By the MahasDev team 
Kelola Kos is ready to download. Search for “Kekos” on the App Store or Google Play, install it, and start right away. No sign-up needed.
Who is it for?
Owners of boarding houses (kos), rentals, and small rental homes who have been keeping records in a notebook or WhatsApp chats. The problems are usually the same:
- Forgetting who has paid and who hasn’t.
- Working out each room’s electricity and water takes time.
- Money in and money out get mixed up, so you never know what’s left at the end of the month.
Kelola Kos is built for exactly those three things.
What it helps with
- Bills are created automatically on every due date. Just check: paid, unpaid, or overdue.
- Electricity and water meters. Type this month’s reading; the cost is calculated and added to the bill.
- Invoices and reminders via WhatsApp. A neat PDF invoice and a pre-filled reminder, ready to send.
- Cash book. Record money in and out, with receipt photos. See the monthly summary at a glance.
- Simple reports. Income, billing, and how many rooms are occupied.
Start in 3 steps
- Download Kekos from the App Store or Google Play.
- Enter your kos name and list your rooms.
- Add your tenants. Next month’s bills are created for you.
Free or paid?
The Free plan is enough to record everything: no account, no internet, up to 10 rooms. Your data stays on your phone only.
If you need more, there are subscription plans:
- Starter — cloud backup (safe when you switch phones) and the tenant portal: tenants open their bills with a 6-character code, no app install, and upload their own transfer receipts.
- PRO — unlimited rooms, more than one property, and accounts for your caretaker.
No ads. We never ask for tenants’ ID card photos or bank account numbers.
