Numeral is an AI-native sales tax and VAT/GST compliance platform used by more than 3,000 businesses, including Brex and Supabase. Its AI agents run daily checks on government tax portals and classify products for taxability, automating nexus tracking, registrations, filings, and remittance across every US state a business operates in.
About Numeral
Founded in 2023 by CEO Sam Ross and CTO Matt DuVall, a former Stripe and Notion engineer, Numeral pairs AI agents with human tax support to handle US sales tax and international VAT/GST compliance. More than 3,000 companies, among them Brex, Supabase, Fishwife, and Character.ai, rely on it instead of the spreadsheets and manual filing calendars that growing finance teams otherwise build in-house. Two AI layers sit underneath the product: one reads correspondence arriving at state and federal tax-agency portals so nothing is missed by mail, and another maps a seller's product catalog to the correct tax treatment without a manual SKU-by-SKU review. Together they drive automated nexus tracking, state registration, filing, and remittance. Numeral is built for finance and tax leads at multi-state ecommerce brands on Shopify or Amazon, and for founders and CFOs at venture-backed SaaS companies who trip a new state's economic nexus threshold as they grow. Its exemption certificate management and virtual mailbox suit accounting teams that need compliance handled without hiring an in-house tax specialist, and its Enterprise tier extends the same workflow to companies expanding abroad. Pricing runs three tiers: a free Monitoring plan, a usage-based Professional plan billed per filing and per registration with no long-term contract, and a custom-quoted Enterprise plan that adds international VAT/GST coverage, a tax calculation API, and access to tax attorneys. Numeral is web-based with no desktop or mobile app. Numeral has raised $57 million across three rounds: a Y Combinator-backed seed round in 2023, an $18 million Series A led by Benchmark in March 2025, and a $35 million Series B led by Mayfield in September 2025 that valued the company at $350 million. The company is based in San Francisco with about 110 employees as of mid-2026.
Pricing
Free Monitoring plan: nexus tracking and threshold alerts across all US states, no cost. Professional plan: $75 per filing, $150 per registration, billed month-to-month with no contract required. Enterprise plan: adds VAT/GST coverage in more than 70 countries, a tax calculation API, and tax attorney consultation, custom-priced after a sales call.
Key Features
- AI nexus monitoring: Tracks a company's sales activity against every state's economic and physical nexus thresholds and sends an alert the moment a new one is crossed, before any tax obligation is missed.
- Autofile and Autoregister: The Professional plan automates filing, remittance, and state registration end-to-end, replacing a manually maintained calendar, and bills per filing and per registration rather than a flat fee.
- AI product classification: An AI layer assigns taxability codes to a merchant's product catalog automatically, so tax rates are applied correctly across jurisdictions without manual product-by-product mapping.
- Daily AI portal monitoring: AI agents check state and federal tax authority sites each day for notices, letters, and account changes, and route them to a virtual mailbox instead of relying on paper mail.
- Global VAT/GST coverage: The Enterprise plan extends compliance support to more than 70 countries with a tax calculation API and consultation from tax attorneys.
- Native platform integrations: Connects directly to Stripe, Shopify, Amazon, QuickBooks, NetSuite, Xero, BigCommerce, WooCommerce, and Salesforce to pull transaction data automatically.
- Exemption certificate management: Collects, validates, and stores resale and exemption certificates so exempt sales are not incorrectly taxed during filing.
- Late-filing penalty guarantee: If an Autofile filing is late, Numeral pays the resulting penalty instead of the customer. Most rival platforms leave that risk with you.
Pros
- The Monitoring plan is free and runs a nexus study across all US states before a business commits to any paid filing.
- Late Autofile filings are backed by a penalty guarantee, transferring risk that most competitor platforms leave with the customer.
- Backed by $57 million from Y Combinator, Benchmark, and Mayfield, giving it more runway than most niche tax-automation rivals.
- Native integrations cover 9 platforms including Stripe, Shopify, Amazon, QuickBooks, NetSuite, and Salesforce, pulling transaction data without manual exports.
Cons
- Pricing is per-filing and per-registration rather than a flat subscription: filing monthly in 30 states runs about $2,250 a month before any registration fees, per Galvix's independent pricing breakdown.
- Enterprise-tier pricing for global VAT/GST coverage and API access is not published and requires a custom sales quote after a call.
- No SOC 2, ISO 27001, or GDPR compliance attestation is published on Numeral's public site as of August 2026, unlike larger rivals such as Avalara and Vertex.
- No desktop or mobile app; the product is web-dashboard only, so field or offline use isn't supported.
Frequently Asked Questions
How much does Numeral cost in 2026?
Monitoring is free. On the Professional plan, Numeral bills $75 for each filing it submits and $150 for each new state registration, month to month, no contract. Enterprise pricing for international VAT/GST coverage, the tax calculation API, and tax attorney access is quoted after a sales call.
Is Numeral free to use?
Yes. The Monitoring plan connects a business's sales channels and billing platforms to run a nexus study at no cost, tracking physical and economic nexus across all US states and alerting when a new registration threshold is crossed. It does not include filing, registration, or remittance, which require a paid plan.
What are the best alternatives to Numeral?
Avalara is the larger, more established option with deeper ERP integrations for enterprise-scale filers spanning NetSuite, Salesforce, and Microsoft Dynamics. Anrok focuses specifically on SaaS companies and their nexus rules. TaxJar suits small and midsize sellers on a lower-cost subscription model rather than Numeral's per-filing pricing.
How does Numeral compare to Avalara in 2026?
Avalara has a broader integration catalog and serves larger enterprises, typically on annual contracts. Numeral targets a lighter, faster setup for growing ecommerce and SaaS teams, charging per filing and registration with month-to-month billing and no contract, and bundles white-glove tax support into its Professional plan.
