Quaderno

Quaderno brings sales from storefronts, carts and payment gateways into a shared tax record. That transaction history supports tax calculations, registration alerts and reports by jurisdiction. Standard connections include Stripe and Shopify, while its application programming interface (API) supports custom checkout work.

What the Stripe connection does

Open Integrations in Quaderno, select Stripe and sign in on Stripe's own page. Choose Connect my Stripe account, then set up the tax jurisdictions where the business is registered. New payments generate invoices; refunds generate credit notes and update the reports.

The default connection receives the final payment amount and treats it as tax-inclusive. Adding tax on top at checkout requires an API integration or a platform that calculates tax before sending the charge to Stripe. Stripe Link with Checkout does not pass the customer's tax ID for this connection, so it cannot support its B2B invoicing flow.

Choose a transaction allowance

All plans offer a seven-day trial without a credit card. Ongoing software access is paid, with monthly and annual billing options.

A business with more than one Stripe account needs Startup or above. Stripe processing fees are not imported as expenses automatically; they can be entered as a monthly expense.

Reports and outsourced filing

Reports export to CSV or PDF for self-filing or an accountant. Buying Quaderno's filing service adds a monthly fee for each jurisdiction, even when the return itself is less frequent. For example, US filing is USD 70 per state per month with no setup fee. EU VAT OSS is EUR 100 per month, plus EUR 600 for a new registration or EUR 300 for a takeover.

Most filing services have no long-term commitment, but fiscal representation in certain countries has a separate annual fee and minimum term. Discuss the countries, sales volume and registration history with the team to get the full filing quotation.
