Key Components of an Invoice

Which of the following is NOT typically included in a standard invoice?

A Customer's payment history

B Description of goods or services

C Total amount due

D Invoice number

💡 Hint

Consider what information is necessary to request payment versus customer records.

An invoice usually includes an invoice number, description of goods or services, and total amount due. Customer's payment history is not part of the invoice but kept separately.

Calculating Total Invoice Amount with Tax

You have an invoice with a subtotal of $200 and a sales tax rate of 8%. What is the total amount due on the invoice?

A $192

B $208

C $216

D $220

💡 Hint

Calculate tax by multiplying subtotal by tax rate, then add to subtotal.

Sales tax = 8% of $200 = $16. Total = $200 + $16 = $216.

Identifying Errors in an Invoice

An invoice lists 10 items at $15 each but shows a total of $140. What is the error in this invoice?

A The total should be $150, so the invoice total is incorrect

B The price per item is wrong; it should be $14

C The number of items is incorrect; it should be 9

D There is no error; the total is correct

💡 Hint

Multiply the number of items by the price per item to find the correct total.

10 items × $15 = $150. The invoice shows $140, which is $10 less than it should be, indicating an error in the total amount.

Choosing the Best Invoice Payment Terms

A company wants to encourage faster payments from customers. Which payment term is most likely to achieve this goal?

A "Net 30" (payment due in 30 days)

B "End of month" (payment due at the end of the current month)

C "Net 60" (payment due in 60 days)

D "Due on receipt" (payment due immediately upon receiving invoice)

💡 Hint

Consider which term requires payment the soonest.

"Due on receipt" means payment is expected immediately, encouraging faster payment compared to longer terms like Net 30 or Net 60.
