Every screen, in the order you'd actually use them.
Every door you hold, let or empty, with rent, occupancy, and eighteen months of leasing history on one screen.
Every tenant, past or present, with their unit, lease dates, and contact details in one list.
Every rent payment, refund and fee in one ledger, reconciled against the bank feed instead of left to memory.
What a tenant reported, what it cost, and who fixed it. Nothing falls out of a text thread and gets forgotten.
Rent reminders, late notices, and lease renewals, written once and sent automatically instead of retyped every time.
Every change to the company, and who made it, in a record that's only ever added to.
