    Three steps to a running Invoiless workflow

    The builder keeps the order you think in: connect the app, choose what starts the workflow, add what should happen.

    1. Connect

      Authorise Invoiless once

      Add a Invoiless connection under Connects and reuse it in every workflow. Credentials stay in your WordPress database.

    2. Trigger

      Pick what starts it

      Start from a Invoiless event, or from a WordPress event, a form, a webhook, a schedule or any of the 918+ integrations, then capture a sample so later steps can map real fields.

    3. Act

      Add Invoiless steps and logic

      Chain Invoiless actions with Router, Filter, Iterator and Delay, test each step against captured data, then switch the workflow on.
