In Salesforce CPQ, a bundle is a group of products that are known to be sold together. There are three types of bundles: static, configurable, and nested1. The bundle configuration is a significant part of CPQ, and it can make selling complex product offerings easier by providing sales reps with premade product bundles to choose from1. However, whether a customer needs a bundle configuration or not depends on their specific needs and preferences2. Therefore, it's important to introduce the concept of bundle configuration as part of a CPQ project, but the decision to implement it should be left up to the customer2.
