Data first
Before anything is designed, the article master data gets reviewed: duplicates, inconsistent naming, variants kept as separate articles, missing attributes. Nobody sees this work, and it decides the outcome.
Shopware pays off from the point where a website builder starts to creak: many variants, prices per customer group, tiered pricing, an ERP system in the background. The effort rarely sits in the interface, almost always in the data.
No system fits everywhere. These cases speak against Shopware, and I will say so:
Before anything is designed, the article master data gets reviewed: duplicates, inconsistent naming, variants kept as separate articles, missing attributes. Nobody sees this work, and it decides the outcome.
Category structure built around what customers actually search for, not around internal product group logic. In most stores category pages are the largest untapped visibility potential.
With larger ranges, internal search is the most important sales channel. The cetrac.com relaunch used Solr-backed search for this.
Stock, prices and articles come from one source. Where data is maintained in two places it drifts apart, and that is a question of when, not whether.
If Shopware does not fit, these are the alternatives:
WordPress runs a large share of the web, and that is both a blessing and a curse: there is a plugin for every problem, and after two years the site has thirty of them, is slow and vulnerable.
Go to WordPressShopify takes hosting, payment integration, security and updates off your hands.
Go to ShopifyTYPO3 takes more effort to set up than any other system on this site, and that is not a drawback but the price for something the others cannot do: separate permissions, real language hierarchies and an editorial structure that holds up with fifty editors..
Go to TYPO3The line runs along product logic, not article count. As soon as there are customer group prices, tiers, complex variants or a leading ERP system, Shopware is the more solid base. For a manageable store alongside a content site, WooCommerce is cheaper and faster.
Two thirds of it is data work: clean up the article master data, reorder variants and categories, map images and attributes. Only then comes the technical move with URL mapping and 301 redirects so existing rankings survive. Anyone who takes the data across unexamined ends up with the old situation in a new system.
Usually yes. What matters is whether the system has an interface or at least a clean export. Where neither exists an intermediate step is needed, and that belongs before the project, not in the middle of it.
Technology is rarely the bottleneck. The schedule depends on how quickly product data, copy and images are available in usable form. Projects that drag on almost always drag at this point.
Not sure whether Shopware is the right system? Ask me, I am happy to sort it out, even if the answer is a different system.
