usually a week sometimes that same day sometimes 2 weeks and others have waited 30,60 and even 90 days depends on who you work for

One month in arrears.  October check in the mail for August activities.

im working for Chaparral Energy. 90 days from the day I invoice. I told them "30day pay = $75.00 per hour and 90 day pay is = $85.00."
they chose $85.00. thats fine with me. I charge from the time i leave the house until i get home. i charge straight through the noon hour and 2 -15 min. breaks.
they love it.
