The verdict
For a small B2B team whose website is mostly marketing, with landing pages, a blog and case studies, I'd pick Webflow. It is built for that, and every B2B site I manage today runs on it. If selling products is the core of the business, I'd pick WooCommerce, because Webflow's ecommerce is fine for small catalogues but limited next to dedicated shop platforms. If you already run WordPress and want the shop inside it, WooCommerce wins easily. If nobody wants to look after updates, security and speed, lean towards Webflow, where hosting is part of the product. Do not take WooCommerce on for a brochure site. You would carry the maintenance for features you never use.
