In the event the ERP API server is down (such as pricing or inventory availability) and you use real-time calls on your site, customers are still able to use **Add to Cart** functionality throughout the site, but are unable to check out.

Specifically, the following functionality is available during this scenario:

- Home page and general content navigation
- Signing into the site and selecting a customer
- Registration
- Search (auto-complete and regular search)
- Product list page
- Product detail page
- Order history
- Invoice history
- If A/R is in place and the service is down, desire to hide the Aging information
- Orders are able to be saved if cart already in place, but not checked out
- Add to List
- Add List to Cart 
- Quick Order 
- Saved order recall to cart
