Invoice Fiscalization Requirements in Europe: An Overview

In this article, we will provide an overview of fiscalization in Europe, focusing on the specific requirements and obligations imposed on companies.

Invoice fiscalization is a critical component of modern business operations, particularly for companies operating in Europe. It involves the integration of technology and legal frameworks to ensure compliance with tax regulations, combat tax evasion, and enhance transparency in financial transactions. In this article, we will provide an overview of fiscalization in Europe, focusing on the specific requirements and obligations imposed on companies, with an emphasis on the B2B Software-as-a-Service (SaaS) industry and the opportunities to automate the fiscalization process by using APIs for invoicing fiscalization compliance.


Fiscalization Objectives

Fiscalization is a strategic approach that governments employ to achieve multiple objectives, benefiting both tax authorities and businesses. By implementing robust fiscalization systems, governments aim to:


Enhance Tax Compliance:

  • Fiscalization systems ensure businesses accurately report their financial transactions, reducing opportunities for tax evasion and improving overall tax compliance. This helps governments collect taxes more effectively, ensuring the financial health of the nation.

    Combat Tax Fraud:

  • With the integration of advanced technologies, fiscalization systems provide better control and monitoring of financial transactions, minimizing the risk of fraudulent activities such as falsifying invoices, underreporting revenues, or manipulating tax records. This enables tax authorities to identify and investigate potential fraud cases more efficiently.

    Improve Transparency:

  • Fiscalization promotes transparency in business operations by requiring companies to maintain accurate and auditable records of financial transactions. This transparency helps to build trust among stakeholders, fostering a fair and competitive business environment.

    Accurate Financial Reporting:

  • Fiscalization ensures that companies maintain accurate financial records, including invoices, receipts, and transaction data. By standardizing reporting processes, governments can gather reliable financial information for tax assessment and auditing purposes.

    Streamlined Tax Collection:

  • By implementing fiscalization, governments can streamline the tax collection process, enabling businesses to meet their tax obligations efficiently. This minimizes administrative burdens and facilitates the timely and accurate submission of tax payments.

    Simplified Compliance Procedures:

  • Fiscalization aims to simplify compliance procedures for businesses by providing clear guidelines and requirements for financial reporting. This reduces the complexity of tax compliance, allowing companies to focus on their core operations.

    Country-Specific Requirements

    While there are overarching principles and guidelines established by the European Union (EU), individual countries within Europe have their own specific fiscalization requirements. It is crucial for companies operating across borders to be aware of these variations to ensure compliance in each jurisdiction.

    Here, we highlight a few examples. For a more comprehensive overview of fiscalization requirements on a country-by-contry basis, refer to this helpful guide provided by Space Invoices, a company that provides an API that automates the fiscalization process for software organizations. The list can be found here.



    In Germany, invoice fiscalization is primarily governed by the GoBD (Principles for Proper Management and Storage of Books, Records, and Documents in Electronic Form). B2B SaaS companies must adhere to these principles, which include requirements for secure storage, integrity, and auditability of electronic documents.



    France enforces invoice fiscalization through the SER (Recording System for Receipts). B2B SaaS companies are obligated to maintain reliable and certified systems that record sales, invoice details, customer information, and transaction amounts, which must be made available for review by tax authorities.



    For invoice fiscalization, Spain employs the SII (Immediate Supply of Information) system, requiring B2B SaaS companies to submit detailed transactional data to the tax administration in near real-time. This includes invoices, customer data, and associated tax rates.



    In Slovenia, fiscalization requirements mandate that businesses, including B2B SaaS companies, issue electronic invoices in a structured format through the "eDavki" system. These invoices must be electronically transmitted to the tax authorities for validation and storage. For more information on fiscalization requirements in Slovenia, see this post.



    In Croatia, invoice fiscalization requirements oblige businesses, including B2B SaaS companies, to use the "Jedinstveni Informacijski Sustav Porezne Uprave" (JIRP) or "Single Information System of the Tax Administration" for electronic invoicing. B2B SaaS companies must ensure that their invoices are issued in a structured format and sent to the tax authorities for validation and archiving. For more information on fiscalization requirements in Croatia, see this post.



    In Italy, invoice fiscalization requirements revolve around the "Sistema di Interscambio" (SDI), an electronic invoicing system. B2B SaaS companies are obligated to issue electronic invoices through the SDI, ensuring compliance with specific technical standards and submitting invoices to the tax authorities for verification. For more information on fiscalization requirements in Italy, see this post.



    In Portugal, invoice fiscalization requirements center around the "Fatura Eletrónica" system, which mandates B2B SaaS companies to issue electronic invoices in a standardized format. These invoices must be sent to the tax authorities for validation and archiving. For more information on fiscalization requirements in Portugal, see this post.

    Solutions for Automating Invoice Fiscalization Compliance

    To navigate the complexities of fiscalization, B2B SaaS companies can leverage API-based software solutions. These solutions offer automated features that streamline compliance processes, including:


    Invoicing Compliance:

  • API-based solutions generate invoices that meet the specific requirements of each country, ensuring businesses issue compliant invoices consistently.

    Real-time Data Exchange:

  • API-based software solutions facilitate the automated exchange of transactional data with tax authorities in near real-time, ensuring timely reporting and compliance with fiscalization obligations.

    Validation and Verification:

  • APIs provide built-in validation checks to ensure the accuracy and integrity of invoice data, minimizing errors and potential compliance issues.

    Data Storage and Retrieval:

  • API-based solutions offer secure cloud storage options for fiscalization-related data, ensuring compliant storage and easy retrieval for audits or tax inspections.

    Stripe is a market leading payments company that includes some invoicing features. However, Stripe does not support fiscalization. A company that supports automated fiscalization with a unified API is called Space Invoices. Their solution can serve as just a fiscalization engine, or can also provide low-cost payment processing that is integrated with their fiscalized invoices.

    The landscape of fiscalization and e-invoicing is continuously evolving. Some key trends to watch for in the future include:



  • Efforts are underway to harmonize fiscalization requirements across European countries, streamlining compliance processes and facilitating cross-border operations for businesses.

    Blockchain Technology:

  • Blockchain-based solutions are being explored to enhance the security, integrity, and transparency of fiscal transactions, providing immutable records and traceability.

    Digitalization of VAT Compliance:

  • Automation and digitalization technologies are simplifying VAT compliance processes, reducing administrative burdens for businesses.
