# Fulfillment: Track Order Fulfillment Events

> Track fulfillment events for your Shopify store. Monitor when orders are shipped and fulfilled to understand delivery performance.

<Tip>
  Fulfillment counts the number of orders that have been fulfilled (shipped) in your Shopify store.
</Tip>

## Formula

<Info>
  **Fulfillment** = **COUNT** ( Fulfillment Events )
</Info>

### Formula Components

| Metric                 | Definition                                        |
| ---------------------- | ------------------------------------------------- |
| **Fulfillment Events** | Individual order fulfillment records from Shopify |

| Metadata        |                                                              |
| --------------- | ------------------------------------------------------------ |
| **Type**        | Count                                                        |
| **Data Source** | [Upstack Pixel](/pixel), [Shopify](/sources/catalog/shopify) |
| **Aggregation** | Count                                                        |

## Example

Your Shopify store received **1,247 orders** in January, and **1,189 fulfillments** were recorded during the same period.

| Period        | Orders    | Fulfillments | Fulfillment Rate |
| ------------- | --------- | ------------ | ---------------- |
| January 1–15  | 623       | 598          | 96.0%            |
| January 16–31 | 624       | 591          | 94.7%            |
| **Total**     | **1,247** | **1,189**    | **95.3%**        |

***

## How It Works

Fulfillment events are captured when Shopify marks an order as fulfilled. This typically occurs when a shipping label is created or when the order is handed off to a carrier. Upstack syncs these fulfillment events in real-time from your Shopify store.

| ----------------------------- | -------------------------------------------------- |
| Tracking shipping performance | Monitor fulfillments vs orders to identify backlog |
| Analyzing fulfillment speed   | Compare fulfillment counts across time periods     |
| Auditing warehouse operations | Spot days with low fulfillment counts              |
