What is Quaderno
Quaderno is a cloud-based tax compliance tool that calculates and applies sales tax and VAT, validates customer tax IDs, and generates tax-compliant invoices and receipts. It is used by online businesses—particularly SaaS, digital goods, and e-commerce sellers—to manage tax determination and documentation across jurisdictions. The product focuses on automating tax evidence collection, invoicing, and reporting via integrations and an API rather than providing a full general-ledger accounting suite.
Automated tax calculation and invoicing
Quaderno calculates applicable sales tax/VAT and can generate tax-compliant invoices and receipts for transactions. It supports workflows common to online subscriptions and digital sales, where tax rules vary by customer location. This reduces manual rate lookups and invoice formatting work compared with handling tax inside a general accounting tool.
Integrations and API-first workflows
Quaderno provides integrations for common payment processors and commerce platforms, plus an API for custom checkout and billing systems. This makes it practical for engineering-led teams that need tax determination and invoice issuance embedded in their own product flows. It can also centralize tax documentation across multiple sales channels.
VAT ID validation and evidence
Quaderno supports VAT number validation and captures location evidence used for cross-border VAT/GST rules. This helps businesses document why a specific tax treatment was applied and supports audit-readiness for digital services. The product also produces tax reports that can be used to prepare filings or share with advisors.
Not a full accounting system
Quaderno is primarily a tax compliance and invoicing layer, not a complete accounting and finance suite. Businesses still typically need separate software for general ledger, AP/AR management, and financial statements. This can add integration and reconciliation work for finance teams.
Filing and remittance may be limited
While Quaderno produces reports and documentation, end-to-end managed filing and remittance services are not its core focus in the way some larger compliance platforms operate. Organizations with high transaction volumes, many registrations, or complex nexus/permanent establishment needs may require additional tax advisory or filing support. Requirements vary by jurisdiction and entity structure.
Complex tax scenarios require setup
Edge cases such as mixed taxable/non-taxable bundles, marketplace facilitator rules, exemptions, and multi-entity operations can require careful configuration and ongoing maintenance. Some scenarios may need custom development using the API and additional controls outside the product. Teams should validate coverage for their specific jurisdictions and product types during evaluation.
