Proefschriftmaken.nl is a broker that helps students to print their theses. They use our ERP system as their backend for Quotations, planning, and invoicing. In this project, we designed and created a portal used by their customers to check, complete and correct order information. Customer changes are visualized in a dashboard, and an employee approves those changes. The approval triggers an update and recalculation of the order in the ERP system.
