Point of sale software is what brick-and-mortar retailers use to conduct sales in person. It’s sometimes a cash register, computer, or even a tablet where cashiers input products, tally the cost, and conduct the financial transaction. Most POS software will also communicate with inventory levels to keep everything in balance. A lot of big-box stores have wildly complex and expensive POS solutions, some of which were custom built for their needs. Independent retailers are moving away from these traditional POS systems and toward cloud-based point-of-sale solutions. There are two main types of POS software: on-premise and cloud-based. On-premise POS software requires you to be on location to use it. Terminals are the most common on-premise POS. Cloud-based POS software offers more flexibility, as you can use any connected, compatible device to access the dashboard. Cloud-based POS software is becoming more mainstream—, with an expected growth rate of more than 21.38% through 2026.
