Tenancy Manager can tell us at a glance how much John Smith owes this month. It can send an email rental invoice with just two clicks without even needing to view the actual record. Tenancy Manager can tell you when the gas safety record is due for John Smith's tenancy. All at a quick glance with as few clicks as possible. You probably don't need Tenancy Manager if there's just one John Smith but what if there's 40, 50, 100 tenancies? That's where you need to be able to manage arrears and inspections easily and not be spending all your time trying to remember who owes what and when stuff needs doing.
