When do you take money from my account?

In the beginning of the month? Or during the day, when I was registered? How do I know?

Money removed at the end of each pay period. The first pay period concludes the month after the beginning of the use of a hosting. In this case you will receive reminder on an e-mail, with which you were registered with the site. Also, if you ordered additional services or you have overusage on  resources, you will get statement with your balance on services you used.
