Need Previous Balance on Invoices

Hi guys
I need to show the outstanding Previous balance on all invoices of Purchase or Sale. How can I add this to the invoices?

I’ll be much obliged for this help.



Look into reports. Such as Supplier Statements (Unpaid Invoices) and Customer Statements (Unpaid Invoices)

Also read the many, many other threads on this topic on the forum. I am closing this topic because it is redundant. Please continue discussion in an existing topic.
