The most significant and long-term cost factor of an ERP implementation is the actual cost of the software, which is typically dictated by the number of users the system will have. The average cost of ERP software is $8,265 per user over a 5-year period (or $137.75 per user per month). This is the average budget per user across businesses of all sizes over a five year period.
For small businesses, a typical range is $125 to $350 per user per month, and the range depends on the class and tier of the software and the functionality, technology, and integrations the software comes with.
