User Posts Limit

Отличный плагин

With a little elbow grease, the possibilities are really interesting for a multisite installation, such as limiting the total number of WooCommerce products per site (regardless of the author). The plugin is not easy to learn, not very intuitive and would surely deserve to be more explicit on certain settings, however, it does the job and the author is responsive and attentive… so I recommend it 👍
