Using it, you can easily control all costs and to determine who owes whom and how much. At the same time, you can use different currencies (which is especially important on a trip). All currencies exchange rate are translated automatic when you change the main (default) currency. Available detailed report where you can see the costs by category, by the people, by currencies. The report by category can also be viewed for each participant. You can send report to all partivipants via e-mail.
