Invoice date

The invoice date is the date on which an invoice is issued and sent to the customer. It starts the payment period and is crucial for VAT reporting and accounting. An invoice must be issued no later than the 15th day of the month following the delivery, and the invoice date may not be manipulated to affect payment terms.
