Core Features:

- Commission calculation
- Back office access for users
- Accept payments, manage subscriptions, handle recurring payments
- Payment/commission withdrawal options

Commission-related Features:
- Tiered commission calculation
- Commission withdrawal options
- Commission tracking

Ideal Skills and Experience:

I'm open to offers and suggestions. Once our service is up and running, I'm also interested in a long-term maintenance agreement.
