This is a program that any collector can use. You can change the input ports to whatever you need. If you collect coins, stamps, civil war relics, comic books, it doesn't matter. I have checked a lot of programs, some have too much stuff you don't use or they are too simple. This program is simple enough to be user friendly but powerful enough to use for business inventory or a knife collection. You will never find a better program for the money. If you want to try it out for 30 days go to this web site and download the program. (www.collectiblessoftware.com). If you want to make the purchase, return to my store and purchase the key that will make it work forever. You will receive all updates to the program once you have purchased it. If you have any questions email me.
