Do you feel that your banker is holding all the cards when you are renegotiating credit lines and interest rates? According to Evanne Lorraine, you may be able to reshuffle the deck. Lorraine, controller of Daniel Smith, a $10-million art-supply company in Seattle, requests and gets from her bank a monthly analysis of her company's account, which details the bank's costs and profits by type of transaction. "You know better where there's room to negotiate interest rates and services," Lorraine says. "It's a case of 'you show me yours, and I'll show you mine.' " Not all banks will share this information, but it's certainly worth a try. Lorraine, for one, has gotten more favorable rates based on knowing the company's value to the bank.
