Amazon.com Inc. is guiding merchants who use the Amazon Webstore technology platform, which Amazon will shutter next year, to Shopify Inc.’s e-commerce platform.

The two companies in recent weeks have worked together to create tools that will help Webstore merchants migrate their stores to the Shopify platform with minimal work or downtime, Shopify’s chief platform officer Harley Finkelstein tells Internet Retailer. The migration tool will “pull all the data that can be pulled in,” so that merchants who want to move to Shopify won’t have to, for example, re-create their product catalogs or rewrite product descriptions. Shopify also is working with Amazon to make it possible for Shopify merchants to sell goods on Amazon’s marketplace managed through the Shopify platform.

Finkelstein calls Amazon’s selection of Shopify as the “preferred migration provider” a “wonderful endorsement for us.”

“Shopify exemplifies the value of simplicity in an increasingly complex world of commerce services,” says Patrick Gauthier, vice president of Amazon Payments, in a statement. “We are excited to work together with Shopify to create best of class solutions that help merchants integrate Amazon offerings.”

Shopify, which is based in Canada and went public in May, reported in July that revenue grew 89% year over year and that 175,000 merchants use its services, which include payment processing through Stripe Inc. Six of the e-retailers ranked in Internet Retailer’s Top 500 and Second 500 Guide say they use Shopify’s services. Fees for its e-commerce platform range from $29 to $179 a month, plus optional upgrades. The monthly fee Amazon published for Webstore as of March was $79 plus a 2% transaction fee.

Shopify in recent months has also worked with Facebook and Pinterest to be among the first e-commerce platforms to enable merchants to feature Facebook Buy buttons and Pinterest buyable pins. Further in its work with Amazon, Finkelstein says that starting today merchants using the Shopify e-commerce platform today can turn on the ability to use Login and Pay with Amazon, Amazon’s payment gateway that lets consumers use their Amazon credentials and stored payment information on other e-commerce sites. They can also use Fulfillment by Amazon to fulfill orders placed on their own websites.
