We are developers and have now an app published. The app is about Text Marketing, merchants can send messages through it.
So, let's see the situation:
1. Merchant tops up, get some money on the balance, send 1000 messages (we spent this money, cos we need to pay to our SMS operator)
2. If the Merchant is a cool guy, he will pay his invoice and we will see money on our payout (in a month maximum)
But. If the Merchant is a bad guy, he can just delete the app without paying, after sending 10000000 messages.
How can we be safe in such situation?
Is there a secret, people?
