SMS Center For WHMCS is an innovative module created to enable sending text messages to administrators and clients. To this end, it features over ten separate SMS gateways plus another one meant for testing purposes. By means of these, the module will let you verify new customers and orders as well as enable two-factor authentication which will oblige your clients and staff members to use SMS codes in order to log in to the system.

Thanks to our product you will be able to create SMS templates corresponding to specific email templates in your WHMCS, both default and custom ones. Each text message comes with predefined content but if needed, you can edit it suitably or even add other versions in different languages. What is more, you may inform your staff about certain products, domains or addons orders as well as important tickets being opened - just compose the text message template and define the recipient conditions. Of no less substance is the ability to assign gateways to certain countries as well as define templates for mass SMS messages which then can be sent at your discretion in accordance with previously set recipient filtering. At any moment, you will be able to manage the list of queued SMS and check the status of each text message to make sure it has been delivered.

Your clients will get the permission to select which of the notifications they wish to receive or even turn them all off. Apart from the notifications, customers may receive tokens which will have to be used to finish the process of account or order activation. For their convenience, the module allows them to request the tokens to be sent again.

SMS Center For WHMCS is a perfect enrichment for your business communication. Order it now to keep both your administrators and clients well informed wherever they are!
