Sale Purchase Price

In "Items" there are "Sale Price" and "Purchase Price"

After creating an invoice and it is marked as "Paid" the dashboard should automatically subtract the "Sale-Purchase Price" in the "Total Profit" section.

Without this, i need to manually create a "Purchase Bill" and type the purchase price again to balance out the sheets.

Kindly inform if this bug is fixable?

You should use the Double-Entry app for balance sheets:
