I run a Shopify app that lets merchants sell digital event tickets. Nothing is shipped. Hundreds of my customers, including dozens of Shopify Plus stores, have a major pain point where they are unable to "always collect tax no matter what" on their products/events. Especially for merchants who border a non-tax state such as Oregon or Montana, as these states are not present in Settings > Taxes > add state.
It's a simple need... "always charge this X% tax on all products sold, regardless of any other factors". Is there a way?
I know about the 'legacy tax system', but Shopify support is no longer willing to enable it.
