How does your GBill System works?
You purchase a Bill package from our site. Upon receipt of confirmation by our merchant 2Checkout, your account will be created and a welcome email immediately send. The system is an online based Ticket system and runs entirely secure SSL. You can find the system here.
Tickets are being created (first new ticket only!) Online. Afterwards you can respond per email. The allocated and spend GBills (tickets) are visible once you are logged in and you will be able to see which GBills are used for what tickets and support you have requested. The packages are explained through the links you find in the menu in top.
Joomla’s flexibility and ease of usage makes it a popular CMS, which has resulted in a vast community and tons of extensions, only imagination can restrict the use of Joomla. Then why is Joomla sometimes operating with less speed than expected or slow? Joomla itself is not slow, one needs to tweak settings and use the available inbuilt options to boost up performance. Its up to the user to get the maximum out of joomla by tweaking settings and optimizing Joomla framework. Default Joomla has lot of potential to be optimized for speed and performance.
Often people require just a some specific support or just general support in finishing a project or purchase support valid for multiple sites. GWS-Desk provides this ad-hoc support on non Joomla core issues where needed. This relates for example to 3rd party software, extension setups and upgrades, etc. This is practical if you do not wish to purchase a support package but need a one-off assist.
