Every account gets a MYOB number
QuickBooks lets you run accounts with no numbers at all. MYOB AccountRight needs a number on every account, and the first digit says what kind of account it is: 1 for assets, 2 for liabilities, 3 for equity, 4 for income, 5 for cost of sales, 6 for expenses, 8 for other income and 9 for other expenses.
We give each QuickBooks account its MYOB number under that scheme. Sub-accounts become detail accounts under a header account, so your profit and loss still reads in the order your accountant expects. Your accountant signs off the new list before any transaction moves.
