Does not apply to prior plan license purchases. Cannot be combined with any other promotion or discount.

Plan Modifications

When reviewing your Study Set plans, you may identify some changes you would like to make to the original design. The BudgetWise Bundle provides you a FREE consultation with one of our plan specialists, including an estimate of the fees and time frame to have us modify the original design for you (Note: customization/changes can only be made to the fully-licensed plan, not a Study Set plan).
