Some important information to know when canceling an invoice:
When canceling an appointment, the invoice with a single appointment will be automatically canceled, but not the one associated with several appointments
The invoice can be canceled unless:
It contains more than one item. For example: in the case where a client had not paid for his last appointment and therefore two appointments were added to the invoice.
A payment has already been made. For example: If the customer made a payment of $5 on a $100 invoice, the invoice cannot be voided.
