What should businesses know about the technical transition to the Еuro?

On July 8, 2025, the EU Council officially approved Bulgaria’s accession to the Eurozone. This means that as of January 1, 2026, the euro will become the official currency of the country. The Law on the Introduction of the Euro in the Republic of Bulgaria, adopted back in August 2024, is now entering its practical implementation phase.

For businesses, this is not just a regulatory change – it’s an entirely new environment, affecting accounting systems, pricing, electronic payments, contracts, and internal processes. The transition to the euro requires timely and professional technical preparation. Otherwise, the risks include not only operational difficulties but also regulatory penalties.

Key Dates and Transition Milestones

Following the EU Council’s decision on July 8, 2025, a specific timeline begins, during which businesses must adapt:

August 8, 2025 – Mandatory dual price display in BGN and EUR begins. This applies to all goods and services and will continue until December 31, 2026 (Art. 30 of the law).

January 1, 2026 – The euro replaces the lev as the sole legal tender (Art. 4). All contracts, salaries, invoices, and payments will be converted using the fixed exchange rate: 1.95583 BGN for 1 EUR (Art. 12–13).

January 1–31, 2026 – A dual circulation period is in effect, during which cash payments can be made in BGN, but change must be returned in euro (Art. 17).

Until June 30, 2026 – Banks and “Bulgarian Posts” will exchange BGN to EUR free of charge.

From July 1, 2026 – Currency exchange may incur fees.

December 31, 2026 – The dual price display period ends. All systems must operate entirely in euro.

Business and the Euro: IT Adaptation

From a technological perspective, the transition to the euro requires changes on multiple levels – from data and calculations to user interfaces and external integrations.

Online Stores

E-commerce platforms must support dual price display and allow customers to clearly view prices in both BGN and EUR. Calculations for totals, discounts, and vouchers must follow the new logic. Carts and checkout pages must be redesigned to operate exclusively in euro after January 1, 2026.

API Integrations with Banks, NRA, and Suppliers

All business systems that interact with external providers, financial institutions, or government bodies must support new currency formats. This includes integrations for payments, invoice exchange, tax declarations, and financial reporting. Collaboration with external service providers is often necessary, requiring time and coordination.

ERP and Accounting Software

It is essential to ensure accurate recalculation of all values, including salaries, taxes, accruals, expenses, and depreciation. Software must be configured to work with a fixed exchange rate, with full precision to five decimal places. The transition also involves archiving BGN data for audits, comparisons, and checks.

CRM, Contracts, and Templates

Templates for quotes, contracts, invoices, and internal documents must be updated to reflect accurate euro values, clearly distinguished from BGN amounts. Many templates are automated and pull values from databases, so full compatibility with the new currency fields is essential.

Why Timing Is Critical

Technical systems do not function in isolation. Delays in preparation can cause inconsistencies across related processes such as payments, deliveries, reporting, and tax obligations.

Failure to adapt in time carries not only operational but also legal risks – including the real possibility of fines and loss of trust from clients and partners.
