We found this point of sale cash register software on the web. It works very well, and is completely FREE. We
last used it to exhibit at a trade show and we just love it.
It is a complete point of sale software / cash register program that will work on any PC
computer running any version of DOS or Windows (we have it running on a laptop). It is a
DOS program, and will work with almost any receipt or regular computer printer (we use a Star TPS-100 receipt printer and a laser scanner).
It will pop open a cash drawer attached to a receipt printer or some serial cash drawers. You can use a scanner to read stock numbers.
It will track up to 13,000 different items for a medium sized retail business or with almost
no setup use in "minimal mode" for a garage sale, flea market, snack bar.
