When you are looking to install a new POS software system for your business, you may be wondering what the best features are. While the answer to that question will differ depending on the type of business you own, there are some things to consider before you make the final decision. Pricing: POS software plans can range anywhere from free to $150 a month. If you have a large business, you might need to pay a bit more. Keep in mind that processing fees will range from 1.5% to 3.5% per transaction, so you'll want to take your time and decide how much you're willing to spend before making the purchase. However, once you've decided on your budget, you can begin your search for POS software.
