Shared expenses for any group

Shared costs for any group — a trip abroad, a barkada, a household or a class — settled in the fewest payments, in any currency, even when someone pays for others.

Whoever booked the hotel or paid for dinner ends up keeping the tally in a notebook or the group chat, then chasing everyone for weeks. A trip abroad mixes yen and pesos, children pay for their parents, and before long nobody is sure who still owes whom.

Everyone logs what they paid, in whatever currency they paid it, and Tarashare converts it at that day's rate and puts each share on the right person — including whoever is covering it. Settling up takes the fewest transfers possible, each with that person's GCash or Maya QR one tap away. The organiser pays for Pro; everyone they add uses it free, without even needing an account.

What it does

The parts that matter to the owner

01

Someone can pay for others

Say once who covers whom — Ana covers Mom, Ana and Ben split Dad — and every dinner, taxi and ticket lands on the right person, with everyone able to see who is covering what.

02

Spend in yen, see it in pesos

Log each expense in the currency it was paid in. Tarashare converts it at that day's market rate, or at the rate the card actually charged.

03

Two taps and everyone is square

The smallest set of payments that clears the whole group, each person's GCash or Maya QR one tap away, and marking one paid updates every balance.

04

Made for every kind of group

Trips, barkada nights, school projects, households and events — each with its own categories, and dates only where a group actually has them.

05

Dues, reminders and reports

Collect class dues or a household's bills into the group's fund, send a weekly reminder of what each person owes, and print the report or export it to Excel.

06

Keeps working without a signal

Expenses logged on a mountain road or a plane are kept on the phone and sync when the connection is back.

What is new in Tarashare

New

An itinerary to show at immigration

Print a travel itinerary with the travellers, every flight and hotel, and the plan day by day — no amounts, just what an immigration officer asks to see.

Reminders that do the chasing

Organisers can switch on a weekly email of what each member owes and a reminder before a collection falls due, and rent or dues can repeat on their own.

Reports, budgets and spending charts

Set a budget for each category, watch spending against it, and print the group's report or export it to Excel.

Screens

A look inside

Tarashare began as a tool for the founder’s own family trip — eleven people, a foreign currency, and children paying for their parents. It opened to everyone in October 2026, first for trips and then for every kind of group.

Only the organiser of a group pays, and only if they want Pro. Everyone else is added by name and can log expenses and payments without signing up, which is what gets a group of cousins or classmates to actually use it. If Pro ends, nothing is lost: the group becomes read-only, and payments can still be recorded until everyone is square.

A group’s money is its own. Each group is walled off from every other, and the tests check every route a stranger could try. The console we run the service from shows accounts and plans — never a group’s name or what it spent.

The screens shown here are from tarashare.app’s public pages; the people and amounts in them are examples.
