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 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

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.

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

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.
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.
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.
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.
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
So it's getting quite urgent.
Otherwise, it's bye bye WHMCS.

In 2025 it will also be required in Belgium.
