8 Best Kantata Alternatives for Service Firms in 2026

Autotask PSA is the other legacy MSP option, and it covers ticketing, project management, billing, contracts, and time tracking in one system. It is part of the Datto stack, now owned by Kaseya, so an MSP that already runs Datto RMM or Kaseya tools gets a familiar integration path. The product suits MSPs that bill by contract and need service level tracking beside the ticket queue.

Like ConnectWise PSA, Autotask PSA is quote-only, so a team cannot budget before a sales conversation. The interface feels dated next to newer tools such as HaloPSA and Syncro, and the implementation takes time. An MSP that wants a published price and a trial should look at HaloPSA first, while an MSP already invested in the Datto and Kaseya stack will find Autotask PSA the natural fit.

HaloPSA is the most configurable PSA in this guide, and it covers the service desk, CRM, project management, billing, contract management, reporting, and time tracking in one per-agent price. The UK pricing page lists £69 per agent per month billed annually, with every module included and no tiers or add-ons, while the US price is $99 per agent per month up to 24 agents. The 30-day free trial gives a team a full month to test the configuration before committing.

The onboarding package is the cost to watch. Halo requires one with every purchase, priced by scope rather than listed, so the first-year total is unknown until you get a quote. Setup also takes time, with reviewers reporting about three months to implement.

Price: £69 per agent/month (billed annually, UK price)

Free plan: Free trial (30 days)

Accelo suits agencies and consultancies that sell client work in several forms, since it offers modular products for sales, projects, service, and retainers. The Plus plan starts at $24 per product per user per month billed annually, with a minimum of 5 users, and Premium starts at $39. Plus covers the client and contact database, tasks, timesheets, and custom fields, while Premium adds scheduling, resource management, rules, templates, approvals, and the client portal.

The per-product price is the detail to check. A team that buys two products pays the per-user price twice, so the total grows fast once several modules are in use. A team of 10 on one Plus product pays $240 per month, but two products cost $480.

Price: Plus $24 per user/month (billed annually)

Productive is the best fit in this guide for agencies and professional services firms that want resourcing beside budgets and billing. The Essential plan at $10 per user per month billed annually covers budgeting, project and task management, time tracking, expense management, reporting, and time off, while Professional at $25 adds rate cards, recurring budgets, advanced reports, and billable time approvals. The Ultimate tier is quote-only, so a team that needs it should ask for a written quote first.

The 3-seat minimum means a solo operator pays for three seats from day one, so Essential starts near $30 per month rather than $10. A team of 10 pays $100 per month on Essential or $250 on Professional. For a firm that leaves Kantata over quote-only pricing, Productive is the clearest switch, since every price is published and the trial opens the full product.

Teamwork suits teams that want resource planning inside a project management tool rather than as a separate PSA. The free plan covers up to 5 users, and Basics at $9.99 per user per month billed annually adds task management, milestones, and workload views. Accelerate at $24.99 adds more reporting, automation, and resource planning depth for teams that run many projects at once.

The trade-off is depth. Teamwork covers tasks, files, and time tracking well, but it does not offer the project accounting and revenue recognition that Kantata is built around. A small consultancy that mainly needs projects and capacity views should start with the free plan, while a firm that needs audit-grade revenue recognition should look at Productive or Scoro instead.

Price: Basics $9.99 per user/month (billed annually)

Free plan: Yes, up to 5 users

Scoro suits agencies and consultancies that want quotes, invoices, and billing beside projects and resourcing. The Essential plan at $26 per user per month billed annually covers projects, calendars, tasks, contacts, quotes, invoices, and dashboards, while Standard at $37 adds resource planning and Pro at $63 adds CRM and advanced reporting. All plans need a minimum of 5 users, so the smallest bill is $130 per month on Essential.

The price is the highest entry point in this guide, and the 5-user minimum rules it out for very small teams. A firm with 10 or more billable people gets a full work management system for the price, with utilization and margin data beside the schedule. A smaller firm should compare Productive Essential at $10 or Teamwork Basics at $9.99 first.

Harvest is the simplest option in this guide for a team that tracks time and wants a light view of capacity. The Teams plan at $9 per user per month billed annually covers time tracking, reporting, invoicing, and expense tracking, while Enterprise at $14 adds more controls and support. The free plan covers 1 seat and 2 projects, which suits a solo freelancer who wants to try the timers before paying.

The limit is depth. Harvest shows who is overbooked and where hours go, but it does not offer the resource forecasting, skills matching, or project accounting that Kantata is built around. A team that plans capacity week by week should treat Harvest as a time tracker with a capacity view, not as a PSA replacement, and should look at Productive or Scoro for the full workflow.

Price: Teams $9 per user/month (billed annually)

Free plan: Yes, 1 seat and 2 projects
