title: Is this possible with Magento?
body: <p>I want to create a <strong>private store</strong> (disable frontend user registration and guest checkout, only enable the option for the admin to add new users).</p>
  
  <p>I want to give the registered user the possibility to purchase items without paying at the checkout. I don't want to add products with the price set to 0.00, because at the end of the month I want to send them the invoice covering all the purchases for that month (and for that, I want the products to have the price).</p>
  
  <p><strong>It this possible with Magento?</strong></p>
  
  <p>Please let me know, thanks.</p>
