About
Quaderno is a comprehensive tax compliance software designed for online businesses that sell globally. It removes the complexity of managing sales tax, VAT, and GST by automating every step of the compliance lifecycle — from registration to reporting. At its core, Quaderno monitors your economic nexus and VAT/GST thresholds in real time, alerting you the moment you have new tax obligations in any jurisdiction. It then applies the correct local tax rate to every transaction automatically, drawing from a database of over 12,000 tax jurisdictions worldwide. During checkout, taxes are calculated instantly without any manual intervention. When it's time to file, Quaderno can file returns on your behalf or generate detailed reports you can hand off to an accountant. The platform also handles automatic invoicing — sending branded, tax-ready receipts to customers immediately after each sale. Quaderno integrates seamlessly with popular payment and e-commerce platforms including Stripe, Shopify, WooCommerce, PayPal, GoCardless, and Kajabi, as well as offering a developer-friendly API for custom setups. It is suited for digital creators, SaaS companies, e-commerce stores, and platforms or marketplaces that need a reliable, scalable tax engine without building one in-house.
