Stress-Free Percentage Rent Calculations and Collections
BasePlus automates the percentage rent administration process by seamlessly tracking sales, calculating rent, and depositing payments—eliminating manual reporting and ensuring transparency for landlords and tenants.
An Automated Solution Simplifying Percentage Rent
BasePlus is a venture by Graffito SP, created to help our landlord clients, and others like them, simplify and streamline the rent collection and reporting process, particularly when percentage rent is involved. We know firsthand that percentage rent leases can be an administrative pain for both landlords and tenants.
With years of experience in the retail leasing world, we’ve seen the frustrations that come with tracking sales, calculating rent, and ensuring payments are accurate and on time. The process is often messy, with manual reports, endless emails, and unnecessary disputes that create friction instead of partnership.
That’s why we created BasePlus. It takes the hassle out of percentage rent by automating the entire process. It connects directly to tenants’ point-of-sale and accounting systems, tracks real-time sales, calculates rent based on lease terms, and deposits payments straight to the landlord—all with full transparency.
No more chasing reports, no more miscalculations — just a simple, efficient system that works for everyone.
