One thing I’d add is to plan the support/refund rules before launching.
With SMM panels, customers usually do not get upset because an order is slow once. They get upset because they do not know what is happening. So I’d set rules before taking orders:
- what counts as “started”
- what counts as “completed”
- when refill applies
- when partial refund applies
- how long a customer should wait before opening a ticket
- which services are risky or non-guaranteed
I’d also avoid selling every cheap service you can connect by API. A smaller menu with clear labels is easier to manage. For example: fast start, refill available, no refill, low drop, high quality, mixed quality, etc.
The backend/provider side matters, but the customer-facing rules matter just as much. If your panel explains expectations clearly, you will get fewer angry tickets even when a provider has delays.
