National Australia Bank and ANZ are the least popular of the big four banks in Australia as far as business customers are concerned.
AAP reports a survey of satisfaction among business customers of the four shows NAB and ANZ ranked below the Commonwealth and Westpac for every one of the past 12 months.
Commonwealth and Westpac finished the financial year with average business customer satisfaction ratings of 7.4 and 7.3 out of ten, respectively.
By comparison, ANZ and NAB both had an average satisfaction rating of 7.0 in June.
DBM Consultants managing director Dhruba Gupta said Westpac and the Commonwealth had done a better job of keeping their customers happy.
"While all financial institutions have heavily invested in delivering improved customer service, business decision makers have consistently rated Westpac and the Commonwealth Bank highest," Mr Gupta said.
