I built TripMate after repeatedly running into the same problem on trips with friends and colleagues: expenses are rarely as simple as one person paying and everyone splitting evenly. Different people pay for different things, receipts contain items shared by only some of the group, currencies change across countries, and figuring out who should pay whom at the end becomes surprisingly messy. TripMate turns that process into a shared workflow — letting groups record complex expenses as they happen and automatically calculating the smallest set of transfers needed to settle everyone up.
Flexible expense splitting with multiple payers, participants, currencies, and equal, manual, or receipt-based allocation
Settlement optimization that minimizes the number of transfers required to settle the entire group
Multi-currency accounting with locked exchange rates for consistent balances and settlements
Collaborative trip management with invitations, role-based permissions, and expense approval workflows
Secure JWT authentication with refresh-token rotation and session management
Production-oriented Go backend structured around clean architecture and domain-driven design principles
