Understanding these core concepts will make it easier to design your pricing and integrate the SDK.

​
Products

A product is the main thing you sell. Examples: “Cursor”, “TimeMaster Pro”, or “API Service”. Learn more about products →

​
Features

A feature is a capability a customer can access. Features are defined once and can be reused across plans. Examples: API access, AI tokens, storage space, priority support. Learn more about features →

​
Plans

A plan is how you package and price your product. You attach features and prices to a plan. Examples: Free, Starter, Pro, Enterprise. Learn more about plans →

​
Entitlements

Entitlements define how a customer can use a feature within a plan. Examples:
  • 1,000 API calls per month
  • 10,000 AI tokens per month
  • 100 GB storage space
Entitlements can be boolean (on/off), metered (usage limits), or config (custom values). Learn more about entitlements →

​
Digital downloads

A digital download is a file that your customers can download after purchasing. Examples: e-books, software, music, videos. Learn more about digital downloads →

​
License keys

A license key is a code that your customers can use to activate a digital download. Examples: software activation, game keys, e-books. Learn more about license keys →
Links allow you to share important URLs with customers after they purchase your plan. Examples: Discord servers, Slack workspaces, Notion pages, member-only dashboards. Learn more about links →

​
Customers

A customer is a person or company that purchases your product. Typically, you create a customer record when someone signs up in your app. When they complete a purchase, Kelviq maps the transaction to the customer record automatically. Learn more about customers →

​
Typical workflows

​
One-time products

Selling digital downloads, license keys, or access links:
  1. Create a product
  2. Create a plan with one-time pricing
  3. Add digital downloads, license keys, or links to the plan
  4. Share your checkout link or embed a pricing table
  5. Customer purchases → receives their files, keys, and links

​
SaaS subscriptions

Selling recurring access with feature limits:
  1. Create features (e.g., API calls, storage, AI tokens)
  2. Create a product
  3. Create plans with recurring pricing (monthly/yearly)
  4. Add entitlements to each plan (e.g., 1,000 API calls/month)
  5. Integrate the SDK to check feature access and enforce limits
  6. Customer subscribes → SDK controls what they can access

​
Integrate with your app

To bring everything you set up in the dashboard into your app, use one of these options:
  • SDKs — check feature access and enforce usage limits in code
  • APIs — use for custom needs such as syncing usage or triggering upgrades
No webhooks required. Kelviq SDKs and UI widgets stay in sync automatically—no need to build webhook handlers or manage event processing.
