Anrok

Modern B2B SaaS sales tax built post-Wayfair.

By Anrok, Inc. · Founded 2020 · San Francisco, CA · private

Anrok is the modern B2B SaaS-native sales tax platform, founded 2020 in San Francisco specifically to address the post-Wayfair compliance burden on US software companies. The company raised a $200M+ Series B in 2024 led by Sequoia and Khosla, valuing the company at roughly $1B. The product covers calculation, nexus monitoring, registration, filing, and audit defense, all designed around B2B SaaS revenue recognition (subscription billing, usage-based billing, prorated upgrades, multi-entity). Strengths: built natively for B2B SaaS workflows (the Avalara/Vertex generation was built for e-commerce and ERP), modern UX that finance teams actually like, the most-cited Avalara replacement in SaaS finance Slack channels, strong Sequoia/Khosla backing, and the deepest Stripe Billing / Chargebee / Maxio (Chargify) integration in the category. Best fit for venture-backed B2B SaaS in the $5M-$500M ARR band needing modern sales tax with nexus monitoring + registration + filing in a single product. Trade-offs: Narrower customer base than Avalara, audit defense depth still maturing versus legacy enterprise leaders, international VAT/GST coverage thinner than Avalara/Sovos, and pricing has crept up at the higher tier as the company moves upmarket.

  • “We left Avalara for Anrok in Q1. The migration took six weeks, the pricing is half, and the product was clearly built by people who actually understand SaaS billing. Avalara never knew what to do with our usage-based pricing.”
