Welcome to The Small-Biz Techie, a weekly series on the hottest technology trends that keep your small business running like the pros.You know when you call a really, really big company like Verizon ( VZ) or Fireman's Fund, and they miraculously know who you are and how much you owe them? Well, get this, fellow small-business owners: soon you'll be able to do just that with your own customers. Advances in high-powered productivity and sales support software for the smaller enterprise may be the single biggest revolution in small-business technology since the desktop computer. Seemingly everybody who's anybody in software -- Microsoft ( MSFT), Apple ( AAPL), Intuit ( INTU) and several start ups -- is offering new, super-powerful, super-cheap bits of code that automate lead tracking, call logging, invoicing, collections and accounting. Mark your calendars: If by the end of 2008 you're not conducting business with said management technology, one of your direct competitors will be.
