In short
- The decision is about speed and control, and you cannot have the maximum of both.
- Fees are the easiest part to model and the least likely to decide it.
- Most brands end up doing both, and the question is which products go where.
What does FBA actually buy you?
Speed to the customer and the badge that comes with it. Both affect whether a listing sells, not just how it ships.
The question is not which is cheaper. It is which one you can live with when something goes wrong.
When does your own warehouse win?
When the product is awkward, slow moving, or you need to control what arrives in the box.
