Numeral review 2026: AI-native sales tax automation for e-commerce and SaaS. See nexus monitoring, filing and remittance features, pricing and alternatives.
Numeral is an AI-native sales tax compliance platform founded in 2023 by former Stripe and Notion engineers Sam Ross and Matt DuVall, and headquartered in San Francisco. The company went through Y Combinator and has since raised approximately $57 million in total funding, including a $35 million Series B led by Mayfield in 2025.
Numeral automates the full US sales tax lifecycle for e-commerce and SaaS businesses, from nexus monitoring and registration through tax calculation, filing and remittance, positioning itself as a done-for-you alternative to manual compliance processes or traditional tax software.
Numeral's nexus monitoring engine tracks transaction volume and revenue against each state's economic nexus thresholds and automatically triggers registration once a business crosses a threshold, removing the need for finance teams to track this manually across dozens of jurisdictions.
Its tax calculation API integrates with platforms like Stripe, Shopify, Amazon and NetSuite to apply correct sales tax at checkout, while its filing and remittance service prepares and submits returns on the customer's behalf, backed by a guarantee to cover penalties and interest for any late filing caused by Numeral's error.
Numeral prices per transaction based on the number of tax registrations and filings a business requires, rather than a flat monthly SaaS fee, and does not require long-term contracts.
Exact pricing depends on the number of states a business is registered in and its filing frequency, so prospective customers typically get a tailored quote after sharing their transaction volume and jurisdictional footprint.
