Enterprise-Grade
WHMCS Management

Yes, you may change your package. However, this requires a full manual migration. We have to move your database to another tier infrastructure and redeploy your WHMCS to another server. During this period, we may prevent your clients from accessing your billing system. Therefore, this should be rare. We expect you to start with a package that is sufficient for your business for a year to come.

You may change the active clients limit on the same package whenever you want. We simply update your WHMCS license and resize your server instance. This is fast and easy.

WHMCS version 8 came out in 2020 and significantly changed how addon modules work. Our modules that come with Growth and Enterprise packages work with the WHMCS version 8 only. The Base package uses the standard WHMCS code, so we may install older WHMCS versions for this package.

We implement heavy optimisations for PHP 7.4 and 8.1. WHMCS versions prior to 8 do not support these PHP versions. Therefore, we would run your older WHMCS versions on a standard PHP 5.6. This would significantly degrade your WHMCS performance.

We support WHMCS versions 6 and 7 on the Base package as a temporary solution. We may upgrade your WHMCS install with a custom theme and modules to the latest version in a few weeks.

We can do this for you. We do not provide clients with access to their production file system. We test all modules and themes that clients want on the staging environment. If we find no unacceptable risks, we push them to the production environment.

If you have developers that need to test modules, we may launch a development environment for you.

Several WHMCS modules allow you to manage website pages inside your WHMCS. Some clients require extensive publishing functionality and run a separate CMS on a different hostname, e.g. WordPress on the naked domain and WHMCS on the subdomain. Both of these cases are standard with all our packages.

We see a growing number of clients using static storefront pages that lead to WHMCS once the Add to Cart button is clicked. Static HTML pages load up to 10 times faster than simple WHMCS text pages. Combined with a public API component to handle AJAX requests (e.g. cart items, login status, language, etc.), this ensures a fluent visitor experience. Storefront visitors do not notice the transition between static HTML and WHMCS pages. Unified customer experience and speed are especially important to Enterprise clients that want to deliver thousands of page views per second. Static HTML pages generated using Jekyll or Eleventy (11ty) may be combined with WHMCS on the same hostname when running on the Enterprise package.

Running a PHP CMS like WordPress on the same server is possible, but it is not a standard practice. This would complicate your deployment and increase the risk of system conflicts (e.g. cookies). Such systems would start separate PHP sessions for the same visitor, which would prohibit you from providing your clients with a really unified experience anyway. We should look into such a case individually to understand what you are trying to achieve with such a configuration.

No. When it comes to security, it must be done right at every single step. To provide Sumfort level service, we need to have control over the whole infrastructure.

Our server providers have data centres in all regions. If you are concerned about latency or data storage laws, we may deploy your WHMCS in the location you prefer.

We do offer high-availability options for our Enterprise clients. Base and Growth packages are deployed on a simpler infrastructure. In case of a disaster, Base and Growth installations may experience short downtime during relocation.

Yes, you may migrate to any other hosting environment at any time. We do not lock our clients in technically and do not require any long-term commitment legally. You may simply download your WHMCS database, buy a WHMCS license and deploy it on your own server.

However, our Growth and Enterprise packages use proprietary modules that modify WHMCS core logic. Without these modules, your WHMCS installation would continue to function, but it would lose all these security and compliance features.

WHMCS is used by tens of thousands of service providers. Most of them are very small and feel comfortable managing the installation themselves. There is not much we can offer to them at any price point.

Service providers that have more than 1,000 and less than 10,000 active clients usually see sufficient value in keeping their WHMCS secure, fast, up-to-date, accessible and compliant. Our European clients pay us a small fraction of what it would cost them to develop and maintain such security and compliance in-house. Our relationships focus on enhancing clients' savings and earnings by providing more value, so discounting and simplifying our services is not in their interest.

Very few service providers exceed the standard WHMCS tier of 10,000 active clients. If you are one of them and feel our pricing does not work for you, we would like to talk to you and understand your situation.
