SMS Center For WHMCS has been designed to let you send text messages to both your clients and staff members right from within your WHMCS. The module features support for over 80 SMS gateways, including the world’s favorite Twilio, Clickatell and FastSMS. With it, you will be allowed to verify new customers and orders, as well as establish two-factor authentication to access your system.

Our module will empower you to create easily editable SMS templates that correspond to specific WHMCS email templates, both default and custom ones. You will be able to send single text messages as well, simply through picking a customer or typing in any number manually. What is more, SMS Center For WHMCS will allow you to text your administrators upon specific events, e.g. when important tickets are opened. As another option, you can design templates for mass SMS messages and send them at any preferred time, following the adjustable recipient filtering. If needed, you will be allowed to regulate multiple configurations under every active SMS gateway, each dedicated to a different group of countries. Having all kinds of sent messages stored in the archive, you as well as your clients can quickly browse and review any notification whenever wanted. As an added benefit, you can text the customers via branded messages as soon as you integrate the module with Multibrand For WHMCS. Upon the combination with Client Profile Viewer For WHMCS, sending individual SMS messages will be possible from nearly any area of your WHMCS system.

At any moment, your clients will be free to decide whether or not to receive SMS notifications. Once they opt in, they will be allowed to select particular types of messages they would like to have access to. Text notifications can be also used to equip customers with tokens required to complete the process of account or order activation.

Go beyond the ordinary means of securing a rapid and efficient flow of information. Open up a new channel of customer devotion with SMS Center For WHMCS, and stay close to your audience anytime, anywhere!

    Having decided to start using SMS in my business I looked around and decided on this product that impressively met my requirements. Then on when loading the software of that I had issues :(, (of my own making, unknown at the time not Modules Garden fault), that required me to contact support help. The support team at Module gardens was impressively quick in supporting me, (taking into account the time zone diff), even though it was my fault they quickly diagnosed the problem and clearly reported back to me :) :)
    It is great to know there is good support backing a product.

    “ I love the ease of operation that SMS Center for WHMCS affords me! "

    I love the ease of operation that SMS Center affords me, in that I can update our customers quickly and easily right from my phone or WHMCS administration, and that I'm able to deliver a concise message to those participating in our SMS program. The back-end support & dashboard that SMS Center has in place is top notch. Anyone could use this SMS marketing service & succeed with their business goals. Text message marketing builds your contacts while getting your message directly into the hands and minds of potential customers.

    I have tried several others, and this one is the best! The GUI is simple and easy to use, not to mention it has a lot of gateways to choose from. A few other SMS sellers charge additional fees to add your preferred gateway but with this one "its a good chance yours is already listed." If you are looking for quality and great customer service "this is it - right here"!
  • 5 years ago
    Using SMS centre, we now can ensure when our clients have ignored or forgotten about a bill, they get an SMS, No excuses after that. The time saved in un-suspending customers and chasing them for payments based on the use of this module in invaluable.
  • 5 years ago
    This addon does an amazing job with providing our customers realtime updates and changes alerts to their SMS. Our customers feel much more at ease knowing when their invoices are coming up for renewal and their support tickets have unread responses.
  • 5 years ago
    This addon has changed how we do business. We spend so much less time chasing money from customers and more customers pay early or on time. Very worth while. Works very well.
  • 6 years ago
    We love this product, and in fact most of the products that we have bought from ModulesGarden.
    SMS Center For WHMCS has proved to be invaluable in delivering critical sms's to our clients and securing their accounts.

    ModulesGarden support is fantastic, and their modules are rock solid.
