In consignment transactions, the consignee sells goods on behalf of the consignor.
The consignee prepares a detailed statement showing:
Sales made
Expenses incurred (like freight, insurance, commission)
Amount due to the consignor
This statement is sent periodically to the consignor and is called Account Sales.
Other options:
Invoice: A bill for goods sold, issued at the time of sale.
Pro-forma invoice: Preliminary invoice sent before goods are dispatched.
Sales account: Ledger account recording sales, not a periodic statement from consignee.
