Hi WMGLNZ,
Thank you for your response.
In MYOB Business/Essentials, you can only split a payment transaction. It's not possible to split the item into two different accounts when you create a bill. However, it is possible to add another line with the desired account without entering the item ID, which I appreciate you sharing.
Thank you for updating this post, as this will also help other users who might have the same concern.
Please feel free to create a new post if you need help in the future. I'd be delighted to assist you.
Cheers,
Princess
