Keyloo is property management software that centralizes rental operations into one platform, streamlining listings, contracts, payments, and tenant communication. As a progressive web app, it works across devices without installation and offers offline functionality. Automated rent reminders notify tenants via push notifications and email, while electronic contract signing allows online lease execution with automatic document archiving. A tax calculator computes rental income tax based on revenue received. Tenants access a portal to view payment schedules, lease agreements, and submit maintenance requests with photos. QR code payment processing enables direct bank transfers without fees. A timeline tracks deadlines like rent due dates, tax payments, and lease expirations. Guided workflows ensure legal compliance for lease processes, and landlords can manage multiple properties or switch contexts between owning and renting within a single account.
