Preparing an e-invoice is half the job — it also has to reach the recipient through an accepted channel. Latvia allows three, and the choice mostly depends on how many invoices you issue per month.
1. E-adrese on Latvija.gov.lv — free
The official electronic address is a state-provided channel and costs nothing. You need an activated e-adrese account for the company and a secure identification means (eParaksts, Smart-ID or internet banking). Each invoice is handled separately, with no accounting integration, so it suits low volumes.
2. An e-invoicing operator / Peppol provider — paid
The operator connects you to the Peppol exchange network, so invoices reach recipients whatever system they use, usually with integration into your own software. Pricing typically follows volume.
3. A direct arrangement
The law allows the issuer and recipient to agree their own exchange channel, such as a direct system integration.
Which to choose
Few invoices a month: the e-adrese is enough — and until 2028 B2B e-invoicing is not mandatory for you anyway. Dozens a month or an accounting system: an operator with integration. See e-invoicing in Latvia for the deadlines.
