The Copy Company functionality may not be the best choice if, for any reason, you wish to create a company with the same exact setup as one of your existing companies, but with none of the existing data; you would have to go back through the new company and manually delete all of the documents and entries. If your license does not allow you to delete posted documents or ledger entries, your Microsoft Partner would need to delete these records for you. However, if you do wish to create a new company populated with your current settings and documents (e.g. for testing purposes), this functionality could be a great asset.
