How It Works
Get set up in 5 minutes. No tax expertise required.
Connect Your Store
Connect Shopify or WooCommerce (other platforms are in beta) and upload Amazon order reports. Sails imports your orders, so there's no retyping.
We Track Your Sales
Sails adds up your sales into each state, compares them with that state's threshold, and flags the states you're approaching or have passed.
Know What To Do
See which states you may need to register in, your filing deadlines, and your sales and tax collected by state — ready for your returns.
Sound familiar?
"I sell on Shopify and Amazon but I have no idea if I should be collecting sales tax."
→ See your nexus picture across all 50 states and DC, with every channel combined.
"I'm scared I'll get a letter from a state saying I owe thousands in back taxes."
→ Spot the states you're close to or over — before a state spots them first.
"Filing deadlines are different for every state and I can't keep track."
→ See the upcoming due dates for every state you track on one calendar.
"I don't have time to figure out sales tax rules for 45 states."
→ We keep each state's thresholds up to date, with sources (last reviewed September 25, 2026).
