The document discusses different types of commissions in consignment accounting. Consignment accounting involves one person sending goods to another person to sell on their behalf, with the sender called the consignor and receiver the consignee. The consignee sells the goods and receives a commission based on sales. There are three types of commissions: ordinary commission which is a fixed percentage of gross sales; del-credere commission which is an additional commission for selling goods on credit; and special commission which is earned for selling goods above the normal price.
