How do I get annual turnover report from MYOB?
A solution could be going to Reports -> Accounts -> Profit and Loss -> Year to Date ->Customise, then choose a period (May to June for example), then display.
Since in some circumstances the turnover could be the same with the Gross Sales, you can also try one of the Profit & Loss Reports.
