The best software for a consulting firm depends on size: Klientele for 5-30 person firms wanting operations + billing + portal in one system, Mavenlink/Kantata for 50+ person firms needing enterprise PSA, Rocketlane for firms focused on client onboarding delivery.
Consulting firms bill time-and-materials, fixed-fee, and retainer engagements simultaneously — often across multiple currencies and jurisdictions. Most under-30-person firms run a project tool + time tracker + billing tool + spreadsheet for utilization. Above 30 people, they typically move to a full PSA (Mavenlink, Kantata), which brings capability but also 3-6 months of implementation.
We built Klientele. We still tell you when a competitor is the better fit for your specific situation.
