WHMCS 9.0 has just gone generally available, and it met us right in the middle of ongoing work. Testing environments were already running, internal checklists were open, and real use cases were being verified one by one. This is the rhythm we have learned to trust over the years. Because whenever WHMCS takes a step ahead, we are right there with it, without waiting for the dust to settle!
A number of our modules are fully tested and confirmed to work smoothly with WHMCS 9.0, including well-known favorites: cPanel Extended For WHMCS, Discount Center For WHMCS and Proxmox VE VPS & Cloud For WHMCS. And several more are right behind them in the final stages! Each update reflects results you can rely on, coming from real testing and real scenarios that mirror how our community uses WHMCS every single day.
WHMCS 9.0: Reading the direction
As every release, version 9.0 comes with responsibility and understanding that behind every WHMCS installation, there are people running businesses, supporting clients, and solving problems in real time. When our clients upgrade their WHMCS installations, they expect the ecosystem around it to be ready. Our role has always been to make sure that expectation comes across as natural, almost obvious. That is why it helps to look at WHMCS 9.0 from two sides: what it changes for us, and what it brings for you.
What this release means for us
From our point of view as module developers, WHMCS 9.0 confirms a direction we have been expecting for some time. The platform keeps aligning itself more closely with modern PHP standards, clearer internal structures, and a more consistent technical foundation. Updated PHP and ionCube requirements raise the baseline for performance and security, while changes within the API open doors for more flexible and future-proof integrations.
WHMCS 9.0 also modernizes parts of its internal architecture, including framework components and dependencies, and for us, this is where much of the real work happens. These changes directly affect how modules communicate with WHMCS, how reliably they can evolve, and how future-ready the entire ecosystem becomes.
What this release means for you
From a user perspective, WHMCS 9.0 continues to refine the experience around billing, compliance, and automation. Improvements in areas like invoicing logic, VAT handling, and data imports make routine tasks easier to manage, especially for businesses operating across different regions, markets, and tax regimes. Neither of these may seem exciting at first glance, but each will surely prove its value once it becomes part of daily operations.
Overall, WHMCS 9.0 feels like a solid step toward a cleaner, more scalable platform. One that gives developers better tools and gives users more confidence that their systems are built on something designed to grow with them.
So, what’s next for the WHMCS modules?
Whenever a new major WHMCS version appears, the same practical questions tend to follow. WHMCS 9.0 is no different, and we know well that having things clearly explained makes all the difference.
How can I tell if my module is safe to use with WHMCS 9.0?
As testing moves forward, we make sure to share clear updates on compatibility through the main channels, such as our weekly newsletter. For those who like to stay a bit closer to the updates, we also share a few additional places to drop by regularly. As soon as a WHMCS module has successfully passed all checks, it can be found at:
- Our Marketplace, in a dedicated section filtered specifically for WHMCS 9.0 support.
- Our Forums, where we maintain an up-to-date list of modules confirmed to work well with WHMCS 9.0.
How do I update my module for WHMCS 9.0?
Once compatibility is confirmed, updating follows the standard process you already know. Want to walk through it again? A step-by-step guide to updating WHMCS modules is available on our Wiki.
What if a module has not been tested yet? Can I still use it?
Technically, it might work, but we do not recommend relying on chance. WHMCS 9.0 introduces changes that can radically affect how modules behave, even if everything looks fine at first glance. Waiting for confirmed compatibility is the safest path, especially in production environments.
What about custom modules built for earlier WHMCS versions?
If your WHMCS installation includes tailor-made solutions created through our custom software development services, WHMCS 9.0 is a good moment to give them some extra attention. The new release brings meaningful internal updates, so it is worth verifying that everything still fits together as smoothly as before. If you would like a second pair of eyes or some expert guidance, just reach out to us. Our team is always happy to take a look together with you.
WHMCS 9.0 is officially here, and for us, it already feels like home territory. We work early, we test carefully, and we do it with the community very much in mind. That has always been the reason behind our pace. If you have questions about WHMCS 9.0, module compatibility, or custom development, our Support Team is always ready to help. Because when WHMCS moves forward, we believe the experience should be shared, supported, and easy to trust.
