Shopify Plus Development
Shopify Plus, engineered for scale.
Custom themes, headless storefronts, app development, and deep integrations. Shopify Partners who think in systems.
The architecture we build
Storefront, core, custom apps, and integrations — engineered as one system.
Hydrogen or Liquid in front, Shopify Plus in the middle, your ERP / OMS / 3PL behind, our custom apps stitching it all together. Every layer treated as production code, not a theme tweak.

What Destm adds to Shopify
Out of the box → with Destm AI layer.
Shopify gives you a great storefront. Destm adds the layer most agencies skip — AI search, dynamic pricing, predictive inventory, and personalization rendered into Hydrogen.
- Static product grid
- Search by keyword match
- Manual price adjustments
- Hand-curated recommendations
- Vector search with intent ranking
- Dynamic pricing inside guardrails
- Personalized recs from real signals
- AI alt-text + SEO from CMS
The same Shopify Plus instance. The same Hydrogen frontend. The Destm AI layer renders into your existing storefront — no rip and replace.
Why Destm
We layer AI into Shopify builds — most agencies stop at theme.
From AI-powered search and personalization to predictive inventory, every Shopify build includes an AI opportunity assessment. Intelligence is not an add-on — it is the foundation.
Shopify builds across the maturity curve.
From DTC startups to enterprise brands processing serious GMV. We have seen the edge cases, the platform limitations, and the scaling challenges that surface only after launch.
Full-stack engineering, not just theme tweaks.
We build custom apps, design data architectures, engineer CI/CD pipelines, and optimize at every layer of the stack. Systems thinking, not page building.
The Shopify decision
When to choose Shopify Plus.
Shopify Plus is powerful, but it is not the right fit for every business. Here is an honest breakdown so you can make the best decision for your commerce stack.
Best for
- D2C brands that need a fast, reliable storefront with built-in payments, fulfillment, and marketing tools
- Fast-growing startups that cannot afford 6-month build cycles and need to launch in weeks, not quarters
- Brands going headless with Hydrogen for full creative control while keeping Shopify's operational backbone
Not ideal for
- Heavy B2B operations with complex pricing tiers, custom quoting workflows, and multi-buyer approval chains
- ERP-first businesses where the commerce platform must deeply integrate with SAP or Oracle as the system of record
Typical investment
Custom Hydrogen builds scale with design complexity, number of integrations, and whether you need custom app development. Standard Shopify Plus theme builds start lower. We scope every project honestly so there are no surprises.
Common workstreams
Shopify Plus is simple until operations get complex.
The engagements that recur. Most brands need two or three of these, not all seven.
Replatforming to Shopify Plus
Migrate catalog, customers, orders, and URLs off the legacy stack with parity proven before cutover.
