E-commerce Rescue:
From Stuck to Scalable >

We design and implement Shopify Plus architectures for manufacturers, distributors, D2C brands, and all B2C E-commerce companies operating at Enterprise scale. Our work covers zero-downtime migrations from legacy platforms, headless builds with Storyblok and Contentful, ERP and SAP integrations, and CRO-driven optimization. We recover stuck projects by resolving technical debt. We turn Shopify Plus setups into reliable sales tools that drive measurable ROI – particularly for brands expanding to the DACH market.

Commerce engineering that pays back

Recovering stuck projects

We take over failing implementations and legacy migrations from platforms like Magento or Shopware 5. Our engineers ensure a zero-downtime transition by auditing technical debt and stabilizing your production environment first. You receive a realistic roadmap with clear milestones instead of empty promises.

Unblocking marketing teams

When every content update requires an IT ticket, your architecture is slowing you down. We build Headless Shopify Plus environments with Storyblok or Contentful to give your team full operational autonomy. Conversion rate optimization is integrated from day one to ensure immediate business impact.

Engineering for high-throughput

Shopify Plus is the engine, but the real value lies in the integration layer. We connect your store with SAP or ERP systems to process millions of records without performance drops. Our solutions are designed for real-world traffic peaks, ensuring data integrity across your entire ecosystem.

Bridging your business to DACH

We help brands scale into Germany and other DACH markets without rebuilding their systems from scratch. By combining Polish operational agility with the process culture of hmmh Germany, we navigate local logistics, legal requirements, and payment methods.

Is Shopify Plus right for your scale?

Shopify Plus has evolved far beyond retail; it is now a high-performance engine for companies generating at least 50M EUR in annual revenue. We recommend this platform for organizations that prioritize operational peace of mind and want to shift their focus from maintaining server infrastructure to driving commercial growth.

For brands that need the agility to launch new markets in weeks, not months.

For businesses requiring custom logic for tiered pricing and volume discounts within a consumer-grade UX.

For companies stuck with high maintenance costs of Magento or custom builds, looking for predictable TCO and data security.

For brands entering Germany, Austria, or Switzerland that require full compliance with local legal and fiscal standards.

Frequently Asked Questions

Is Shopify Plus suitable for complex B2B operations and brands with annual revenue above 50 M EUR?

Yes – provided the architecture is designed correctly. While Shopify Plus handles high volumes well, Enterprise B2B scenarios usually require custom pricing logic, deep ERP integration, and often a headless layer to manage catalog complexity.

How does migrating to Shopify Plus affect Total Cost of Ownership (TCO)?

Migration shifts costs from CAPEX to OPEX, replacing unpredictable infrastructure maintenance with a predictable monthly fee. For brands moving from aging Magento setups, the TCO over 3 years is significantly more favorable, though initial investment depends on integration complexity.

What does a Shopify Plus rescue project with hmmh typically look like?

We start with a 1-2 week technical audit to map debt and critical failure points. We then follow a phased roadmap: stability first, then performance, then growth. Most projects reach production stability within 4-8 weeks.

When should an Enterprise brand choose Headless Shopify Plus over a native storefront?

Choose Headless when your marketing team is blocked by the release cycle of your IT department, when you need a single content layer serving multiple storefronts or markets, or when your design system can’t be expressed in Shopify’s native theme architecture. For most brands below 20M EUR with a single market, native Shopify Plus is faster and cheaper to implement.

Can the Shopify Plus checkout be customized for complex B2B needs and local markets?

Yes. Standard Shopify locks the checkout, but Shopify Plus opens it up. We use this access to build custom checkout steps that match your exact business rules. If you need real-time VAT/NIP checks for B2B clients, local payment and shipping options for the DACH market, or custom upsell logic, we make sure your checkout is built to drive sales.

How does Shopify Plus support multi-market rollouts, like expanding into the DACH region?

A single Shopify Plus plan includes extra stores, keeping your software costs down as you grow internationally. We set up these environments so you can run truly local stores—with their own stock, local pricing, and specific campaigns for Germany, Austria, or Switzerland. Finally, we connect all these stores directly to your central ERP and PIM systems, keeping your data clean and accurate across the board.
