System for organizing, tracking, and enforcing subscription tiers and usage limits


Core Idea:

User plan management is the systematic approach to defining, implementing, and enforcing different service tiers with varying features, usage limits, and pricing to maximize customer value and business revenue.


Key Principles:

  1. Tiered Access Control:
    • Features and capabilities are enabled or disabled based on subscription tier.
  2. Usage Tracking:
    • Monitoring and measuring resource consumption to enforce limits and calculate billing.
  3. Entitlement Management:
    • Rules-based system for determining what features and resources users can access.

Why It Matters:


How to Implement:

  1. Define Plan Structure:
    • Create distinct subscription tiers with clear feature differentiation and pricing.
  2. Implement Usage Tracking:
    • Build systems to monitor, measure, and record consumption of key resources.
  3. Enforce Access Controls:
    • Apply permission checks in application code to limit feature access based on subscription status.

Example:

// User plan definitions
const PLANS = {
FREE: {
name: 'Free',
price: 0,
monthlyConversions: 3,
maxFileSize: 5, // MB
features: {
basicOcr: true,
advancedOcr: false,
batchProcessing: false,
apiAccess: false
}
},
PRO: {
name: 'Pro',
price: 10,
monthlyConversions: 50,
maxFileSize: 10, // MB
features: {
basicOcr: true,
advancedOcr: true,
batchProcessing: false,
apiAccess: false
}
},
PRO_PLUS: {
name: 'Pro Plus',
price: 50,
monthlyConversions: 100,
maxFileSize: 25, // MB
features: {
basicOcr: true,
advancedOcr: true,
batchProcessing: true,
apiAccess: true
}
}
};

// Check user authorization for feature access
function canUseFeature(user, feature) {
const userPlan = PLANS[user.subscription.plan];
return userPlan && userPlan.features[feature];
}

// Check if user has remaining conversions
async function hasRemainingConversions(userId) {
// Get user's subscription details
const user = await getUserData(userId);
const planLimits = PLANS[user.subscription.plan];

// Count usage in current billing period
const currentUsage = await countUserConversions(userId, user.subscription.currentPeriodStart);

return currentUsage < planLimits.monthlyConversions;
}

// Track usage when processing an image
async function processImage(userId, imageFile) {
// Check plan constraints
if (!await hasRemainingConversions(userId)) {
throw new Error('Monthly conversion limit reached');
}

const user = await getUserData(userId);
const planLimits = PLANS[user.subscription.plan];

if (imageFile.size > planLimits.maxFileSize * 1024 * 1024) {
throw new Error('File exceeds maximum size for your plan');
}

// Process image if constraints are satisfied
const result = await performOcr(imageFile, user);

// Record usage
await recordConversion(userId);

return result;
}
```
