Jaslene received a bill from her supplier that included more than the actual products purchased. What might the charges be for and what should she do$?$

This can happen with the FIFO inventory method. It just means the items she ordered have different costs, based on when the supplier purchased them on their end.

It could be an error. She should contact the supplier to discuss and request a new bill.

It is likely for delivery or shipping charges. She should add the charge to the purchase transaction in QuickBooks.
