Currently, I am embarking on a CPM (Corporate Performance Management) software selection project. This project is planned to be implemented by external consultants, but the budget range has not yet been determined. Therefore, I hope to leverage the community's insights to obtain a general price range for such projects in the market, so as to better plan and make decisions.

Specifically, what I need to know is: what is the typical fee range for a CPM software selection project led by external consultants? Does it vary significantly depending on the software vendor, project complexity, or consultant seniority? If you have relevant experience or information, I would greatly appreciate your sharing.

Thank you in advance, and I look forward to your valuable suggestions.
