How to Ensure Your Company Is Ready for E-Invoicing in Latvia

As Latvia’s first e-invoicing regulations take effect on 1 January, it is crucial for businesses to understand how e-invoicing works to ensure a secure and efficient exchange of e-invoices. Here’s everything you need to know to get started.

Create Your eAdrese Address

Government institutions send e-invoices exclusively to a company’s eAdrese. Additionally, some government institutions may also use eAdrese to receive e-invoices. While companies can opt for alternative channels (e.g., e-invoice operators) to exchange e-invoices, starting in 2026, some companies—particularly micro-enterprises—may choose eAdrese as their primary channel for sending and receiving e-invoices.

To enable your company to send and receive e-invoices with all other companies and government institutions, including via the eAdrese system, you must first create an eAdrese address for your organization. You can choose to use a general eAdrese or create a dedicated sub-eAdrese specifically for e-invoices. After this step, submit an application to authorize your e-invoice operator, Telema, to send and receive your e-invoices through the eAdrese system. This ensures full compliance and prepares your company for seamless e-invoice exchange.

Submitting the Application

Once the eAdrese address is created, you must submit an application to authorize Telema to send and receive e-invoices on your behalf via eAdrese.

• Preparation: Telema can prepare the application form for you.
• Signatures: Both your company and Telema need to sign the application.
• Processing Time: Applications are processed by the Valsts Digitālās Attīstības Aģentūra and may take up to two weeks.

The Power of Any-to-Any Conversion

Telema supports e-invoicing with its any-to-any conversion principle.

• Telema converts your existing invoice format (e.g., CSV, EDIFACT, ECOD, Estonian e-invoice, PEPPOL) into the required format for the recipient or channel (UBL).
• If a new standard is mandated by the government, Telema integrates it into the system without requiring changes to your ERP.

What European Law Says About E-Invoices

• UBL Format Requirement: E-invoices sent in UBL format must be accepted by the receiving company. If your ERP does not support UBL, Telema can seamlessly convert the UBL invoices into your preferred format.
• Rejection of Other Formats: Companies receiving e-invoices in UBL format can reject invoices in other formats unless alternative arrangements are made with their partners. Telema ensures all other formats are converted into UBL for compliance.
• Flexibility with Other Formats: E-invoices in other formats (e.g., EDIFACT, iDOC) are equally valid when agreed upon by both parties. Telema handles the necessary conversions, enabling smooth communication regardless of the format.

Why Avoid XML Invoices via Email?

While the Latvian government permits sending XML invoices via email, Telema does not recommend this practice. Read more here.

• Email is neither secure nor reliable for transmitting sensitive business data.
• Telema’s solutions ensure secure, compliant, and seamless e-invoice exchange, safeguarding your information and improving operational efficiency.

How E-Invoices Move in Latvia

In Latvia, the majority of e-invoices flow through operator networks such as Telema and UnifiedPost, thanks to established roaming connections. For eAdrese, Telema can handle both sending and receiving e-invoices upon application approval.

Key Differences: E-Invoice vs. EDI Invoice

The main distinction lies in how invoices are addressed:

• EDI Invoices: Addressed to a specific location, such as a warehouse or shop.
• E-Invoices: Always addressed to the legal entity.
