Payment after order confirmation

[AJlekceu]

Hello everyone.
Tell me how to implement the following:
1. Buyer add to basket
2. Places an order.
3. Store Administrator confirms the order
4. The buyer gets access to pay for the goods

How to make the customer to pay for the goods only after podverzhdeniya administrator of the shop?
