The app is unusable for any Shopify merchant who has a base currency that is not USD... It assumes USD in the connection to Shopify, which makes the filing completely wrong (they could just read in the USD values from the order, but they didn't think to do such a simple thing). A spoke at length with the support team, who eventually just said they are aware of the shortcoming, but said it wasn't on their roadmap to fix it. So for now, we are doing manual imports to TaxJar which defeats much of the purpose of even using them in the first place. Looking at other reviews of this app, I can see TaxJar are not concerned with building a robust platform that actually works. Very poor service.

No way to connect this to the SANDBOX. If you want to test this, you will POLLUTE your live data.

*****BEWARE!! DO NOT USE TAXJAR!!! *****Charging us $30,000 in states sales tax when we really owe $300. RIDICULOUS!!! They will not help us amend this before filing. They will be stealing $30,000 from us that we don't have!! They also take days to respond and there are deadlines that they will not help before!

Consider this review a serious caution. I wish it were possible to rate this app with zero stars. The support team is virtually non-existent, and on the rare occasion you do receive a response, it's clear they lack any real understanding of their own service. We're currently paying $349 monthly for the Pro plan, which is set to increase to $499 next month. Additionally, they fail to offer SST service as they aren't a certified service provider, which is concerning given the seriousness of sales tax compliance and the risks associated with non-compliance. I strongly advise avoiding this service.
