Effortlessly handle mandatory e-invoicing for your webshop

The e-commerce and business transaction landscape is in constant motion. Technological innovations, evolving customer expectations, and new regulations are propelling the sector forward. One of the most significant shifts on the horizon is Belgium’s mandatory e-invoicing initiative. Starting January 1, 2026, the practice of sending electronic invoices (e-invoices) to B2B clients will be a legal obligation. This represents a profound transformation for many businesses still dependent on traditional invoicing methods like emailed PDFs or paper invoices.

But what does this regulatory change mean for your webshop, specifically? And how can you optimally prepare, without compromising the efficiency and ease of use of your online store? In this blog post, we’ll take a deep dive into Belgium’s e-invoicing mandate, demonstrating how PEPPOL Commerce not only helps you meet the new legislation but can even provide a strategic edge.

Belgian e-invoicing requirements: Key information you need

Starting January 1, 2026, Belgium will legally require you to send electronic invoices (e-invoices) to your business clients (B2B). This initiative, aligned with a wider European push for digitalizing government services and business transactions, seeks to combat fraud, boost efficiency, foster transparency, and promote sustainability.

What does that mean for your invoicing process?

The new legislative proposal specifically targets B2B transactions. This means that when you send invoices to other companies, you are required to use a structured electronic invoice format that complies with Peppol standards. Simply sending a PDF invoice via email or by post to business clients will no longer be legally permitted from January 1, 2026.

Important for your WooCommerce webshop: The new legislation applies to all B2B invoices, regardless of whether you are a purely B2B-focused company, operate a hybrid model (with both B2B and B2C clients), or even have a primarily B2C webshop that incidentally sells to business clients.

The challenge for webshop owners

Many webshop owners who use platforms such as WooCommerce, Easy Digital Downloads, or FluentCart are already feeling the impact of this change. The shift to e-invoicing brings with it specific challenges:

Compatibility with existing systems: Do your current plugins and processes work seamlessly with the required e-invoicing standards? Often, standard invoicing plugins or those that only generate PDFs are insufficient.
Complexity of Peppol: The Peppol network and its associated standards can seem technically complex. Setting up and managing this infrastructure yourself requires specific knowledge
Hybrid models (B2C and B2B): How do you handle customers who require a different invoicing process? After all, your webshop can serve both consumers (B2C) and businesses (B2B). Manually separating these streams is labor-intensive and error-prone.
Time pressure and costs: The January 1, 2026 deadline is fast approaching. Implementing a new solution takes time and requires an investment. Without the right approach, this can lead to stress and missed opportunities.
Customer Experience: How do you guarantee a smooth transition to e-invoicing for all your clients, whether they are businesses or individuals? You want to avoid introducing additional administrative burdens for your loyal customer base.

PEPPOL Commerce: The intelligent solution for all webshop types

Enter PEPPOL Commerce. We recognize that not all webshops are exclusively B2B. Many entrepreneurs cater to a blend of consumers (B2C) and business clients (B2B). Consequently, we’ve engineered our plugin to flexibly manage both customer types, all while considering the new Belgian legislation.

How does it work for your webshop in practice?

You can easily configure how your invoices are processed with PEPPOL Commerce, based on customer type. Consumers will receive their invoices in the familiar way: automatically emailed as a user-friendly PDF. This guarantees a seamless and trusted experience for your private customers

Your B2B clients experience the full strength of PEPPOL Commerce. When an invoice is for a business customer, it’s automatically generated and sent through the Peppol network. This immediately complies with Belgium’s 2026 legal mandate for B2B invoicing. At the same time, your B2B clients will also receive an email containing both the PDF and XML versions of the invoice. This provides them the flexibility to utilize the invoice as needed, for their internal administration and system processing.

An invoice with a great presentation, both digitally and visually

An invoice is more than just a document; it’s also a calling card for your business. That’s why PEPPOL Commerce offers you the ability to fully configure your invoice layouts yourself. Add your logo, adjust the colors, and organize the information in a way that perfectly matches your brand identity. This ensures that your invoices, in both PDF and XML format, exude professionalism and recognition, contributing to a stronger brand identity and customer experience.

No extra effort needed for Peppol integration

Although all Belgian companies are required to be registered on the Peppol network from 2026 onwards – for example, to receive e-invoices from suppliers – as a user of PEPPOL Commerce, you don’t need to worry about the technical side of sending them. As soon as you activate our plugin, we handle the standard integration with the Peppol network for you. You don’t need to take any extra steps; the technology works in the background, allowing you to focus on your business.

Our 5 key principles in developing PeppolCommerce

Our WordPress plugin is built upon these pillars, focused on optimizing your business processes:

Complete automation of the invoicing process: Say goodbye to manually generating, downloading, uploading, and sending invoices. PEPPOL Commerce automates the entire process. You configure once which order status triggers the invoice creation, and the rest happens automatically.
Seamless integration into your current workflow: You don’t need to learn or implement new, complex systems. PEPPOL Commerce works seamlessly within your familiar WooCommerce (or EDD/FluentCart) environment. The plugin integrates with your existing processes, resulting in a minimal learning curve and quick implementation. This saves you valuable time and resources.
Flexibility for hybrid business models: As described above, PEPPOL Commerce automatically recognizes and processes the difference between B2C and B2B customers. You can decide yourself whether to send the invoice via Peppol (with PDF/XML) or only via email (as PDF), depending on the customer segment. This makes our plugin highly suitable for businesses with a mixed customer base.
Radical time savings and error reduction: The time savings are enormous. Think of the hours you currently spend on manual invoicing. PEPPOL Commerce reduces this to a few minutes per month for checking. Moreover, automation eliminates the chance of human errors, such as incorrect uploads or forgotten invoices, leading to a higher degree of professionalism and reliability.
Prepared for the (near) future: By investing in PEPPOL Commerce now, you not only become compliant with the new Belgian legislation from 2026 onwards, but you also position your business as a frontrunner in the digitalization of business transactions. This can even lead to faster payments and improved relationships with your B2B clients.

Is it really that simple?

Our Peppol Commerce plugin is designed for simplicity. The process usually involves just three easy steps:

Installation & Activation: Install PEPPOL Commerce from your dashboard, just like any other WordPress plugin. No complicated coding involved
Configuration: You open the settings and enter your business details (including your VAT number). Here you also directly set the desired layout for your invoices and configure the different invoicing flows for your B2C and B2B customers. The Peppol network connection is pre-set, so you don’t need to worry about it.

Setting up the Workflow: You determine at which order status the invoicing should automatically take place (e.g., upon ‘Completed’ or ‘Shipped’). You can also set your preferences for B2C and B2B customers here.

That’s it. From that moment on, your invoicing will be fully automated, compliant with future Belgian legislation, and your plugin will also handle the perfectly formatted invoices for all your customers.
