Frenzo Furniture Co. is a manufacturer of specialty furniture, and uses the contract-based approach for revenue recognition. Because each piece of furniture is custom manufactured, the company requires a contract prior to beginning the production process. Contract terms include a payment of 40% of the estimated cost of the finished piece before production begins. Frenzo Furniture Co. should record the collection as a credit to sales revenue. credit to unearned revenue. credit to inventory. credit to cost of goods sold.
