TL;DR

• Pick CosmoLex if your firm needs built-in trust and business accounting with a full general ledger, and you’re comfortable paying a higher per-seat price for that integrated back-office.
• Pick MyCase if you’re a solo or small firm that wants the lowest entry price, AI-assisted features (8am IQ), and is willing to use external accounting software.
• Core tradeoff: CosmoLex’s Standard tier ($109/seat annual) is more than 2.5x the price of MyCase Basic ($39/seat annual), but CosmoLex includes accounting functionality that MyCase leaves to third parties.

Pricing

Lowest tier: MyCase Basic starts at $39/seat/month billed annually ($49 month-to-month) and includes case management, client portal, time tracking, billing, online payments, and unlimited document storage. CosmoLex Standard starts at $109/seat/month billed annually with time/expense/billing plus trust and business accounting, financial reporting, and a custom dashboard. CosmoLex does not list a month-to-month rate on its current pricing page.

Middle tier: MyCase Pro is $89/seat/month annual ($99 monthly) and adds 8am IQ Legal AI, custom fields, unlimited 2-way texting, client intake, unlimited eSignature, and Google/Outlook integrations. CosmoLex Elite is $129/seat/month annual and adds matter workflows, matter templates, and matter budgets.

Highest tier: MyCase Advanced is $109/seat/month annual ($119 monthly) and adds MyCase Drive, full-text search, 8am IQ case assistant, advanced document automation, split billing, and an open API. CosmoLex’s top tier, Elite + Website, bundles Elite with a customized firm website, SEO content, and hosting; per-seat pricing for this bundle is not published on the pricing page.

Neither vendor gates pricing, both publish rates publicly.

When to pick CosmoLex

CosmoLex is the stronger fit for firms that want practice management and accounting in one system. Its Standard tier explicitly includes trust accounting, business accounting, and financial reporting, capabilities MyCase does not advertise on any tier. This matters for:

• Small-to-mid firms (CosmoLex explicitly targets “mid” while MyCase stops at “small”) that don’t want to run QuickBooks alongside their PM tool.
• Firms where compliance-grade trust accounting is a daily workflow rather than an occasional reconciliation.
• Firms that want matter workflows, templates, and budgets (Elite tier) without stacking on a separate automation product.
• Firms considering the Elite + Website bundle as a consolidated vendor package covering operations and web presence.

When to pick MyCase

MyCase is the stronger fit for solo and small firms prioritizing price and AI-assisted productivity. Specifically:

• Solo practitioners where $39/seat/month annual (vs. $109) materially changes the cost calculation.
• Firms that already run external accounting (QuickBooks, Xero) and don’t need CosmoLex’s built-in ledger.
• Firms that value AI features, MyCase includes 8am IQ Legal AI at the Pro tier and an 8am IQ case assistant at Advanced, which CosmoLex’s published tiers do not mention.
• Firms that need unlimited 2-way client texting and unlimited eSignature, both included at MyCase Pro.
• Firms that want an open API (MyCase Advanced) for custom integrations.

Integrations and ecosystem

Neither vendor’s JSON lists specific integrations, so a direct count isn’t possible from the structured data. From tier descriptions:

• CosmoLex advertises integrations with Outlook, Microsoft 365, and Google Calendar at the Standard tier.
• MyCase advertises Google and Outlook integrations starting at the Pro tier, and exposes an open API at the Advanced tier.

MyCase’s open API at the top tier is a meaningful differentiator for firms that plan custom integrations or data pipelines; CosmoLex’s public pricing page does not highlight an equivalent API tier.

Historical pricing context

CosmoLex has raised prices steadily. Wayback snapshots show an annual rate of $79/seat in early 2022, a “Starter” tier at $85 in mid-2022, a starting price of $89 in August 2023, then Standard at $99 in April 2025, and Standard at $109 currently, roughly a 38% increase in the entry price over four years. The Elite tier held at $129 between April 2025 and the current snapshot.

MyCase pricing history in the JSON is sparser: a single “MyCase” tier at $49 in January 2022 and a “Basic” tier at $39 in March 2022. The current Basic annual rate is still $39, suggesting MyCase has held its entry annual price flat since 2022 even as it expanded into three tiers.

The net picture: CosmoLex has moved upmarket on price while MyCase has preserved its low-end anchor and layered higher tiers ($89 Pro, $109 Advanced) on top.
