# Include Preparation Time - Estimated Delivery Date ‑ ETA

The **Include Preparation Time** feature lets you add processing time to orders before shipping begins. This ensures that the estimated delivery date (ETA) reflects both preparation and delivery durations, providing a more accurate timeline to customers.

**This guideline helps you understand, configure, and use the Include Preparation Time feature effectively to improve delivery accuracy and customer communication.**

### How It Works
When enabled, preparation time is automatically added to the ETA calculation before delivery time.

**ETA Calculation:**
Order Date → Preparation Time → Delivery Time(Estimated Delivery Date)


### Configuration Steps: 


1. **Toggle the switch On**:  Go to Application Settings → Find Include Preparation Time → Enable → Enter Preparation Days

**After Enabling**: Preparation time is added before delivery time ETA updates automatically based on configured days

### Example
* **Order Date:** March 19

* **Delivery Time:** 2 days
**Estimated Delivery Date:** March 25

| Note : Preparation time applies before delivery, changes affect new orders only, and preparation days should match actual processing time

### Best Practices
* Regularly review and update preparation time based on order volume
* Clearly communicate delivery timelines on product pages
* Test ETA calculations after enabling the feature to ensure accuracy

### Benefits
* Improves delivery accuracy
* Sets clear customer expectations
* Reduces support queries related to delivery timelines

### Summary
Enabling **Include Preparation Time** ensures that order processing time is included in delivery estimates, resulting in more accurate ETAs and a better customer experience.
