oContis Studio
— Shopify Plus Agency London

[ˈkon.tis] /styOOdIOh/

We are a London Shopify agency for established DTC brands on Shopify Plus whose stacks no longer keep up with the business. Often because a previous agency built something that does not scale.

We restore order first, then stay as your long-term Shopify development partner.

Through , we run a structured Shopify stack audit across theme, Shopify app store footprint, data model, integrations, and checkout, then deliver custom app development, theme work, and checkout extensions where off-the-shelf tools fall short. One agency. One roadmap.

See Shopify development services or book a stack assessment if Shopify has become a constraint on what you want to do next.
