Imagine if drivers delivered as slow as broker paid...

It’s a typical part of being in the “food chain” of payments. The farther down the chain you are, the longer you can expect to wait. A lot of companies use a minimum of Net 30 day payment terms, sometimes even 60-90 days, regardless of whatever your paperwork says. So your broker probably gets paid in 30 days at best, and still needs to pay you. If you see your money any faster than that, consider yourself lucky to be “prepaid”.
