Webcellent GmbH

Shopware solutions built for clean, scalable growth

Has your Shopware system grown over time, become technically outdated, or no longer reflects your current processes properly? Webcellent supports you with the conception, development, migration and long-term evolution of demanding Shopware projects.

We combine e-commerce expertise, technical development and process understanding to create shop systems that not only look good, but also work reliably in day-to-day operations, remain easy to extend and grow with your business over time.

Webcellent – Shopware agency based in Bielefeld

Webcellent GmbH is a digital agency for online shops, custom software, web apps and integrations. Our focus is on technically demanding e-commerce projects with Shopware and Shopify.

We develop new shops, modernise existing systems and support you with complex relaunches and migrations. We do not look at the frontend in isolation, but at the entire commerce system: product data, categories, variants, integrations, technical SEO, tracking, performance, order processes and the connection to existing business software.

You work directly with an experienced team. We explain decisions, technical dependencies and project effort transparently – without unnecessary agency layers and without one-size-fits-all solutions.

Migration and relaunch on Shopware 6

Migrating or technically modernising an existing shop to Shopware 6 is far more than a simple update. Existing product structures, plugins, custom functions, integrations, SEO-relevant URLs and business processes must be analysed, reassessed and transferred in a controlled way.

We support you with:

• the technical analysis of your existing shop system
• the migration of products, categories, customers and orders
• the transfer and clean-up of product data
• the redevelopment of custom functions and business logic
• the review and adaptation of existing integrations
• the implementation or transfer of an existing design
• the creation of a complete redirect concept
• the preservation of relevant rankings and existing URL structures
• testing, data validation and a controlled go-live
• ongoing maintenance and further development

Even with complex, historically grown systems, we make sure that your key processes remain intact and that the transition takes place without avoidable data loss or operational disruption.

Product data, variants and category structures

A high-performing shop starts with well-structured data. Unclear attributes, inconsistent variants, missing filters or historically grown categories make usability, SEO, integrations and future enhancements more difficult.

We support you with the conception and technical implementation of:

• product and variant models
• properties and attributes
• categories and shopping experiences
• filters and search logic
• customer-specific prices and assortments
• product imports and data migrations
• integrations with PIM, ERP and inventory management systems
• custom product configurators
• automated data flows and product feeds

We do not structure the data solely for your current shop. We design it in a way that also supports future requirements and can grow with your business.

Integrations and custom Shopware development

Many successful Shopware projects require more than standard functionality. We develop custom extensions and connect Shopware to your existing systems and processes.

This can include:

• ERP and inventory management integrations
• PIM integrations
• custom import and export processes
• payment and shipping providers
• CRM and marketing systems
• voucher and reservation logic
• external platforms and marketplaces
• custom backend and administration functions
• custom Shopware plugins
• APIs and middleware solutions

Our goal is not to create as much custom development as possible, but to build a technically sensible solution that remains maintainable, understandable and extensible over the long term.

Technical SEO from the start

We do not add technical SEO only after launch. Relevant fundamentals are already incorporated into the conception, migration and development of your Shopware project.

We take into account:

• URL and category structures
• canonicals and indexation control
• variant, filter and parameter pages
• metadata and structured data
• internal linking
• redirects for relaunches and migrations
• loading times and Core Web Vitals
• crawlability and technical errors
• product feeds for Google Merchant Center
• Google Search Console and tracking fundamentals

This helps prevent technical and SEO-related decisions from having to be corrected later with unnecessary additional effort.

Performance, conversion and mobile usability

Your Shopware shop should not only function technically. It should also guide users reliably to the right product and through the purchase process.

For new shops and ongoing development, we also consider:

• mobile user experience
• loading times and frontend performance
• product detail pages
• navigation and search
• cart and checkout
• trust and conversion elements
• technical accessibility
• tracking and analysis
• continuous optimisation after launch

We do not treat design, technology, product data and user experience as separate disciplines, but as parts of one connected commerce system.

Operation, maintenance and ongoing development

We continue to support your Shopware system after launch. Depending on your needs, we provide maintenance, technical optimisation, new functionality or planned ongoing development within a defined monthly budget.

Possible services include:

• updates and security checks
• technical error analysis
• performance optimisation
• extensions to existing functionality
• adaptation of plugins and integrations
• new product and process logic
• technical SEO optimisation
• support for tracking and data feeds
• ongoing development and consulting
