Comparison
LeaseAccelerator (now Costar Real Estate Manager) is an established lease accounting platform used by large enterprises. It does the job. Ledger Layer differs in three material ways that matter in 2026: native AI infrastructure, revenue recognition scope, and self-hosted deployment. If your team is investing in AI, running multi-standard portfolios, or has data sovereignty requirements, these differences are decisive.
Typical enterprise lease SaaS deal: $45K–$250K with a multi-month implementation. Ledger Layer: $499/month, live in minutes.
Ledger Layer is the only accounting infrastructure with a native MCP server — your AI assistant can query, analyse, and act on accounting data with the same role-gated controls as a human user.
| Capability | Ledger Layer | LeaseAccelerator |
|---|---|---|
Architecture era | ✓ AI-native infrastructure — MCP-first, API-first, agent-ready by design | ~ SaaS application — agent access is absent or retrofitted onto a closed data model |
AI agent interface (MCP) | ✓ 75+ schema-validated tools for Claude, GPT, n8n | ✕ No MCP or structured AI interface. No agent-ready API. |
AI-ready data layer | ✓ Structured schema queryable by AI assistants in real time | ✕ Closed data model. No AI agent access to accounting data. |
AI-powered data extraction | ✓ Upload Excel/PDF/CSV — AI extracts lease terms automatically | ✕ Manual data entry or custom CSV import templates. |
IFRS 15 / ASC 606 (revenue) | ✓ Live today — same engine, same infrastructure as lease accounting | ✕ Lease standards only. Revenue requires a separate system. |
Self-hosted deployment | ✓ Docker / Mode 3 — full on-prem, data never leaves your network | ✕ SaaS only. No self-hosted option. |
Approval gate immutability | ✓ DB-enforced. JEs cannot be deleted. Reversal only. | ~ Workflow-dependent. Varies by configuration and admin settings. |
Hash-verified output | ✓ Same inputs → same hash every time. Cryptographic verification. | ~ Standard deterministic logic but output is not hash-verified. |
Deployment modes | ✓ Cloud, hybrid, or fully self-hosted — your choice | ✕ Cloud SaaS only. No hybrid or on-prem option. |
Pricing model | ✓ Entity-based. Transparent. From $49/mo. No implementation fee. | ~ Enterprise pricing. Opaque. Significant implementation project cost. |
Time to first output | ✓ Upload Excel → engine output in minutes. No implementation project. | ~ Implementation project typically runs weeks to months. |
Multi-standard from one record | ✓ IFRS 16 + ASC 842 from same lease data, no duplication | ✓ Supports both standards, but separate configuration per entity. |
ERP / downstream integration | ✓ Structured journal export (CSV, XLSX, JSON) plus MCP and outbound webhooks — drive SAP, Oracle, NetSuite, or any downstream via Alteryx, n8n, Workato, Zapier, or your own middleware | ✓ ERP integrations available. Implementation required. |
Ledger Layer was built for the AI era. A native MCP server with 75+ tools gives your AI agents structured, role-gated access to accounting data. LeaseAccelerator was built before the AI wave — retrofitting AI access onto a closed data model is fundamentally harder than building it in.
Ledger Layer ships IFRS 15 and ASC 606 today — same engine, same audit controls as your lease accounting. LeaseAccelerator is lease-only. If you need revenue recognition, you need a second system, a second vendor, and a second audit trail.
For regulated industries, data sovereignty matters. Ledger Layer runs on your infrastructure via Docker — no data leaves your network. LeaseAccelerator is SaaS-only. If your security team requires on-prem, there is no option.
LeaseAccelerator was built before MCP existed. Ledger Layer was built because it does. Upload your Excel and get engine output in minutes — or connect your agent via MCP in under 5 minutes. Same audit trail, no implementation project.
