Invoicing in Bulgaria

What is an Invoice

The invoice is a commercial document issued by a seller to a buyer, showing the subject of the transaction – a good or service, the quantity and the agreed price for the products or services that the seller has already provided to the buyer. The invoice shows that the buyer owes payment to the seller according to the method of payment. From the seller’s point of view, the invoice is a sales invoice. From the buyer’s point of view, the invoice is a purchase invoice.
