Where each one fits

Fit language is an evaluation starting point, not a promised outcome.

MyCase

Start here when: Solo and small-to-midsize firms wanting an all-in-one cloud platform with native trust accounting

MyCase fits generalist small firms that want case management, billing, native IOLTA/trust accounting, intake, and client communication in one system without stitching together add-ons. It scores well on ease of use and support, and trust accounting is a genuine built-in strength. Before buying, verify current per-user pricing and annual-commitment terms directly (third-party trackers still show outdated figures), confirm that LEDES/e-billing and court-rules calendaring depth match your practice area, weigh the extra-cost MyCase Accounting add-on for full business accounting, and note the weak mobile-app ratings and the export gap where documents and invoices are excluded from the self-serve backup.

CosmoLex

Start here when: Small-to-midsize US law firms wanting built-in trust and business accounting without running QuickBooks.

CosmoLex is a strong fit for compliance-focused small and midsize firms that want trust and general-ledger accounting native rather than bolted on, and that value one vendor with US-based support. Before buying, verify current per-user pricing directly (base plan prices are not public), confirm whether you need court-rules deadline automation (CosmoLex relies on manual entry plus calendar sync, with no native rules engine documented), and test the limited mobile app and data-export/bank-feed constraints against your workflow.

Strengths and cautions

Interpretation stays tied to accessible vendor evidence.

MyCase

Strengths

  • All-in-one platform covering intake, matters, billing, trust, documents, and client communication
  • Native three-way trust/IOLTA accounting built in rather than via a third-party integration
  • Client portal in every plan; e-signature and two-way texting included from the Pro tier up
  • Free guided data migration and onboarding plus phone/chat/email support included
  • Strong ease-of-use and support ratings on Capterra and G2
  • Same-family LawPay payments give tight, compliant billing-to-payment flow

Cautions to validate

  • Full business accounting is a paid add-on ($39/user/mo) on top of the plan
  • Court-rules/deadline automation is limited natively and leans on partners
  • Self-serve export excludes documents and invoices and is capped at one backup per day
  • Mobile apps are poorly rated (Google Play ~2.9/5) and described as glitchy
  • Users report steady annual price increases; e-signature, intake/CRM, and texting are gated behind Pro/Advanced
  • SOC 2 Type 2 is attested via the 8am trust center (trust.8am.com) on request rather than stated on the public marketing security page

CosmoLex

Strengths

  • Native trust (IOLTA) plus full double-entry business accounting built in — no separate QuickBooks needed
  • Three-way trust reconciliation, audit trails, and 100+ reports support compliance and financial visibility
  • Genuine all-in-one: matters, time/billing, accounting, documents, and calendaring in one system
  • US-based support praised in reviews; free unlimited support and a free accountant/bookkeeper login
  • SOC 2 attestation (Type 2 per vendor's security page; a 2026 vendor blog cites Type 1 completed with Type 2 in progress), 256-bit SSL in transit, encryption at rest, 2FA, US data centers, automatic backups
  • Consistently high ratings (Capterra 4.6 across 340+ reviews; G2 4.2)

Cautions to validate

  • Base plan per-user pricing is not published on the vendor site — requires sales contact or trial
  • CRM, Websites, and secure file sharing/e-signature (LexShare/LexSign) are paid add-ons on top of the core subscription
  • No native court-rules or rules-based deadline engine documented; calendaring is manual plus sync
  • Mobile app is limited — reviewers report no trust balance, invoicing, payments, or hard-cost entry
  • Reviewers cite billing complexity (recurring billing, payment application) and limited bank-feed/data upload
  • QuickBooks Online sync is one-way and only on Standard/Elite tiers
05

Run identical legal demo scenarios

Use the same synthetic records, roles and required outputs with both vendors before deciding.

  1. New matter intake and conflict check: Submit a realistic web inquiry, detect a possible conflict, capture the resolution, send an engagement letter and open the matter without re-keying contact data.
  2. Court deadline change: Move a court date and show how dependent deadlines, assignments, notifications and the audit trail change. Confirm that rules-based calculations are jurisdiction-appropriate.
  3. Time to invoice and payment: Enter time from desktop and mobile, apply a rate arrangement, review a pre-bill, issue an invoice and record an online payment.
  4. Trust and IOLTA reconciliation: Receive a retainer, allocate funds by client and matter, apply earned funds, reconcile the account and produce the supporting ledger without commingling.
  5. Complete export: Export contacts, matters, custom fields, notes, communications, documents, calendar data, time, invoices, payments and trust ledgers in documented, usable formats.
