It's easy to duplicate bills
I have reported 6 bills today and duplicated some of them in many ways. If I double click the "submit" button, the bill is duplicated. If a network error happens, the bill is duplicated again. The server's availability needs kinda improvement.
But after all, it's an awesome website and we are switching to it from billmonk.

I’m not sure this is completely fixed (it’s not something we’ve seen on our test devices, so it’s hard to diagnose). If you see this issue, please emails support@splitwise.com.
