Nexus sneaks up. We don't let it.
NexusRadar tracks your trailing-12-month sales and transaction counts against every state's economic nexus threshold — and reminds you about filing deadlines before they bite.
The problem: economic nexus sneaks up on sellers
Every state sets its own economic nexus threshold — usually around $100,000 in sales or 200 transactions, but the details vary. Cross one and you may owe registration, collection, and filing in a state you've never set foot in.
Unfiled nexus routinely means back taxes, penalties, and interest once a state audits — and states are getting aggressive with marketplace data.
Meanwhile the incumbents meter you to death: TaxJar's 2026 pricing is $39/mo plus $50–55 per filing. A 10-state quarterly filer pays $500+/mo in filing fees alone, with unpredictable spikes.
The radar + flat-rate filing
NexusRadar watches all 50 states + DC against your actual sales. At 80% of a threshold you get an 'approaching' alert; cross it and you know immediately — with a plain-English note that says talk to your CPA, not a black-box conclusion.
Filing deadlines get reminders at 30, 14, 7, and 1 days. Everything exports to a CPA-ready CSV.
And the Filer tier includes 5 state filings per month at a flat $49 — no per-filing meter.
