I use net 30 terms. Average time between invoice delivery to invoice deposit in my bank account appears to be approximately 2 weeks, depending on whether they decide to pay by snail mail or ACH transfer.

I've never had a client be late with payment. I wouldn't say I get "nervous" if they don't pay within 2 weeks, but given that I'm spoiled by the average I've experienced, it would probably prompt my attention if they'd not at least started the process within that time frame.

From what I can tell most of the companies I work with appear to be eager to get the invoice process over and done with.
