Why don't some of the chart of account have no numbers assigned to them
in Quickbooks when I look at the sample ?
Numbering your chart of accounts is an option.
Edit ==> Preferences
Click the accounting icon. Click the Company Preferences tab. There are
options for Use account numbers and Show lowest subaccount only.
I'm not sure of the option selected in the sample file. If you played or
modified it while testing, you could have created accounts with/without
account numbers.
