You manage rental rooms but spend 2-3 days each month closing utility meters and calculating bills for each room?
Complete Rental Property Management System is a rental property management solution on Excel — manage from Contracts → Utilities → Payments → Receivables in a single file, with auto-generated Zalo messages.
LANDLORD PAIN POINTS THIS TOOL SOLVES

- Easy to mix up old/new meter readings when managing multiple rooms
- Having to text each tenant their bill, often with wrong numbers
- Not knowing which rooms have expiring leases to proactively find new tenants
