I am new to this company and new to QB. Before I started, we sold $45k to a customer but did not have them set up correctly in our system for sales tax, so sales tax was not charged or collected. The invoice was from August, so I cannot go in and modify the invoice now because the period is closed.
How do I charge the customer the $2,531.28 they owe in tax? Can I create a new invoice for tax only to collect now in October?
