Whitepaper (DE): 5 AI workflows for SMEsAs a Shopware agency and Shopware Silver Partner we build online shops that measurably sell – from migrating to Shopware 6 and custom plugin development to connecting ERP, PIM and SAP systems. Our e-commerce consulting and e-commerce agency guide merchants from Mönchengladbach, the Rhineland and the entire DACH region from platform selection to day-to-day operations: B2C, B2B and D2C, headless storefronts and performance optimization for shops handling thousands of orders a day. Every project starts with a free initial consultation and a clear effort estimate.
On top of that come app development for iOS and Android – with references such as Borussia Dortmund and Super RTL (Toggo) – and custom software development with a clean system architecture, CI/CD and predictable releases. As an AI agency we bring automation, AI workflows and digital assistants to mid-sized companies – from strategy and workshops to roll-out in daily business. Teams at our offices in Düsseldorf and on the Lower Rhine work in fixed sprints with dedicated contacts – on site in the Rhineland or remotely across Germany. After go-live we also take care of hosting, maintenance and further development.
