# Mapping Business Units to sub-classes in QBO - recommended workflow

## Things to know

- You cannot make payments or create invoices if the business units associated with the payments or invoices are not active in ServiceTitan. Business units deactivated in ServiceTitan will cause issues when exporting since the system does not recognize transactions tied to deactivated business units. Before exporting, make sure the business units associated with your transactions are active.

## Workflows

### Workflow

To map Business Units to sub-classes in QuickBooks Online:

1. Navigate to Settings in ServiceTitan.
2. In the search field search for Business Units. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/mapping-business-units-to-sub-classes-in-qbo---recommended-workflow-image-w6feapns.png)
3. Select the Business Unit you would like to map > Click on **Edit**. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/mapping-business-units-to-sub-classes-in-qbo---recommended-workflow-image-dgb5oedo.png)

5. Enter the name of the subclass with a colon. Click **Save**. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/mapping-business-units-to-sub-classes-in-qbo---recommended-workflow-image-mjeixfuz.png)
6. In QuickBooks Online navigate to **Settings** > **All Lists** > **Classes** and navigate to the subclass. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/mapping-business-units-to-sub-classes-in-qbo---recommended-workflow-image-gcy2mie0.png)

8. You will see that, in this example, Install is a subclass of Electrical. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/mapping-business-units-to-sub-classes-in-qbo---recommended-workflow-image-84j47j5g.png)
9. If Install was not a sub-class of Electrical, you would want to check the box and click **Save**.
10. On the invoice now, it should look like this with **Category:Subcategory**: ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/mapping-business-units-to-sub-classes-in-qbo---recommended-workflow-image-7jrmdd21.png)
