Would like to create a sales invoice that incorporates the following.
Invoice for outgoings at a set percentage
The original expense may or may not have GST.
I need to create an invoice that I can show the original price paid, Strip the GST if it has it, then charge a percentage if the exGST price , total and add GST.
Will email this invoice with a copy of the original paid invoice.
I have attached screenshot as an example.
