Hi,
How can we give discount as fixed amount .? right now we can able to give % discount for each and every item.
For example i want to give discount 150 to a sales invoice of total 500. you should give an option as percent and fixed amount so that we can put the discount amount easily
Right now, WP ERP does not have a fixed amount option in discount (Accounting -> Invoice).
So in this case, you will need to make changes in the core of WP ERP.
