MultiVariants - Bulk Order for Shopify got 50th active installation in the Shopify app store. It took us a month to reach this. We didn't start any notable marketing yet. Mainly coming from the Shopify app store listing. The app is yet fully free.
We are working on our new paid plans with a bunch of new features based on eCommerce wholesale merchants.
