I do Net 30, so I'd be out 2 months worth of services. IMHO I specialize in keeping things painless when people work with me so I'd rather be out 2 months of revenue than a customer encountering game changing pain because I was ultra-harsh. I haven't made enough money to switch to accrual accounting so this is okay. I'm sure a day will come when I regret it, but it's been fine so far.
