as great as these are the program needs to do all of the above in one program intergrated or multiple that work at an instant and its more or less like a small business software these links are very helpful i just want something that can function solely for the scanning of bar codes and credit cards and manage database things like students names and the money they owe or money they pay for there weapons or clothing and how many times they have gone to class in a week. Karoshi is awesome but it does only part of what i need for my dojo. so if there is any thing else then thanks any way for the help. i was also wondering whats out there for winxp i looked on the download.com site and foun a small business section and saw some nice stuff there but i may need to talk to a local business and ask them what they use. its not to compete in the market as a school its so they can keep functioning as a workable dojo. money management and things like that so they can maximize every dollar. they don't make to much there so being as efficient as possible would benefit them.
