Why teams switch from CoStar to Arvexi
CoStar is a real estate data company that acquired its way into lease accounting. Arvexi is purpose-built for lease accounting. It's not a feature on someone else's platform.

| AI Document Extraction | AI reads any lease PDF with confidence scoring | Basic extraction through acquired Visual Lease technology |
| Multi-Standard Support | ASC 842, IFRS 16, GASB 87, GASB 96, FRS 102 simultaneously | ASC 842 and IFRS 16. Limited government support |
| Auditor Portal | Dedicated read-only auditor portal with independent access | No dedicated auditor portal |
| Implementation Time | Days. Self-service setup with AI extraction | Months. Enterprise sales cycle with professional services |
| Core Business | 100% focused on lease accounting and compliance | Real estate analytics. Lease accounting is one product among many |
| AI Agents | Autonomous AI agent with 38+ accounting tools | No AI agent capabilities |
| API-First Architecture | Full RESTful API for programmatic access | Limited integration options |
| Pricing Model | Portfolio-based, transparent pricing | Enterprise pricing, opaque, often bundled with CoStar Suite |
A data company, not an accounting company
CoStar is the dominant force in commercial real estate data. They know market rents, building specs, and tenant information better than anyone. In 2024, they acquired Visual Lease to add lease accounting to their platform.
But knowing real estate data and building accounting software are fundamentally different capabilities. Lease accounting requires deep expertise in ASC 842, IFRS 16, GASB standards, journal entry generation, amortization calculations, and audit workflows. These are not problems you solve by bolting lease accounting onto a data platform.
At Arvexi, lease accounting is the entire product. Every engineer, every AI model, every feature decision is about making lease accounting better. CoStar's lease accounting team competes for resources with their analytics, market data, and listing businesses.
Acquisition stitching is not integration
When CoStar acquired Visual Lease, they inherited a pre-AI lease accounting platform and the challenge of integrating it into their existing product suite. That integration takes years: different databases, different user interfaces, different authentication systems, different development teams.
Arvexi is a single platform built as one system from day one. Document Intelligence feeds directly into Lease Accounting. The AI agent works across every module. Data flows without integration middleware, without ETL pipelines, without reconciliation between acquired systems.
The difference between "acquired and integrated" and "built as one" shows up in every workflow: faster implementation, fewer bugs, simpler administration, and a consistent user experience.
Your lease accounting platform should be obsessed with lease accounting
When you call CoStar support, you're talking to a company that serves real estate brokers, property managers, lenders, and investors. Lease accounting is one product line among many. Feature requests compete with analytics dashboards, market data feeds, and listing services.
When you contact Arvexi, you're talking to a team where lease accounting is the only thing. Every customer conversation, every feature request, every AI improvement goes directly into making lease accounting better. That singular focus translates to faster innovation, deeper domain expertise, and a product roadmap driven entirely by accounting teams.
