It's designed to help the enterprise customer not you; i.e. they aim to get paid for services or products that you provide that they resell (directly or indirectly) before they pay you.
Example; one day 1 you provide a service to enterprise customer (the clock starts ticking), on day 2 they resell that service (with added value etc). The enterprise customer's customers either pay upfront (B2C), day 5 through 9 for customers paying by credit card, bank transfer etc, or pay on day 32 (B2B). Then on day 60 they pay you. So in the case of B2C your enterprise customer has cash in the bank earning interest for between 51 to 60 days, and for B2B customers for 28 days. So they always have a positive bank balance (no need for a rolling line of credit and risks involved), and they earn some extra cash because of it.
EDIT: further technical info.
The technical accounting term for this is positive cash flow. The opposite (paying you providers before getting paid by your customers) is obviously negative cash flow (like a old fashioned mom and pop shop; they buy the stock before their customers pay for it. Please note that modern supermarkets work nothing like this).
