Everything we have looked at in this chapter is fairly non-technical. But the huge range of options and features you have at your disposal can sometimes cause apparent complexity. It is well worth playing with the PrestaShop catalog options, and perhaps, re-reading this chapter so that you can fully grasp how PrestaShop manages your catalog and how incredibly flexible and diverse it is.
Having said that, don't hold back on further development until everything is perfect. Any e-commerce store should be an ongoing cyclical thing that you constantly add to, improve, and refine. Also, don't forget my suggestion about opening your shop with just a core range of products and then adding more on an ongoing basis. If you can be making money while working on your catalog, then I think it makes sense.
