Bigcommerce error: ‘The quantity specified is greater than the quantity of the product that is available to ship.’

If you are getting the above error message, this means the inventory in your Bigcommerce store needs to be increased. In order to do that, simply login to your Bigcommerce account and increase the inventory amount for the product(s) that you are trying to ship.

As soon as this amount is increased, you can go ahead and ship them again and everything should work accordingly.
