Billy: split costs in chat

Five of you spent a weekend away, and now nobody remembers who paid for the rental and who paid for dinner? Billy logs shared expenses right inside a Telegram chat so you do not argue over a calculator later. 🐨

Billy is a mini app: add it to a group chat and everyone can enter expenses straight away. Friends do not have to install anything extra.

Fair splits without a spreadsheet

Billy is built for trips with friends and any situation where costs get shared: a group dinner, a cabin rental, a gift for a coworker. It also fits couples who keep a joint budget.

You enter expenses the familiar way through the app interface. The whole history is saved, so totals are there whenever you want to look.

A chat that stays clean

One handy detail: the bot deletes its own service messages. Your group chat does not turn into a feed of notifications about every coffee added.

• No installs: just add the bot to the chat.
• History is kept: records survive between trips.
• Help on hand: /help covers the basics and /start opens the bot.
• Support: the project has a separate support bot for questions.

Set up in five minutes

1. Create a group chat with the people you share costs with, or use an existing one.
2. Add Billy to the chat and launch the mini app.
3. Log expenses right away while the receipt is in your hand: amount, who paid, for whom.
4. Check in at the end of the trip. The summary shows who owes whom and how much.

Keeping friendships intact

An expense tracker only helps, and the agreements stay with people. Before a trip, talk through a few simple rules:

• Who splits shared costs equally and who pays only for their own.
• Which currency counts as the main one abroad.
• When to settle up: every evening or at the end of the trip.
• Who may add and edit entries.

Logging costs on the day of the purchase keeps the numbers accurate. A week later nobody remembers what lunch at the station cost.

Small habits that save nerves

Keep photos of receipts in the chat next to the expense entry. If someone doubts an amount, the proof is a second away.

Enter only your own payments and do not edit other people's entries without agreement. If you made a mistake, add a correction and say so in the chat.

For long trips, start a separate group for each one. Totals then stay apart from past journeys, and counting costs per trip is easier. ✈️

What the bot says about itself

Billy's description calls it more convenient than a well known bill splitting app. That is the authors' own claim, so try it and compare with whatever you use now.

Full terms, limits and any paid features are shown inside the mini app. If something is unclear, write to support. 💬
