There is no accounting entry recorded in a company’s general ledger accounts when an order is received.
The reason is that a sale or sales revenues has not yet occurred, nor does the company have an accounts receivable at this point. Generally, the sale and the related receivable occur when the goods are shipped (FOB shipping point) or when the goods are received by the customer (FOB destination).
While there is no accounting entry in the general ledger, it is likely that the company will create a record outside of the general ledger to track the order and to schedule various activities that will be needed to ship the products to the customer.
