first of all i wanted to know if there is a quotation system ?
second, why we can not configure unit price of a product in charts of account, it will be better if we can do this onlye one time on this page.
WP ERP does not have actual quotation system right now. In some cases, you may use our invoice system under Accounting if it suits you.
And unit price of a product can not be configured in chart of account. But you can manage them via our- Inventory extension (https://wperp.com/downloads/inventory/).
