It depends on which monthly subscription plan you are subscribed to. The Free plan allows up to 20 total products listed in your Storenvy store. The Artisan plan allows up to 100 products, the Growth plan allows up to 500 products, and the Professional plan allows up to 5,000 products. This does include retired, coming soon, and active products. This does not include variations (such as color or size) that you have created within products. If you reach your combined total product limit you will have to remove a product to add another, or upgrade to a plan that allows for more products.
