Amazon limits the amount of initial inventory based on size and space. You would have to send the box dimensions over to your account manager to confirm how many units can be sent in initially. Once we start onboarding, we can figure out how many units you can send in for the initial load-in. The limit only increases when sales start going up. This is why we recommend starting earlier – so that your limits can go up for FBA, and you will be set up for success going into your peak selling season.
