Tenants Pay Online

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.

Batch Meter Recording

Enter water-electricity meters for multiple rooms using Tab key. Abnormal usage alerts included.

Complete Tenant Management

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.

PDF Export + Paper Printing

Print A4 paper invoices and receipts to hand out the traditional way. Professional format for tenants who don't use smartphones.

Multiple Buildings & Floors

Manage multiple buildings and floors within one dormitory — available on every plan. Multi-property (separate locations) requires Pro or above.

★ Read meters with your phone

One phone reads your whole dorm — no new meters to buy

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.

  • Reuse existing meters — ฿0 hardware
  • Walk room-to-room, autosave
  • Bill straight from it
  • From small to 100+ rooms
