Our Process
We areShopware experts
Successful Shopware shops are our DNA. We've been building on the platform for more than ten years – from the early days under Shopware 5 to the current Commercial Editions Rise, Evolve and Beyond. In that time we've delivered enterprise migrations involving millions of order lines, designed shop architectures for high-traffic brands like Bike-Discount and developed custom plugins for industries where no standard solution exists.
Our Shopware certifications cover development, architecture and storefront. More important than the paperwork, though, is the pragmatism that comes from real projects: we know when a standard plugin is enough and when custom code earns its keep, when a headless setup is more effort than benefit and how a cutover under full operations can be done safely. That experience we share transparently – even when it argues against scaling up complexity.
Whynextlevels?
You benefit directly from our developer expertise – with a dedicated contact who clears up follow-up questions with the team without detours. Together we analyse your shop, identify the real key areas and build tailored solutions without lock-in and without hidden costs. What we build belongs to you: code, documentation, Git history and infrastructure setups are documented well enough for any other Shopware agency to take over without friction.
As a Shopware Silver Partner with headquarters in Mönchengladbach and a branch in Düsseldorf we deliver enterprise projects at the speed of a specialised team – without the overhead of large consultancies. After the discovery workshop you receive a concrete fixed-price offer, a technical tech lead as a permanent contact and a sprint rhythm that does not end at go-live.
- Clean, documented code – no vendor lock-in
- Two locations in NRW – Düsseldorf & Mönchengladbach
- Fixed price after discovery – no hourly roulette
