Most of our clients prefer the convenience of a yearly invoice. However, we are happy to set up monthly payments as well. For the base, assist and advise plans we generally prefer at least a 3-month agreement. That said, we are not interested in locking you into an agreement you do not want to be in. Our goal is to be so valuable to your business that you would not imagine going elsewhere. If for any reason you wish to cancel you may do so at any time without penalty. If on our servers, we will even assist you in migrating to a new host with no hard feelings.
With our add ons and partner plans we do occasionally ask for a commitment of 12 months. This is typically for larger plans involving us retaining additional resources to fulfill the service agreement.
