If there are material changes to scope of work during the project, we discuss and adjust the project plan and quoted hours accordingly in collaboration with you. We do our best to provide an estimate with the information we have available, and always let you know up front if details come to light that can affect the quoted number of hours. We always make sure we have your approval to proceed if changes in project scope require additional hours of work.
Quite commonly, clients wish to increase the project scope or add additional features as they see the project develop. We understand this, and will always try to facilitate any changes or additions to the project during the process.
