Hi all,
Work to implement our e-invoicing solution with direct integration with the Peppol network (BIS Billing 3.0) is in progress.

We are currently in the final stages of polishing the integration and conducting rigorous testing. Given the critical importance of financial compliance, we are prioritizing stability to ensure the solution is robust upon release in Q1 2026.

Well, we are one week away from the deadline and no support for Peppol yet.
Will they also be late to apply the price increase ?
Vincent S commented 2 months ago
Do you have any updates on this?

Good and also bad news: WHMCS has confirmed that "Peppol BIS 3.0 / EN-16931 E-Invoices: Issue invoices and credit notes that comply with European e-invoicing mandates, ensuring acceptance across borders and in public sector transactions." will be added before the end of this year, along with a price increase effective January 1, 2026 :/

Hi,

Belgian company here. We're actively building an integration for WHMCS to be Peppol compliant via the Billit API before 2026.

Would anyone be interested if we commercialize this module for WHMCS so you can be compliant as well?

We (and several others) have a module running for over 6 months using the Billit API.

Hi all,
We are investigating the possibility of integrating a Peppol solution in WHMCS as an extension of our e-invoicing work: https://requests.whmcs.com/idea/add-electronic-invoicing

Implementing a Peppol solution is rather more involved than a standard e-invoice; requiring submitting invoice data to an accredited Peppol Access Point - whose service fees can be significant - and so choosing an appropriate Access Point with whom to partner is an additional consideration for us.

We will have more specifics and timelines to share in the next few months.

Is it possible WHMCS doesn't react about PEPPOL ?
Robin Cauwenbergh commented 26th June 25
I have finaly a solution i use accountingsoftware and export my WHMCS to Silvasoft, this handle the peppol!: https://netdistri.eu/whmcs-silvasoft
PC commented 28th June 25
Thanks for the link. I will look into this solution. I still hope that WHMCS will wake up.
PF Lareppe commented 25th June 25
As other previously stated : very important for all EU Business and soon mandatory in Belgium.
It should be top priority, if not ready soon, all EU business will have to find alternatives.
Marlon de Graaf commented 18th June 25
Belgium is up first next year (only 6 months to go) and it's mandatory for sending invoices. I felt I should vote for this issue for the whmcs community friends in Belgium.

Maybe we can help by exploring some solutions. I came across billit.eu - according to their website, they offer a free API for sending invoices via Peppol. Do you guys have any other suggestions?
PC commented 21st June 25
@Marlon - I think a lot of people in Belgium (and other european countries) are looking for a solution but WHMCS is not really responding while the time is tikking.
I don't think there is a real solution so far and WHMCS should have this ready a long time ago.

Billit, ING invoice manager, Doccle Pro, Lucy, Comanage, Moneybird, Dexter, .... allemaal alternatieven die geen echt alternatief zijn.
eyewebs.be commented 21st June 25
Our module has been running smoothly for several weeks on our own WHMCS installation and several others, integrated with Billit. It’s a great alternative solution while WHMCS hasn’t provided an official option yet. We’re happy to be legally compliant in the meantime. Feel free to reach out if you’re interested!
eyewebs.be commented 2nd April 25
We've identified a potential solution using a third-party API and want to develop a WHMCS module to automatically send invoices to the Peppol network, primarily for Belgium-based businesses and potentially other European countries.
Olivier LETON commented 8th July 25
Which one ?
Hannes Deburchgraeve commented 2nd April 25
Everyone,
Please vote also on this link: https://requests.whmcs.com/idea/add-electronic-invoicing
Jurgen Michiels commented 2nd April 25
Also, here we need it (also from Belgium), since 99% of our customers are B2B we have no option to get this implement before the end of 2025.
If not we no longer can legally use WHMCS.
Yves Goris commented 1st April 25
My accountant allready introduced another software that I'll use if WHMCS is not updated to PEPPOL. I preffer WHMCS but leave when the option PEPPOL will not be possible.
PC commented 5th April 25
Wich software?
PC commented 24th March 25
It is not only Belgium, Currently, 31 countries in Europe have OpenPeppol members (Peppol access points or Peppol service providers). 19 of these countries use the Peppol network as part of their B2G e-invoicing legislations. These countries include Austria, Belgium, Croatia, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Lithuania, Luxembourg, The Netherlands, Norway, Poland, Sweden and the United Kingdom
