First of all, consider how much you are ready to spend for increased efficiency, better usability, improved reporting or anything else you are looking for. Fixing a budget in advance increases the range of Shopify apps you can choose from. The app's price depends mainly on whether it is a custom-built app for a Shopify user or a public app for the App Store. Besides, it also depends on tasks it is used for like inventory, marketing, finances, sales, customer support etc., as well as its impact on the business result and processes. So, compare pricing plans, consider the full app pricing, take a look at any additional costs related to implementation or use.
