Simple, familiar language. The principles of double-entry accounting are several centuries old. You can't get away from some of the terms and phrases that wouldn't normally come up in casual conversation, like debits and credits, general ledger, and chart of accounts. But the developers who have produced today's best-of-breed accounting sites only subject you to arcane language when it's absolutely necessary. You can't get around the fact that double-entry accounting is a complex process that must follow the rules, but these wizard-based services hide as much of the complexity as they can.

There's a good reason: automation comes with a price.
