Senta

What We Like

  • Excellent value significantly cheaper than Karbon

  • Includes client portal at no extra cost
  • UK-built with UK compliance in mind

Watch Out For

What does this mean in practice?

For a team of 10, Karbon would cost approximately $590/month (roughly £470 at current exchange rates), while Senta would cost £120/month. That is nearly four times the price. For smaller firms, this difference is hard to justify unless the additional workflow power and email triage features directly translate into saved hours. For larger firms where efficiency gains compound, Karbon's investment pays for itself more quickly.

Which Should You Choose?

The right choice depends on your firm's size, budget, and workflow complexity. Here is our recommendation for each scenario.

For Firms 10+ Staff

Karbon

Karbon is the stronger choice for growing and mid-sized firms. The workflow automation, email triage, and team workload visibility provide the structure larger teams need to stay on top of deadlines and client work. The higher cost is justified by the productivity gains at scale.

For Budget-Conscious Firms

Senta

Senta delivers roughly 80% of the practice management capability at a fraction of the price. For firms where budget is a real constraint, Senta offers remarkable value. The built-in CRM, client portal, and email automation engine punch well above their weight for the monthly cost.

For Email-Heavy Firms

Karbon

If your firm is drowning in client emails and struggling to keep inboxes under control, Karbon is the clear winner. The email triage feature routes incoming messages directly into the relevant workflow, eliminating the chaos of shared inboxes and missed communications.
