You get paid the day you check out of in house. If by some chance financial is behind they will then pay you within 7 days, but that's rare.
Depending on the weekday you check in and how long you stay in house, they submit payment requests on Monday and checks arrive on Friday, sometimes Thursdays. So in most cases you will walk out of there with a partial payment; once your check out labs are clear they send a check by mail to complete payment.
