The problem it solves
No more piecing things together from scattered notes.
Plenty of owners still track rooms, due dates, transfer receipts, meter readings, and tenant complaints across chat threads and separate spreadsheets. Kos Manager brings all of it together, so one app tells you how the kos is doing today.
Running the place day to day gets easier
- Check room, tenant, and billing status from a single app.
- Nudge payments that are close to due or already late.
- Take in new tenants through a check-in form they fill in themselves, digital contract included.
- Log operating costs so the monthly report stays tidy.
- Export PDF or Excel reports whenever you need them for records and review.
Why Kos Manager
Why do owners pick Kos Manager to run their boarding house?
Five things that set this app apart from the old way of doing it and from tools that only go halfway.
Clear finances, journal included
Every rupiah in and out is recorded with its journal entry, so you can trace where each number came from. Profit, arrears, and operating costs are visible without recalculating anything.
Tenants check themselves in
Share one link and the tenant fills in their own details before moving in. You never retype ID data by hand again.
iOS and Android, not just one
Kos Manager is on both the App Store and Google Play. You use an iPhone, your caretaker uses Android, and the data stays in one place.
Easy to use from day one
No training required. Add a room, enter the tenant, and the invoices and reports follow on their own.
Inside the app
See exactly how the app looks on your phone.
The four screens owners open most every month: the room list, bills, expenses, and financial reports.
Rooms and tenants in one list
Every room at a glance: who is in it, how much is outstanding, and when they moved in. One room can hold several tenants, each with their own record.
Bills and due-date reminders
The dashboard flags bills that are close to due and the ones already late. Reminders go out over WhatsApp or LINE with the amount and account number attached.
Operating costs and electricity meters
Record spending per house or per room, meter readings for electricity and water included, so every extra charge has a clear origin.
Financial reports ready to export
Income, spending, profit, and occupancy by month, by year, or by house. Export to PDF or Excel whenever you need it.
Here is how the digital contract and self check-in flow works, from link to PDF:
1. The tenant fills in the check-in form
Share one link. The prospective tenant enters their name, ID details, and emergency contact from their own phone, and you retype nothing.
2. The contract gets signed on a phone
The tenant reads through the clauses, then signs right on the screen. Nothing to print, nothing to scan.
3. The official contract is saved as a PDF
Once both sides have signed, the contract is valid, stored in the app, and ready to download any time.
How it works

The flow is kept simple so an owner, an admin, or a family member helping out can pick up the system quickly.
