's the adjustment needed to hit margin targets."
- That's the layer AIERPnav adds on top of either PSA — whether you're on BigTime, Kantata, or both.
- ERPAIStack's margin diagnostic analyzes your actual utilization, recovery, and cost data — and delivers a specific improvement plan. The kind of insight that typically requires a $5K/mo advisory engagement is available as a self-serve $149 diagnostic.
