The owner of a small business is constantly running out of cash which has given him a slow pay label with his vendors. The days sales outstanding number has increased from $45$ to $65$ days and inventory turnover has decreased from $4\mathrm{.}6$ to $3\mathrm{.}0.$ Given the current conditions he has decided to get a working capital loan or seek an investor. Either one will result in a high interest rate or giving up a significant portion of the business. What suggestions would you make to help improve his cash position?
