Any of Quaderno's 24 actions, including Create Contact, Create Estimate, Create Expense and Create Invoice. Your agent maps the data both ways and tests every scenario before it ships.

Do I have to build a connector for Mollie or Quaderno?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Mollie and Quaderno without building an automation?

What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
