01How it works

Plan together → it lands in the ledger → settle

No spreadsheets, and no “who paid for what?” at the airport. One app from the first idea to the final transfer — and the maths is shown in full below, not asserted.

The short version

Because the trip knows who its members are, every cost added to it can be split without anyone doing arithmetic.

  1. Step 1

    Plan together

    Create a trip, invite your crew with a code, and let AI draft the itinerary, stays and travel for any destination.

  2. Step 2

    Book it — it lands in Money

    Tap “Book this” on a flight or stay, or add an expense. Every cost flows into one shared ledger automatically.

  3. Step 3

    Settle up

    TripSync tracks the budget and shows exactly who owes who — in the fewest payments. Square up in a tap.

05The route

Idea to settled,
in four stops.

No step here is “export to a spreadsheet”, and no step is “work out what everyone owes”. That is the difference.

Stop 1

Create & invite

Start a trip — destination, dates, budget — and share the join code.

The crew is fixed from here, so every later split knows who could be in it.

Stop 2

Plan together

Generate the itinerary, compare travel, shortlist stays. Everyone edits one plan.

Pick a flight or a villa as a group and it locks into the timeline.

Stop 3

Spend & split

Bookings land in the ledger automatically. Cash costs take ten seconds to add.

Choose who shared it. Balances recompute for the whole group instantly.

Stop 4

Settle & recap

The debt graph collapses to the minimum transfers. Mark them paid, and you’re done.

Then the recap: the route, the days, the spend, the album — in one card.

04The maths

Nobody chases anybody.
Ever.

Here is one week in Goa — four people, six shared costs, ₹24,000 — settled end to end. No hand-waving: every number below is derived from the one above it.

An illustrative trip, not a customer’s. TripSync records and calculates — it never moves real money.

01

What the group actually spent

Every cost records who paid it — which is not the same question as who it was for. Conflating those two is exactly why the spreadsheet always ends up wrong.

  • Beach villa · 3 nightspaid by Rohan₹8,550
  • Sunset cruise · 4 ticketspaid by Diya₹5,000
  • Dinner at Thalassapaid by Aarav₹3,150
  • Airport cabs · both wayspaid by Sneha₹2,550
  • Scooter rental + fuelpaid by Aarav₹2,400
  • Groceries & breakfastspaid by Diya₹2,350
₹24,000 ÷ 4 travellers₹6,000 each
02

What that makes each person’s net

Net = what you paid − the ₹6,000 you owed. The four nets always sum to exactly zero. If they don’t, the ledger is wrong, and the app tells you.

  • Aaravowes ₹450
  • Diyais owed ₹1,350
  • Rohanis owed ₹2,550
  • Snehaowes ₹3,450

▲ owed by the group · ▼ owes the group · sums to ₹0

03

The fewest payments that clear it

Biggest debtor pays the biggest creditor; repeat until everyone is at zero. Four people with a tangle of debts settle in three transfers — not the six separate “can you send me…” messages that paying each other back one bill at a time produces.

  • SnehapaysRohan₹2,550
  • SnehapaysDiya₹900
  • AaravpaysDiya₹450

Check it: Sneha sends ₹3,450, Aarav sends ₹450, Rohan receives ₹2,550, Diya receives ₹1,350. Everyone lands on zero.
