The best thing about spark shipping for me personally was being able to see my sales in real time! I can easily track how many orders have been shipped as well as what percentage of items sold are still available at this point. It's not very easy to use if you're new or don't know much coding but it does get easier once you figure out some things like inventory management which isn't too difficult either (you just need lots of patience). You also cannot do any customization when creating an account so make sure there aren't other features that will be helpful before signing up because they won't let you change anything after creation unless its something super specific. We were looking into different ways we could ship our products without having employees physically handle them all day long since most people these days work from home fulltime anyways. This has allowed us to.
