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.

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

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.

Integrating your marketplace with Quaderno has the power to add huge value for your users, streamlining their business processes and providing a great experience.

A Standard Quaderno account is a conventional Quaderno account controlled directly by the account holder (i.e., your platform's user). Users with a Standard account have a relationship with Quaderno, are able to log in to their Dashboard, can use their Quaderno account on their own, and can disconnect their account from your platform.

You can prompt your users to create Quaderno accounts or allow anyone with an existing Quaderno account to connect to your platform.

Custom account holders do not have access to a Quaderno Dashboard, and Quaderno will not contact them directly.

You should probably use Custom accounts when:
