01 / Ecommerce

From a first storefront to a full migration off a legacy platform, we build and run Shopify like an engineering team, not a theme shop. Custom apps, checkout-safe migrations, and ongoing consultancy for stores that have outgrown templates.

01Capabilities

01

Storefront builds

Headless or themed storefronts on Shopify/Shopify Plus, built for merchandising flexibility and checkout speed.

02

Custom app development

Private and public Shopify apps — subscriptions, custom pricing logic, inventory sync, anything the App Store doesn't cover.

03

Platform migration

Moving from Magento, WooCommerce, BigCommerce, or a custom cart to Shopify without losing SEO equity or order history.

04

Consultancy & audits

Technical and conversion audits for existing stores — checkout drop-off, app bloat, Core Web Vitals, theme architecture.

Marked as demo until the real quotes are cleared for publication — we won't print a testimonial we can't attribute.

01
“They mapped every redirect before touching DNS. We didn't lose a single ranking position through the migration, which is the part everyone else told us to just accept as a risk.”

Renata Okafor

Head of Ecommerce, Tidewell Supply · demo

02
“We'd spent two years being told our billing model was 'too custom' for Shopify. Turned out it just needed someone willing to build the app instead of finding a workaround.”

06FAQ

Yes — we run migrations on a staging domain, validate the full order/checkout flow, then cut over DNS during a low-traffic window with a tested rollback plan.

We work across standard Shopify and Shopify Plus, and advise on when Plus's checkout extensibility and script/flow tooling actually justify the upgrade.

We regularly inherit and stabilize existing apps — we'll audit it first and tell you honestly whether to patch or rebuild.
