30## Sales Tax {#sales-tax}

32Zed partners with [Sphere](https://www.getsphere.com/) to calculate indirect tax rate for invoices, based on customer location and the product being sold. Tax is listed as a separate line item on invoices, based preferentially on your billing address, followed by the card issue country known to Stripe.
