The best software for a consulting firm depends on size: Klientele for small firms (up to 20 users) wanting engagements, time, billing and a client portal in one system, and a dedicated professional services automation (PSA) platform such as Kantata for firms that outgrow that.
Consulting firms often bill time-and-materials, fixed-fee and retainer engagements at the same time. Small firms tend to run a project tool, a time tracker, a billing tool and a spreadsheet; larger firms move to a full PSA, which brings capability but also a long implementation.
We built Klientele. We still tell you when a competitor is the better fit for your specific situation.

Klientele plans cover up to 20 users and do not forecast resources. Larger firms, or firms that need resource forecasting across many consultants, should look at a dedicated PSA; Kantata is one, priced by quote.
Retainers, time-and-materials, fixed fees and milestones: Klientele handles these on the Team and Agency plans. Deferred revenue and enterprise revenue recognition: consider a full PSA.
Professional Services Automation (PSA) software combines project management, resource planning, time tracking, expenses and billing for consulting and professional services firms. Klientele covers the client-facing part of that for small firms: requests, engagements, time, billing and a client portal. Kantata is a PSA built for professional services businesses.
