How to deal with one product with over 100 variants

For example, a v-neck t-shirt would have a combination of over 100 variants for sizes and colors. What are some ways to work with the inventory and easily monitor the variants on our site? I have seen that there are some apps that can provide more than 100 variants list, but does this only allow exceeding the 100 cap? Any help/suggestion would be appreciated.

Using an app would be the only way to surpass the 100 variant limit if you can’t split the product into two. You’d be looking to use a product options app to set the product up. There are a number of options available that vary in price and features. Are you needing an app that does more than allowing you to exceed the 100 variant limit?
