CoStar Real Estate Manager vs Ledgerage

CoStar Real Estate Manager is a web platform for large-scale and global accounting and real estate teams managing complex portfolios. It provides shared visibility across the lease lifecycle, with accounting workflows that automate classification, measurement, and reporting for ASC 842, IFRS 16, and FRS 102. Teams can handle remeasurements, journal entries, disclosures, roll-forward reports, renewals, critical-date notifications, rent payments, and amendment tracking. Transaction tools support workflow templates, configurable approvals, milestone tracking, deal comparisons, and project kick-offs tied to lease dates. Market and submarket information covers more than 6 million properties for portfolio decisions and research. Managed integrations are listed for SAP, Oracle, Workday, and NetSuite. Access controls include role-based permissions, single sign-on, security profiles, audit trails, and change logs. Pricing is on request and depends on active leases, transactions, or owned or leased locations, depending on the module.

Ledgerage calculates lease present value, right-of-use assets, lease liabilities, amortization schedules, journal entries and disclosures. Its computations cover ASC 842, IFRS 16 and GASB 87. The web calculator is available without an account and is described as free forever, not as a trial. The Free plan includes unlimited single-lease calculations, two saved leases, 25 API computations per month, 10 API requests per minute and MCP access. Its REST API accepts JSON requests and can return calculations, schedules, journal entries or classifications with citations to the applicable standard. The MCP server offers four tools and names Claude Desktop and Claude Code as compatible clients. Pro costs $39 a month, billed month-to-month with no contract. It includes an unlimited lease portfolio, up to 1,000 saved leases, 5,000 API computations per month, 120 API requests per minute, Excel, CSV and PDF exports, lease modifications and remeasurements, and a hosted MCP server. Ledgerage describes its engine as deterministic, with standard citations and schedules that reconcile to zero at term end. It says results depend on user-provided inputs and judgments and are not accounting or legal advice.
