Checkout Assistance

I need assistance in customising the store to not take payments when "checking out" but rather submit an order so that we can confirm availability before taking payment.

Orders can only be submitted with payment. Squarespace Commerce doesn't allow payment cards to be vaulted and charged later. That said, if your product stock levels are correct, it shouldn't be possible for a customer to purchase an item that isn't available. 

Can you explain the situation further?
