Custom Report for commission

hi,

Can you help me create a custom report for Commission in monthly basis?
A comparative on monthly basis and totals at the end?
I have created commission on special account

What’s your calculation method for commission? You probably want to create a custom field on sales invoice (or receipt) level to capture who is earning the commission. Then you can use Advanced Query to select all transactions for the month and group them by custom field which will give you monthly total per custom field.
