Unavailable item



Technical Explanation:

This issue is caused by Olo attempting to commit an order that has an item on it that is no longer available in POS. This is often caused by items that have been set to "Unavailable" in POS after/since an order has been scheduled. 


Tuesday, an order is placed for a Steak with a Baked Potato for pickup on Friday.

When this order was placed on Tuesday, the database reflected that both the Steak and the baked Potato were available.

Since then, on Thursday, the restaurant ran out of potatoes and set all Baked Potatoes to Unavailable (using Aloha's Item Availability feature).

On Friday, when Olo attempts to commit the order to POS fails because Aloha has been configured such that the Baked Potato is "unavailable".

The response through Aloha Connect (COM) is the error code that ends in 26 when the scheduled order is fired to POS.


  1. Confirm the item has been replenished in-store
  2. Set to Available in Aloha's Item Availability feature.
  3. Run Price Updater in Olo
