Overview

Quaderno Connect is a powerful API and set of tools used to add tax management and invoicing features to business models like marketplaces and software platforms.

For example, if you are a marketplace, you can use Connect to add sales tax calculations to your checkout forms or record transactions (paid sales or refunds) on behalf of your merchants. But it’s not just marketplaces that work great with Quaderno - we’ve seen partner integrations built with all kinds of software from tools to manage sport clubs to WordPress blogs.

Every partner integration is different, so this document can’t tell you exactly what to do, but we’ll explain the flows you should handle, and give you some ideas of how to provide the best experience for your users.

Quaderno Connect is only available with the Business plan or higher.
