# Use Shopify Flow to adjust a customer’s points balance

> Automatically add or remove points from a customer's points balance using the Adjust points balance action in Shopify Flow.

The **Adjust points balance** action updates a customer's points balance as part of a Shopify Flow workflow. It uses the same fields as a manual points adjustment, but runs automatically when your workflow conditions are met.

<Note>
  **Note:** Not sure whether to use **Send Smile activity** or **Adjust points balance**? See [**Shopify Flow and Smile**](/en/articles/shopify-flow-and-smile).

  **Feature availability:** Shopify Flow actions are available on **Essential, Standard, Growth, Plus, and Enterprise** plans for merchants using Shopify Flow.

## How the action works

When you add **Adjust points balance** to a workflow, you'll configure three fields:

**Points** — The number of points that will be added or removed from the customer’s points balance. Use a positive number to add points, a negative number to remove points, or a mathematical formula to dynamically calculate the number of points to add/remove. Formulas can contain Shopify variables (e.g. `5 * {{variable}} + 2`), and any decimal values will be rounded to the nearest whole number. If you attempt to remove more points than a customer currently has, the action will fail.

**Description** — A note customers will see in their points history, such as **Bonus points for purchasing Product X**. You can use Shopify variables in this field.

**Internal note** — A private note for your records that customers won't see, such as **Part of summer promo campaign**. You can use Shopify variables in this field.

## Set up the Adjust points balance action

<Info>
  **Important:** Make sure the Shopify Flow app is installed in your store before continuing. You don't need to configure anything in Smile Admin before using this action.
</Info>

1. From Shopify Admin, go to [**Flow**](https://admin.shopify.com/apps/flow).
2. Click **Create workflow**.
3. Click **Select a trigger**, then choose your trigger.
4. Optional: Click the **+** icon, then choose **Condition** to add conditions to your workflow.
5. Click the **+** icon, then choose **Action**.
6. Search for **Smile**, then select **Adjust points balance**.
7. In the **Customer** field, the customer variable will automatically populate based on your trigger, such as `order.customer.id`.
8. In the **Points** field, enter the number of points to add or remove. Use a negative number to deduct points. You can include Shopify variables in formulas, such as `2 * {{order.subtotalLineItemsQuantity}}`.
9. In the **Description** field, enter the text customers will see in their points history.
10. Optional: In the **Internal note** field, add a note for your records.
11. Click **Turn on workflow**.

<Tip>
  **Tip:** Use a clear, customer-friendly description so customers understand why their points balance changed, such as **Bonus points for your order.**
