# Step 1: Create an Object

Create an Invoice Statement object from the user interface.

After you create a PushTopic and subscribe to it, you’ll get notifications when an Invoice Statement record is created, updated, deleted, or undeleted. You’ll create the object with the user interface.

1. From your management settings for custom objects, if you’re using Salesforce Classic, click **New Custom Object**, or if you’re using Lightning Experience, select **Create** | **Custom Object**.

2. Define the custom object.

   - In the **Label field**, type `Invoice Statement`.
   - In the **Plural Label** field, type `Invoice Statements`.
   - Select **Starts with vowel sound**.
   - In the **Record Name** field , type `Invoice Number`.
   - In the **Data Type** field , select `Auto Number`.
   - In the **Display Format** field, type `INV-{0000}`.
   - In the **Starting Number** field, type `1`.

3. Click **Save**.

4. Add a Status field.

   1. Scroll down to the Custom Fields & Relationships related list and click **New**.

   2. For Data Type, select `Picklist` and click **Next**.

   3. In the Field Label field, type `Status`.

   4. Type the following picklist values in the box provided, with each entry on its own line.

      ```nolang
      Open
      Closed
      Negotiating
      Pending
      ```

   5. Select the checkbox for **Use first value as default value**.

   6. Click **Next**.

   7. For field-level security, select `Read Only` and then click **Next**.

   8. Click **Save & New** to save this field and create a new one.

5. Now create an optional Description field.

   1. In the Data Type field, select `Text Area` and click **Next**.

   2. In the Field Label and Field Name fields, enter `Description`.

   3. Click **Next**, accept the defaults, and click **Next** again.

   4. Click **Save** to go the detail page for the Invoice Statement object.

   Your Invoice Statement object should now have two custom fields.
