The Module:

This server provisioning module will allow our resellers to order new products from ourselves (white-label) and to provide these services to their customers. Coupled with our self-service PBX service, resellers are able to manage all of their 'tenants' on-the-fly.

About Giant:

We built Giant around offering UK communication services. With a long history of using WHMCS with our sister company, we understand the benefit of developing provisioning modules for WHMCS to help with our own service deployment. The majority of the telecommunication industry do not offer a 'ready-to-go' service provisioning to their wholesale customers, resellers or end-users. Giant aims to tackle all of these issues and build as forward-thinking reseller solution.

Notice: A valid Giant reseller account must be applied and registered to allow use of this provisioning module.
