No, and this is the single most common misread of net-30 on this board.
Net-30 almost always means 30 days after the close of the period, not 30 days after the spend. Your September earnings close on the 30th, the invoice generates in the first few days of October, and payment lands 30 days from there. So realistically the first week of November for money you earned on the 2nd of September — call it 60 days on the earliest days of the month and 30 on the last.
And the first payment is usually slower than that again, because it's the one where their finance team verifies your details for the first time. Budget for 45 to 70 days on payment number one, then it settles into a rhythm.
