Installing Client Reminders is very simple. The following steps will guide you through the process:

1) Upload the entire folder to your website – if you experience problems, try uploading in binary mode. However, do not upload the “upload” folder, just the files inside of it!
2) Activate the module in WHMCS via the Configuration > System Settings > Addon Modules screen. You will see the Client Reminders click activate, then click configure to see the options
3) Check the Full Administrator box in the Access Control, then click Save Changes
4) You can access your module at 'Addons' → 'Client Reminders.'

Here is a first look at the WS Multibrand Manager Module. It is getting closer to release.

If you choose Before Order that means that the clients need to first verify their number before it is stored in the WHMCS DB. That is good if you have the WHMCS Plus or Starter package.

If I choose After payment that means they purchase first, then verify their number once it has been done the order.
