Hello,

I am interested in implementing electronic invoicing.
It will be required in many EU countries in following years, and in Croatia it is already partly required, but next year there is plan to be fully required.

Interesting link about that

Merged Ideas
    UBL invoices
    It would be great to have UBL invoices attached to an invoice generated by WHMCS.UBL invoicing becomes more and more popular nowadays.http://ubl.xml.org/wiki/about-ubl
    E-invoices
    HiI already asked many times if it is possible to have this option as well. I was comparing WHMCS to the competitors and see that the other already has a solution for Estonian E-invoices which will be mandatory since Jan 2025.https://hostbillapp.com/features/apps/estonian_e_invoice/https://hostbill.atlassian.net/wiki/spaces/DOCS/pages/2870673409/Estonian+E-invoiceAs other Estonian providers i will need to look for a solution and best would be to have it from my current partner WHMCS, of course.thanks
    Electronic invoicing Spain Verifactu
    Electronic invoicing will be mandatory in Spain and the Verifactu system will be required to prevent dual-use softwareIt would be good to have some integration module withhttps://www.fiskaly.com/signes/verifactuor some other similar module that solves the problem

Howdy Folks!

Just wanted to drop an update and let everyone know that we are aware of this and actively investigating it. We're working hard to understand the core standard requirements as well as the per country requirements and as soon as we have a decision made on the direction we're heading we will radiate that.

We are about to release a Whmcs module to manage electronic invoicing in Italy based on the api of fattureincloud.it the module can be easily integrated with other Italian and foreign intermediaries to manage electronic invoicing also in other countries.

@Gianluca Iannotta Would it work for Belgium?
eyewebs.be commented 1 week ago
@PC I don't believe it will work as-is for Belgium. Italy requires the use of the Sistema di Interscambio (SDI), which is different from Peppol, the system commonly used in Belgium.

Howdy!

In Romania e-Invoicing has been required for B2B since 1 January 2024 and B2C since 1 January 2025.

How do you handel this with WHMCS?
eyewebs.be commented 2 weeks ago
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.
PC commented 1 week ago
@eyewebs.be How for are you in developing this module?
eyewebs.be commented 1 week ago
@PC It's fearly easy to develop a module for this. And can be done in a short period. We are postponing development to wait for native support. Because the investment is not needed if WHMCS comes with native support. Or if we find interested users, we can share the investment.

URGENT – Critical for Compliance & Business Continuity (Belgium-based Businesses)

As a Belgium-based business, we rely on WHMCS to manage our operations efficiently. However, a critical feature is currently missing, which must be implemented before January 1st, 2026, or we, along with many other businesses, will be forced to seek alternatives.

This is not a “nice-to-have” feature request—it’s a legal necessity for businesses in Belgium. Without these crucial updates, running a business on WHMCS will become impossible under Belgian law.

We urge WHMCS to prioritize this immediately or risk losing a significant customer base in Belgium/EU/others.

We look forward to your response and a concrete roadmap for implementation.

I created my own electronic invoicing module for Italy, I think it would be a good idea for you to do the same.
Jorge commented 1 month ago
Unfortunately, the only way to solve this is going to be to use an external invoicing system that complies with the legal requirements.
jose antonio vazquez quian commented 1 month ago
It is essential to add this feature, otherwise we will look for another alternative.

Hi,

Spanish community is worried about this integration. Is there any news from WHMCS?

Thank you.
Riosecoweb Hosting commented 2 months ago
At the end of 2025 the Spanish government is going to force us to integrate our systems with verifactu.
https://sede.agenciatributaria.gob.es/Sede/iva/sistemas-informaticos-facturacion-verifactu.html

It is important to know what plans whmcs has with this because if we do not implement anything we will be forced to migrate to another billing system for our servers.
Antonio Mateos Galán commented 2 months ago
Hello team,

In Spain, it will also be mandatory starting from July 1, 2026, and additionally, the accounting software used must be certified by our tax agency. Do you plan to certify WHMCS for Spain?

It would be important for all Spanish providers working with WHMCS to know this in advance, at least to confirm if there is an intention to do so. Otherwise, we would need to look for alternatives that allow us to comply with our country's regulations.

Thank you.

In Belgium too ! Some news from WHMCS ???

@WHMCS

For the transmission of invoices, transition periods apply, particularly for businesses issuing invoices in the B2B sector.

1. Transition Period until December 31, 2026
Until the end of 2026, businesses may continue to send “other invoices” (e.g., PDFs via email) as long as the recipient explicitly agrees.
Legal Basis: Section 14 (2) Sentence 2 of the German Value Added Tax Act (UStG).

2. Mandatory E-Invoicing from January 1, 2027 for Large Businesses
From January 1, 2027, businesses with an annual turnover exceeding €800,000 in the previous year must issue and transmit invoices as e-invoices in the XRechnung or ZUGFeRD format.
Legal Basis: Section 14 (2) Sentence 3 UStG.

3. Mandatory E-Invoicing from January 1, 2028 for All Businesses
From January 1, 2028, all businesses, regardless of their annual turnover, are required to create and send invoices as e-invoices.
Legal Basis: Section 14 (2) Sentence 4 UStG.

What Does This Mean for Us as a B2B Business?

Since we deal exclusively with B2B customers, this regulation directly impacts us.

- A standard PDF invoice may only be sent with the recipient’s consent.
- If the recipient refuses consent, there are two options:
1. Mandatory e-invoicing (XRechnung/ZUGFeRD).
2. Sending a paper invoice.

Indirect Obligation as of January 1, 2025

These new regulations imply that we must start preparing by January 1, 2025 to ensure smooth operations. Recipient refusals of PDF invoices are expected to increase significantly.
Rico Rothenburger commented 17th December 24
We already have customers who prohibit us from sending PDF invoices.

You could buy the billing extension add-on module from katamaze or develop a similar one because this module works in all countries integrated with whmcs without external software. The problem with this module is that it has poor support otherwise it would be the best module on the market.
tomb commented 22nd August 24
Yes, E-invoicing will be mandatory in Germany on January 2024. Any development on this or do have to switch away from WHMCS?
Official Response
WHMCS commented 17th December 24
Hi tomb,
The timeline for Germany for e-invoicing to become mandatory are 1st Jan 2027 and 1st Jan 2028 for the majority of WHMCS users. This is according to the official source: https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eInvoicing+in+Germany
Jurgen Michiels commented 20th August 24
Indeed, the whole EU is making in mandatory to add UBL invoices between B2B and B2C accounts.
So it's getting quite urgent.
Otherwise, it's bye bye WHMCS.
