Your new database is ready for you to start entering data. If you ordered a data conversion it can be imported now or after you have completed the next steps (Note: If you are receiving a FULL conversion install it now and then complete any data entry steps you wish. If you are receiving a partial data conversion, e.g., Products only, then you can enter any data you wish in the following steps except for the data you are having converted as it will be overwritten).
If you are not using Client/Server you can backup your database anytime by clicking Tools -> Backup from the text menu (this feature does not work for Client/Server. Use a Windows backup utility and backup the data directory.
