Only if you want to!
We have some clients that like to have a contract in place when they get started with our services. We can provide that and get everything ready for you.
That said... If you hate contracts as much as most of clients (and don't want to get locked into anything), we don't require them.
You can use our service month to month. We just ask that you give us a 30 day notice if you're going to cancel your account..
