🛒 For Shopify Merchants

Seven Apps Through Shopify Review. Built by a Merchant's Studio, Not a Growth Team.

JMS Dev Lab is a verified Shopify Partner in Cork, Ireland. Seven of our apps are live on the App Store — scheduling, spam protection, profit protection, repairs, valuations, marketing, commissions — and three have genuine free plans. When you need something the App Store doesn't have, we build it fixed-price.

7 approved App Store apps · Free plans on 3 · Custom Shopify work from €3,000 fixed
