The short version

  • Each has a real cost: Relativity quote-only and expensive, typically billed on data volume, so costs escalate with matter size; Rocket Matter trust accounting compliance is only included on the most expensive Elite tier, so firms with a regulatory requirement for it face a higher effective floor price than the entry-level plan suggests.
  • They diverge on capability: Relativity covers Large-scale processing, Rocket Matter covers Matter management.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Relativity

  • Quote-only and expensive, typically billed on data volume, so costs escalate with matter size
  • Complex enough that certified specialists are a job title, which is a real staffing cost
  • Considerable overkill for small matters, where lighter self-service tools are far cheaper

Rocket Matter

  • Trust accounting compliance is only included on the most expensive Elite tier, so firms with a regulatory requirement for it face a higher effective floor price than the entry-level plan suggests.
  • It is not built for large enterprise legal departments, so firms above a certain size outgrow it and move to platforms such as Clio or Aderant.
  • The tier structure gates common workflow features like kanban boards and templates behind Pro and above, so the cheapest tier is functionally limited.
  • Its name is easily confused with the Matter smart-home connectivity protocol, an entirely unrelated technology, which can cause mismatched search results.
  • Per-user monthly pricing across four tiers means a growing firm needs to actively reassess its plan as headcount and accounting needs change, rather than a single plan scaling automatically.

Answered from the vendors’ own pages

Relativity: What does Relativity cost?

It does not publish rates. Ediscovery is generally billed on data volume and users, quoted per matter or organisation.

Rocket Matter: Does Rocket Matter include trust accounting?

Only on the Elite tier; the Essentials, Pro and Premier tiers do not include full trust accounting compliance.

Relativity: Is Relativity only for law firms?

No. Corporate legal departments and government agencies use it for investigations as well as litigation.

Rocket Matter: Is Rocket Matter the same as the Matter smart-home standard?

No, that is an unrelated connectivity protocol for smart-home devices; Rocket Matter is legal practice management software.

Relativity: Do I need trained staff?

In practice yes. Relativity certification is a recognised specialism, and that staffing cost is part of the total.

Rocket Matter: What size firm is Rocket Matter built for?

Solo practitioners through mid-sized firms; larger firms typically need a more enterprise-oriented platform.
