What Quaderno does

Quaderno is a tax compliance software company that automates sales tax, VAT, and GST calculation, registration, invoicing, and filing for online businesses operating across borders. Its core product is a REST API-driven tax engine that draws on a proprietary database covering more than 12,000 tax jurisdictions worldwide and applies the correct rate to each transaction in real time based on customer location and product category. The product is modular, organized around Calculation, Registration, Reporting & Filing, Invoicing, Checkout, and Connect (a white-label engine for platforms and marketplaces), with an API layer enabling developer-led integration. The company integrates natively with major payment processors (Stripe, PayPal, Braintree, GoCardless, Square), e-commerce platforms (Shopify, WooCommerce, Amazon FBA), creator-economy tools (Kajabi, Thinkific, LearnWorlds, Teachable), and accounting systems (Xero, QuickBooks Online).

Quaderno generates revenue primarily through tiered monthly subscriptions ranging from $29/month (Hobby, 25 transactions) to $149/month (Growth, 2,500 transactions), plus custom enterprise pricing for high-volume accounts, and add-on managed services for tax registration paperwork and end-to-end filing. Its go-to-market combines a product-led growth motion (free trial, no credit card required, in-product onboarding) with an API-first developer channel and a direct enterprise sales motion for accounts above 2,500 monthly transactions. The customer base of 6,000+ businesses spans digital creators, e-commerce merchants, SaaS companies, platforms/marketplaces, and accountants, with Quaderno Connect enabling the company to embed inside larger platforms and reach sellers indirectly.

Founded in 2014 in Las Palmas de Gran Canaria, Spain, and bootstrapped/founder-led prior to acquisition, Quaderno was acquired by European business software group Visma in 2023 and now operates as a subsidiary within Visma's portfolio, leveraging Visma's security and operational infrastructure. The company processes 13 billion+ transactions annually and maintains 4.5+ ratings across Trustpilot, G2, and Capterra.

Core offering

Quaderno provides a worldwide tax compliance SaaS platform for online businesses that automatically calculates sales tax, VAT and GST on every transaction across 12,000+ jurisdictions, monitors economic nexus thresholds, handles tax registration paperwork, generates tax-compliant invoices in the customer's language and currency, and files tax returns on the customer's behalf. The offering is delivered through a modular product suite (Registration, Calculation, Reporting & Filing, Invoicing, Checkout, Connect) plus a REST API, targeting SaaS firms, e-commerce merchants, digital creators, platforms/marketplaces and accountants.

Product overview

Quaderno is a modular worldwide tax compliance platform for online businesses. The core platform centers on a tax calculation engine that covers over 12,000 jurisdictions globally and handles sales tax, VAT, and GST. The product suite is organized into distinct modules: Registration (automated threshold monitoring and tax jurisdiction registration), Calculation (real-time tax rate application), Reporting & Filing (tax return generation and automated filing), Invoicing (automatic tax-compliant invoice generation), Checkout (embeddable tax-calculated checkout flow), and Connect (white-label tax engine for marketplaces/platforms). An API product provides developer access to all core capabilities. The modules are designed to work together as an end-to-end compliance solution but can also be used independently based on business needs.
