Who Numeral is best for
Online sellers new to nexus
The free Monitoring tier builds a nexus study from connected stores or billing platforms and alerts when a new jurisdiction is reached, before any filing fee.
Small sellers with few filings
Pay-as-you-go pricing at $75 per filing means a seller registered in a handful of states pays per return, not a flat monthly platform fee.
Teams on Shopify, Stripe or NetSuite
Numeral lists those and other platforms as connections, so transaction data can feed the nexus study without a manual export of order files.

What Numeral does
- Nexus monitoring
- Tracks physical and economic nexus automatically and alerts when a new jurisdiction is reached, so a seller learns about an obligation before the filing deadline passes.
- Calculation, filing and remittance
- Automates U.S. sales tax, VAT and GST calculation, filing and remittance. A pay-as-you-go fee applies to each filing on the Professional tier, and registrations are charged separately.
- Registration and mailbox
- Autoregister handles registration across U.S. states, and a virtual mailbox is included on Professional for the paper notices that tax authorities send to a registered business.
- Certificate management
- Manages exemption certificates with real-time, AI-powered validation, which reduces the manual review a team does each time wholesale buyers send in new certificates for checking.
- AI product classification
- Professional lists AI product classification beside exemption management, meant to assign taxability to catalog items. The pages read do not describe accuracy or a review step.
- Natural language reporting
- The homepage names natural language reporting among its AI features, letting a user ask questions about tax data in plain words instead of building reports by hand.
How Numeral handles your data
The privacy policy covers website and marketing data only and says customer data is governed by customer agreements, so whether customer data trains AI models is not stated on the pages read. No retention periods are given; personal data is deleted or de-identified when no longer reasonably necessary for its purpose, unless law requires longer. The websites are hosted in the United States, and personal data may be processed in any country where Numeral or its providers operate. No certification such as SOC 2 or ISO 27001 appears in the policy, and the security page was not reachable.
Where Numeral falls short in practice
- Global coverage is quote only. Coverage in 90 or more countries, the tax engine and the API appear only on Enterprise, with no price shown. A seller with mostly European VAT work cannot size the cost from the pricing page.
- Customer data terms are elsewhere. The privacy policy addresses website data only and points to customer agreements for platform data. A buyer must read the agreement or a data processing addendum to learn about AI training and hosting.
- Per-filing fees add up. At $75 per filing, a seller filing monthly in many states pays for each return, and registrations cost $150 each. Compare against flat-rate platforms once the number of filings per year is known.

Alternatives to Numeral
Numeral: common questions
How much does Numeral charge for filings?
The Professional tier charges $75 per filing and $150 per registration, pay-as-you-go. The FAQ says there is no setup fee for standard U.S. filings. The Monitoring tier is free, and Enterprise is quote only. Count your filings per year across states before comparing with flat-fee tools.
Is Numeral monitoring really free?
The pricing page lists Monitoring as free. It covers a nexus study from connected stores or billing platforms, ongoing monitoring of physical and economic nexus, alerts for new jurisdictions and audits of past exposure. Registration, filing and remittance work moves you to the Professional tier and its per-filing fees.
Which AI features does Numeral name?
The vendor names continuous government portal monitoring, AI product classification, natural language reporting and real-time AI-powered certificate validation. The pages read give no accuracy figures or describe a human review step, so test classification on a sample of your own catalog before relying on it.
Does Numeral cover VAT outside the United States?
The features list names U.S. sales tax, VAT and GST. Global coverage in 90 or more countries is listed only on Enterprise, while Professional covers U.S. states and jurisdictions. Ask which countries are included and whether filing, not only calculation, is offered for each.
Does Numeral train AI on customer data?
The pages read do not say. The privacy policy covers website and marketing data and says customer data is governed by customer agreements. Ask for the data processing agreement and a written answer on AI training, hosting region and retention before connecting a store or billing system.
