Point of Sale (POS) Application

[eluser]thurting[/eluser]
This is a serious undertaking. If you really plan on offering a web based POS application, you will need feature packed software, advanced technical support, and numerous servers running across multiple data centers. Things like hardware integration are not features that you should 'eventually' be looking at, but are absolutely necessary to make your application at all practical. Based on some of the comments you have made I don't know if you have really thought things through. I'm not saying don't do it, and I do wish you luck, but something like this really requires a large team and a fair amount of start up capital. I don't know your situation, but it may not be the most prudent business decision, especially considering an already crowded market. Unless you have come up with a new technology or feature that will greatly increase efficiency at the register, I just don't think it is worth the time.
