I'm looking to bring my 18th century business to the 21st century. I own a fabric store and all i have as of now is the fabric, item numbers, and ADT security can any one give me a list of item i would need to bring a new business to the 21st century. I have a very old register, but I would like something that might connect to my computer and keep count of my inventory. Prices would help to I'am not to sure how much these updates would cost.
