The organizer should not be the bookkeeper
If someone paid for dinner, they can add dinner. If someone paid for gas, they can add gas. The job does not belong to one person.
The bad version is a Google Sheet, three text threads, and one person guessing who paid for what. TripTally gives the group one place to add expenses while they happen.
Why this search happens
Intent
This search usually comes from someone who is already losing track. They are not browsing ideas. They need the shared costs to stop scattering.
Pain
The pain is delayed cleanup. If the group waits until Sunday night, every missing receipt becomes a tiny negotiation.
TripTally angle
TripTally works best when the link goes out early. Everyone adds their own expenses as they happen, then the settlement summary is waiting at the end.

Good moments to use it
If someone paid for dinner, they can add dinner. If someone paid for gas, they can add gas. The job does not belong to one person.
A photo of a receipt in the chat still needs someone to enter it later. Put the number where the settlement will happen.
Settle before the trip energy disappears and every request starts sounding like a reminder.
Example
Everyone sees the same math instead of rebuilding it in the chat.

Questions
Earlier than you think. The best time is when the first shared charge happens, not when everyone is tired and packing.
Yes. Use the split editor on an expense when not everyone was part of that charge.
Yes. The settlement summary shows who owes whom so the group can pay each other back outside the app.
