All The Latest Release News, Insider Insights, Guest Posts and more from the team here at WHMCS

WHD Global 2014


This week we attended and exhibited at 2014 - the world's largest annual hosting event.

This was our first time exhibiting at a conference in Europe, and so it was great to get to meet so many of our European users, many for the first time, and many of whom we've been working with and talking to for years.

If you missed it, we've uploaded some pictures from the event to our official Flickr account.

Conferences are always a great opportunity to connect with users of our product, and to talk with customers about what we've been working on, and what you can expect to see from us in the coming weeks and months. And right now we really have a lot to talk about - there's our automatic update utility (which by the way is now super close to entering public beta status), as well as deeper cPanel integration, and an all-new fully responsive mobile (and tablet) friendly client area theme.

I'll soon be reaching out to members of our beta community about this, as one thing that attending conferences always re-confirms for us, is that our users really care about what we do, and we love that and want our users to be involved so we can benefit from all of your experiences and ideas. The new theme is way more than just a fresh coat of paint too, and so right now we're demoing and working on it with some of our closest partners, so stay tuned for more on that.

There's a lot more we're working on too, but I can't reveal all just yet... maybe if you come and hang out with us in Miami at HostingCon, we might just be able to let you in on it then :)

WHMCS Welcomes it's Newest Partner: ModulesGarden


In the past few months, we ceased offering custom development services to allow us to focus more directly on core product development and specifically projects that have a broader benefit to our entire customer base.

Being accessible and easily extendable to developers is one of the key things that has helped WHMCS get to where it is today. And so in doing this, it was very important to us that we still had a solution that we could offer to clients for customising their WHMCS installation - from creating reports, to creating custom modules and hooks, to adding whole new functionality.

And that's where ModulesGarden comes in. ModulesGarden have been doing custom development work for WHMCS since 2011 and they've worked with some big names - OpenSRS and OnApp to name just two. We've also been recommending them for some time now, and the feedback we have been getting from clients who have used them has been very positive.

So today we are pleased to announce we have now created a formal partnership with them. ModulesGarden is our preferred development company, and we are proud to recommend them for all your WHMCS customization needs. Custom Development Services offered by ModulesGarden include:

  • Custom Gateway Module Development
  • Custom Registrar Module Development
  • Custom Provisioning Module Development
  • Custom Addon Module Development
  • Custom Reports
  • Custom Hooks
  • Custom Theme Development

To celebrate this partnership, ModulesGarden will be joining us at our booth at World Hosting Day 2014 in Rust, Germany all next week, to talk with clients about custom module development and how we can work together to create additional functionality for your installation of WHMCS.

So if you're needing custom development work, be sure to check out their page in our partners area @

WHMCS Insights: Client Service Status Filtering

Something you might have missed in the recent 5.3 release was a feature that provides the ability to filter a clients products, services, addons and domains on the Clients Summary page.

Now you might be thinking why do I want this, and if you are, here's a couple of scenarios to consider...

  • Imagine you have a client with lots of products/services, and you want to prorate all of their active services to bill on the same date. Well now it's easy, instead of having to look through the entire list, ticking the individual checkboxes next to just the active items, now you can simply filter for Active services, check all, and perform the mass action.
  • Now take the same scenario but this time you have a client who has multiple suspended products, simply filter for suspended items, check all and again perform a mass action to unsuspend them.
  • And even consider a situation where you're a support technician and you just don't need to see items with a fraud or pending status - those being there slow down you finding what you really need, and so it would be great if they just didn't show up there in the first place, and now you can do just that.
So, how do you use it... Begin by visiting the Client Summary page for a client and about half-way down, on the right hand side, you should see a new Status Filter button (if you don't, make sure you updated those templates when upgrading:

By default the filter will be Off, and the button will reflect this. But click it and you'll see the statuses you can choose from.


Toggle the checkboxes for any of the statuses and hit apply and you'll see the button change to green to indicate a filter is applied, and the lists update in real-time to show only the services matching the statuses you have selected.


And what's more, any filters you apply persist for the duration of your session and so if you apply a filter, and then navigate to another client, that same filter will still be be applied.

Want to remove the filter again? Simply open the filter options, tick the "Check All" box and hit apply. Simple as that.

I hope you'll find this as much of a time saver as I already am.
