When it comes to customization, WHMCS does this well. Whether you want to adjust the look and feel of your billing area (template, theme), make a simple adjustment to how things are handled, or add some complicated functionality, WHMCS can likely be modified to fit what you need.
We’ve been working with WHMCS since 2007 and have developed a number of addons and customizations to WHMCS. Some have been released publicly, some for private customers. If you need something done, please do let us know and we’ll work with you to get your project done.
We cannot provide custom quotes via the chat system. Any requests to do so will be sent to the contact form. While we do understand that you may want an instant quote, there are quite a few reasons why this is not feasible.
We do strive to provide thorough and effective estimates, which is why we recommend waiting 24 hours. If you haven’t heard back from us by that point, please do drop a mail to contact at whmcs dot guru and we will be in touch with you.
