Comparison

The best Kantata alternatives for boutique consulting firms.

Kantata (the Mavenlink and Kimble merger) is a capable enterprise PSA. It is also heavy, per-seat, and built for organisations much larger than most boutique consulting and IT services firms. Here are six alternatives, ranked honestly by what each is actually for. Yes, we build the first one; the notes on the others are still straight.

01

ConsultancyOS

Consulting operating system
Best for

Firms of 5 to 100 staff that want the operate layer plus an AI delivery layer

ConsultancyOS covers the operate layer Kantata is known for (projects, time, billing, resourcing, forecasting) and adds the one thing no PSA has: an AI delivery layer that encodes the firm's method into agents which produce the first 60% of client deliverables. Flat fee per firm rather than per seat, so systematising does not inflate the bill. The honest caveat: it is built for boutiques, not 2,000-person enterprises, and it is currently onboarding a founding cohort.

02

Scoro

Work management + PSA
Best for

Agencies and small services teams that want one broad work-management suite

Scoro folds projects, quoting, time, billing and light CRM into a single tool, and handles the quote-to-cash flow well for smaller teams. It is broader and lighter than Kantata, at the cost of PSA depth in resourcing and financials. Per-seat pricing.

03

BigTime

Time-and-billing-first PSA
Best for

Firms whose pain is time capture, billing and invoicing

BigTime (which acquired Projector) is strongest at the money mechanics: time, expenses, billing and invoicing, with projects and resourcing layered on. Lighter to adopt than Kantata, and a solid choice when billing accuracy is the main problem to solve. Per-seat pricing.

04

Productive

Agency management platform
Best for

Agencies and digital services firms focused on project profitability

Productive is a modern, well-designed platform covering budgeting, projects, resourcing, time and profitability reporting. It is a genuinely good Kantata alternative for agency-shaped businesses; consulting firms with heavier methodology and delivery needs will find it operations-only. Per-seat pricing.

05

Rocketlane

Client onboarding & PSA
Best for

Client-facing delivery teams where the customer experience is the priority

Rocketlane leads with polished client onboarding, portals and collaborative project delivery, and has been adding PSA capabilities. Strong where the client-facing surface matters most; firm-level forecasting, margin and cashflow are not its centre of gravity. Per-seat pricing.

06

Accelo

Service ops (PSA + CRM)
Best for

SMB service businesses that want CRM and delivery operations joined up

Accelo unifies sales, projects, tickets, retainers, time and billing, and is popular with agencies and MSPs that want pipeline and delivery in one system. Broader than Kantata at the SMB end, without an encoded delivery layer. Per-user, per-product pricing.

Common questions

Kantata alternatives, answered.

Why do firms look for Kantata alternatives?

Three reasons come up consistently: Kantata's depth suits mid-market and enterprise services organisations, so it can feel heavy for a boutique; implementation and change management take real investment; and per-seat pricing grows with headcount. Firms also increasingly want an AI delivery capability, which no traditional PSA provides.

What is the best Kantata alternative for a small consulting firm?

It depends on the job. For the whole firm plus AI delivery, ConsultancyOS. For one broad work-management suite, Scoro. For billing-first operations, BigTime. For agency profitability, Productive. For client onboarding experience, Rocketlane. For joined-up CRM and service ops, Accelo.

Is Mavenlink the same as Kantata?

Yes. Mavenlink merged with Kimble to form Kantata, so evaluations of either land on the combined Kantata platform today. This list applies equally to firms searching for Mavenlink or Kimble alternatives.
