One of my clients has a sortiment of 200+ articles, each one of them is in 5 different sizes available. Which platform should I choose for the webdesign? Since he has no clue about coding, but wants to update his website, I would prefer wordpress, but I am not sure whether the sites speed will be too slow with WP and such an amount of pages / sites. Before he had Magento and was not satisfied, for example he had to create an own page for each size of an article, so basicly you would have 5 pages for each article (because of 5 diff. sizes / product). Is this the same with WP or html or can the different sizes be stored on 1 page / site? Also, the site must be compatible with the software Lexware, so that after 1 customer purchases, the owner will receive the invoice and the clients informations, which should be editable. I would really appreciate your advice on this, because I have never set up such a website.
