2D labels get your inventory checked into FBA faster and without manual processing fees, and FNSKU labels prevent Amazon from commingling your inventory with other sellers' possibly damaged or counterfeit versions of the same products. But Seller Central's built-in tools for 2D and FNSKU labeling are clunky and hard to use. That's why we developed 2D Transit: to make labeling easy, prevent errors, and save on labor, time, and fees.
