It depends on the size and scope of the project but typically ranges from $50,000 to $150,000. Microsoft Dynamics CRM is a fairly comprehensive solution with a wide range of features, so the cost can be justified by the increased efficiency and productivity it brings to an organization.
Additionally, many Microsoft Dynamics CRM partners are willing to offer a fixed price for the project rather than charging by the hour, which can help keep costs down. And in some cases, the organization may be able to get a government or other subsidy to help cover some or all of the cost.
