Invoice issuance
The seller must issue an invoice for the delivery of goods or services and hand it over to the buyer. The buyer must receive the invoice and keep it immediately after leaving the business premises. For online transactions, the invoice is issued when the goods are shipped to the buyer. The buyer receives the invoice together with the ordered products.
The buyer is obliged to verify the accuracy of the information before placing the order. Objections regarding the accuracy of issued invoices submitted later will not be considered.
