Whether you run a retail store with a constantly rotating stock or a service business like a salon or tattoo parlor, an inventory management system can help. Imagine pulling out your tattoo machine only to realize you're out of the color red. That can seriously limit your design options. What about running out of 30 volume developer at a salon? Sure, you can probably blend a mix of 20 and 40 volume to handle color, but the result won't be the same. With an inventory management system that’s part of your credit card processing system, you never need to worry about missing product.
