Designed to reduce your workload, not add to it
Single-page billing — see all rooms at once. Fill in missing meters right there. Click "Generate All Bills" — PDFs and pay links ready instantly, share via LINE. It also pro-rates rent for mid-month move-ins, rolls unpaid balances into the next bill automatically, and supports both metered and flat-rate water.
See every room's status at a glance: Available / Occupied / Overdue / Maintenance. Click any room for details.
Send a bill link via LINE or SMS. Tenants open it, scan PromptPay QR, upload slip — you're notified instantly. No more chasing. Prefer paper? Print invoices the traditional way — both modes work.
Enter water-electricity meters for multiple rooms using Tab key. Abnormal usage alerts included.
Add, checkout, upload contracts and ID cards. Search by name, phone, or room number. Migrate tenants and rooms from your existing Excel with CSV Import — no retyping room-by-room.
Print A4 paper invoices and receipts to hand out the traditional way. Professional format for tenants who don't use smartphones.
Manage multiple buildings and floors within one dormitory — available on every plan. Multi-property (separate locations) requires Pro or above.
Keep the meters you already have — dial or digital. Walk the property, type each room's water and electricity into your phone, and every room autosaves. Then bill straight from it. No double-entry into Excel, no expensive digital-meter or automatic-reading hardware to install.
Phone for daily check-ins, tablet for billing day, laptop in the office — same data, same look, no app to install.
