A seller / service provider can specify accounting entries (account numbers and amounts).

An electronic invoice.

It is an invoice, prepared using a computer and stored electronically. For example, a seller of goods or a service provider, using a computer prepares an invoice and sends it to e-mail of a buyer / recipient of services. The invoice is not of a printed form. After sending, the invoice is stored in a computer, in electronic form. Both parties must be able to print such invoice.
An electronic invoice must comply with the above mentioned requirements, except the signature.

If an invoice is prepared in electronic form (with computer), then the invoice must sign with the electronic signature (for example, using eparaksts.lv).
A person, issuing invoice and a recipient of the invoice can agree on signing electronic documents with such electronic signature, which is not a secure electronic signature. Both parties can create electronic data and agree that the electronic data will be used as an electronic signature. But such an agreement must be in written form and personally signed, or in electronic form and signed with the secure electronic signature.
According to article 7.1 of the Accounting Law, an invoice (without signature), received from other persons, can be used as source document in following cases:
  • If a transaction, specified in particular invoice, is confirmed by another external document (received from other persons) and this external document has legal force. For example, parties enter into a contract for a sale of goods, a seller issues an invoice, a buyer pays the invoice.
    In such case, additionally to the invoice, exists bank document (proof of payment) and also sale - purchase agreement.
  • If it is impossible to fulfill the above requirement (it is impossible to obtain another external document confirming the transaction), then the responsible person of the enterprise can confirm the transaction in accordance with the procedure established by a head of the enterprise. A head of an enterprise approves the procedure (instruction), according to which the transactions are confirmed, also a head of an enterprise appoints (approves) persons who have the right to confirm the transactions.
    For example, an enterprise downloaded (purchased) a program on the Internet, received an invoice, but the invoice is not yet paid (the payment will be during the next month). In this case, the only document is an invoice, and the responsible person of the enterprise confirms that the transaction was made.

Additional details for the value-added tax (VAT) invoice.

The details are listed in 125 and the following articles of the Law on Value Added Tax.
In most cases, additional details are as follows:
  • Order number of one or more series. Order number uniquely identifies an invoice. The head of an enterprise in the accounting organizational documents provides the conditions for the creation of order number.
  • VAT number of a seller of goods / service provider.
  • VAT number (if any) of a buyer / recipient of services.
  • The date of delivery of goods / services or the date when payment is received in advance, if the date differs from invoicing date.
  • VAT rate (for example, 21%, 12%, 0%).
  • If for the transaction must apply non standard VAT rate (not 21%), then must write basis for application non standard rate (reference to the article of the law).
  • Additional information in relation to certain types of transactions. For example, in case if the goods are delivered / services are provided to a person with the VAT number of another country of the European Union. Also, in case of construction services, the supply of mobile phones, tablet computers, etc.
