What's New in Kos Manager
1.6.0
September 8, 2026
Version 1.6.0 is our biggest update yet: a page of their own for tenants, self-service payment, a tenant balance, and a complete money journal. TENANTS GET THEIR OWN PAGE Send the link from the room. It holds their bill, invoices, receipts, the contract, and a form for sending transfer proof - for the whole stay. THEY SEND PROOF, YOU CONFIRM IN ONE TAP Transfers arrive in an inbox with the photo and the amount. One tap records the money against the month it is owed on. OVERPAYMENT BECOMES A BALANCE Money beyond the bill sits as the tenant's balance and pays each month as it falls due. The room shows what is left; Finance shows how many months it covers. A balance can also be reduced when a transfer bounces. EVERY RUPIAH IN AND OUT Money movements lists each receipt, refund and expense with the account it left and the one it reached - including your own deposits and withdrawals. Pick a period and export it to spreadsheet or PDF. SIGN THE CONTRACT ON A PHONE One page, three steps, the signature drawn on screen. You get a notification the moment it is signed, with the PDF on the room. CHECK IN FROM THE LINK The tenant fills in their own details and uploads their ID. You review it and accept, and nothing has to be typed twice. A MOVE CARRIES EVERYTHING WITH IT Transfer a tenant to another room and their payments, balance, contract and their own page go too. Their old link still works. SEND A RECEIPT IN ONE TAP After you record a payment, one tap sends the PDF receipt over WhatsApp or LINE in the tenant's language. A BILL THAT ADDS UP Paying off the rest lists rent, the deposit and today's late fee separately, and they add up to the total. Changing a room's rent updates its unpaid bills at once. Also: the balance sheet and account balances now always agree, account balances count deposits correctly, and many smaller fixes from check-in to checkout.
