yes, you are very correct in saying that. Worse still, some might give the "clerical" part of the work (i.e., putting the infor together) to an office clerk: paying office clerk rates for that part of the job but billing clients at the "accountant" rates, hehehe.
I don't think you need to disclose in your tax return every single individual trades, but make sure you have kept complete records to support your figures if you are picked for an audit.
