Property management is not lease accounting
MRI Software manages properties: tenant portals, rent collection, maintenance requests, investment analysis. ProLease is their lease accounting module, built to serve the property management platform's existing customer base.
The problem: property management and lease accounting are different disciplines with different users, different workflows, and different compliance requirements. Property managers care about occupancy rates and tenant satisfaction. CFOs care about ASC 842 compliance and journal entry accuracy. Building software that serves both audiences means neither gets the full attention they deserve.
Arvexi serves accountants exclusively. Every feature, every AI model, every workflow is designed for lease accounting teams. When we build a lease modification workflow, we're thinking about remeasurement triggers and journal entry impacts, not property management implications.
Legacy architecture limits innovation
ProLease has on-premises origins. MRI has been migrating the platform to the cloud, but legacy architecture leaves fingerprints everywhere: batch processing instead of real-time calculations, scheduled exports instead of live APIs, desktop-oriented workflows in browser wrappers.
Arvexi was built cloud-native in 2025. Real-time calculations update when inputs change. APIs expose every feature programmatically. AI processes documents asynchronously and notifies you when extraction is complete. The architecture assumes modern infrastructure, modern AI, and modern workflows.
You can migrate a legacy application to the cloud. You can't easily migrate a legacy architecture to a modern one. The constraints of the original design persist through every cloud migration.
Your lease accounting shouldn't depend on property management
When you use ProLease, you're a customer of MRI Software, a property management technology company. Your lease accounting needs are one input among many that drive MRI's product roadmap, alongside property management features, investment management tools, and facilities platforms.
At Arvexi, lease accounting customers are the only customers. Product direction, engineering priorities, and support resources are entirely dedicated to making lease accounting better. When FASB issues guidance or GASB releases a new standard, our entire team responds because there's nothing else competing for attention.
Independence matters when your compliance depends on it.
