Our goal is to only charge you for the minutes you use on a server.
When you first get a server we pro-rate the service fee for the current calendar month, create an invoice and charge your credit card before proceeding with the setup.
When you get your second or subsequent server we also pro-rate the service for the current calendar month. But the invoice is dated at the end of the month. And your card is not charged until then.
At the start of each calendar month we invoice for all servers running at that point in time. We charge your card for those invoices.
When you shut down any server we add a pro-rated credit to your account. This credit comes off any amount that may be owed.
The credits you get on shutdown stay on your account. So if you have server left over running from last month and are billed for a full months usage at the start of the month. You still get the credit. And you'll therefore be billed less the following month.
Note that at the time of setup if you have one or more other servers with us there is no setup fee for VPSs. Otherwise the standard setup fee (typically $10) would apply for your first server.
Example: Order server 1 for $30/m on 14 February, we will charge your card $24 ($10 setup $15 pro-rated hosting). Come 1 March we will invoice and charge $30.
Order server 2 for $30/m on 15 March and we will create an invoice of about $15 ($0 setup, $15 pro-rated hosting). This invoice will be dated 31 March. Your card won't be charged.
Shut down server 2 on 16 March and we will add a pro-rated credit of about $14 to your account.
Come the start of April we will invoice for server 1 ($30). You'll have $15 less $14 = about $1 owing for server 2. We will charge your card $31.
Miscellaneous info: our billing is per millisecond. But since its only cents per hour typically that typically won't result in anything different than per minute billing.
Happy to clarify any questions about this you may have. Or if you can think of a fairer way to do it.
