As with so many other service-orientated professions, the payment is done after the job is delivered. Sometimes, for example in case of a large job for a client you haven't worked for before, you could agree upon an advance payment, but the normal process is to bill after delivery. I usually invoice at the end of the month and cover up all the jobs that were done for that client. I have found out that it's nice to have payment terms, but when you deal with agencies these are worthless: they have their own and they stick to them...
I jump on the job quickly if pre-payment is offered since it indicates seriousness of the client.
