We have been using SAP B1 for nearly 10 years. We upgraded our ERP System in mid-2021 to SAP S/4HANA to accommodate our expanded business needs. IVC provided us professional service with high standards and the changeover to SAP S/4HANA was not without difficulty. The consulting team, led by the Project Manager Karen Chan, is committed and professional. They studied our flow, worked closely with our team; solved the problems and completed the key milestones on-time and within budget. We thanks for the good works they provided.
