TL;DR

• Pick MyCase if you’re a solo or small firm that wants an all-in-one cloud platform with a modern client portal, AI features, and transparent per-seat pricing starting at $39/seat/month (annual).
• Pick Tabs3 if you’re a small-to-mid firm that prioritizes robust billing, trust accounting, and full general ledger capabilities, or if you need an on-premise deployment option.
• Core tradeoff: MyCase bundles practice management + billing in one SaaS price; Tabs3 separates billing/financials from matter management (PracticeMaster is a paid add-on) but offers deeper accounting depth.

Pricing

MyCase publishes three tiers on a per-seat basis:

• Basic: $49/month (or $39/month billed annually), case management, client portal, time and billing, online payments, unlimited document storage.
• Pro: $99/month ($89 annual), adds 8am IQ Legal AI, custom fields, unlimited 2-way texting, eSignature, and intake management.
• Advanced: $119/month ($109 annual), adds MyCase Drive, full-text search, 8am IQ case assistant, advanced document automation, split billing, and open API access.

Tabs3 structures pricing around deployment model, with PracticeMaster (matter management) as a separate add-on:

• OnSite Subscription: $69/month/seat, Tabs3 Billing, Financials, and Connect for on-premise deployment.
• Tabs3 Cloud Subscription: $89/month/seat, same core plus Tabs3Pay and cloud hosting.
• PracticeMaster add-on: $32/month (OnSite) or $35/month (Cloud) per seat, adds matter management, document automation, calendars, and conflict checks.

Neither vendor gates pricing. A fully loaded Tabs3 Cloud + PracticeMaster seat runs $124/month, which sits between MyCase Pro ($99) and Advanced ($119) but separates billing/accounting depth from matter management.

When to pick MyCase

MyCase is a fit for solo practitioners and small firms that want one login, one bill, and cloud-first access. The Basic tier at $39/seat (annual) undercuts Tabs3’s entry point, and it includes a client portal, online payments, and unlimited document storage out of the box without add-ons. Firms that want AI-assisted drafting and case summaries get 8am IQ at the Pro tier ($89 annual). MyCase’s single-bundle model also means firms don’t need to reason about which modules to license, matter management, billing, time tracking, and the client portal come together. For a two-to-five attorney firm that values simplicity and modern UX over accounting depth, MyCase aligns with the target profile.

When to pick Tabs3

Tabs3 is a fit for small-to-mid firms that treat billing and trust accounting as the core system of record. Founded in 1979, Tabs3 has a long track record in law firm financials and offers a full general ledger via Tabs3 Financials, functionality that most all-in-one practice platforms delegate to QuickBooks. Firms that want to stay on-premise have a first-class option at $69/seat/month, which MyCase does not offer (it is cloud-only). Tabs3 also allows firms to license just billing and financials without paying for matter management, which can be cheaper for firms that already have a case management tool or don’t need one. The modular structure is an advantage for firms with specific workflow requirements.

Integrations and ecosystem

Neither vendor’s JSON currently lists specific integration partners, so a detailed comparison isn’t possible from the structured data. That said, MyCase’s Pro tier explicitly advertises “Integrations: Google, Outlook, + more” and the Advanced tier adds an Open API, suggesting an integrations story aimed at extending the platform. Tabs3’s pricing page emphasizes its own suite (Tabs3 Billing, Tabs3 Financials, Tabs3Pay, Tabs3 Connect, PracticeMaster) more than third-party connectors, consistent with its historical posture as a self-contained stack. Buyers who need specific integrations should verify directly with each vendor.

Historical pricing context

MyCase has limited but informative pricing history. Wayback snapshots show a single “MyCase” tier at $49/month in January 2022, then a “Basic” tier at $39/month by March 2022, consistent with a repackaging into multiple tiers rather than a straight price hike. Today’s Basic tier is $49 monthly or $39 annual, meaning the annual rate has held at $39 for roughly four years while the monthly rate returned to $49. Tabs3 has no pricing history captured in the dataset, so trajectory can’t be established from the JSON.
