Once we receive a customization proposal, we will discuss the request and then send you an estimate of how many hours it will take to fulfill the customization. The hourly rate for customization is listed in the pricing page
. For basic/standard license it is $50/hr and for enterprise license it is $150/hr. Additional fees may apply at our discretion, but if that happens (very rarely) we will include it in the estimate.
