Your store should not break when the traffic arrives.

What we do

Shopify Plus development, migration, and CRO.

We are a Shopify Plus partner and an engineering firm. That means high-performance storefronts on Hydrogen and Liquid, zero-downtime replatforming from Magento or WooCommerce, checkout extensibility that survives compliance review, and a conversion programme that keeps working after launch. Twelve of our own apps run on the Shopify App Store, so we meet the platform's limits on our roadmap before you meet them on yours.

Key Challenges

Is your store leaving revenue on the table?

Slow checkoutCarts abandoned at the finish lineEvery extra second and form field between cart and confirmation cuts completed orders.
Platform limitsYour platform fights your roadmapTemplate stores hit a wall the moment you need custom bundling, pricing, or fulfilment logic.
Fragmented dataInventory, orders, and CRM never agreeDisconnected systems create overselling, delayed dispatch, and reporting nobody trusts.
Peak fragilitySales events become outagesInfrastructure that cannot absorb a spike turns your biggest campaign into an incident.
The difference

Why we are different from every other Shopify agency

We ship our own products, not just client work.

Twelve Devsinc apps run live in merchant stores from the Shopify App Store. We hit the platform's limits before your roadmap does.

We are engineers who understand merchandising.

Hydrogen, Remix, Checkout Extensibility, Shopify Functions. Also inventory, CPQ, and why your best-selling variant keeps going out of stock.

We stay after go-live.

Peak event readiness, Core Web Vitals work, and a support motion measured in conversion rate, not ticket volume.

Process

How a Shopify engagement runs

01AuditTwo weeks on your store, data, and stack. We benchmark checkout, Core Web Vitals, app load, and integration debt, then rank fixes by revenue impact.
02ArchitectureData models, URL map, integration contracts, and the theme or Hydrogen decision. Signed off before anyone writes code.
03Build & MigrateStorefront, checkout, and integrations built in sprints against a staged catalogue, then a rehearsed cutover with rollback points and zero downtime.
04Optimise & SupportExperiment backlog, Core Web Vitals work, peak readiness rehearsals, and monthly reporting on conversion rate and revenue per session.

FAQs

Shopify questions merchants actually ask

Still unsure? Get a free store teardown.
Let's talk
How much does a Shopify Plus build cost?+
Scope drives the number, so we quote after the teardown. A focused theme build sits at the low end; a headless Hydrogen storefront with ERP and multi-region checkout sits at the high end. Either way you get a fixed scope and price before any code is written.
How long does a migration take?+
A single-region catalogue on a standard theme typically runs eight to twelve weeks from kickoff to cutover. Complex migrations with ERP integration and multi-store rollout run four to six months.
Will we lose SEO rankings or order history when we migrate?+
No. We map every indexed URL with 301s, preserve titles and structured data, and monitor the redirect map for ninety days after cutover. Interwood grew 55% after exactly this process, with zero downtime.
Can you work with our in-house developers?+
Yes, and it is our most common model with larger merchants. We work in your repository and review process, and hand over documented code with your engineers on the pull requests.
What happens if our store goes down during a sale?+
Retainer clients get a rehearsed incident runbook, a named on-call engineer, and a war room for peak events. Most peak incidents are third-party apps or scripts rather than Shopify itself.
Why does being a Shopify Plus partner matter?+
Plus partners get early access to platform features, direct Shopify support channels, and proven experience with high-volume merchants.
Do you build custom Shopify apps?+
We run twelve of our own apps on the Shopify App Store, and we build private apps for merchant-specific operations.
How do you prepare stores for peak events?+
Load testing against a realistic traffic model, checkout hardening, an app audit, and a rehearsed war room runbook with named owners and agreed rollback points.
What does ongoing support look like?+
A managed-services pod with monitoring, security patching, performance work, and a monthly CRO roadmap, reported against conversion rate and revenue per session.
