Quaderno is a Tax Compliance service. The app that has been built is a generic invoicing app. The primary API endpoints that are needed for tax compliance are:
https://developers.quaderno.io/api/#tag/Tax-Rates
https://developers.quaderno.io/api/#tag/Tax-IDs
https://developers.quaderno.io/api/#tag/Tax-Jurisdictions
https://developers.quaderno.io/api/#tag/Tax-Codes
https://developers.quaderno.io/api/#tag/Reporting
Without these the Quaderno app is useless.
