Starting a LLC

I am developing a website that I will need to register as a LLC. My problem is I did not expect to have to do that since I am a sole proprietor so I am a little unprepared. I do not have a business checking acct, or a business credit card and I really don't want them because after a few very minimal start up fees I won't need them.

Does anyone know from personal experience is it ok if I just pay for my business licenses on a personal credit card?
