In ERPLY you can set special product types for your products.
Matrix: Matrix products can be used for selling products with different sizes. For example footwear, clothing items etc.
Assembly: Assembled products can be used to sell products that you have made, assembled, or bundled together into a secondary product. The components of assembled products may or may not be sold separately.
Bundle: in ERPLY you can combine products that you want to sell together as one. When you create a bundle ERPLY will pull the products included in the recipe out of inventory every time the bundle is sold.
