We appreciate you sharing your idea with us regarding combining two reports into one and displaying three money columns in MYOB Business Pro.
While it's not currently possible to directly merge two reports into one within the software, your suggestion has been noted on our ideas board. Our development team regularly monitors this board for valuable feedback like yours to enhance the functionality of our software.
In the meantime, a possible workaround would be to export the three reports separately into Excel and manually edit to combine them.
Feel free to create a post again if you have any suggestions or if you need further assistance.
