Fewest transfers
Four people, four bills. Three transfers and done.
Settle pair by pair and everyone ends up paying several people odd amounts. Chia Hóa Đơn nets the whole group first, so there are as few transfers as possible.
Paying back each bill separately would take 12.
Three steps, one minute
No spreadsheets, no long reminder messages.
Create a group, send the link
Name the group and pick its currency. Drop the link or QR code into your chat — friends tap it and they are in.
Whoever pays, writes it down
Enter the amount, who paid and who it is for. Split equally, by shares, by percentage, by item, or with someone treating.
See who pays whom
The app nets everything out and suggests the fewest transfers. Scan a bank QR to pay; the receiver confirms and it is done.
Everything a group needs to split costs
From the first expense to closing the book, all in one place.
Split it any way
Equally, by exact amounts, by percentage, by shares, by item, or with someone covering part of it.

Everyone pays the same.
Pay by QR
Save a receiving account once. Whoever owes you scans the QR — right amount, right person, no account numbers to ask for.
Add people without an account
Add parents, partners or friends who do not use the app as guests. They can claim their place later.
Updates in real time
When someone adds an expense the whole group sees it. You are notified when it is your turn to pay or receive.
And more
Share a read-only book
Send a link to anyone who will not sign up. They see the book and the balances, and cannot change anything.
Clear statistics
See where the money went: food, transport, stays — who paid most, which day cost most.
Add it to your home screen
It works in the browser. For quicker access, add it to your home screen like an app.
Close the book when you are done
The group owner closes the book to freeze the numbers, so nothing gets edited by mistake after everyone has paid.
Group funds
Keeping a shared fund for a class, club or team?
Group funds are their own area in Chia Hóa Đơn: collect dues in rounds, see right away who still owes, and keep every payment clear for the whole group to see.
Collection rounds with a due date
Set an amount per person and a due date — this Sunday, month end, or any day you pick.
See who still owes, instantly
A paid / unpaid table for every round, no adding up by hand or chasing messages.
Transparent money in and out
Every payment and every fund expense is recorded. Share a public link so the whole group can see the balance, no account needed.
Deputy treasurers help out
The treasurer can add deputies to open rounds and record money too — nobody has to carry it alone.

Common questions
Didn't find your question?
Just try a group. It is free, and you can delete it any time.
Create a group, freeDoes Chia Hóa Đơn cost anything?
No. Creating groups, recording expenses, settling up and sharing a book are all free. A group fund is free too.
Do I need to install an app?
No. Open the website on your phone or computer and start. If you like, add it to your home screen to open it like an app.
Does everyone in the group need an account?
No. People without an account can be added as guests, and anyone who only wants to look can open a shared book link without signing in.
How does it work out who pays whom?
It adds up what each person paid, subtracts each person's share, then pairs those who are short with those who are owed so there are as few transfers as possible.
The bill has many dishes and everyone ordered differently. How is that split?
Choose By item: enter each dish and who had it. Tax, service or a discount on the bill is shared by what each person had.
Can I use it abroad?
Yes. Each group picks one currency when it is created and keeps it, so the numbers never drift.
Who can see my bank account number?
Only people in the group who currently owe you, and whoever opens the shared book link if the owner turned sharing on. Account numbers are encrypted when stored.
How is a group fund different from Shared expenses?
Shared expenses splits an expense among the people who used it. A group fund is different: it collects money into a shared pot in rounds and spends from that pot — nothing is split among members. The treasurer and deputy treasurer keep the books together; it suits a class, a club or a parent group.
Who can see a group fund?
Members of the fund see every entry. If the treasurer turns on the public link, anyone with it can see the balance and who's paid — no account, nothing they can change.
