A cash register will help you count your money. If someone purchases an item you will be able to ring that item up and receive their cash. The more basic a Point of Sale system the closer to a cash register it will be. Without the proper training and customizations, an expensive Point of Sale system can become an overpriced cash register.
A point of sale system will be able to tell you not only how much was spent, but how much of that was profit and give you vital reporting features to be able to drill down into how profitable your store is, predicting trends and giving you the data you need to invest in inventory that will turn the highest profits.
