Lithuania’s Transition to SABIS for B2G E-Invoicing: What You Need to Know Preparing Your Business for the SABIS Compliance Deadline

Starting July 1, 2024, Lithuania will implement a significant change in its e-invoicing system for business-to-government (B2G) transactions. All invoices for public entities and other contracting organizations must now be submitted through the SABIS (General Account Administration Information System), replacing the previously used E. sąskaita platform. This transition is part of Lithuania’s compliance with Government Resolution No. 405 and Directive 2014/55/EU on e-invoicing in public procurement.

Key Points of the Transition

• Mandatory Use of SABIS: From July 1, 2024, the SABIS system becomes the mandatory platform for submitting e-invoices to public sector institutions. This shift aims to streamline public procurement processes, reduce bureaucracy, and enhance the accuracy and confidentiality of transactions.
• Submission Methods: Invoices can be submitted to SABIS through three primary methods:
  1. Manual Entry: Directly entering invoice details into the SABIS portal.
  2. API Integration: Integrating your accounting or ERP system with SABIS using API.
  3. Peppol Network: Using the Peppol network for cross-border e-invoicing, ensuring compliance and efficiency.
• Accepted Invoice Formats: SABIS will accept invoices in the Peppol BIS Billing 3.0 (Invoice and Credit Note) and Peppol BIS Billing CII Invoice formats, which adhere to the European standard UBL XML for streamlined VAT calculations.

Preparing for the Change

Businesses interacting with state institutions need to take the following steps to ensure a smooth transition:

1. System Reconfiguration: Companies with direct integration into the Register Center must reconfigure their systems to be compatible with SABIS.
2. Adopt Peppol Network: Utilizing the Peppol network can help automate invoicing processes, reduce errors, and improve overall efficiency. This network is particularly beneficial for cross-border transactions.
3. Testing and Validation: The SABIS TEST environment will soon be available, allowing developers to test their integrations and ensure compliance with technical specifications provided on the official SABIS website.

Benefits of the New System

The switch to SABIS and the adoption of the Peppol network offer numerous advantages:

• Automation and Efficiency: Automating invoice submissions can significantly reduce manual errors and enhance operational efficiency.
• Streamlined Processes: The use of European standard UBL XML formats simplifies VAT calculations and ensures compliance with EU directives.
• Confidentiality and Accuracy: Enhanced data security measures in SABIS ensure the confidentiality and accuracy of submitted invoices.

The transition to SABIS marks a significant step towards modernizing Lithuania’s e-Invoicing system for public procurement. By preparing for this change, businesses can ensure compliance, reduce administrative burdens, and benefit from more efficient and accurate invoicing processes. Companies should take proactive steps to adapt to the new requirements and explore the advantages of using the Peppol network to optimize their e-invoicing workflows.
