An invoice is a document or notification that can be created both in electronic form and on paper. Filling in the fields of this form will create an online invoice in the form of a PDF file, which may then be printed. Both paper and electronic invoices are legally equivalent. Invoices must be issued no later than 15 days from the date of delivery of the goods or services or from the date of receipt of payment before delivery of the goods or services.
An advance invoice is a notification or payment order. This is not a tax document. Upon receipt of a deposit, users must issue an invoice or tax document pertaining to the received payment.
A credit note s a document that relates to and modifies the original invoice. This is a corrective tax document. It is issued when the delivery of goods or services is cancelled (in whole or in part) or returned (in whole or in part), or when the price is reduced. The original invoice number must be stated in the credit note. The amounts in the credit note must be negative, so the amount must be preceded by a minus sign.
The tax document for the received payment is basically an invoice. The document is issued by the VAT payer upon receipt of a payment (deposit) and before delivery of the goods or services. The tax and VAT due are calculated and shown in the document, and the invoice amount must be equal to the amount of the payment received.
You can select the listed documents in the Invoice type field in the Basic details section.
