The latest version of the Easy Royalties software supports bundled products.
What are bundles? Bundles are products that consist of other products. Examples of bundles include sets, CDs, hymnals.
CDs and hymnals are bundlles of songs. A bundle might consist of a printed book and a digital book. Or a bundle might consist of a teachers guide and ten workbooks.
With this royalty software you can create a bundle for all of these. For each part of a bundle you can enter the quantity and the percentage of revenue that should be allocated to a title.
When you look at a title record you can view all bundles that contain this item.
