?do hosting companies take money out automatically every month?
I'm assuming so, but not sure.
do i do it manually?

It depends on that form of payment. If you pay with a card, yes, you'll be automatically charged each month/year etc.

Some host give you the option of manual payment or subscription payments. Both options are easy to setup.

That is recuring payments. You can install them using any payment processor. 2checkout is the one you can use for sure and they do allow that.

yes, they automatically charge you unless you unsubscribe to that auto payment scheme.

I think it depends on the webhost company or in your user account. There is some sort of settings there whether its recurring or not, you can set them yourself if you want it to bill automatically or manually.

Most give you the option to choose automatically or manually. By default I think its selected to be auto. It all depends on the hosting company.
