Ram Katalan, president and co-founder of NorthStar Moving Corp. in Chatsworth, uses business credit cards but is frustrated that interest rates on them rose to as much as 19% during the recession. He said he has been unable to negotiate lower rates or higher credit limits. Katalan uses his cards up to their limits to pay expenses such as hotel bills for his movers, rather than give his employees cash, then he pays the full balance, or close to it, “just to use them again the following month. It’s more of a cash card than a credit card,” Katalan said.
