This is the big kahuna that we’ve been working on for months. We’ve built a replacement for the current invoice module on SystemOne, aka InvoiceV1 or Classic workflow.
A noticeable difference is that there are 4 clear life cycles: draft, review, outstanding, and settled. This new, structured approach in InvoiceV2 is more resilient from an accounting perspective and opens the door to exciting new features like digital invoicing (Peppol) and automatic reminders.
The new V2 version looks familiar if you’ve used InvoiceV1 and eSign, so we expect you can find your way around it easily. But if you need a bit of help, feel free to reach out to us at support@systemonesoftware.com.
Let’s go through some of the big updates you’ll enjoy from now on using InvoiceV2:
100% Peppol compliant
Digital invoicing or eInvoicing is a big theme in many countries. From 1 January 2026, businesses in Belgium need to send their invoices digitally over a shared network called Peppol. If you see your country on this list, you’re likely already required to do this or will soon be.
We’ve gone to great lengths to build a workflow that seamlessly integrates SystemOne with Peppol, so our customers don’t need an external solution to submit their invoices and credit notes.
The big win for you is that you can keep working and doing everything in One System, without having to adopt another software ;)
We’ve onboarded most of our clients in Belgium onto the new workflow, so we’re ready for the new year.
The next big focus will be on eRechnung in Germany and helping our German customers become eInvoicing compliant in 2026.
Standardized templates
Invoices are now generated as PDFs. You can customize the template in your bookkeeping with your logo and header & footer.
The driving factor behind this change is standardization and eInvoice compliance.
Previously, the customized Word templates were unstructured, which meant information could get lost in any digital exchange—not eInvoice-friendly!
PO number
Government and larger corporations often need a reference to their purchase order (PO) on their invoice. Without this buyer reference, they can’t accept your invoice.
We’ve introduced a new field in InvoiceV2 to store this information. It will automatically appear on the invoice PDF.
The reference is relevant when you’re submitting to the Peppol network. We made sure it’s included in the right place on the invoice.
Automatic reminders
One of the major improvements in InvoiceV2 is the automatic reminder feature for outstanding invoices, as part of your dunning process.
Users can configure default settings for the reminder intervals and control when emails are sent. SystemOne provides default email templates out of the box, and users can customize this content to match their own tone and preferences.
On a per-invoice basis, users can also change scheduled reminders, for example, when working with a trusted partner.
Activity panel in invoice detail view
With this new panel in the detail view, we track the history of everything that happened to the invoice.
You can see what was changed, when, and by whom.
Automatically email invoice to accounting software
A frequently requested feature was to have every InvoiceV2 mailed to the customer’s accounting software.
This can be activated by configuring the email address of your accounting software on the bookkeeping detail page.
The email includes the Invoice PDF and a UBL XML file that has invoice data in a structured format.
