This is what a nexus study answers. We connect to your revenue systems (Stripe, Shopify, NetSuite, QuickBooks, BigCommerce, ChargeBee — and CSV for anything not native) and consolidate transactions into one ledger tagged by ship-to state. Against that, we run state-by-state nexus on both economic thresholds (typically $100k in sales OR 200 transactions, with California and New York at $500k) and physical signals (employees, inventory, 3PLs). The output is a current state-by-state position plus an alerting threshold so you see new states approaching nexus before you cross — including the case where a single large invoice into a state can breach the threshold on its own.

Foreign qualification is a corporate-registration concept, not a tax-nexus concept — and the two get conflated routinely, including by some AI research tools. Physical nexus comes from offices, employees, or inventory; a foreign qualification by itself doesn't trigger it. We audit your existing registrations against actual nexus, separate the ones tied to real activity from the ones filed unnecessarily, and produce a deregistration plan for the states where you don't owe — handling trailing nexus and any open liabilities before closing each state so cleanup doesn't create a new gap.

Yes — we cover indirect tax across 70+ countries, including registration, filing, and remittance. For EU sales, OSS via the Netherlands or Ireland is usually the cleanest path for non-EU sellers; OSS doesn't cover Norway, Switzerland, or Iceland, which need separate registrations. UK MTD-compliant submission is supported through NetSuite, Xero, and QuickBooks integrations. ANZ GST, Mexico VAT, and most major EU countries are direct; we use vetted local partners for markets requiring local credentials. One portal, one calendar, one team handling filings — replacing the country-by-country email and manual currency-handling drudgery.

Stripe Tax calculates tax at Stripe checkout. It doesn't register you in states, file your returns, manage exemption certificates, handle international VAT/GST registration, or cover any revenue that doesn't flow through Stripe (NetSuite invoices, Shopify, HubSpot deals, ticketing platforms, marketplaces). We handle the full lifecycle — registration, calculation, exemption certificates, filing, remittance — across every revenue channel. Many customers actually run our integration alongside Stripe Tax during transition, then retire Stripe Tax once the lifecycle is on us. The real choice isn't calculate-vs-calculate; it's checkout-only-vs-full-compliance.

Yes — and we see this often. A default tax code meant for tangible goods applied to a software or service product can cause you to collect and remit tax that wasn't actually owed, creating false liabilities and overpayment. We review your product catalog, re-map every SKU to the correct classification (e.g. "custom B2B software downloadable" instead of TPP), and stop the bleed going forward. For prior periods, several states allow refund or credit claims within their lookback window — we identify what's recoverable and pursue it where it's worth pursuing.
