CosmoLex vs MerusCase (2026): which should you pick?

Pick CosmoLex if

• Fits if you're a solo or small firm that holds client money in trust
• Works for firms in the US or Canada that want billing and the books in one app

Look elsewhere if

• Tight if you're on Launch, which has no bank reconciliation, LEDES or split billing, intake forms, document assembly or AI
• Pricey if you want the general ledger, bank feeds, calendar sync or the open API, which are Pro only at $129 a user
• Watch out: the CRM, websites, Google Ads management and LexShare and LexSign are paid add-ons, and eSignatures may carry fees
• Not for you if you're in Canada and want card payments on invoices, which the pricing page marks as US only
• Skip it if you want a full trial, as the 10 days come with one bank feed and no CRM, LexShare or LexSign

Pick MerusCase if

• Fits if you want case files, billing and email in one browser-based system
• Works for firms that draft documents in Word

Look elsewhere if

• Skip it if you want to try it before talking to sales, since only a demo is offered
• Not for you if you need a price up front, as none is published
• Watch out: the page read lists no desktop or mobile apps
• Watch out: it carries a 2008-2024 copyright line, so its feature descriptions may be older

CosmoLex

• Launch leaves out bank reconciliation, LEDES billing, intake forms, document assembly and the AI tools, which start on Core at $99 per user / month.
• The general ledger, bank feeds, calendar sync with Outlook and Google, intake automation and the open API are on Pro only.
• The CRM, websites, Google Ads management and LexShare and LexSign are paid add-ons; eSignatures may carry extra fees.
• Card payments on invoices are marked as US only on the pricing page; eCheck is the other option listed.

MerusCase

• No prices are published. The pricing section says custom and tailored, so a quote requires contacting the vendor.
• The product page names browser access and says data is reachable from any device, but it lists no desktop or mobile apps.
• The page read carries a 2008-2024 copyright line, so its feature descriptions may be older than the rest of the site.
• The vendor says its security exceeds HIPAA standards; this is the vendor's claim and was not independently checked.

Trust and business accounting

Trust ledgers with automatic transfers and holds and built-in compliance reports on every plan. Pro adds a general ledger and payables across trust, operating and business accounts.

Time, billing and payments

Matters and client portal

Matter management and a secure client portal on every plan. Core adds per-matter budgets, document editing and assembly, and dashboards.

Intake forms

Logic-based intake forms capture leads and turn them into matters from Core; Pro automates intake workflows. A CRM add-on adds email and text drip campaigns.

AI tools

From Core, AI writes summaries of documents, answers plain-English questions to filter matter data, and drafts client intake forms.

Growth add-ons

Paid extras include a firm website built and hosted by CosmoLex, managed Google Ads campaigns, and LexShare and LexSign for document sharing and eSignatures.

MerusCase

Case files and documents

Contacts, cases, assignments and documents are linked and tagged by type. Case data can be merged into PDF court forms and Word documents, and batch scanning splits uploaded paper into separate documents.

Billing and accounting

A built-in bookkeeping system handles invoices, payments and case-specific ledgers that keep the operating account apart from client accounts. Electronic billing formats include LEDES, ESIS and Chubb.

Time tracking

Time can be tracked with a button click while working, or added to a case ledger afterward with notes.

Calendars, tasks and email

Calendars can be scoped to a person, office or firm, events attach to cases, tasks can be assigned to team members, and email can be synchronized and filed to a case.

Reports

The vendor lists more than 35 built-in reports covering workloads, billing and collection patterns, cash flow and case history.
