Note: The Sellsy configuration is identical for all e-commerce platforms.

Enable your workflows

Once the Sellsy app is installed, you will be redirected automatically to this step.

Pay attention to the start date of your flows (by default, the date the connector is configured).

We recommend generating "drafts" rather than finalized invoices during the testing phase.

You can configure:

The document owner (by default, the user who configured Sellsy)
A document template
A pricing category
