A Plan is the core billing product in Fluxrate. It packages together:
  • Features — what capabilities the plan unlocks
  • Charges — how much and how the customer is billed
Customers subscribe to plans, and Fluxrate automatically manages the billing cycle.

​
Plan Types

Fixed

Flat recurring fee. Simple and predictable. Great for SaaS subscriptions.

Usage-based

Charge based on consumption. Pay-as-you-go. Great for APIs and infrastructure.

Hybrid

Base fee + usage charges. Best of both worlds for modern SaaS.

Plan Lifecycle

Active → Deactivated (no new subscriptions)
A plan cannot be deleted if it has active subscriptions. You must first cancel or migrate all subscriptions before deleting.
Once a plan has active subscriptions, changes to pricing may affect existing customers. Consider creating a new plan version instead.

Plan Structure Example

Here’s how a complete “Pro” plan might look: 
Pro Plan ($49/month + usage)
├── Features
│   ├── API Calls (meter) → 50,000 calls/month limit
│   ├── Analytics Dashboard (switch) → enabled
│   └── Max Team Members (custom) → "10"
└── Charges
    ├── Base Fee → $49/month (FIXED)
    └── API Call Charge → $0.001/call (USAGE, linked to api_calls meter)
