Hey there! I’ve worked on similar Drupal 7 Commerce setups before, so let’s walk through the most reliable approach to build your subscription-to-points system.

Core Module Stack (Drupal 7 Compatible) #

First, you’ll need these tried-and-tested modules to avoid reinventing the wheel:

• Commerce Recurring: Handles monthly subscription billing, automatic renewals, and subscription management (critical for recurring payments).
• User Points: Manages all aspects of user points—tracking balances, awarding, deducting, and logging activity.
• Commerce User Points: Bridges User Points with Drupal Commerce, letting users redeem points as payment for products.
• Rules: The glue that ties everything together (triggering point awards on successful payments, handling subscription cancellations, etc.).

Step-by-Step Implementation #

1. Set Up Base Modules
   Install and enable all the modules above, making sure you pick versions explicitly compatible with Drupal 7 and your existing Commerce setup. Run database updates as needed.

2. Create a Subscription Product

   • In Drupal Commerce, create a new product type (e.g., "Monthly Subscription") if you don’t have one.
   • Add a product of this type, set its price (your monthly fee), and use Commerce Recurring to configure the recurring cycle: set it to "Monthly" and define renewal behavior (auto-renew by default, with an option for users to cancel).

3. Automate Point Awards with Rules

   • Create a new Rule with the event "Commerce recurring payment completed" (triggers every time a user’s monthly subscription payment goes through).
   • Add an action "Add points to a user": select the current user, set the number of points to award (e.g., 100 points for a $10/month subscription), and add a descriptive message like "Points awarded for monthly subscription renewal".
   • Optional: Add a second rule for the initial subscription purchase (event: "Commerce order has been paid in full") to award points for the first payment.

4. Configure Point Redemption

   • In the Commerce User Points settings, set the exchange rate between points and your site’s currency (e.g., 1 point = $0.01, or 100 points = $1).
   • Enable the "Allow users to redeem points during checkout" option, so users see a checkbox/input to use their points when paying for products.
   • Optional: Restrict redemption to specific product categories or products using Rules (e.g., only allow points for physical goods, not digital downloads).

5. Add Subscription & Point Management UI

   • Use Views to create a user-facing dashboard showing their current subscription status, next renewal date, point balance, and point transaction history.
   • Add links for users to cancel their subscription (handled by Commerce Recurring) directly from their account page.

Key Customizations & Best Practices #

• Point Expiration: If you want points to expire (e.g., 90 days after being awarded), create a Rule with a scheduled event: "User points have expired" (using User Points’ built-in expiration features) to automatically deduct expired points and notify the user.
• Subscription Cancellation Handling: Create a Rule triggered by "Commerce recurring subscription has been canceled" to stop future point awards and send a confirmation email to the user.
• Transparency: Enable User Points’ logging feature so users can see exactly when points were added or deducted—this builds trust.
• Testing: Test every flow end-to-end: subscribe, pay, receive points, redeem points for a product, cancel subscription, and verify point expiration. Use Drupal’s test payment gateway to avoid real charges during testing.
• UI Polish: Add a prominent point balance display in the site header or user account menu, and add labels on product pages like "Use your subscription points to pay for this item!" to encourage redemption.

Final Notes #

Since Drupal 7 is end-of-life, make sure your site is running the latest security patches for all modules. If you plan to migrate to Drupal 10 later, keep this implementation as modular as possible—most of these concepts translate to Drupal 10 Commerce (using Commerce Subscriptions and a points module like Commerce Points).
