Under the terms of the deal, businesses that sell through Shopify will be able to use their existing accounts to apply to sell on Walmart Marketplace as well.

Walmart said it expects to add 1,200 Shopify vendors to its marketplace website by the end of 2020 as a result. Walmart Marketplace already offers items from more than one million businesses.

Walmart’s ecommerce sales surged 74% in its domestic US market during the three months to March 31 and it said marketplace sales “outpaced the overall business”.
