Sales tax, filed automatically, in every state where you sell. Stop hand-filing returns.
If you sell across state lines, you have sales tax obligations in places you have never visited. We monitor your nexus thresholds through your existing Stripe and Shopify accounts, register you where required, calculate what you owe, and file every return. One dashboard, one invoice, every state.
How it works Connect once. We handle the rest.
From nexus detection to monthly filing, end to end.
Connect Stripe + Shopify
One-click OAuth integration. We read transaction volume and customer state distribution; we never see your customer payment details.
Free nexus assessment
Within 60 seconds we tell you which states you already owe in and which states you are approaching threshold for. Free, no signup required.
Authorize registration + filing
Pick the states you want us to handle. We file the registrations within 5 business days; first returns due 30-60 days later depending on state schedule.
Monthly returns + audit support
We file every required return on the schedule each state requires. State fees pass through at cost. Audit support included on Multi-state Standard tier and above.
A clean handoff, in four steps.
You give us the basics. We handle the state, the IRS, and the compliance clock so you can focus on the business.
A name that's actually available.
Real-time check against the state register, USPTO trademark database, and matching domains.
Filed with the Secretary of State.
We submit your Articles, pay the state fee on your behalf, and return the stamped certificate.
EIN + the right tax setup.
Federal Employer ID with the IRS, plus state tax accounts when your business needs them.
Registered Agent + deadline tracking.
Your agent on file in every state, with every renewal and annual report tracked in one calendar.
Honest per-state pricing.
You only pay for states where you have active filing obligations. Stop selling in a state, stop paying for it.
