I have this same issue, already checked stock and I do have on hand. Where you able to find a solution?

Hi,
If  in the pos configuration stock configuration is real time, while validating the order, the related stock transaction, ie, stock picking will also get validated, if the stock is available.

If the stock is not available at that moment, then the order wont get validated and user has to manually validate the order. So just check and see if the stock is available in the store to validate the order.


Thanks
