Is it possible to charge a user based on traffic this user have used, for example: if this user used 10 GB traffics then in the end of month this user will be charged 10 GB * Price ?
I think auto top up covert this feature.
Yes, I thought that too. But the invoice will look ugly because hundreds of 1GB top up transactions.
2 ways of solution:
- Sell per 5,10,20,100 GB
- I think it is possible to aggregate these items in invoice without any problem.
