The LeaseWave® Lessee lease accounting software system allows lessees to log onto a website built exclusively for them in order to, among other things, inquire about the state of all their leases. Lessees can ascertain, at both a summary and detail level, the outstanding balances on their lease accounts. Moreover, they can check on outstanding invoices and also assess what payments are coming due in the future. Through the LeaseWave® Lessee lease management system’s lease maturity monitoring functionality, lessees can check when leases are maturing by dynamically determining a range of potential expiry dates.
