A successful online shop is far more than a product catalog with a checkout button. It requires carefully orchestrated user journeys that guide visitors from discovery through consideration to purchase with minimal friction. We design e-commerce experiences based on conversion research and real user behavior data, optimizing everything from product page layouts and filtering systems to cart recovery flows and post-purchase communication sequences that drive repeat business.
Our e-commerce implementations go deep into backend integration because the shop frontend is only the tip of the iceberg. We connect your online store directly to ERP systems for real-time inventory synchronization, automate order routing to fulfillment centers, and integrate accounting software so invoices generate automatically. Payment providers like Stripe, PayPal, and Klarna are configured with proper fraud detection and PSD2 compliance, ensuring secure transactions across all European markets.
Performance is a conversion factor that many shop operators underestimate. Studies consistently show that every additional second of load time costs measurable revenue. We build shops on modern frameworks with server-side rendering, optimized image delivery, and efficient caching strategies that achieve sub-second page loads even with thousands of products. Combined with mobile-first responsive design, these technical foundations ensure your shop performs brilliantly on every device your customers use.
Launching a shop is just the beginning of the e-commerce journey. We provide ongoing optimization services including A/B testing of checkout flows, SEO improvements for product pages, and analytics dashboards that reveal which marketing channels actually drive profitable orders. Our maintenance contracts cover security patches, platform updates, and performance monitoring so you can focus on growing your product range and customer base while we keep the technical infrastructure running flawlessly.
Sustainable revenue growth comes from systematic A/B testing at critical touchpoints: product pages, checkout flows, cart dialogs, and calls-to-action. We complement this with push notifications to recover abandoned carts and re-engage existing customers with offers. Combined with a well-executed SEO strategy, these measures ensure not only more visitors find your shop, but a larger share of them actually convert into paying customers.
Black Friday, seasonal spikes, or viral campaigns – your online shop must handle sudden traffic surges without sacrificing performance or availability. We architect shop infrastructure with load balancing, intelligent caching, and global CDN deployment. Through an API gateway, we orchestrate microservices and headless commerce architectures that scale independently – keeping checkout fast even when thousands of customers browse your shop simultaneously.
Selling internationally requires more than translated text. Professional internationalization (i18n) encompasses currency conversion, country-specific tax rates, local payment methods, and legally compliant processes. With Progressive Web Apps, we deliver an app-like shopping experience – offline-capable, fast, and installable – without the detour through an app store. Combined with consistent responsive design, you reach your audiences worldwide on every device.

Frequently Asked Questions
It depends on product count, integration depth and budget. We advise technology-neutral and recommend the platform with the best cost-benefit ratio.
We connect Stripe, Mollie, PayPal and other PSPs – including PCI-DSS-compliant tokenisation and reconciliation logic.
Yes. We implement multi-currency, multilingual stores and country-specific tax logic from day one.
Through optimised checkout flows, fast load times, trust signals and data-driven A/B tests on the pages that matter most.
Cost depends on catalogue size, B2B logic, integrations and design: a lean B2C shop with a template often sits below complex B2B e-commerce with tenants, price lists and ERP. Budget for hosting, payment fees and maintenance as well – otherwise the budget erodes after go-live.
International RFPs often name a specific e-commerce platform; compare licence, feature scope and roadmap, not only screenshots. Online shop development for checkout and UX should be signed off with test data, not only green smoke tests. We structure milestones with fixed price or scope caps so leadership and IT share the same assumptions. Typical projectable shops sit in the mid five-figure range; enterprise platforms above – individual proposal after a workshop.
B2B e-commerce needs clear role models: who sees which prices, who triggers approvals, how are framework agreements and tiers mapped? Without these rules the shop becomes a CRM duplicate and maintenance splits across ERP and shop. Customer accounts with multiple buyers, quote/order history, CSV/EDI interfaces and credit limits often matter – that distinguishes B2B from a classic B2C catalogue.
The e-commerce platform must deliver reliable APIs and webhooks or synchronisation breaks under peak load. Online shop development then covers not only the theme but cart rules and payment methods. We prioritise integration paths and measurable checkout steps before the layout is final-polished.
A Shopware agency delivers traceable releases: concept, UX, theme or plugin development, tests and documented handovers – not only buying a theme and hoping. Credible references in a similar industry, clear SLAs for operations and security patches, and explicit ownership of integrations matter.
As a Shopware agency we use staging systems, automated regression tests for checkout and alignment with ERP test tenants. Ask about monitoring and incident processes – that separates professional online shop development from one-off deliveries. B2B e-commerce on Shopware benefits from Rule Builder and commercial data models when master data is clean before launch. In short: deliverables and acceptance in writing, then the chosen e-commerce platform can grow with you.
In everyday language we say "shop"; internationally "e-commerce platform" means backend, catalogue, cart and APIs – practically Shopware, Magento or WooCommerce plus payments. Online shop development covers frontends, checkout flows and performance budgets; headless separates that layer from the backend. In RFPs align terminology: what does "platform" mean for licence, hosting and updates?
Having an online shop built means not only pixels but integration risk. For B2B e-commerce, context-dependent prices and approvals must hold under load tests with ERP simulation. We document terms in a project glossary so IT and management measure the same milestones.
Shopware fits the DACH region and B2B features well; WooCommerce when website and shop are tightly coupled with WordPress and the catalogue stays manageable; Magento for very large catalogues, multi-store and international role scenarios. The decision depends on integration depth, team skills and licence cost – not the logo alone.
Building an online shop should start with a proof of concept for critical integration paths. B2B e-commerce on Shopware often benefits from standard B2B packages; WooCommerce needs tighter plugin discipline. Check roadmaps: which e-commerce platform receives security updates for how long? Online shop development is planable when the platform fits strategically – not only short-term lowest price.
Depends on your requirements: Shopware for professional German B2B/B2C, WooCommerce for smaller shops with WordPress integration, Magento for international enterprise. We advise neutrally.
Yes, that is our specialty. We connect shops to SAP, Navision, Odoo, or custom warehouse systems. Real-time stock sync, automatic order transfer and invoice synchronisation.
A professional shop with custom design, payment integration and basic functions starts at around 15,000 €. Complex B2B shops with configurators or multi-channel correspondingly higher. Clear offer after requirements analysis.
Standard shop: 8–12 weeks. Complex projects with many integrations: 3–6 months. We work in sprints so you see progress regularly and can give feedback early.

Questions about e-commerce?
We advise honestly on shop systems, costs and strategy—without sales pressure (Björn Groenewold, CEO).
Having an online shop created pays off when checkout, payment route, and ERP connectivity are planned together—not when only a theme goes live without master data ownership.
| Use case | Benefit | Differentiation | Outcome | Next step |
|---|---|---|---|---|
| B2B shop with price lists and approvals | Shopware/WooCommerce with ERP logic | Not pure B2C template shop | Conversion-strong checkout | Shopware development |
| Relaunch with SEO and performance risk | Migration, redirects, and monitoring | Not CMS hub without shop focus | Stable relaunch without ranking drop | Online shop costs |
| Payment and shipping unclear | Payment and fulfilment route from one team | Not frontend design only | Measurable checkout without drop-offs | E-commerce solutions |
