Support for escrow payments is planned for a future release of the theme (release date not yet confirmed), so this would manage payments as you have mentioned, however currently this is not implemented in the theme.
Escrow Support – Coming Soon!
Collect payments in a neutral escrow account and automatically distribute them upon project completion. That’s the power of escrow payments. PayPal Adaptive Payments is built-in and included for free. Support for other escrow payment gateways like Balanced Payments will soon follow.
There is no private messaging function within the theme. Thanks.
