The countdown to 2000 continues. Are your business's computer systems in order, ready for the millennium? Chances are yes, according to a nationwide survey conducted by Irvine, California-based Sage Software Inc. (http://www.sage.com). In May, Sage found that 55 percent of the small businesses it polled had already ironed out any potential Y2K problems in their systems, and another 38 percent were working on the problem. So if you haven't yet tackled Y2K, you can rest even uneasier, knowing your competitors probably already have. The average amount being spent on such work: $16,600 per business, including the costs of internal and external employees, software and hardware fixes, and overall company support. Says Dave Butler, Sage Software president and COO, "It appears that Y2K repair costs, once expected to cripple the small-business market, are being kept in check." Let's hope so.
