Happy customers who stopped worrying about sales tax
I have been avoiding sales tax given that I have been heads down focused on my business. But I just spent 3 mins on the platform and I already understand my sales tax exposure.
What people ask first
We already use a tax tool. Why check again?
Keep it. This is a free second opinion on your own data.
Do we need this if we’re under every threshold?
Maybe not today. But staff and inventory count too, and checking takes five minutes.
What’s the catch?
None. Monitoring is free for good. Pay only if we register or file, from $75.
Will it touch my store?
No. The connection is read-only. Checkout stays as it is.
Is my data safe?
SOC 2 Type II and GDPR compliant.
