Most e-commerce businesses are non-compliant without knowing it

Sales tax law changed in 2018. The thresholds are different in every state. Most sellers only find out when a state sends a notice.

Economic nexus across 45 states

You can owe sales tax in a state where you have zero physical presence — purely from selling there. Thresholds differ by state and change without notice.

Annual report deadlines nobody tells you about

Miss your LLC's annual report and the state administratively dissolves your business — voiding your liability protection and contracts.

Privacy laws, FTC rules, and more

CCPA applies the moment you collect a California email address. CAN-SPAM applies to every promotional email you send. Most sellers have no idea.

Ervian's answer

Discovery first. Deadlines second.

Most compliance tools only remind you of deadlines you already know about. Ervian tells you about obligations you didn't know existed — then tracks them automatically.

Connect your Shopify store once. Ervian monitors your sales across all 50 states, fires a warning at 80% of every threshold, and automatically assigns the registration obligation the moment you cross it.

Built for small e-commerce, not enterprise

One flat price. No per-state fees. No usage tiers. Everything you need from day one.

Obligation Discovery
