You get paid a wage for what you do and a return on what you own. When you say net, it should be the bottom line after all expenses are taken out - including your own fair market wage. What would you have to pay someone to do the job you are doing? If you don't include owners wages as an expense your numbers are lying to you.
When you read 20k gross and netted 14k my guess is the 14k was what was left over before figuring what a fair market wage would of been to complete the work? I don't care if you are a sole prop, llc or S corp.
