Upgrading an ERP system can be costly due to expenses associated with software, hardware, consulting fees, training, and opportunity costs of internal staff time spent on the upgrade project. In addition to the direct costs of the upgrade, organizations must also budget for ongoing infrastructure costs, maintenance and support contracts, and smaller additional projects needed to customize and improve the ERP system over time. Careful evaluation of current systems and business needs is necessary to determine if an ERP upgrade will provide benefits that outweigh the significant financial costs and long implementation time required.
