BASIC CASH REGISTERS
For some small business ventures, all that's needed of your point of sale solution is something to count the money. You already know the prices - you just need a machine to keep track of everything. At this level there are a number of options available at very reasonable cost, many of which will have a built in receipt printer.
As your business grows, though, you will soon find the need for some more features.
Advantages of a basic cash register:
Very low cost
Simple to use
Little setup required
