Numeral
Sales tax automation platform
Hands-off sales tax compliance for ecommerce and SaaS teams
Reviewed by The Desk · Last verified July 2026
“Numeral is one of the strongest hands-off sales tax tools for venture-backed ecommerce and SaaS startups: transparent $75-per-filing pricing, genuine automation, and human tax experts who actually field state notices for you. Just watch the math — because it is not SST-certified, per-return fees stack up as your multi-state nexus footprint grows.”
Skip it ifYou already have nexus in many states and file frequently — at $75 per return with no SST certification, costs climb fast versus CSP-certified vendors, and enterprise-grade needs (API, international VAT, exemption certs) push you into opaque custom Pro pricing.
What it is
Numeral is a sales tax compliance platform built for US ecommerce and SaaS businesses that want to stop touching sales tax entirely. It automates the full lifecycle — monitoring economic nexus, registering for permits when thresholds are crossed, calculating rates, filing returns, and remitting payments — across all US states and 80+ countries. The pitch is "fewer than five minutes a month," and for its target customer that is close to accurate.
Under the hood, Numeral pairs AI-driven workflows with a human tax team. It connects to platforms like Shopify, Stripe, Amazon, QuickBooks, and NetSuite to pull transaction data, then reviewed filings go out on schedule, and a virtual mailbox scans and responds to state tax notices on your behalf. Pricing is refreshingly transparent and per-event ($75 per filing, $150 per registration) with a genuinely free monitoring tier and no subscription lock-in — a contrast to the credit-and-overage models common in this space.
The company is well-capitalized and credible: founded in 2023, Y Combinator-backed, and funded with $57M across seed, a Benchmark-led Series A, and a Mayfield-led Series B, serving 2,000+ brands including Ridge, Eight Sleep, Brex, and Character.AI. The main caveats are structural. Numeral is not an SST Certified Service Provider, so per-return fees apply even in the 24 SST states that CSP vendors file for free — which means costs scale meaningfully for sellers with wide multi-state nexus. And several advanced capabilities (tax API, exemption certificates at scale, international VAT) live behind custom Pro pricing, introducing cost uncertainty as you grow.

Pros & cons
The good
- Transparent per-filing pricing with no long-term contracts or subscription lock-in
- Genuinely hands-off, with responsive human tax experts who handle state correspondence
- Penalty guarantee if a filing misses its deadline
The catch
- Not an SST Certified Service Provider, so per-filing fees are charged even in the 24 SST states that CSP vendors cover free
- Advanced features (tax API, exemption certificates, international VAT) are gated behind custom Pro pricing
- Per-event costs scale with filing volume and can get expensive for businesses with broad multi-state nexus

How much does Numeral cost?
Numeral charges $75 per filing and $150 per registration on its Standard plan, with a free monitoring tier and no long-term contracts. Advanced needs like API access, exemption certificate management, and international VAT sit on a custom-priced Pro plan.
Is Numeral an SST Certified Service Provider?
No. Because Numeral is not certified under the Streamlined Sales Tax program, filings in the 24 SST member states are billed at the standard $75 per return rather than being covered free as they would be with a CSP-certified vendor.
Who is Numeral best for?
It fits growing ecommerce and SaaS businesses — especially DTC brands and startups on Shopify, Stripe, or Amazon — that want to fully offload sales tax without hiring an accountant or managing filings in-house.
Does Numeral handle international sales tax and VAT?
Yes. Numeral supports VAT and indirect tax compliance across 80+ countries, but international coverage is part of the custom-priced Pro tier rather than the published Standard plan.
