Lease-compliant late fee calculation

The platform calculates late fees based on the specific terms of each lease, including grace periods, flat fees, percentage-based fees, and escalating penalties. This ensures every fee is legally defensible and consistent across your portfolio.

Business outcome: Eliminates manual calculation errors and reduces tenant disputes over incorrect fees.

Multi-unit payment tracking dashboard

View all tenant payment statuses in a single dashboard. The system highlights which units are overdue, how many days late each payment is, and what the calculated fee should be based on the lease terms.

Business outcome: Provides a real-time overview of portfolio payment health without digging through spreadsheets.

Audit-ready fee history reports

Every late fee calculation is logged with a timestamp, the lease rule applied, and the resulting amount. These records serve as documentation for tenant communication, legal proceedings, or tax reporting.

Business outcome: Creates a defensible paper trail for every fee charged, reducing legal exposure.

Customizable fee rule engine

Set up different fee structures for different lease types — flat fees, daily accruals, percentage of rent, or tiered penalties. The engine applies the correct rule to each unit automatically.

Business outcome: Enables portfolio-wide fee policy standardization while respecting individual lease variations.

Export-ready data for accounting systems

Export fee calculations and payment records in formats compatible with common accounting and property management software. This bridges the gap between fee calculation and financial record-keeping.

Business outcome: Saves hours of manual data entry by feeding calculated fees directly into your existing workflows.

Free tier with core functionality

The free plan covers basic late fee calculation for a limited number of units, making it accessible for small landlords to test the system before committing to a paid plan.

Business outcome: Lowers the barrier to entry for small operators who need automated fee calculation without upfront investment.
