Manually review online orders before customers are charged

I’d like online orders to come in as “Pending Review” so we can verify details before the customer is charged.

Here’s the flow we need:

1. Customer places an order online.

2. Order is marked Pending Review and we get notified.

3. We review the order and confirm inventory.

4. If approved, we trigger the card charge.

5. If rejected, the order is canceled and the customer is notified.

This should be a client-level setting, so each business can choose whether to enable or disable manual review.
