Choose Interad if

Your revenue runs through Coupang and Naver Smart Store. Interad is the marketplace-first specialist, which matters because marketplace ranking, ads and reviews are their own discipline separate from owned-store work.

Choose 300CBT if

You are building or scaling an owned Shopify store, especially for global expansion. As a Shopify Plus Partner with a verified 4.5/5, it is the clearer DTC and cross-border build choice in this pair.

The honest caveat

The two are not really substitutes; they serve different models. Many brands eventually use both, a marketplace specialist for Coupang and a DTC partner for Shopify. 300CBT's rating rests on only 2 verified reviews, and Interad has none yet, so request live account examples.
