Frequently Asked Questions

A Region is counted as any jurisdiction where you need to register and file taxes. In the US that is typically a state. Canada is comprised of 5 Regions (federal level GST / HST and 4 provinces that charge their own PST). EU is one region if you file via the One Stop Shop (OSS). The rest of world is typically by country.As an example, if you needed coverage in California and Colorado as well as in Germany, France, Australia and the UK, you would be charged for 5 regions (2 US states, EU, Australia and UK), totaling US$500 / month if you are on our Starter plan.

For high volume clients we do charge a flat fee / transaction once you go over 50,000 transactions across your active regions on Sphere. This is because we incur additional costs with high volume that we need to recoup. Additionally, some jurisdiction may have registration fees which we will debit your account for. Outside of that, we have no implementation fees and no additional one-off costs.

You can find a list of all the regions we currently service here - note that we add regions every week, so if there is one that you are looking for that is not listed, please reach out and we’ll let you know when it will be available.
