The person I built the site for wants a feature that lets them manually upload invoices. It will appear as an “Invoice” button in the Orders section. Do you happen to know of any plugins like that? The ones I’ve found all generate invoices automatically, but I want to be able to add them manually.
Unfortunately, there is no such option by default in WoodMart and WooCommerce. You need to find a third-party plugin to achieve more functionality that best suits you.
