Final answer:
When a company pays an invoice within the discount period, they need to pay the discounted amount stated on the invoice.
Step-by-step explanation:
When a company pays an invoice within the discount period, the amount of cash required for the payment is the discounted amount stated on the invoice. The discounted amount is lower than the original amount due and is calculated based on the agreed-upon discount terms. For example, if the original amount due is $100 and the discount rate is 10%, the discounted amount would be $90.
