Once you have finished adding products to a Tariff, you have to publish it in order to make it available to the retailer.
Warning
Once a tariff is published, you can no longer edit it or add products to it.
If you want to add products, create a new one with those products
If you want to edit a field, you will need to archive the tariff and create a new one from scratch.
