A preference management framework allows for the management of vendor-based vendor declarations and of vendor declarations for customer's purposes, preference determination based on preference agreements, the provision of statements regarding the preference eligibility of goods based on preference determinations, and the printing of several preference related documents according to the relevant agreements. The framework is flexible enough for users to easily develop their own preference schemes for new preference agreements. Users may first define (or modify) their responsible areas for preference management by assigning (or removing) administrative units of a business to themselves. Then the users may begin the preference processing by choosing one of their assigned administrative units and any preference agreements relevant to that administrative unit may be automatically determined for possible following steps in preference processes which can now be started.
