It keeps everything sorted. And it’s as much calculator as organizer. You note who is responsible for what and how much they must pay, and as each party billed presents you with money to pay charges to your credit card or recompense for past cash transactions, Shareabill sorts it out until all t’s are crossed and i’s dotted. Furthermore, if there is a discrepancy with a charge that still requires discussion, messages can be posted to help bring clarity to such a situation. (For those “Who said they’d pay for the extra round at the bar last night?” moments.)
There’s really nothing too complex to Shareabill. It sports a sensible design, we think. You might prefer something a bit simpler and more amenable to free-form assembly of bills, but it’s easy enough that it will presumably cause little or no trouble for most users.
