Final answer:
The two source documents that contain information to be entered into a business's accounting system are the Purchase order to a supplier and the Invoice to a customer.
Step-by-step explanation:
In a business accounting system, two source documents that contain information to be entered are the Purchase order to a supplier and the Invoice to a customer.
A purchase order is a document issued by a business to a supplier that confirms the details of a purchase, such as the quantity, price, and terms of the goods or services being ordered. It serves as evidence of the agreement between the buyer and the supplier.
An invoice, on the other hand, is a document issued by a business to a customer that requests payment for goods or services provided. It includes details such as the amount owed, the payment due date, and the payment terms.
Two source documents that contain information that will be entered into a business's accounting system are B Invoice to a customer and D Cheque to a supplier.
An invoice is a document issued by a seller to a buyer, detailing products or services provided, quantities, and agreed prices for products or services. It serves as a demand for payment and may also serve as proof of the transaction.
A cheque is a document that orders a bank to pay a specific amount from a person's account to the person in whose name the cheque has been issued. This serves as a record of payment made and is used in the reconciliation of accounts.
