Technically sound

Whether you are building a new web shop or rebuilding your existing one: we implement your solution on Magento or Shopware – tailored precisely to your requirements.

We use standard features where they fit. Where your business needs more, we develop custom solutions – upgrade-safe and maintainable for years to come. We can host the shop for you, or you run it in your own environment.

What we build

B2C & B2B web shops

From consumer shops to B2B portals with customer-specific prices, closed areas and approval processes – on Magento or Shopware.

Product configurators

Configurable products with configento, integrated into product page, cart, order and production.

Custom extensions

If a feature isn't available as an extension, we develop it – cleanly encapsulated and upgrade-safe.

Shop plugins for providers

You offer payment, tracking, logistics or other services? We develop your plugin for Magento and Shopware so shop owners can easily integrate your service.

Frontend & performance

Responsive, fast storefronts in your brand's design – for Magento with Hyvä if you like.

Multilingual & international

Several countries, languages, currencies and domains from one system.

Integration into your system landscape

A web shop is not an island. It only really saves work once orders, stock, prices and customer data flow automatically between the shop and your systems: no double entry, no manual transfer, documents in one place.

We analyse your existing IT and processes and connect the shop via interfaces.

  • ERPe.g. SAP – exchanging orders, status and shipments automatically
  • Accountinge.g. DATEV
  • Postal & shippinge.g. Deutsche Post / DHL with Print-Mailing and POSTAKTUELL
  • Paymente.g. Mollie, Klarna, PayPal, SEPA direct debit with mandates
  • Government processese.g. digital vehicle registration via CarTrust
  • Search & marketinge.g. FACT-Finder, OpenSearch, CleverReach, Brevo, Trusted Shops
  • Your own systemsvia XML, CSV, SFTP or REST API

Experienced developers

Shop systems like Magento and Shopware are technically demanding – far more so than a content management system. At justSelling, developers with many years of experience work on exactly these platforms – supported by AI tools. And because we also run and maintain your shops, we develop with years of operation in mind.

Developing faster with AI

With Claude Code we analyse, develop and test faster – an experienced developer reviews every result.
