Numeral

Identity

• Founded: 2022 (YC W23 batch) per Y Combinator; "two-year-old company as of September 2025" per TechCrunch implies a 2023 public launch date. Likely incorporation-vs-launch split. [VENDOR-CLAIMED — https://www.ycombinator.com/companies/numeral, https://techcrunch.com/2025/09/18/numeral-raises-35m-to-automate-sales-tax-with-ai/]
• HQ: San Francisco, California. Specific address not on a public Numeral surface. [THIRD-PARTY — https://www.ycombinator.com/companies/numeral, https://sacra.com/c/numeral/]
• Legal entity: Not publicly disclosed in research-window surfaces.
• Funding: $57M total raised across Seed → Series B as of September 2025. Most recent: $35M Series B at $350M post-money valuation, led by Mayfield with Benchmark, Uncork Capital, Y Combinator, and Mantis participating, announced September 18, 2025. Series A: $18M in March 2025, led by Benchmark. [THIRD-PARTY — https://techcrunch.com/2025/09/18/numeral-raises-35m-to-automate-sales-tax-with-ai/, https://www.businesswire.com/news/home/20250918544776/en/]
• Headcount: ~100, single-sourced from YC company page as of September 2025; Crunchbase and LinkedIn-employee-count both returned 403 to the fetcher. [THIRD-PARTY — https://www.ycombinator.com/companies/numeral]
• Recent news (last 12 months):
• September 18, 2025 — $35M Series B at $350M post-money valuation; announces 2,000+ customers, $5B+ in processed transactions, 150,000 returns filed, 3.5x year-over-year revenue growth. [VENDOR-CLAIMED — https://www.businesswire.com/news/home/20250918544776/en/]
• March 5, 2025 — $18M Series A led by Benchmark. [VENDOR-CLAIMED — https://www.businesswire.com/news/home/20250305498838/en/]
• 2025 ARR trajectory — Sacra-reported $1M (2023) → $3.1M (2024) → $5M (2025) ARR. Single-source figure; not independently audited. [THIRD-PARTY — https://sacra.com/c/numeral/]
• Latent risk — G2 reviewers consistently split between "the support team walked me through everything personally" and "we waited months for a response on a state issue" — second pattern shows up when work stops being filing-template-and-remittance and starts being state-notice-back-and-forth. [THIRD-PARTY — https://www.g2.com/products/numeral-sales-tax-platform-numeral/reviews]
• Archetype: End-to-end sales-tax compliance platform for e-commerce and SaaS — bundles nexus monitoring, auto-registration, calculation, exemption certificates, filing, remittance, and virtual mail into one contract with on-time-filing penalty cover.

Total score: 70.6 / 100

Note on score reconciliation: Yardstick's D1 catalog currently lists Numeral at 78/100. This dossier-derived total of 70.6 is the rubric-scored result from the evidence below. The 7-point delta most likely reflects (a) a higher Sub-B score in the catalog that pre-credited the AI workflow without the LLM-provider qualification, and/or (b) a higher Compliance score that pre-credited the on-time-filing guarantee without discounting for the missing public SOC 2 surface. Both are defensible adjustments. The dossier reports both numbers honestly and surfaces the per-dimension reasoning so the catalog can be reconciled.

• Stage fit:
• Foundation (<40 readiness): yes — free Monitoring tier + $75/filing Standard is the lowest-friction way to take a single-state or three-state Shopify/Stripe seller from "we have nexus, now what" to a clean filed return.
• Pilot (40–59): yes — the typical Pilot buyer is a 5–10-state DTC ecom or SaaS seller with no in-house tax expertise, exactly Numeral's design center.
• Scale (60–79): conditional — at 15+ filing states monthly the per-filing math starts losing to Avalara/Vertex volume-tier pricing, and the support-quality long-tail risk gets bigger.
• Optimization (80+): no — enterprise-tax-determination buyers (manufacturing, energy, telecom, multi-entity consolidated) need tax-content depth, audit-trail completeness, and e-invoicing that Numeral does not target.
• One-line verdict: Best Foundation- and Pilot-stage end-to-end sales-tax compliance choice for a US Shopify or Stripe-billed seller crossing economic-nexus thresholds in a small-to-mid number of states, with the on-time-filing penalty cover and 23+ named billing/ecom connectors as the headline strengths and operational-support throughput at long-tail complexity as the bounded weak spot.

Headline numbers

Dimension scores

Rubric source: https://yardstickresearch.app/cohort/tax/ (7 dimensions; raw 0–4 per dimension; weights sum to 100).

Pricing detail

Source: https://www.numeral.com/pricing (cross-referenced with https://taxcloud.com/blog/avalara-alternatives/ and https://sacra.com/c/numeral/). All [VENDOR-CLAIMED] unless noted.

• Monitoring — $0: Audit-exposure and historical-liability monitoring, physical and economic nexus monitoring, state-crossing alerts, integrations with Shopify / Stripe / Amazon / Walmart and listed connectors. No filing, no remittance, no registration help.
• Standard — $75/filing + $150/state registration: Everything in Monitoring plus filing and remittance via Autofile and Autoregister, all 50 US states coverage, virtual mailbox for state correspondence, automatic tax-code classification, CSV import, white-glove support, on-time-filing penalty cover. Filings stack: a seller filing monthly in 20 states pays roughly $1,500/month in filing fees alone (per TaxCloud teardown). Some states charge a registration fee on top; most are free.
• Pro — custom pricing (revenue-percentage model): Everything in Standard plus exemption certificate management (50 certificates free, custom plans for 50+), API access (real-time tax calculation), voluntary disclosure agreements, named sales-tax expert support, global coverage across 70+ countries. Pricing only disclosed on direct sales conversation.
• Exemption certificate add-on: Up to 50 certificates included free at Pro; custom plans available beyond 50. Includes automatic validation, expiration tracking, renewal workflows; 20+ named integrations including NetSuite, Shopify, Stripe.
• Contract terms: No long-term contracts required; month-to-month billing.
• On-time-filing guarantee: "We guarantee your sales tax is filed on time, or we'll pay your penalties and interest charges." — https://www.numeral.com/legal/guarantee

Integrations

Source: https://www.numeral.com/integrations. 23+ named integrations as of research date.

• E-commerce: Shopify, Amazon, eBay, Walmart, WooCommerce, Checkout Champ, Adobe Commerce, Salesforce Sales Cloud, Oracle Commerce, Oracle Retail Xstore.
• Billing / subscription: Stripe, QuickBooks, NetSuite, Chargebee, Sequence, Orb, Zoho Books, Rillet, Tabs, Odoo, Campfire, Acumatica, JustPaid, Fulfil, Sage Intacct, Agentforce Commerce, Microsoft Business Central, Maxio, Xero, SaasGrid.
• HR: Rippling.
• API surface: REST API at https://docs.numeral.com/api-reference/introduction. Bearer-token auth. Tax-calculation endpoint at /tax/calculations. Versioned ("2025-05-12" default with B2B + multi-currency enhancements; "2024-09-01" prior). SDK languages, rate limits, and webhook capability not extractable in the research window — right-of-reply.
• Real-time calculation gating: Real-time tax calculation via API is gated to the Pro tier per TaxCloud's 2026 teardown. — https://taxcloud.com/blog/avalara-alternatives/
• Marketplace-channel coverage: Amazon, eBay, Walmart marketplace facilitator obligations supported as first-party connectors — addresses a documented Stripe Tax blindspot (multi-channel nexus tracking when sales happen outside the Stripe payment pipe).
• Depth caveat: Avalara's competitive teardown asserts "no native ERP connectors; API-only (highest tier)" — best read as depth-of-sync rather than absence-of-connector; the named connector list is the more authoritative source for whether the integration exists at all.

Editorial assessment

Numeral is the cleanest end-to-end answer in the tax cohort for a US Shopify or Stripe-billed seller crossing economic-nexus thresholds in a small-to-mid number of states. The product surface is honest: a free Monitoring tier that tells the buyer whether they actually have a problem, then a $75-per-filing Standard tier with an on-time-filing penalty cover that does what the marketing claims it does for simple cases. The named-customer list (Brex, Character.AI, Fishwife, 8Sleep, Graza, Ridge, Kitsch, immi) is real and recent, and the Series-B at $350M post-money corroborates the underlying customer-growth shape. The on-time-filing guarantee is unusual in this cohort and economically meaningful — for a single-state miss, the state penalty plus interest can easily exceed the annual Numeral fee.

The bounded weak spot is operational support quality on the long tail of state-notice complexity. G2 reviewers consistently split between "the support team walked me through everything personally" and "we waited months for a response on a state issue" — the second pattern shows up exactly when the work stops being filing-template-and-remittance and starts being state-notice-back-and-forth. For a Foundation-stage seller in 3–5 states, the white-glove model holds; for a Scale-stage seller in 20+ states, the math gets worse on both the per-filing cost and the support-throughput risk.

The second weak spot is the security-posture surface. /security and /trust 404, security.numeral.com renders only a heading, and no SOC 2 attestation date is publicly readable. A regulated-industry buyer (healthcare-adjacent ecom, financial-services SaaS) will gate purchase on the attestation. Numeral almost certainly has one and serves it under NDA via request-to-view; the public absence is a measurable friction.

Compared to the cohort leader, Anrok (rank 1 at 88), Numeral overlaps on e-commerce/SaaS positioning and beats Anrok on per-filing transparency and on the on-time-filing guarantee specificity. Anrok wins on SaaS-specific tax-content depth (B2B SaaS edge cases, exemption flows, customer-facing tax-display tooling). Compared to Avalara, Numeral wins on time-to-value, transparent pricing, and full-lifecycle bundling, but loses on enterprise tax-content depth, e-invoicing, customs/duties, and audit-trail completeness. Compared to Stripe Tax, Numeral wins on the entire post-calculation lifecycle (registration, filing, remittance) at the cost of explicit per-filing pricing Stripe Tax doesn't levy.

Revisit if any of these change: the Trust Center exposes a public SOC 2 date, support-quality G2 reviews stop splitting at the complexity boundary, the Pro-tier pricing model is published, or a third-party rate-accuracy benchmark across the long-tail country list is published.

Best for

• Stage: Foundation and Pilot. Conditional for Scale (per-filing math and support-throughput risk).
• Company profile: Series A–B DTC ecom and SaaS sellers in the $1M–$50M ARR band with no in-house tax expertise, crossing economic-nexus thresholds in 3–15 states, billing through Shopify, Stripe, Chargebee, or similar.
• Industry fit: Strong for DTC / ecom and B2B SaaS. Moderate for FinTech, retail-health DTC, marketplace operators, global ecom. Not the fit for manufacturing / industrial / multi-entity-consolidated enterprises that need use-tax, customs/duties, manufacturing-exemption complexity, or e-invoicing.
• Tax-team profile: Zero-to-one in-house tax (CFO or finance lead with no dedicated tax hire).
• Annual tooling budget: $2K–$30K at Standard; $30K+ at Pro depending on revenue band.
• Skip if: You need (a) enterprise tax-determination depth across manufacturing/energy/telecom, (b) e-invoicing automation, (c) auditable proof of SOC 2 / ISO 27001 before a procurement signature without an NDA, (d) full bidirectional record-level NetSuite or SAP sync (vs. the lighter pull-for-filing pattern), (e) per-filing costs to stay flat past 15+ filing states monthly, or (f) named-LLM model lineage for compliance-team due-diligence.

Right-of-reply

Numeral received this tear-sheet seven calendar days before publication of the Yardstick Research 2026 Yardstick Report, including all measured numbers, sample outputs, and editorial assessment. Numeral was given the opportunity to flag factual errors — incorrect pricing, misquoted feature availability, outdated screenshots, factual misstatement in the editorial assessment. Numeral was not given the opportunity to request a score revision, dispute the rubric or its weights, withdraw from inclusion, negotiate ranking placement, or suggest changes to the editorial assessment beyond factual correction. Where the vendor flags a factual correction, the correction will be applied if verified and noted here; where the vendor disputes scoring, the dispute will be recorded but the score stands. Silence during the right-of-reply window will be treated as no objection.

Right-of-reply gaps

The following items are [UNKNOWN] in the dossier and are the concrete questions to put to Numeral during the factcheck loop:

• SOC 2 Type and last-audit date. Trust Center exists at https://security.numeral.com/ but the public-readable surface in the research window was the heading only.
• ISO 27001 status, if any.
• PCI DSS scope, if any.
• GDPR posture, including the sub-processor list and the EU data-residency option if it exists.
• Underlying LLM provider powering the AI workflow (rule-change ingestion, tax-mail handling).
• Pro-tier pricing band — typical revenue-percentage range, transaction-volume thresholds, percentage cap if any.
• Pro-tier real-time tax-calculation API rate limits and SDK language coverage beyond the documented /tax/calculations endpoint.
• Founding year reconciliation — YC company page says 2022; TechCrunch's "two-year-old company as of Sept 2025" implies 2023. Likely incorporation-vs-launch split — vendor confirmation requested.
• Headcount corroboration — YC says 100; Crunchbase / LinkedIn-employee-count both blocked the fetcher. Vendor confirmation requested.
• Rate-accuracy benchmarks across long-tail countries (Tanzania, Kenya, other Pro-tier non-US jurisdictions named in TechCrunch coverage) — any internal QA-cycle data Numeral can share.
• Audit-trail / immutability-log specification — retention window, export format, customer-side accessibility.
• Independent pre-filing reconciliation workflow — Galvix asserts this is absent; Numeral's own description of the pre-file QA layer (human-in-the-loop vs. fully automated) would clarify.
• Support-throughput SLA for complex state-notice situations — G2 reviews surface a Foundation-fast / Scale-slow split that Numeral can address with a concrete SLA or by acknowledging the operational improvement target.
