B2B e-invoicing in Latvia
Businesses are not currently obligated to send and receive invoices electronically when dealing with other businesses. However, as per the amendment to the Law on Accounting, a mandate is on the way.
While mandatory B2B e-invoicing will not take effect until 1 January 2028, businesses can submit B2B e-invoices to the eAddress system voluntarily starting from 30 March 2026. If they choose to issue e-invoices, the issuer must ensure the integrity of the content and the authenticity of the origin by, for example, using an electronic signature.
A B2B e-invoicing mandate has been in development for years and has been subject to several postponements. Most recently, in June 2025, the commencement date of the obligation was delayed from 1 January 2026 to 1 January 2028.
