Free Room Rent Bill Maker

Enter the meter readings and the water and electricity are worked out for you. Bills and receipts, on your phone too. No sign-up.

A room rent bill with water and electricity, done in a few minutes

If you still write meter readings in a notebook and work out every room with a calculator at the end of the month, this page makes the monthly bills much quicker. It is free on a phone or a computer, with nothing to install and no spreadsheet to build. It works for dormitories, apartments, mansions, monthly rooms and houses.

A bill a tenant understands shows the property, the room, the tenant, the month, the rent, the previous and current water and electricity readings, the units, the price per unit, the total, the due date and how to pay. A bill made here has all of it, so the tenant sees where every amount comes from and does not need to ask.

How it works

A rent bill in four steps

  1. 1

    Enter the property name, the room number, the tenant and the room rent.

  2. 2

    Add the previous and current electricity and water meter readings — the units and charges are worked out for you — or choose a fixed water charge per room or per person.

  3. 3

    Add other charges such as internet or parking, then your bank account or PromptPay number: the bill gets a QR the tenant scans to pay the exact amount.

  4. 4

    Print or save as PDF, send the bill image on LINE, or copy it as text. Once paid, switch it to a receipt in one tap.

What it works for

  • Rent bills for rooms, dormitories, apartments, condos and houses
  • A rent invoice and a rent receipt from the same details
  • Water and electricity by meter, with a minimum charge, or a fixed water charge
  • A late fee, a discount and any other charges
  • Bills in Thai, or in English for foreign tenants
  • A PromptPay QR with the amount already in it
  • A signature line on the rent receipt, which can be signed on the phone screen
  • Nothing you type is sent to a server or saved; sign up to Track My Room to keep every room

Questions

About making a rent bill

It is completely free, needs no sign-up, and there is no limit on the number of bills.

Nowhere. What you type stays on this page until you close it; only the property name is kept, in the browser on your device. We never receive any of it. To keep unit prices, bank details and every room's meter readings, sign up to Track My Room — your first month is free.

This reading minus the previous reading gives the units used, multiplied by your price per unit. For example, 1,250 last time and 1,370 now is 120 units; at 8 baht a unit that is 960 baht. Water works the same way. If you set a minimum and the result is lower, the minimum is charged.

Yes, and no app is needed. Open this page on your phone and fill it in; when it is done, send the bill image straight to your tenant on LINE.

You do not need a template file: fill it in here and the totals are worked out for you. For a PDF, press Print and choose Save as PDF in the print window, then keep it or send it to your tenant.

Enter the mobile number or ID card number your PromptPay is linked to. The bill shows a QR with the amount already in it; the tenant scans it with any Thai banking app and pays.

Yes. Once the money arrives, switch to Receipt: the same charges, with the date received, how it was paid and a line for your signature.

Yes. Once you switch to Receipt, a Sign on the screen section appears: tap Sign and sign with a finger on your phone, or with a mouse on a computer. Your signature goes on the receipt, ready to send to the tenant on LINE as an image or to save as a PDF. It is not kept: it is gone when you close the page.

The rent invoice goes to the tenant before paying: how much is due this month and how to pay. The rent receipt is made after the money arrives, as proof the tenant has paid. This page makes both from the same charges; switch between them in one tap.

Yes. It works for houses, rooms and condos you let out. Enter the house or project name instead of a dormitory name, then the rent. If the tenant pays the electricity and water companies directly, leave the meter readings empty: the bill shows only the rent and any charges you add.

This tool makes one bill at a time. For many rooms, Track My Room is apartment software that remembers every room's meter readings, makes the invoices and receipts, and sends them to your tenants on LINE. Your first month is free.
