Kashoo provides cloud-based accounting software, which includes mobile access through an iPad app. There are a million and one mobile accounting tools out there, but Kashoo actually offers double-entry accounting, which is what most bookkeepers, accountants, and, heaven forbid, the IRS prefer. In other words, Kashoo is more than simple recordkeeping and expense tracking. It's a full-blown accounting suite.
