Sending Pro-Forma Invoice to Customer
                        
                            The pro-forma invoice is a document that is mostly used as an essential receipt
                            with quotation. It is used with quotations before product delivery. This ensures
                            the type and quantity of the product, their esteem, and other significant data like
                            example, weight and transportation charges. The pro-forma invoice is different from
                            a typical invoice.
                        
                            You can trigger an action by
                        
                            Go to SALES > Configuration > Settings and activate the Pro-Forma Invoice feature.
                        
                             
                        
                        
                            Send a pro-forma invoice
                        
                            A pro-forma invoice can be sent from any quotation or sales order.
                        
                             
                        
                             
                        
                        
                            Lock confirmed sales
                        
                            You can lock a sale order when it is confirmed. This prevents any altering of the
                            order.
                        
                            This can be activated by
                        
                            go to Sales > Configuration > Settings and activate the Lock Confirmed Sales feature
                        
                        
                             
                        
                        
                            Lock an order
                        
                            After activating lock feature the status of the order will be changed to Locked.
                        
                             
                        
                        
                            Sale order can however, be unlocked by clicking the UNLOCK button.
                        
                             
                        
                        
                            Sales warnings
                        
                            The Sale Warnings feature helps to generate alert messages or blocking messages
                            on buy orders. This depends on the merchant or an item.
                        
                        
                            For example, if you frequently experience any issue with a merchant you have to
                            raise an alert message. Besides, an alert can be raised or a block message can be
                            raised when an order is to be suspended.
                        
                            You can activate this feature by going to Sales> Configuration>Settings. Activate
                            the option Sales Warnings under Quotations &Orders.
                        
                             
                        
                        
                            Add a warning on a vendor
                        
                            While activating the warnings feature, you get an alternative under the Internal
                            Notes tab on merchants. Here, you can choose to compose a basic cautioning or a
                            blocking message.
                        
                             
                        
                        
                            Add a warning on a product
                        
                            Another option you get under the sales tab on the product page is that you can include
                            a notice or a blocking message.
                        
                             
                        
                        
                            A message will be raised in the event when you attempt to approve a Purchase Order
                            from a seller or with an item with a notice. This can be disregarded by clicking
                            OK.
