Rain is a basic POS system that is good for specialty businesses. With integrated marketing capabilities, owners can stay connected with customers via social media, text, and email. Rain can handle repair and service tracking too, so that employees can access repair data right at the POS. It’s not the most intuitive interface on the market and many users find that Rain’s eCommerce offering is messy and buggy. It’s also highly reliant on Windows operating systems. However, Rain is focused on helping niche business owners. As a result, it could be a better choice than other retail or restaurant POS systems, depending on the needs of the business.
