Overview

CosmoLex keeps emails, tasks, events, documents, billable items, and transactions attached to client matters, which gives a firm a shared record of work and finances instead of scattering them across separate tools. Client intake forms and a secure client portal are included on every plan. Multi-user access, role-based permissions, custom workflows, and real-time collaboration make it suitable for teams, not just solo practitioners.

The platform combines trust and business accounting with time tracking, billing, payments, email and document management, tasks, and calendaring. That breadth can simplify a firm's software stack, but it may be more than a practice seeking only billing or timekeeping needs. CosmoLex is part of ProfitSolv and was developed in 2013.

Key features

Matter-linked work and client collaboration

Connecting communications, documents, work, and transactions to matters helps staff keep client activity and financial records in context. The portal gives clients a secure collaboration channel, while intake forms support the start of a matter. Firms that do not need client-facing collaboration may get less benefit from this integrated approach.

Accounting and compliance

Trust accounting includes three-way reconciliation and detailed audit trails, while the system also handles business accounting, billing, and payments. More than 100 real-time reports provide financial visibility. This is a strong fit for firms that want trust and operating finances alongside matter management; firms with a separate accounting workflow may find the combined scope less useful.

Integrations, security, and support

Integrations include Gmail, Outlook, Apple Mail, Yahoo Mail, Microsoft 365, Google and Office 365 calendars, Dropbox, Box, Google Drive, OneDrive, NetDocuments, LawPay, and Zapier. Zapier connects CosmoLex with more than 4,000 applications. Security includes SOC 2 Type 2 certification, encryption in transit and at rest, SMS two-factor authentication, and user-level roles and access privileges. Data is backed up every few hours with encrypted redundant copies and stored in U.S.-based data centers.

All plans include onboarding, a knowledge base, group training, and support by phone, chat, or email. A login allows one web session and one mobile-app session at a time, a practical constraint for users who need simultaneous sessions on multiple devices of the same type.

Pricing

CosmoLex is subscription-based, priced per user per month, with no free plan. All three published plans are billed monthly:

Launch — 49.00 USD per month per user: Time tracking and invoicing, online payments, trust accounting and ledgers, compliance reporting, and bank reconciliation. It is the entry point for firms that need core time, billing, and trust functions, but it omits the general ledger, payables, and bank feeds included in higher tiers.
Core — 99.00 USD per month per user: Adds flexible billing and retainers, general ledger and payables, and bank feeds to the Launch features. It suits firms that want broader business accounting and billing flexibility, though it does not include Pro's advanced compliance reporting.
Pro — 129.00 USD per month per user: Includes Core's listed features and advanced compliance reporting. It is the fit for firms that need that added reporting depth; otherwise, the $30 monthly per-user premium over Core may be hard to justify.

The 10-day trial requires no credit card and otherwise has the same practice-management functionality as a paid subscription. It permits only one bank-feed connection and excludes CosmoLex CRM and the LexShare and LexSign add-ons. Those exclusions matter if evaluating the add-ons is part of the buying decision.

Platforms

CosmoLex runs on the web and has native apps for Android and iOS. A browser can also access the service from an internet-connected mobile device. The mobile apps are included with a subscription or trial.

Who it's for

CosmoLex is best for small and mid-sized law firms that want matter management, client collaboration, trust compliance, and business accounting in one platform. Its per-user monthly pricing is less attractive for firms that need only a narrow billing tool, and its session limit may frustrate teams that rely on multiple concurrent web or mobile sessions per login.

Pros and cons

Pro: Matter-linked records connect client work and financial activity, reducing fragmentation across practice and accounting tasks.
Pro: Every plan includes a secure client portal, intake forms, onboarding, training, and support across phone, chat, and email.
Pro: Three-way trust reconciliation, audit trails, and more than 100 real-time reports serve firms that need financial oversight and compliance visibility.
Con: Pricing is per user, so costs rise with team size, and the lower Launch tier lacks general ledger, payables, and bank feeds.
Con: The trial lasts only 10 days, allows one bank-feed connection, and excludes CRM and LexShare/LexSign.
Con: One web session and one mobile-app session per login limit concurrent use on each platform type.

Alternatives

For narrower needs, CosmoLex also overlaps with Legal CRM Software, Legal Accounting Software, Legal Billing Software, Legal Practice Management Software, Legal Client Portal Software, and Legal Payments Software.

Lawmatics is a paid alternative with a free trial and an Essential plan featuring 500 contacts, intake, lead management, calendaring, forms, e-signature, SMS, and task management; consider it when lead and intake workflows are the priority.
Actionstep offers matter and case management, intake and form management, and document management, with per-user pricing plus implementation fees; consider it when that practice-management scope is the focus.
Referent has a free plan with AI usage included and a free trial; consider it if a free starting option matters most.
Nexl CRM uses custom pricing and offers a personalized demo.
RocketPro Engage has a Standard plan at 297.00 USD per month, billed at $2,844/year, for solo practitioners with unlimited users and automations and email support; its RocketPro AI plan is 497.00 USD per month, billed at $4,764/year. Consider it when those stated solo-practitioner terms suit the need.
CasePeer offers a Basic plan at 79.00 USD per month per user with case and contact management, tasks, a client portal, statute alerts, medical treatment tracking, and unlimited document storage; consider it when those case-oriented tools are a closer match.
Senitix CRM has a free plan for up to two users, 1,000 contacts, 1,000 leads, 250 deals, one pipeline, and 0.5 GB of workspace storage; consider it when those free CRM caps meet the need.
Captorra Intake offers custom pricing, with plans for up to five users or unlimited users.

Verdict

Choose CosmoLex if your small or mid-sized firm wants matter management and trust and business accounting joined with billing, client collaboration, and compliance tools. Its strongest reason to buy is that breadth around matter-linked records; look elsewhere if per-user costs, trial exclusions, or the session limit outweigh the value of an all-in-one legal platform.
