Is there anyway to make the billing address the same as shipping address

I just need to make it so that the customer can not use an alternate address as we can only ship to the billing address due to fraud.  Let me know how to do this please.  I have version 2.8.  Thank you!

...\Presentation\Nop.Web\Controllers\CheckoutController.cs

Probably best to set breakpoint(s) and step through code - e.g.

        public ActionResult BillingAddress()

I have this very same issue.  Can anyone help?  I'm using NOP 2.65.

I can upgrade without a problem to a later version.

That will require custom programming.
Or, Shipping Director can enforce this.  I've blogged about it at Billing & Shipping Address Must Be Same Over $X.  Just note, though, that it still requires that the customer choose the shipping address.  To skip selection of shipping address selection/page will require custom programming.

And finally done. Please see this commit
