Question

what is the main advantage of building a digital product from scratch? faster implementation upfront costs control over customization and updates licensing fees

Explanation:

Building a digital product from scratch allows the creator to have full control over how the product is customized to meet specific needs and how it is updated over time. "Faster implementation" is not an advantage of building from scratch (it's usually faster to use existing solutions). "Upfront costs" and "licensing fees" are typically disadvantages or costs associated, not advantages. So "Control over customization and updates" is the correct advantage.

Answer:

Control over customization and updates
