Increase payment volume by 280% with frictionless group splits
Bill Split is a mobile app for fast, transparent group expense management.
Users split bills in seconds, assign custom shares, and see balances update automatically in real time—centralising payments and reducing social friction around shared costs.


Bill Split is a mobile app for shared expense management. It lets you define custom contribution shares and manage group payments from a single interface.
The platform supports large groups and complex scenarios. All calculations are automatic, reducing errors and eliminating the need for manual reconciliation.
Debts and balances are updated in real time for full transparency and to prevent disputes.
Before launching the product, the business faced typical market constraints:
Manual expense splitting caused errors and unnecessary conflicts.
Most apps struggled with 5-10+ participants and uneven shares.
Multi-currency splits were inconvenient, slow, or inaccurate.
Too many steps reduced usage frequency and repeat behavior.

The turning point
In shared payment situations, even minor complexity creates hesitation, especially in social contexts where speed and clarity matter.
Every additional step, input, or confirmation increases friction and raises the likelihood of mistakes, awkwardness, or abandoned splits.
When bill sharing becomes instant and predictable, usage frequency increases naturally and the product integrates into everyday group behavior.
Based on research, several deliberate decisions were made:
Split bills instantly with minimal input.
Built for large groups and uneven shares by default.
Accurate multi-currency splits with live rates.
Debts rebalance automatically as payments happen.

Record expenses on the go.
Live exchange rates are accurate.
Reliable, even under heavy usage.
