Adding Taxes Automatically from a third party app

Hi! I’ve figured out how to automatically add taxes when checking out through the Square app. But when I use my booking system, which is separate from Square, it doesn’t add taxes. Does anyone know how to do that or if it’s even possible?

Eg. I will ‘raise sale’ through my booking system (Timely) and select Square as the payment type. It takes me to Square to check out but the taxes aren’t added.

Whereas, when I just use the square app to checkout, it adds the taxes automatically for me.

I’m trying to avoid switching between apps.

Hey @Kelly_DGroomer,

Welcome to our community forum! I noticed it's your first time writing in 🙂

After looking into this a bit further, it doesn't look like there's currently a workaround that would allow taxes to be applied when a third party app, such as Timely is used. I've passed this onto our partnerships team as feedback as I can see how frustrating it would be to have to switch between apps.
