Selling high quality meats and cheeses at below average prices, getting customers in and out quickly and bolstering business with a small soup and/or sandwich counter on the side is what makes a deli different than the meats section of a super market or a butcher.
Delis are known for providing fast and friendly service. Deli POS software should as well.
The qualities that make delis unique are the same that make point of sale software and systems different than a standard retail cash register: customization. Deli POS systems also further minimize the amount of time customers are required to spend making purchases.
