What is economic nexus?

A connection based on specified economic activity, such as sales or transactions, rather than only physical presence. The test, period, exclusions, and obligations must be checked for the relevant jurisdiction and business.

How can software track a threshold?

A platform may ingest transactions, map activity, monitor exposure, and flag possible registration or filing. Anrok lists nexus monitoring; Numeral lists nexus monitoring; Kintsugi lists exposure monitoring. These are product descriptions, not legal determinations.

Does monitoring mean registration?

No. Monitoring, calculation, registration, filing, and remittance are separate. Confirm what the vendor performs.

Which listings mention nexus or exposure?

Avalara lists broad tax/compliance coverage; Anrok lists monitoring through exemption certificates; Numeral lists US sales tax/VAT/GST compliance and Concierge; Kintsugi lists exposure monitoring; Taxwire lists nexus/taxability study and managed autofile/remit; Sphere lists registration through remittance to 100+ tax authorities.

Are prices comparable?

Not from the roster alone. Anrok has per-market anchors; Avalara and Taxwire are described as sales-led/no public SKU dollars. Verify quote and scope.
