E-invoicing: Global compliance for international finance teams

Make e-facturation the powerful starting point of your Order-to-Cash process.

Ensure global compliance for every mandate, automate both sending and receiving via Peppol, and gain real-time control over your cash flow with one seamless connection for 30+ countries. Be fully prepared for upcoming legislation within 8 to 10 weeks and reduce your DSO with the only solution that integrates natively with your credit management.

Remove the complexity from international invoicing.

The world of invoicing is changing at a rapid pace. Waiting for a mandate to take effect (such as in Belgium) carries significant risks: from unpaid international invoices to stagnating sales due to non-compliance. Manual processes and PDF invoices result in a 'delivery black hole', where you have zero insight into the status of your invoice. Onguard E-invoicing connects your ERP directly to the Peppol network and local authorities in 30+ countries, allowing you to resolve issues before damage occurs.

From delivery to collection: close the Order-to-Cash cycle

What makes Onguard unique is our vision that seamlessly connects everything from invoice to payment. Where other e-invoicing providers stop at delivery, we go further. Statuses from the Peppol network (Invoice Response) flow directly back into your Onguard Credit Management solution.

  • Confidence upon acceptance: Once an invoice is accepted, you know immediately that payment is on its way, allowing you to forecast your working capital more accurately.
  • Immediate action upon rejection:If a technical rejection occurs, an action is immediately created for your team within the Onguard Credit Management solution. You resolve the issue before the due date passes.

This creates a closed 'Order-to-Cash' cycle without information loss. You save time, avoid frustration, and reduce your DSO by an average of 7 to 10 days.

Your choice is the same as theirs

The choice between building or integrating.

Are you compliant with the new mandates?

The time for waiting is over. With the B2B mandate in Belgium now officially in effect and countries like Germany, France, and Poland setting their course for 2027 and 2028, e-invoicing is no longer an option but a requirement for international finance teams. Waiting until the deadline is a risk: it leads to unpaid invoices and stagnating sales due to non-compliance.

A single point of contact, your ERP at the core.
Opt instead for one strategic partner and an IT architecture where your ERP remains the central hub. With Onguard E-invoicing, we seamlessly connect your existing technology to the Peppol network and your credit management. This immediately ensures peace of mind, compliance, and maximum control over your O2C chain.

Frequently asked questions about E-invoicing

What is the difference between a PDF invoice via email and e-invoicing?

A PDF invoice is simply a digital image of a paper invoice that still requires manual processing. E-invoicing (via the Peppol network) involves sending structured data (XML) directly from one ERP system to another. This eliminates the 'delivery black hole': you know immediately if an invoice has been received, accepted, or rejected, without any human intervention.

What is the Peppol network and why is it essential?

Peppol is a secure, international network specifically designed for electronic procurement and invoicing. It functions much like a 'telephone network' for invoices. Onguard provides you with a certified Access Point, giving you direct access to thousands of governments and businesses worldwide through a single connection, fully compliant with current security standards.

How does Onguard support international compliance and mandates?

Invoicing legislation changes by country and by year (such as the current mandate in Belgium and the upcoming ViDA guidelines in the EU). Onguard proactively monitors these changes in over 30 countries. Our software acts as a universal translation layer that automatically converts your invoice data into the required local format (such as UBL, XRechnung, or Factur-X), ensuring you always remain compliant without having to modify your own systems.

Can I use Onguard E-invoicing for both sending and receiving invoices?

Yes, this is an integral solution for your entire administration. You can not only send digital invoices to your customers but also automatically receive and process incoming invoices from suppliers. This ensures a fully digitized accounts payable (AP) and accounts receivable (AR) process.

Does Onguard E-invoicing work with my current ERP system?

Our solution is designed to be 'ERP-agnostic.' This means it integrates seamlessly with virtually any system, whether you use SAP, Microsoft Dynamics, Oracle, NetSuite, or a specific legacy package. Through a modern API connection, we link your current landscape to the Peppol network without requiring a complex overhaul of your IT infrastructure.
6. How does the connection lead to a lower DSO (Days Sales Outstanding)?
Because you receive real-time status updates (Invoice Response), you can see immediately if an invoice has been technically rejected by the recipient. Instead of discovering 30 days later that an invoice never arrived, you can take action within minutes. Due to this acceleration in the chain, our customers see an average DSO reduction of 7 to 10 days.

How long does it take to go 'live' with e-invoicing?

While building an in-house connection often takes 12 to 24 months, the implementation of Onguard E-invoicing is typically completed within 8 to 10 weeks. This means you can become compliant in the short term and start benefiting from process improvements well before new international deadlines pass.

What is the benefit of integration with my Onguard Credit Management solution?

This is where our integral O2C vision comes to life. With us, e-invoicing is not a standalone technical process, but the starting point of your collection process. Status information from the Peppol network flows directly back into your credit management workflows. For example, a technical rejection immediately triggers an action for your team, allowing disputes to be resolved before the due date is reached.

Be prepared!
