# What we call things

> A few things in LedgerUp go by more than one name. Here's what each one means.

<AccordionGroup>
  <Accordion title="What is a collections campaign?">
    Collections campaigns are what we mean by **automated collections**: the automated sequence of emails that chases customers for unpaid invoices, on the schedule you set. This is what we mean whenever we say **campaign** on its own. Elsewhere in the industry this is called **dunning**. Same thing.
  </Accordion>

  <Accordion title="What's the difference between a workflow and a campaign?">
    The workflow is the editor you build a collections campaign in, and the shape of the campaign itself. You'll find the campaign listed under Collections but edit it in the workflow builder. **Campaign** and **workflow** refer to the same thing from different angles.
  </Accordion>

  <Accordion title="What is a step?">
    One email in a collections campaign, with its own timing, wording and recipients. A campaign is a series of steps.
  </Accordion>

  <Accordion title="What is an automation?">
    A procedure Ari runs whenever a trigger fires, separate from collections campaigns, and used for everything else you want handled automatically.

    <Note>
      Automations were previously called **Ari tasks**, and you'll still see both names in places. They're the same thing.
    </Note>
  </Accordion>

  <Accordion title="What are nodes?">
    The pieces an automation is built from, arranged left to right.

    | Node                  | What it does                           |
    | --------------------- | -------------------------------------- |
    | **Trigger**           | Starts the run.                        |
    | **Agent Step**        | Where Ari does the work.               |
    | **Decision / Filter** | Picks one route out of several.        |
    | **Post in Slack**     | Publishes the result and ends the run. |
    | **Silent Completion** | Ends the run without posting.          |
  </Accordion>

  <Accordion title="What is a trigger?">
    Two meanings, depending on where you are. In an **automation**, the trigger is the event that starts a run, an invoice paid, an email received. In a **collections campaign**, the equivalent is a step's overdue condition.
  </Accordion>

  <Accordion title="Who or what is Ari?">
    The AI agent inside LedgerUp. Ari works in the web app and in your shared Slack channel, and does the work you grant it permission to do.
  </Accordion>

  <Accordion title="What does 'payment pending' mean?">
    The badge on an invoice where a customer has told you payment is on its way. Behind it sits a **payment remittance** record, which is what you create and remove.
  </Accordion>

  <Accordion title="What is AR aging?">
    The accounts receivable view that groups unpaid invoices by how long they've been outstanding.
