Quaderno

Tax automation for digital businesses and small SaaS.

By Quaderno SL · Founded 2013 · Las Palmas, Spain · private

Quaderno is the digital-business sales tax automation platform, founded 2013 in Las Palmas, Spain. The product covers global tax calculation, invoicing, and reporting for digital businesses, info-products, courses, and small SaaS, with a particular focus on EU VAT, US sales tax, and Australian GST. Strengths: clean fit for solo and small digital businesses (course creators, info-product sellers, small SaaS), strong EU VAT compliance heritage, simple pricing model, and clean integrations with Stripe, PayPal, Shopify, Gumroad, ThriveCart, Teachable. Best fit for digital businesses, course creators, info-product sellers, and very small SaaS in the under-$5M-revenue band wanting simple global tax. Trade-offs: limited fit for B2B SaaS at scale (Anrok, Numeral, Avalara all better above $1M ARR), thin US sales tax depth versus Anrok or Avalara, smaller installed base, and product velocity has slowed since 2022.
