i'm using quickbooks pro for my auto repair and towing business. my residence is on the premises, and swmbo will keep the books and spend most of her time in the house. i have an office attached to the shop and i would like for us both to be able to use quickbooks. i'll use it to create invoices and keep parts inventory, while she'll pay bills, enter payments, etc. trying to work separately during the day and updating at the end of the day seems like it could turn into a nightmare. is it possible to network the two computers together without paying a fortune to computer services company? both of my computers have network cards, as i previously had them connected to a router in order to share my cable modem. would a wireless router reach about 50 feet from the house to inside the office? i've got windows xp home on one computer, while the other is windows 98. i'm not opposed to upgrading the other to xp, or upgrading both of them to something else. i have above average computer skills, but i'm far from an expert. is trying to do this myself a realistic task?
