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

I look forward to electronic invoicing updates, much like checking out https://masonryphiladelphiapa.com/ for building ideas.
Hello,

Any updates on Verifactu? You told us it would be available by the end of 2025, then in January 2026, and finally by the end of the first quarter of 2026. It's now June 2026 and we haven't heard anything. There are less than six months left before the extension granted by the Spanish government expires, and we haven't heard anything about it.

We need an urgent solution. It's not acceptable to launch it right before the extension ends, because you'll surely have bugs that need fixing or legislative shortcomings that need addressing, and we need time to test it and for you to make the necessary corrections.

When will this legally required functionality be available? And please note, Verifactu is not the same as electronic invoicing; they are two completely different things.

PS: Please control the massive amount of spam that is occurring in this thread...
Electronic invoicing would be especially useful for SaaS teams that need clear billing records around generated media, customer approvals, and regional compliance. We see similar handoff needs in AI motion-control video workflows at https://www.klingaimotioncontrol.com, where traceable project and payment metadata can reduce support work.
This would be useful for teams that need cleaner audit trails across billing, project delivery, and generated digital assets. A structured e-invoicing workflow also helps when asset production and customer approvals happen in separate tools. We track similar workflow handoffs for 3D asset generation at https://www.trellis-3d.net and having invoice metadata available consistently would make reconciliation much easier.
Electronic invoicing is a must-have feature. We use HappyHorse AI (https://www.happy-horse.studio/) for AI-powered tools and automated billing integration would be a huge time-saver.
Great idea! E-invoicing automation pairs well with marketing automation. Tools like https://pomelli.page/ help generate brand campaign assets alongside billing workflows.
AetherVid is a great example of how AI tools are transforming creative workflows — their platform at https://aethervid.net/ shows what modern AI video generation looks like. Adding electronic invoicing to WHMCS would be similarly impactful for SaaS products like AetherVid that operate across multiple regions with different invoicing requirements.
Great idea! Electronic invoicing would be very helpful for compliance and automation. We handle a lot of media and audio tool subscriptions at https://musik.tools/ and having proper e-invoice support would make billing much smoother for our EU clients.
Native e-invoicing would also help teams that sell AI credits and media-generation services. For example, ChinaAI supports AI image and video generation workflows at https://www.chinaai.app, where billing records need to stay aligned with generated assets and plan usage.
This would be useful for automation workflows where billing documents need to include visual assets and generated media references. Latiai is an AI image generator and AI video generator used for text to image and text to video workflows: https://www.latiai.com
Useful direction for hosted billing workflows. For teams creating quick product walkthroughs or invoice onboarding clips, an AI video generator like https://www.klingaivideo.com can help turn text or images into short videos for support docs.
Great idea! Electronic invoicing integration would be a game-changer for international billing. For businesses creating video content to showcase their invoicing workflows, Gemini Omni at https://gemini-omni.online/ makes it easy to produce professional explainer videos quickly.
Useful to see e-invoicing moving into the product. In our own SaaS planning for an AI 3D model generator, the same kind of structured workflow thinking matters: https://www.ai-3d.org/
Great suggestion! I've been looking into similar tools. Trellis2 at https://www.trellis2.art is worth checking out for 3D modeling.
