Is it un-professional to ask for payment right after a job when u 1st are starting out in this biz? I'm going to really need the cash anyway, so I hope not to make a bad impression. I'd like to get 20 or more customers out of these several thousand flyers I'm doing, but if I only get 10, then I'm sure I'll need every dime I can get asap. When I was removing snow from drives, people didn't mind paying right after at all. Some would pay me in the middle of working. I bought a little recipt/sales book to use. I know it's "old school" but surely this is ok for starting out. I figure then at least we both will have a recipt of the transaction. Seems most of u guys send invoices. But then how long do u have to wait 'til u get the check? Seems that u may be waiting for weeks in some cases b4 u get paid.
