Pricing Calculation

The Pro plan uses the following pricing structure from planPrice.js:1:
  • Base Price: ₹799.00/month (79900 paise)
  • Discounts by Duration:
    • 1 month: 0% discount → ₹799
    • 3 months: 4% discount → ₹2,300.64
    • 6 months: 8% discount → ₹4,417.92
    • 12 months: 10% discount → ₹8,629.20
    • 24 months: 15% discount → ₹16,297.20

​
Calculation Formula

finalAmount = months × basePrice × (1 - discount / 100)

​
Database Records

On successful Razorpay order creation, a PendingOrder record is created:
  • userid: Authenticated user ID
  • oderid: Razorpay order ID
  • months: Subscription duration
  • amount: Final calculated amount
  • plan: Always "pro" for paid plans
  • status: "pending"

Pending orders automatically expire after 2 hours if payment is not completed.

​
Implementation Details

The endpoint is implemented in init.controller.js:11 and:
  1. Validates the plan parameter
  2. For free plans, creates a project immediately with no payment
  3. For paid plans:
    • Validates the months parameter
    • Retrieves pricing from planPrice.js
    • Calculates discount based on duration
    • Creates Razorpay order
    • Stores pending order in database
  4. Returns the appropriate response
The final amount is converted to an integer using parseInt(), which may cause precision issues. Ensure the calculation months * basePrice * (1 - discount / 100) results in a whole number.

​
Next Steps

After receiving the Razorpay order details:
  1. Use the Razorpay Checkout SDK on your frontend to collect payment
  2. On successful payment, Razorpay will provide:
    • razorpay_payment_id
    • razorpay_order_id
    • razorpay_signature
  3. Send these to the Verify Payment endpoint to activate the subscription
