1. What is quaderno and quaderno connect?

Quaderno is a tax calculator application that calculates tax automatically region-wise and it is globally available all over the world. We just need to pass the country to API’s then we will get the tax rate automatically. It provides tax calculation services for different types of businesses like SaaS, eCommerce, and digital businesses worldwide.

So we got the basic idea about quaderno, now depending upon business structure we need to select Quaderno APIs. If we want to use the tax compilation as your business owner then we can go through simple APIs, but if your business structure has multiple sellers and they are selling products and services on your platform, in this case, we need to use a different service provided by Quaderno known as quaderno connect.

Quaderno connect is used when you have a marketplace and if you have different sellers on your platform and they can add a tax id and they will get a tax rate.

There are different types of connected accounts 

  • Standard Account:

A Standard Quaderno account is a conventional Quaderno account controlled directly by the sellers of your platform and sellers are able to use quaderno dashboard and also able to login and control all functionalities. 

  • Custom Account:

A Custom Quaderno account is almost completely invisible to the seller. Platform owner is responsible for all interactions with your user and controlling all the account’s settings, also  Platform owner controls all the information needed for tax calculations, programmatically.

So in this tutorial, we will be going through the custom connected account integration.
