However, adopting this system requires compliance with a series of technical and legal requirements.

In this guide, we will explore in detail what eBill is, its advantages, and how to adapt to it. 

We will also address international regulations and specific ones in Spain, such as the Crea y Crece Law (Create and Grow Law) and the VeriFactu Regulation. Our goal is to provide a comprehensive and practical overview so that your company can make the most of this new billing system, which in many cases is already mandatory.

What is eBill?

The eBill is a digital document that replaces the paper invoice. This type of invoice is generated, sent, and received electronically. 

Unlike traditional invoices, digital bills must meet certain technical and legal requirements that ensure their authenticity, integrity, and readability.

The history of digital billing dates back to the late 20th century. With the expansion of the internet and information technologies, the need to modernize accounting processes emerged. Initially, digital invoices were simple PDF files. 

However, these documents lacked legal validity and the necessary security to prevent fraud.

The evolution of eBilling has been driven by international regulations. In Europe, Directive 55/2014 was a significant milestone. This regulation established the mandatory use of eBills in transactions with public administrations. Globally, many countries like Argentina, Brazil, and Mexico have followed this example by implementing their own regulations.

Today, eBilling is a standard in most advanced economies. This system has proven to be more efficient, secure, and environmentally friendly than paper use. Furthermore, it facilitates regulatory compliance, reduces operational costs, and improves the relationship between companies and administrations.

Benefits of eBilling

eBilling offers multiple benefits for companies and organizations. These benefits go beyond simple digitalization, encompassing improvements in efficiency, security, and sustainability.

Efficiency and cost reduction 

eBilling automates the process of issuing and receiving invoices, eliminating the need to print, mail, or store paper documents. This significantly reduces costs associated with materials, time, and storage space. 

Additionally, it streamlines the workflow, allowing for faster and more efficient invoice management. Processing time is reduced, thus improving the payment cycle and liquidity of companies.

Improvement in security and regulatory compliance

eBills must meet technical requirements that ensure their authenticity and integrity. This includes digital signatures and the use of structured formats that prevent tampering. 

Moreover, eBilling facilitates compliance with tax regulations by integrating with management systems and automatically reporting to authorities. This minimizes errors and reduces the risk of penalties.

Impact on sustainability 

The use of eBills significantly reduces the consumption of paper and other resources associated with paper invoicing. 

By digitalizing the process, companies decrease their carbon footprint, contributing to more sustainable and environmentally friendly practices. This, in turn, enhances corporate image and demonstrates a commitment to sustainability.

International Regulations on eBilling

eBilling is regulated by norms that vary depending on the country or region. 

These regulations establish the technical and legal requirements to ensure the validity of electronic invoices and their acceptance by tax authorities.

General requirements for eBilling 

Globally, the general requirements for eBilling include the authenticity of origin, content integrity, and document readability over time. 

These requirements are achieved through the use of digital signatures, structured formats (such as XML or UBL), and the secure storage of documents. In many cases, companies must also report eBills to tax authorities in real time or periodically.

Key differences between countries and regions 

The regulations on eBills vary significantly between countries. In Argentina, eBilling has been mandatory since 2007, making it one of the first countries to adopt it. Following its example, Mexico, Chile, and Brazil implemented similar systems with strict rules on invoice issuance and reporting.

In the United States and Canada, eBilling is widespread, especially among large companies. However, its adoption is not mandatory and remains a voluntary option. 

On the other hand, in China, the e-Fapiao system has fully digitalized invoices, requiring taxpayers to use official platforms for their issuance and registration. In the European Union, Directive 55/2014 has harmonized the requirements for eBilling in public transactions, but there are variations in implementation among countries.

The European Directive 55/2014 and its global impact 

The European Directive 55/2014, also known as the eBilling Directive, has been a milestone in the standardization of eBilling within the European Union. This regulation mandates public entities in member states to accept eBills in a structured format, ensuring interoperability between different systems. 

Its implementation has served as a model for other regions and has accelerated the global adoption of eBilling. The Directive has helped reduce bureaucracy and administrative costs, improving efficiency in both public and private transactions.

This European regulatory framework has influenced other advanced economies, promoting .the adoption of eBilling as a global business standard

Implementation of eBilling in Companies

Adopting eBilling is a process that requires planning and the integration of new technologies into business management. 

Below are the key steps to effectively implement this system and how to integrate it with existing ERP and accounting systems.

It is essential that the eBilling software is compatible with the ERP and that the integration is smooth to maintain data and process consistency.

Particularities of eBilling in Spain

In Spain, eBilling has been driven by various regulations aimed at modernizing administrative and fiscal processes, improving transparency, and combating fraud. 

Two of the most important regulations in this area are the Crea y Crece Law and the VeriFactu Regulation, each with its own objectives and requirements.

The Crea y Crece Law and its impact 

The Crea y Crece Law, formally known as Law 18/2022, of September 28, aims to promote business growth and reduce late payments in commercial transactions in Spain. 

This regulation focuses on the mandatory use of eBilling in commercial relationships between companies and freelancers, regardless of their size or turnover. The law establishes that all companies, including SMEs, must adopt eBilling to improve transparency and traceability in commercial payments.

One of the most notable aspects of the Crea y Crece Law is the obligation of interoperability between billing platforms. This means that the different software solutions used by companies must be able to communicate with each other without additional costs for the parties involved. 

This requirement aims to prevent technological monopolies and facilitate access to eBilling for all companies, especially smaller ones.

Additionally, the law includes staggered deadlines for its implementation, ranging from 12 months to two years, depending on the company's turnover. These deadlines allow for a gradual transition, especially for small and medium-sized enterprises that may need more time to update their systems and processes.

The implementation of this law represents a significant change in the Spanish business ecosystem, as it promotes digitalization and transparency in commercial relationships while simultaneously reinforcing the fight against late payments. 

The Crea y Crece Law not only seeks to improve the operational efficiency of companies but also ensures that payments are made on time, thereby strengthening the financial stability of businesses.

VeriFactu: Compliance and Technical Requirements

VeriFactu is an essential component of the Spanish government's strategy to combat tax fraud. Implemented under the framework of the Anti-Fraud Law (Law 11/2021), VeriFactu sets a series of technical requirements that eBilling systems must meet to ensure the authenticity and traceability of invoices issued in Spain. 

This regulation focuses on preventing invoice manipulation and ensuring that accounting records are accurate and transparent.

One of the key aspects of VeriFactu is the prohibition of "dual-use software", which refers to programs that allow parallel accounting or manipulation of invoices to hide income. 

Billing systems must guarantee the integrity, accessibility, readability, and preservation of data throughout the period required by tax regulations. 

In addition, they must be able to automatically register and report invoices to the Tax Agency, thus facilitating supervision by the tax authorities.

VeriFactu will come into force on July 1, 2025, but its implementation is phased. From the publication of the Ministerial Order that will develop the specific technical aspects, software developers and vendors will have 9 months to adapt their solutions to the new requirements. 

Other companies, including SMEs and freelancers, will have until the effective date to comply with the regulations.

Compliance with VeriFactu is mandatory for all Corporate Tax and Personal Income Tax payers, with some exceptions, such as those covered by the Immediate Supply of Information (SII) system or using TicketBAI in the Basque Country. 

The regulation also states that it is not mandatory to have software that automatically sends invoices to the Tax Agency, but it is necessary that the system used meets all the technical requirements of the regulations.

VeriFactu represents an important step in the modernization of the Spanish tax system, ensuring that all companies use billing tools that offer maximum transparency and security. This approach not only strengthens the fight against fraud but also simplifies administrative and accounting processes for companies, reducing the bureaucratic burden and improving operational efficiency.

Challenges and Best Practices for International eBilling

The adoption of eBilling at an international level presents several challenges, both legal and technological. However, with the right strategies, companies can overcome these barriers and leverage the benefits of this system globally.

Overcoming legal and technological barriers 

One of the main challenges of international eBilling is the diversity of regulations. Each country has its own legal requirements for issuing, storing, and reporting eBills. This can complicate operations for companies that work across multiple jurisdictions. 

To overcome these barriers, it is crucial to stay informed about the regulations in each market in which the company operates. Collaborating with local legal and tax experts can be an effective strategy to ensure regulatory compliance in each country.

In the technological field, compatibility between systems is another challenge. Different countries may require specific formats for eBills, which complicates the integration of billing systems. 

To address this issue, it is advisable to choose software solutions that support multiple formats and can adapt to the regulations of different countries. Additionally, constantly updating the software to align with regulatory changes is essential to avoid compliance issues.

Ensuring interoperability and compatibility 

Interoperability is key for international eBilling. Ensuring that billing systems from different countries and companies can communicate with each other is fundamental for guaranteeing an efficient workflow. 

One of the best practices to ensure interoperability is adopting international standards, such as UBL (Universal Business Language) or XML, which are widely accepted and allow compatibility between different systems.

It is equally important to choose a billing software provider with experience in international markets and that offers support for integration with multiple platforms. This approach not only facilitates the issuance and receipt of invoices between different countries but also helps to minimize errors and maintain consistency in financial data.

Finally, participation in global interoperability initiatives, such as PEPPOL (Pan-European Public Procurement On-Line) in Europe, can be an effective strategy for companies seeking to operate seamlessly across multiple markets. These networks provide a common framework that facilitates the communication and exchange of eBills between different jurisdictions and sectors.

The Future of eBilling

eBilling is constantly evolving, driven by technological advancements and regulatory changes that seek to improve efficiency and transparency in commercial transactions. 

The future of eBilling is shaping up as a dynamic field, where automation, artificial intelligence (AI), and globalization will play crucial roles.

Emerging trends 

One of the main trends is the advanced automation of processes. eBilling solutions are increasingly incorporating automation tools that allow the issuance, receipt, and validation of invoices without human intervention. 

This automation not only reduces errors but also speeds up billing cycles and improves operational efficiency. Integration with technologies such as AI and machine learning will enable predicting and solving problems before they occur, further optimizing processes.

Another trend is the growing adoption of eBilling in emerging markets. As more countries implement regulations that mandate or encourage the use of eBilling, we will see an increase in its global adoption. 

This will facilitate international transactions and reduce trade barriers, especially in regions where bureaucracy and lack of transparency have historically been problematic.

The role of AI and automation 

Artificial intelligence and automation are transforming eBilling. In the future, billing systems are expected to be capable of analyzing large volumes of data in real-time, identifying behavior patterns, and anticipating potential non-compliance or fraud. 

For example, AI can automate the verification of compliance with local regulations, quickly adapting to regulatory changes.

Additionally, automation will allow for greater customization in invoice management, dynamically adjusting workflows according to the specific needs of each company. This includes everything from the automatic management of early payment discounts to immediate accounting reconciliation, improving liquidity and reducing late payments.

As global trade expands, the need for interoperability between billing systems from different countries becomes more critical. The future of eBilling will be marked by the consolidation of international standards that facilitate the exchange of documents between companies in different jurisdictions. Initiatives such as the PEPPOL network and the harmonization of regulations at the regional level, such as in the European Union, are important steps in this direction.

Globalization will also bring greater collaboration between governments and companies to create more flexible regulatory frameworks that promote innovation without compromising security and compliance. In the long term, we are likely to see a convergence towards a globally accepted eBilling system, where technological and legal barriers are minimized.

In summary, the future of eBilling will be defined by the integration of advanced technologies, the global expansion of its use, and the creation of an interoperable and secure environment that promotes efficiency, transparency, and regulatory compliance on a global scale.
