This depends on a number of factors including but not limited to the size of the organisation, the amount of data to migrated from the old systems, the level of client participation in the implementation project, the number of business areas involved and the amount of customisation required. Generally we only cost an implementation once we have analysed the systemt requirements of the prospect. However, as an example a typical 15 user full implementaion of NetSuite ERP and CRM would normally require approximately 15 to 25 man days to implement with a custom e-Commerce site requiring a further 10 man days.
