The Package Manager includes the ability to download package reports. Each Package includes a "Reports" column with 2-3 report options depending on the type of package.
The first icon under Reports is to "View Orders" processed for that package. See the image below. Clicking that will load all orders processed for that package from the Orders tab.
Once the orders are loaded on the Orders tab, click "Export Orders" to export a list of all packages. See below:
The second icon under Reports is to download a CSV of all orders and individual tickets generated for each of the performances included in the package. See below
The third option is to get the data summarized directly from the Orders page.
