    What is UBL?

    UBL (Universal Business Language) is a standardized XML file format designed to simplify the automation of financial information exchange. It includes all the details of a manual invoice, including customer data, amounts, and product information, in a standardized and structured format. This allows seamless communication between different software systems globally while ensuring compliance with the fiscal requirements of each receiving country.

    Originally introduced in 2004 for small to medium-sized businesses (SMEs), UBL has evolved into a vital tool for international procurement and e-invoicing. By simplifying the invoicing process, UBL minimizes manual data entry and resolves compatibility issues between various accounting systems, thereby improving the efficiency of cross-border transactions and invoicing.

     

    Why is UBL Important?

    Sending and receiving invoices abroad used to be complex, expensive, and confusing because of multiple standard formats. Therefore, UBL is more than just a technical format. It was developed by the OASIS (Organisation for the Advancement of Structured Information Standards), designed to be used globally, for businesses of all sizes. But why do people care about it so much?

  • Global Standardization: UBL eliminates the need for custom formats, enabling consistent communication between businesses worldwide.
  • Scalability: UBL supports a wide variety of business transactions, allowing businesses to scale their solutions to accommodate larger client bases and diverse use cases.
  • Regulatory Necessity: With increasing mandates for e-invoicing, adopting UBL ensures compliance with regulations and provides a competitive edge to companies not mandated or implementing it voluntarily.
  • Improved Business Efficiency: By enabling faster processing, error reduction, and better data accuracy, UBL improves overall operational efficiency.
  • Digital Transformation: Reduces reliance on paper-based processes.

    UBL and the Peppol Network

    UBL is closely linked to Peppol, a global e-procurement network that enables businesses and governments to exchange electronic documents efficiently. This connection is crucial: through Peppol, companies can send e-invoices and other key documents. UBL serves as the standardized format that ensures these documents comply with the varying fiscal and legal requirements of different countries.

     

     

    How Does UBL Work?

    UBL is a markup language and serves as a framework to structure and describe information and data so that software can understand and interpret it. Because it is an XML document, the text elements and labels are written in code. Hearing that it is built out of code might seem complicated, but the UBL is particularly popular because of its simplicity, distilled into just two straightforward steps:

  • Creating a UBL Document: Most modern accounting programs offer the ability to export invoices in UBL format. In it, you record essential business information related to a transaction.
  • Sending and Processing: Once the document is created, it can be transmitted to other systems over a private network using secure protocols. In addition, given the advances in current software and systems, the recipient can automatically process the document, store it, and manage it conveniently.
  •  

    How to Read an UBL Invoice

    Instead of manually entering data from an invoice, the UBL files can be processed automatically by your invoicing software. The processing steps would therefore look something like:

  • You receive a UBL document via email or an online portal (like Peppol).
  • Your accounting or ERP system automatically imports the UBL file.
  • The software extracts information such as invoice numbers, customer details, amounts, and VAT rates from the file and processes them.
  • The software performs checks to detect errors, such as whether the VAT is correct or the total amount matches the specifications.

    What Are the Countries That Require the UBL format?

    Governments globally recognize the benefits of the UBL format and electronic invoicing, both for themselves and businesses. It allows them to keep track of the transactions almost in real time and eliminate manual mistakes, therefore reducing tax fraud. Because of that, governments all around the world are implementing regulations and laws to encourage or mandate the UBL and e-invoicing adoption. Here is a list of countries requiring the UBL format:

     

    Europe

  • Denmark: A pioneer in UBL adoption, Denmark mandated OIOXML (UBL 0.7) for government procurement in 2005. Later, it upgraded to OIOUBL (UBL 2.0), achieving cost savings of €500 million.
  • Spain: Employs UBL for electronic invoice encoding, with support from the UBL Spanish Localization Committee.
  • Belgium: Uses a UBL customization, E-FFF, to enhance e-invoice interoperability.
  • Sweden: Implements Svefaktura (a UBL customization) and mandates Peppol for government entities.
  • Italy: Plans to adopt UBL 2.1 syntax for e-procurement, aligning with European standards.
  • The Czech Republic: Utilizes ISDOC, based on UBL 2.0, for e-invoicing.
  • Norway: Uses EHF, based on UBL and CEN BII standards, for e-invoicing.
  • Portugal & Sweden: Both operate with UBL as the standard for public administration transactions, aligning with EU regulations since 2019.
  •  

    Asia-Pacific

  • Japan: Uses UBL for B2B document exchange.
  • Australia & New Zealand: Adopted a UBL 2.1 subset for invoicing, fostering digital participation and economic growth.
  •  

    The Americas

  • Colombia: Implements UBL 2 for electronic invoicing, supported by DIAN, the national tax authority.
  • Peru: Migrating from UBL 2.0 to UBL 2.1 under SUNAT’s guidelines.
  • United States & Canada: The Business Payments Coalition developed a UBL 2.2 semantic model for e-invoicing.
  • Latin America: Countries like Mexico, Chile, Colombia, and Brazil promote UBL for digital invoicing.
  •  

    Middle East

  • Turkey: Adopts UBL-TR, a customized version for its e-invoicing system.

    Benefits of using Universal Business Lenguage

    UBL provides multiple different benefits for both the receiver and sender. That by itself is already a benefit, as it makes it a point of interest for everyone. Imagine sending the UBL to optimize your process and the receiver doesn’t have the software to open it. Another important advantage for both sender and recipient is the automation and extra security when sending and processing e-invoices.

     

    Benefits for the Reciever

  • You no longer have to perform manual operations to process invoices. Invoice data is automatically transferred from XML, saving you a lot of time and money.
  • Because you do not have to retype invoices, the risk of expensive human errors is minimized.
  •  

    Benefits for the Sender

    If you are the one thinking about issuing UBL documents, the list of benefits is really long:

  • Customer satisfaction increases, because they can process your invoices more easily.
  • Businesses can automate the creation, transmission, and processing of various commercial documents that affect your accounting.
  • UBL format allows businesses to integrate it easily with various systems, ensuring compatibility across multiple clients and partners.
  • UBL is widely accepted in e-invoicing regulations, including Peppol standards in Europe, ensuring compliance with both local and international mandates. It enables cross-border e-invoicing, making it ideal for global trade. To go even one step further, UBL supports seamless integration across many different platforms.
  • The format eliminates manual data entry, ensuring 100% accurate, automated processing with no human intervention.
  • UBL invoicing reduces the costs associated with document management and information exchange. For example, your investment in storage space, materials, and human resources will be much lower than in the past.
  • The cash flow is also improved, allowing for faster payments. On average, they are paid 16 days faster than manual invoices.
  • Another reason why UBL has also been chosen is its sustainable nature. Since everything is digital and in electronic format, the consumption of materials such as paper is significantly reduced. Thus, the environmental impact that companies have on the planet and its natural resources is much lower.

    What are the challenges in processing a UBL file?

    UBL by itself doesn’t have that many challenges. The biggest problem is more that it is still a fresh thing, at the beginning of its lifetime, and the complete global adoption hasn’t happened yet. Therefore, the most common challenges are:

  • Adoption Limitations
  • Version Inconsistencies
  • Non-Digital Invoices
  • Invoice Image Retrieval
  • Efficient Workflow
  •  

    How do you tackle the UBL challenges?

    Set up your system in such a way that it allows you to process not only UBL invoices but also non-UBL invoices digitally. In other words, make sure you can scan invoices received via mail and submit PDF purchase invoices to your OCR solution.

    In addition, provide a simple solution that helps you itemize lines, match them with a purchase order, or transact for proper monitoring. Also, invest in a workflow solution that allows you to efficiently and easily submit digitally received non-UBL and UBL invoices to the appropriate approver so they can approve the invoice and proposal entry.

     

     

    How to Integrate the UBL Format

    One of the key benefits of UBL is its integration capabilities, as many systems can integrate the tools that generate UBL files, providing benefits for all company sizes.

    The process of UBL integration proceeds as follows:

  • Analyze Requirements
  • Technical Setup
  • System Integration
  • Testing and Validation
  • Compliance Check
  • Deployment
  • Maintenance and Updates
