How Amsio works
Amsio keeps track of shared expenses for a group, in the chat apps you already use. Everyone sees the same group; balances always add up.

How splits work
Every expense is shared by the people you pick. Choose how when you add it, and Amsio works out each person’s share so that the shares always add up to the total.
- EquallyEveryone you pick pays the same amount.Dinner $120 · Srivatsan, Maya, John: $40, $40, $40
- ExactYou enter what each person owes. The amounts must add up to the total.Dinner $120 · $50, $40, $30
- PercentYou enter each person’s percentage. They must add up to 100%.Dinner $120 · 50%, 30%, 20%: $60, $36, $24
- SharesYou enter shares, for example 2 for a couple and 1 for one person. Costs follow the shares.Dinner $120 · 2, 1, 1 shares: $60, $30, $30
Cents, receipts and refunds
- Leftover cents. If a total doesn’t divide evenly, the extra cents go one at a time to the people with the biggest fractions. If it’s a tie, whoever joined the ledger first gets it. The same answer every time.
- Scanned receipts. Each item goes to the people who had it. Tax and tip are shared in proportion to what each person ordered (or equally, if you choose).
- Refunds. Money that came back is shared back to the people you pick, the same way.
- Changing a split. Open the expense and choose Request correction. The original stays in its history.
- Who does the maths. Amsio does, on the server. Your screen only shows the result.
Things you can send
The same words work in WhatsApp and Telegram. Anything else is read as an expense, like “taxi 30” or “Sam paid 120 for dinner, split equally”. Nothing is saved until you confirm.
In a Telegram group
Add the bot to your group. It only reads commands (like /summary), messages that mention it, and replies to it. Balances and sign-in links always go to your private chat.
In a WhatsApp group
Amsio can’t sit inside a WhatsApp group yet. Post the invite link in your group; each person taps it to join, then chats with Amsio one-to-one using the words above. Telegram groups work as described above.
