What is the difference between bills and expenses in regard to recurring payments?

Can you define the difference between bills and expenses in particular with regard to recurring payments?

For example, how do you treat the following items:
Set monthly broadband amount paid by direct debit automatically from bank account.
Monthly hosting/servers payments
Payments to contractors.

Ideally where possible we would like them to be recurring so we dont have to worry about them.

Thanks
