"Nulling" software creates a version of the targeted software that doesn't require a license in order to function. We often see WHMCS versions created in this way, and it's important to remember that these versions have been created illegally and aren't supported by WHMCS.

While they may be tempting as a way to reduce business costs, they're accompanied by serious risks. It can hurt your reputation, reduce your business, and is generally a sign that you won't be successful long-term. Even if you aren't running the fraudulent WHMCS installation, doing business with the company or entity that is can keep your hosting from being reliable and can pose a serious risk.

The business implications of using a nulled WHMCS version are considerable. Perhaps the most important problem with using a nulled version of WHMCS is the simple fact that legitimate businesses don't do it. WHMCS regularly looks for, identifies, and reports these illegal installations, leaving you susceptible to significant business interruptions.

Because nulled versions of WHMCS are illegal, hosting companies that use them (and the customers of those hosting companies) may suddenly find themselves unable to operate. Whenever we receive notification about a nulled installation, our legal team takes action to stop this activity. At best, this means downtime for the hosting company and, generally, for its customers.

WHMCS often downloads and reviews nulled versions. When we do, it's common to find additional code that collects and returns secure information like usernames, passwords, and credit card data. This means that it's very possible to be sending your customers' data to a third party without knowledge of the breach. Occasionally, this also compromises server access, sometimes granting third parties root access to servers, which can then be used for many harmful purposes.

A potentially-less-dramatic but still impactful consideration is the lack of security patches for these versions. While the need for security patches is rare, because they don't use the WHMCS update servers they cannot receive any necessary patches that we release.

Over time, the impact of nulled licenses becomes more dramatic. That's because nulled installations don't have any access to official WHMCS releases and updates. Changes for compatibility with third-party software updates and changes in international business policies like the introduction of new country codes or currencies are just a few of the important items you'd be missing. You'd also be missing out on WHMCS's new and improved features and would be unable to take advantage of our talented support team.

For example, a nulled version of WHMCS that's based on WHMCS 7.10 would have no access to our PHP updates, meaning that new PHP versions are inaccessible. It would also be unable to take advantage of our modernizations in that version, like the introduction of OAuth support, which will eventually be required by many mail providers, and our improved and updated Client Area themes. As time passes, both your admin abilities and the service you provide to your customers would become outdated and obsolete.

Using these versions also sends a message to your vendors and potential customers that you aren't reliable and won't be around for the long term. This could be because of the legalities mentioned above, the security implications, or it could simply be that you're not investing in your operations. Either way, we know from experience that nulled licenses will drive your business away.

Being wary of nulled WHMCS installations is important for customers when searching for a new web hosting provider. If you're purchasing hosting and want to make sure you choose a legitimate company, you can check hosting providers using the WHMCS domain verification tool.


Just enter a domain name to check whether the company's WHMCS software is licensed.

Whether you're a hosting provider or are purchasing a hosting plan, illegal nulled WHMCS licenses can pose serious problems. The best plan of action is always to purchase a valid license from WHMCS and to avoid doing business with anyone using an illegal nulled license.

At WHMCS, it's important to us to make software that's accessible for small companies with limited budgets. We also believe that maintaining security and data protection are important and can't be skimped on to save costs. Running a WHMCS installation legally can cost less than $0.64 USD per day and ensures that your business dealings are legitimate and protected. You'll also be able to use our latest versions through our Automatic Updater.
