Many programs on the market limit your ability to import or export data.  PestaRoo does not.  You have an unlimited ability to import or export any or all of your data at any time.  For example, you can purchase a simple list of the households in your county and import them directly into to PestaRoo for your marketing efforts. Or, if you want to export all you customers (for a mail merge) of a certain type or from a certain town, you can!
