Important note - Once you have your file downloaded from ACT!, you'll need to split the contacts' names into separate columns for First Names and Last Names, otherwise Ace of Sales will not be able to import your file. To find step-by-step instructions to split the columns in Excel, check here (it's actually pretty easy to do!).
To import your CSV file into Ace of Sales, go here.
There is also a dropdown menu on that screen under "Search by Product" to find instructions for older versions of ACT! :
1. Click "ACT! by Sage 2010 Family of Products"
2. Choose year and version
3. Choose Export.
