Quaderno

Overview

The Quaderno integration connects RevKeen with Quaderno's tax automation platform to handle sales tax, VAT, and GST compliance across jurisdictions. Instead of manually calculating tax rates, generating compliant invoices, or tracking registration thresholds, Quaderno handles tax logic automatically for every transaction processed through RevKeen. This is the recommended approach for businesses selling internationally that need to stay compliant without adopting a Merchant of Record model.

Features

The integration automates the tax lifecycle from calculation through reporting:

• Automatic Tax Calculation -- For every checkout, RevKeen calls Quaderno to determine the correct tax rate based on the customer's location, the product type, and the applicable tax jurisdiction. Supported tax types include EU VAT, UK VAT, US state and local sales tax, Canadian GST/HST/PST, Australian GST, and more. Tax is calculated in real time and displayed to the customer before payment.

• Tax-Compliant Invoices -- When a payment completes, Quaderno generates a tax-compliant invoice or receipt that meets local requirements. This includes proper tax identification numbers, reverse charge notations for B2B EU transactions, and jurisdiction-specific formatting rules. These invoices are accessible from the RevKeen dashboard and can be sent to customers automatically.

• Threshold Monitoring -- Quaderno tracks your sales volume by jurisdiction and alerts you when you are approaching or have crossed a tax registration threshold. This helps you stay ahead of compliance obligations in new markets rather than discovering them after the fact.

• Tax Reporting -- Access consolidated tax reports showing how much tax you collected, in which jurisdictions, and for which periods. These reports simplify tax filing whether you handle it yourself or pass the data to your accountant.

• B2B Reverse Charge -- For EU business-to-business transactions, the integration automatically applies reverse charge rules when the customer provides a valid VAT ID. The VAT ID is validated in real time during checkout.

VAT Operations Pool

RevKeen shares a global VAT API allowance across all tenants:

• Pro plan: 450 VAT operations per month per tenant
• Unlimited plan: Unlimited per-tenant (subject to global 1,000 ops/month pool)
• Standard plan: Not included

A VAT operation is allowed if: tenantRemaining > 0 AND globalRemaining > 0

Why Use Quaderno with RevKeen

RevKeen's Payment Service Provider model means you -- not a platform -- are the merchant of record. This gives you full control over your customer relationships and pricing, but it also means tax compliance is your responsibility. Quaderno bridges that gap:

• Stay compliant -- Correct tax rates applied automatically based on customer location and product type
• No MoR lock-in -- Get the tax compliance benefits of a Merchant of Record platform without surrendering your customer relationships or paying 4-5% platform fees
• Multi-jurisdiction -- Sell globally with confidence that each transaction has the right tax treatment
• Audit ready -- Every tax calculation is logged with the inputs and outputs for full traceability
