Nymus Connect is e-invoicing software that connects your ERP system to any invoicing network. With just one integration, you can issue invoices in compliance with Belgian and international regulations.
Nymus Connect is an e-invoicing solution and a certified Peppol Access Point. You can send and receive structured invoices directly from your ERP, in the correct format for each country and each network.
We integrate Connect with your ERP. We have a ready-made connector for many systems, and for others, we build a custom integration. Do you use multiple ERPs at the same time? We’ll integrate them all.
Your ERP data is converted into a single standardized Nymus format. This ensures that every invoice is based on the same structured template, regardless of which system it comes from.
Based on that, we automatically generate the correct Peppol or e-invoicing format for each country, for both outgoing and incoming invoices. If a country requires additional information, we add it as needed.
Once an invoice has been sent, you can track its status in real time: sent, delivered, rejected, or paid. Everything is clearly organized in the Nymus Portal.
You send and receive large, recurring invoice flows. Connect processes them automatically, without letting the volume slow down your process.
You issue invoices from multiple entities, countries, or business units. Connect brings it all together in a single integration and a single overview.

Nymus Connect is e-invoicing software and a certified Peppol Access Point that allows you to send and receive structured invoices. You connect your ERP to Nymus once, submit your invoices in a single structured format, and Connect automatically converts them to the correct format for each country or network. This way, you can invoice in compliance with Belgian regulations and stay prepared for whatever comes your way internationally, without needing a separate solution for each country.
Yes. As of January 1, 2026, all Belgian VAT-registered businesses must send and receive their B2B invoices in a structured format via the Peppol network. A PDF sent by email is no longer sufficient. Nymus Connect ensures your compliance and prepares you for the e-reporting phase that will follow after 2026.
Yes, in most cases it does, even if you’re working with multiple systems at the same time. Connect integrates with common ERPs such as SAP, Business Central, Dynamics F&O, Oracle, AS400, and Navision, as well as older legacy environments. So you don’t need to replace your system. It’s precisely in complex scenarios—involving multiple ERPs or entities—that Nymus really shines: where other providers fall short, we bring everything together into a single structured foundation and a single access point.
Yes, and it’s easier than you think. Your registration on the Peppol network will be seamlessly transferred to Nymus, without any interruption to your invoicing. We’ll guide you through the migration step by step, so you won’t have to deal with duplicate setups or downtime. If you’re stuck with a solution that no longer meets your needs, switching is less disruptive than staying where you are.
Even then, you can continue to issue invoices. Nymus Connect operates on a multi-channel basis: you can reach partners who are already on Peppol in a structured way, and those who aren’t yet can be reached through a different channel. That way, you don’t have to wait for everyone to join, and you won’t lose any invoices along the way. You can read more about this under “multi-channel invoicing.”
Yes. With Connect, you can issue invoices internationally, in any country where your customers or entities are located. Nymus automatically converts your invoice to the correct format for each country, including the corresponding country-specific fields. For countries outside our core market, we work with our partner Arratech to ensure you remain compliant there as well. Learn more about international e-invoicing.
Yes. Nymus is ISO/IEC 27001:2022 certified—the international standard for information security—and audited by DNV. Your invoice data is processed and stored in accordance with the GDPR and remains within a secure environment. For a finance or IT team responsible for sensitive invoicing workflows, this isn’t just a detail—it’s a basic requirement.
That depends on the complexity of your environment, but we deliberately work in clear phases. With a standard ERP integration, you’ll go live faster than with a multi-ERP landscape involving multiple entities. You’ll be assigned a dedicated point of contact who will guide you through the onboarding process—from the integration to the first invoice sent—so you’re never on your own during setup.
The price of Nymus Connect depends on your invoice volume, the number of entities, and the complexity of your ERP environment. That’s why we offer customized pricing instead of a standard rate. What you get is a solution that can handle even complex and multi-ERP scenarios, with personalized Belgian support. Schedule a quick call and we’ll work out the specifics for you.
