Kos Manager: Rental App

Kos Manager keeps the books for a boarding house.

Rooms, tenants, rent, deposits, contracts, expenses. One app, on your phone, instead of a notebook and three WhatsApp threads.

WHAT IT DOES

Rooms and tenants

See every room at a glance: who is in it, what they owe, when they came in. Up to four people per room, each with their own details, one of them marked as the one who pays.

Rent that keeps its own diary

Set the day rent falls due and the app tracks it. Overdue rooms turn red. Reminders go out over WhatsApp or LINE, in the tenant's language, with the amount and the bank details already filled in. You approve the message before it sends.

Money you can check

Every payment says which account it landed in — cash, or any of your banks. Each account carries a running balance. The balance sheet shows what you own and what you owe, and reconciles the accounts against the books, so "the app says this, my bank says that" is a question with an answer.

Trace any figure

A statement of every payment, expense and transfer: date and time, what it was, amount, debit or credit, which account. Filter by week, month, year or your own dates. Search by tenant, room or note. Export to PDF or a spreadsheet your accountant can work in.

Let tenants fill in their own details

Send a link. The tenant types their name, phone, ID number and emergency contact, and photographs their ID, before they move in. You read what came back and accept it — check-in opens already filled in, ID photo included. If something is wrong, send it back with a note. (Professional plan.)

Contracts

Write your own template once, or use the ones included. Send it for signing and the tenant signs on their phone. The signed PDF is stored against the room.

Reports

Income, expenses, profit, occupancy. By month, by year, by house. Export to PDF or Excel.

Also in the app

Deposits tracked separately from rent, because a deposit is money you hold, not money you earned. Reserve a room for someone arriving later. Maintenance jobs with photos and costs. Expenses per house or per room. Works in English, Indonesian and Chinese. Rupiah, or your own currency.

FREE AND PAID

Free covers one house and three rooms. Starter and Professional raise the limits and unlock Excel export, reminders, digital contracts, and self check-in. No advertising, ever.
