There seems to be an accounting equivalent of Greenspun's tenth rule:

"Any sufficiently complicated financial reporting system contains an ad-hoc, informally-specified, bug-ridden implementation of double-entry accounting."

It's such a powerful yet simple way of thinking about money that anyone who builds a billing or accounting system should be intimately familiar with it.

Agreed; it's unfortunate that explanations are often filled with accounting jargon that obscure its advantages. The concept itself is awesome, and avoids so much pain down the line.
