Based on the European Directive 2014/55/EU, Bulgaria has legislated the use of e-invoicing in public administrations to receive and process electronic invoices. However, it has yet to implement a mandate for sending invoices electronically.
When it comes to electronic invoicing, every country has its own rules and requirements. This is your ideal overview of Bulgaria e-invoicing.
E-invoicing is voluntary for business-to-business transactions in Bulgaria. Consent from the buyer must be obtained before the seller can issue an invoice electronically.
The following methods are accepted for ensuring the integrity and authenticity of electronic invoices:
Business Controls Audit Trail
Electronic Data Interchange (EDI) or Qualified Electronic Signature
Invoices must be stored in a way that guarantees their integrity, authenticity, and availability during the five-year required storage period.
B2G e-invoicing in Bulgaria
While governmental bodies must be able to accept and process e-invoices, their suppliers are not required to issue invoices electronically. That means there is no full B2G e-invoicing mandate in Bulgaria.
The Central Automated Information System for Electronic Public Procurement (CAIS EPP) is Bulgaria’s official e-invoicing platform for B2G transactions.
Timeline of e-invoicing adoption in Bulgaria
The key dates in Bulgaria’s e-invoicing efforts are as follows.
1 November 2019: Contracting authorities are required to accept and process e-invoices for public procurement contracts
2021: The National Revenue Agency consults with industry stakeholders about implementing an e-invoicing mandate
9 December 2024: The draft State Budget Act introduces mandatory SAF-T reporting requirements, starting from 2026

We’re excited to announce Sovos as a proud exhibitor at the Accounting Summit 2025, taking place this September in Düsseldorf. This event brings together leading innovators and decision-makers in accounting, finance, and tax to explore the digital transformation shaping tomorrow’s financial landscape.
Our very own Christiaan Van Der Valk, General Manager Indirect TaxTech & VP Regulatory, will join the conversation with a session titled:
Decoupling Strategy for Strength: One Compliance Platform, Flexible Automation.
Session Overview:
As governments worldwide increasingly base enforcement strategies on real-time transaction data, companies must rethink how they approach compliance and automation. In this session, Christiaan will explore how organizations can strengthen resilience and agility by building modular, future-proof compliance frameworks, designed for a world where Mirror Visibility is no longer optional.
This session will cover:
Truth in the transaction: How governments are turning real-life transaction data and continuous observation of economic operations into the backbone of enforcement strategies.
Mirror visibility: Why businesses must be able to see what tax administrations see, ensuring control in an environment where every transaction is monitored.
Modular future: How to reimagine automation as composable modules, seamlessly integrated with local compliance functionality, with agentic AI acting as the “super-glue” of tomorrow’s workflows.
Attendees will walk away with a clear vision for building compliance strategies that balance centralization with flexibility, while staying fully aligned with ever-changing regulatory landscapes.
We look forward to connecting with industry peers and exploring the future of compliance, automation, and digital accounting in Düsseldorf!
2025 will be a pivotal year for tax compliance, with governments accelerating e-invoicing mandates, SAF-T requirements and VAT reforms. In this Sovos webinar, Réka Hall, Senior VAT Consultant, will break down the latest updates — from Bulgaria’s SAF-T schema to new mandates across Europe, the Middle East and beyond. Gain clear, actionable guidance to stay compliant, avoid costly errors and future-proof your processes.
As the IRS rolls out Form 1099-DA for digital asset transactions, financial institutions that have long reported on traditional securities through Forms 1099-B, 1099-DIV, and others are encountering a new level of complexity. For firms expanding from traditional finance into digital assets, it is essential to understand both the differences and the overlaps between these reporting frameworks. Join Sovos experts as we break down the specific requirements of 1099-DA reporting, from capturing transaction data to calculating cost basis, and compare them with established reporting processes for stocks, bonds, and other traditional instruments. We will also address the risks of treating digital asset reporting as a separate process (spoiler alert – data silos, inconsistent outputs, and operational strain!) Attendees will walk away with strategies for unifying reporting across asset classes. If you want to ensure accuracy and compliance and deliver a seamless customer experience, you don’t want to miss this.
As your business grows across borders, VAT compliance can quickly become a challenge. In this session, Sovos’ VAT Consultant Michail Konstantinou will break down the essentials of cross-border VAT, from knowing when and where to register to managing non-resident VAT and reclaiming it across multiple jurisdictions.
You’ll gain practical insights into:
Import VAT rules
Intra-EU trade requirements
Refund processes, including local returns, EU portals and the 13th Directive
We’ll also explore how the right technology can streamline compliance, strengthen audit readiness and reduce manual work — so you can focus on growth.
Whether you’re preparing for your first European market entry or managing rapid international expansion, this webinar will equip you with strategies to stay compliant and maximise VAT recovery.
On 6th August, following multiple consultations throughout 2024 and 2025, the Polish government passed new legislation and updated schemas for its National e-Invoicing System (KSeF). The timeline and criteria for mandatory compliance have been clearly defined under the updated legislation of KSeF 2.0, meaning organisations may have as little as 6 months to prepare.

With the pilot phase of France’s e-invoicing reform fast approaching, we’re prepared to support businesses every step of the way. As a global provider of tax compliance solutions and a trusted technology partner, we’re ready to help companies navigate the upcoming transition with confidence.
Preparing for a Milestone Year
The French B2B e-invoicing reform is set to begin its pilot phase in February 2026, and we’re fully prepared to support companies during this critical stage.
With less than a year to go before the phased implementation of the mandate, we’re anticipating the needs of both French and international businesses operating in France. Our solution is complete, interoperable, and aligned with the latest specifications published by the French tax authority (DGFiP) and the AFNOR Commission.
A Pilot Phase Starting in February 2026
According to Article 91 of the 2024 Finance Law, the obligation to receive electronic invoices will apply to all VAT-registered businesses from 1 September 2026. The issuance of e-invoices and e-reporting data will be introduced progressively between 2026 and 2027.
To help companies prepare, the French tax authority has announced a pilot phase starting in February 2026. Participation will be voluntary and will involve testing all end-to-end flows, formats, and business scenarios set out in the reform. Companies and their Partner Dematerialisation Platforms (PDPs) will play a central role in ensuring everything is operational before the full mandate kicks in.
We’re Operational and Ready to Cover 100% of the Use Cases
We’re committed and ready to support our clients and partners in this next crucial step. Our solution enables participation in the pilot while covering all 36 use cases identified by the DGFiP, including:
Issuing and receiving invoices in all required formats and profiles (Factur-X, UBL, CII – EN16931 and ‘Extended’)
Exchanging invoices either via the public invoicing portal (PPF) or between PDPs using the PEPPOL network (adapted to French requirements)
Collecting and transmitting e-reporting data (B2C transactions, cross-border B2B transactions, payment data) to the PPF on time and accurately
Managing data and workflows related to specific business scenarios defined by the DGFiP and now formalised in the AFNOR XP Z12-014 standard, such as SIREN numbers, multiple delivery addresses, detailed VAT mentions, and internal accounting processes
Our platform is fully compliant with the latest technical specifications issued by the DGFiP, and we plan to support our first voluntary clients from the very beginning of the pilot in early 2026.
As of August 2024, we’re officially registered as a Partner Dematerialisation Platform (PDP no. 0004). Thanks to our deep regulatory expertise, strong local presence, and robust global infrastructure, we’re uniquely positioned to support clients not only during the pilot, but all the way through full implementation.
Guiding You Through the Transition with Confidence
This combination of technology, expertise, and trusted partnership makes Sovos a strategic ally in the transition to e-invoicing. We’re here to guide businesses of all sizes with confidence, ensuring full compliance with the evolving requirements in France, across Europe, and around the world.
From Europe to Southeast Asia, governments are reshaping e-invoicing rules and timelines, putting pressure on businesses to adapt. We will break down the latest changes across these key jurisdictions.
With the VAT in the Digital Age (ViDA) officially adopted by the EU on 11 March 2025, businesses have many questions about its rollout and impact on their operations. We answer the most frequently asked questions.
When will businesses begin to see an impact from ViDA?
ViDA is leading to changes in several areas of Value Added tax (VAT) law, starting now and going on for the coming decade.
From its entry into force on 14 April 2025, ViDA immediately removed restrictions that previously prevented EU countries from introducing mandatory domestic e-invoicing.
Therefore, Member States can now introduce both mandatory domestic e-invoicing and digital reporting requirements (DRRs), as long as they align with ViDA by 2030. By 2030 electronic invoicing and DRRs will become mandatory for so-called intra-Community transactions.
Since ViDA’s approval, we are already seeing momentum across the EU, with several countries announcing plans to introduce mandatory e-invoicing and real-time reporting within the next few years. ViDA will see the intensification of the current wave of new Continuous Transaction Control (CTC) mandates to prepare for in the short term, with many EU countries already announcing initiatives or starting rollout.
Is there likely to be a grace period for businesses to adjust and comply?
No, the ‘grace’ period for businesses was taken into account when setting the 2030 deadline for mandatory electronic invoicing and DRRs for intra-Community transactions. Member States’ domestic mandates will follow each country’s legislative process and culture but we are seeing an average period of 18-24 months for businesses to adapt, with no grace period after that.
Many businesses gravely underestimate the work required to ensure data quality, including the long adaptation cycles for their different business applications to incorporate the data and process changes required for real-time reporting and e-invoicing.
The introduction of changes of this magnitude to business and administrative processes is never without challenges on both sides of the equation. Businesses will make mistakes that may take time to fix, and this only gets harder as governments do the same thing in parallel under the pressure of political deadlines.
What business processes are likely to be impacted as part of the new regulations?
All invoicing and related processes will be impacted by ViDA including any accounts payable and accounts receivable process and the associated information systems that support them. All invoicing needs to be reviewed against this backdrop and readied for the digitization paradigm shift that will come off the back of ViDA.
How is ViDA likely to impact my business?
Whilst the reporting processes required to meet specific transmission protocols, authentication, and document exchange orchestration tend to get a lot of attention, businesses should be equally wary of the impact of CTC mandates generated or modified by ViDA on their upstream processes and data.
Many businesses have multiple ERP systems, multiple billing systems, accounts payable systems etc. for different lines of business or trading partner categories. Most of these systems process invoice data on a paper or PDF invoice manually or semi-automated which cannot be easily ‘upgraded’ to handle the data completeness and quality requirements of a stringent e-invoicing and e-reporting regime.
Beyond the headlines about mandatory e-invoicing and real-time reporting, the fine print of ViDA will drive a number of challenging modifications to business processes. This includes the very definition of what constitutes an invoice which will require billions of PDF invoices in the European Union to be converted to machine-readable formats.
To comply with ViDA, businesses will need to increasingly use software and service providers that can guarantee compliance with frameworks and laws that add up to a need for a complete rethink of invoicing processes and systems throughout most businesses.
Can businesses expect their current technology partnership to work for the new standards?
Companies that currently use EDI systems, procure-to-pay or accounts payable automation software of SaaS services, customer communications management, order-to-cash, electronic billing presentment and payment solutions etc. must ask themselves how those platforms will handle the new requirements for e-invoicing and e-reporting under ViDA and associated regulatory initiatives.
These vendors specializing in business process optimization typically have little experience with this specific area of compliance. Most of them are not set up to anticipate and address the tens or hundreds of changes that typically follow the initial rollout of a CTC regime in any jurisdiction in a timely manner.
We advise businesses to contact their enterprise software vendors and service providers now to ask these questions – are they aware of these changes as a result of ViDA, and what is their plan to keep you compliant?
How will cross-border transactions be impacted?
Under ViDA, cross-border transactions between EU countries will be subject to a new real-time reporting regime (DRR) that replaces the current requirement for a recapitulative statement. Each transaction will be reported individually to the respective national tax authority, which will then transmit the data within one day to a centralized European Commission-managed system known as “Central VIES”. This enhanced platform, launching in July 2030, will consolidate intra-EU B2B transaction data, integrate with systems like the Customs Surveillance System and the Central Electronic System of Payments (CESOP), and provide a unified interface for VAT number validation and transaction transparency across the EU.
In addition to these digital reporting sections of ViDA, intra-EU cross-border transactions are also affected by other parts of the proposal in other ways. For example, quite far-reaching changes will take place, removing administrative burdens for businesses moving their own stock between EU countries.

Czech Republic E-invoicing
Like many countries, the Czech Republic has experience with e-invoices for the purposes of reducing administrative strain, reducing associated costs and greater visibility into the nation’s transactions.
It has yet to implement a full mandate on electronic invoicing for any type of transaction. This could change quickly, however. Keep this page in your bookmarks to stay on top of the country’s e-invoicing plans.
There is no mandate for issuing electronic invoices for B2B transactions in the Czech Republic, nor have any plans been unveiled for the eventual implementation of a B2B e-invoicing mandate.
Issuing e-invoices is optional, but a supplier must acquire the buyer’s consent before legally transmitting an invoice electronically.
B2G e-invoicing in the Czech Republic
There is no blanket mandate covering B2G transactions in the Czech Republic.
Central, regional and local authorities must accept and process e-invoices if they meet the format according to the European Standard. That said, suppliers are not required to issue e-invoices.
These authorities are also obliged to use the Národní elektronický nástroj (NEN) platform as part of the e-procurement process unless they have been authorised to use another tool.
Timeline of e-invoicing adoption in the Czech Republic
These are the dates to know in the Czech Republic’s e-invoicing journey.
August 2015: The Národní elektronický nástroj (NEN) platform is launched to replace the Public Procurement and Concessions Portal (Portál VZ)
1 October 2016: Public contracting authorities must accept e-invoices if they meet the European standard for formatting
April 2019: Public authorities must be able to receive and process e-invoices for B2G transactions
Setting up e-invoicing in the Czech Republic
If you fall within the Czech Republic’s remit for issuing e-invoices, it’s wise to choose a partner that can help – not just in this country, but everywhere you do business.
That’s where Sovos steps in. We act as a single vendor for tax compliance, providing peace of mind and allowing you to reclaim time to focus on growing your business.
No, there are no mandates for issuing electronic invoices in the Czech Republic. However, public authorities are required to be able to receive and process e-invoices should a supplier voluntarily issue one.
B2C e-receipts were abolished in 2023. The EET portal and related infrastructure have been decommissioned. As a result, there is no longer a legal obligation to issue e-receipts or report sales in real time, and taxpayers cannot voluntarily continue using the EET system.
While Hungary does not explicitly mandate the issuance of electronic invoices for most transactions, the country’s real-time invoice reporting (RTIR) scheme applies to all taxpayers and companies.
This can make understanding your requirements difficult, but this overview makes compliance simple. Be sure to bookmark the page to stay ahead of any future regulatory changes.
There is no mandate to issue and receive e-invoices for business-to-business (B2B) transactions in Hungary.
That said, businesses are required to participate in Hungary’s real-time invoice reporting (RTIR) scheme. This model allows for e-invoicing, though it doesn’t mandate it, given that it requires taxpayers and companies to report their invoice data to the Hungarian tax authorities in real time.
E-invoicing can be voluntary, provided the buyer’s consent is obtained prior to issuance.
B2G e-invoicing in Hungary
Receiving and processing electronic invoices is mandatory for central, regional and local contracting authorities in Hungary.
It is not required for suppliers to issue invoices electronically to these public administrations, however, meaning that e-invoicing is not fully mandated in a business-to-government (B2G) context.
RTIR in Hungary
While there is no e-invoicing obligation in Hungary, the country does require the electronic transmission of invoice data. More specifically, the real-time invoice reporting (RTIR) scheme requires all taxpayers to send their invoice data to the tax authorities as the transactions happen.
Learn the key dates in Hungary’s e-invoicing journey.
1 July 2018: All taxable persons must report invoice data in real-time to the National Custom and Tax administration for domestic transactions with a minimum VAT amount of 100,000 HUF
1 January 2021: All B2C and B2B transactions must be reported to the national tax authorities in real time
1 April 2021: Version 3.0 of Hungary’s real-time invoice data reporting system is implemented
June 2021: All taxpayers must use the NAV Online Invoicing System to submit their invoice data
1 July 2025: E-invoicing becomes mandatory for electricity and natural gas supplies to non-private individuals
1 July, 2030: Hungarian VAT-registered businesses must comply with VAT in the Digital Age (ViDA) requirements, which include mandatory e-invoicing and digital reporting for Intra-Community B2B transactions.
Setting up e-invoicing in Hungary with Sovos
You’re not required to issue electronic invoices in Hungary, but it does benefit some taxpayers to issue and receive them. If that sounds like you, Sovos can help.
If your business operates in multiple countries, you have multiple obligations to meet. Sovos can help there too.
We are the compliance partner of many major companies, a single vendor for all things tax compliance – including e-invoicing.
No, e-invoicing is not mandatory for either B2B or B2G transactions in Hungary. That said, governmental entities must be able to receive and process electronic invoices.
Hungary’s real-time invoice reporting obligation requires all taxpayers to send their transaction data to the tax authorities in real time, however.
