The invoice is a document that provides detailed information related to the quantity, type, and price of goods or services agreed by both parties (seller and buyer) from the seller to the buyer. An invoice is attached to the sales order to complete the sales flow. Every invoice has a sales order in it that may contain multiple orders. An invoice can be created without a sales order but to create a sales order invoice is essential.
Once the user creates an invoice for an order, all the work involved in creating a sales order is done. The inventory will update instantaneously without a sales order in case of a direct invoice. It allows you to add more items in an invoice that comes under the category of ‘’ directly invoice items’’. However, you cannot add more items during or after the ‘’invoice’’ attached. The invoice will be sent to the customer through email. It will be an automatic email generated by the system to send on the given information.
