It depends on which monthly subscription plan you are subscribed to. The free Hobbyist plan allows up to 1,000 total products listed in your Storenvy store. The Plus plan allows up to 2,000 products, and the Pro plan allows up to 5,000. 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 of you will have to remove a product to add another, or upgrade to a plan that allows for more products.
