ANZ lifts business customer satisfaction ANZ has lifted its standing among business customers in recent months, while rival National Australia Bank remains at the bottom of the pack among the big four banks. A monthly survey of satisfaction among the big four's business clients shows ANZ, which has lagged alongside NAB for the past year, had improved its average rating in the past two months. ANZ had an average satisfaction rating of 7.2 out of 10 in October, closing the gap on the Commonwealth Bank, which averaged 7.5 and Westpac, which scored 7.4, according to the DBM Consultants' Business Financial Services Monitor (BFSM). Meanwhile NAB continued to trail its rivals with an average rating of 7.0, despite being the country's biggest business bank. DBM Director Maria Claridad said the increase in ANZ's rating had come mostly from micro businesses, which have an annual turnover of less than $1 million. "Micro businesses reported the greatest increase in satisfaction, with ANZ up by 0.4 points in the past six months," Ms Claridad said. The BFSM is based on interviews with 20,000 businesses a year.
