# Customers

How customer data flows depends on which booking method is used.

## Shopify Checkout

When a customer books through Shopify checkout, a Shopify order and customer record are created automatically. This gives you full access to Shopify's customer management tools.

## Sesami Instant Booking

With [Sesami Instant Booking](/booking/booking-features/instant-booking.md), customers skip Shopify checkout entirely — so no Shopify customer record is created automatically.

To capture and manage customer data with Sesami Instant Booking, use the [Klaviyo integration](/apps-integrations/klaviyo.md) to track booking events and build customer profiles.

## Auto-Tag Customers with Shopify Flow

For customers who go through Shopify checkout, you can automatically tag them using Shopify Flow. This is useful for:

* **Segmentation** — identify customers who've booked vs. those who haven't
* **Marketing** — create targeted campaigns in Klaviyo or other tools
* **Reporting** — filter and track booking customers in Shopify

### How to Set It Up

1. Go to **Shopify > Apps > Shopify Flow**
2. Create a new workflow
3. Set the **trigger** to "Order created"
4. Add a **condition** to check if the order contains a Sesami booking product (e.g., check for a specific product tag or the "Duration" line item property)
5. Add an **action** to tag the customer (e.g., "booked-appointment")
6. **Save and activate** the workflow

{% hint style="info" %}
Once customers are tagged, you can use these tags in Klaviyo, Shopify Email, or other marketing tools to create targeted segments.
{% endhint %}
