Why ClearLeaseMath Exists
Property accounting disputes rarely happen because the underlying math is secret—they happen because informal back-of-the-envelope calculations lack transparent methodology. Whether splitting a quarterly municipal water bill across a fourplex or prorating carpet replacement after a 32-month tenancy, handing a tenant or housing court referee a bare dollar figure invites friction.
Every utility on ClearLeaseMath is designed around three accounting principles:
- Full Formula Transparency: Every printout displays the exact statutory or contractual formula, common-area credit, and proration denominator alongside the dollar result.
- Zero Server Data Retention: Unit rosters, property addresses, and invoice figures run entirely in your browser and persist only in your local storage or shareable URL parameters.
- Audit-Ready Formatting: Pressing Print on any calculator strips away web navigation and outputs a structured black-and-white statement ready to attach to a lease or monthly billing packet.
