1. Add products for share hosting and domains / add products for fibre and wireless internet
2. This WHMCS system is not automated I have do create share hosting and internet accounts so customers must not be able to upgrade with out approvile from me.
3. All billing must be done on the 1st of every month for all customers so if I add a new customer and add a product WHMS must bill that customer prorata to the 1st of the next month (Subscription billing).
4. Check security
