Overview
Manajemen Kos is an EWWD product demo for boarding-house and kos management. It connects a public marketing and booking site with an operations dashboard and a tenant self-service portal. The reference implementation is deployed at manajemenkos.ewwdevs.com and supports property-scoped data, roles, branding, Indonesian payment gateways, and WhatsApp notifications.
Business Problem
Kos operations are often split across spreadsheets, WhatsApp admin chats, paper contracts, and informal payment notes. Prospects cannot see live room availability. Owners struggle to generate monthly invoices on time. Overdue follow-up is manual. Tenants lack a trusted place to view bills, pay online, or report repairs. Multi-property operators also need branded sites and staff access limited by location.
