Which is best for a mid-size consultancy: Kantata, BigTime or Scoro?
It depends on the job you need done. Kantata suits firms scaling toward enterprise size that need deep resourcing and project financials. BigTime suits firms whose main problem is time and billing. Scoro suits agency-shaped teams that want quoting, CRM and projects in one tool. None of the three produces client work; if you want an AI delivery layer as well, ConsultancyOS adds it.
Kantata vs BigTime for a mid-market consulting firm?
Kantata is deeper on resource management and project financials but heavier and more expensive to implement. BigTime is lighter, faster to adopt and strongest on time, expenses and invoicing. For a 20 to 60 person firm, BigTime is usually the easier start; Kantata earns its weight at larger scale.
BigTime vs Scoro?
BigTime is billing-first PSA built for professional services firms. Scoro is broader work management with quoting and CRM built in, popular with agencies. Consultancies that live on timesheets and invoices tend to prefer BigTime; teams that sell and deliver lots of smaller projects tend to prefer Scoro.
What about NetSuite OpenAir?
OpenAir is an enterprise PSA most often chosen by firms already running NetSuite. It is powerful but heavy for most mid-size consultancies. See our ConsultancyOS vs NetSuite OpenAir comparison for the detail.
