The close, the accounts and the statements behind them — how your books are built, and what they are actually telling you.

Accounts receivable aging report: the oldest column is income you already booked
The aging report is a statement about your books before it is one about your customers. What the total should tie to, what is really sitting in the 90-plus column, and which lines are not receivables at all.

Invoice payment terms: what each one costs you in days of cash
Each term on your invoice has a price in days of your own cash. What net 15, net 30 and 2/10 net 30 each cost, which bucket each puts you in on the aging report, and who owes you interest when they pay late.

Four tax classifications, four ways of paying yourself, and one fact underneath all of them: a draw comes out of equity, so it never reaches your profit and loss.
