Order Finalization Process at Mr D: A Comprehensive Guide 📦

This document provides a detailed overview of how Mr D finalizes grocery orders, demonstrating the intricacies involved from receiving packed order details to completing the customer experience.

1. Introduction to the Order Finalization Process 🔍

The finalization of grocery orders at Mr D is a critical step that ensures customers receive their purchases accurately and efficiently. This process begins once the order packing is complete and continues through to the customer receiving their items. Understanding the business logic underpinning this process is essential for developers and testers tasked with implementing and verifying the order finalization workflow.

2. Structure of Final Order JSON Packet 📊

Upon completion of the packing process, a JSON packet comprising the order details is generated and transmitted. This packet includes vital information such as:

• Variable Weight Products: These items require dynamic calculation of their price based on weight.
• Bag Details: Information regarding the number of bags used for packing and their respective barcodes.

A sample JSON structure might resemble the following:

{
  "orderId": "12345",
  "packedItems": [
    {
      "productId": "abc",
      "packedQuantity": 3,
      "packedPrice": 15.00,
      "barcode": "XYZ123"
    }
  ],
  "numberOfBags": 2,
  "subtotal": 30.00
}

This structure allows for consistency in processing while accommodating various product types and quantities.

3. Finalizing the Order: Key Actions to Execute 🔑

Once the JSON packet is received, Mr D must conduct a series of actions to finalize the order:

1. Saving Final Order Totals: Capture the overall total, confirming it reflects the packed items.
2. Saving Picked Items and Out-of-Stock Items: Documentation of what was successfully packed versus what was unavailable.
3. Logging Bag Information: Store the number of bags used along with their respective barcodes.
4. Calculating Wallet Credits: This is pivotal for enabling customer loyalty incentives, ensuring accurate wallet adjustments are made following the order total.
5. Injecting the Order to TDT: Once savings are executed, the order is injected into the TDT system for further processing.
6. Crediting the Customer Wallet: The calculated wallet credit must be issued, categorized as an “Alternative Credit.”
7. Final Customer Notification: An email confirmation must be sent to inform the customer of the successful order handling and wallet credit application.

These steps, when executed properly, ensure accuracy and enhance the customer experience.

4. Wallet Credit Management and Customer Interaction 💰

Following order finalization, it is essential to manage customer wallet credits effectively:

• Single Credit Wallet: Each customer maintains a single credit wallet, where all credits from grocery and food orders accumulate.
• Automatic Application of Credits: Available wallet credit is automatically deducted from the total during subsequent purchases, streamlining the checkout process for returning customers.
• Wallet Payout Requests: Customers have the ability to request payouts for their total wallet credit, fostering financial transparency and engagement.

The system aims to enhance customer loyalty by creating a seamless experience that utilizes earned credits efficiently.

5. Validation Criteria for Packed Orders ✔️

To ensure that the order finalization is consistent with customer expectations, several validation checks must be implemented:

• Packed Price vs. Placed Price: Ensure that the final packed price isn't less than the originally placed price to maintain transparency.
• Quantity Validation: Packed quantities must meet or exceed those placed in the order.
• Subtotal Comparison: The packed subtotal should not exceed the subtotal initially agreed upon, safeguarding customer trust.

These validation criteria not only reinforce order accuracy but also enhance the reliability of the overall service.
