Subscription Billing Is More Complex Than It Looks

A simple recurring charge is easy — charge a card every month. Production subscription billing is not: plan upgrades mid-cycle with prorated amounts, annual plan discounts, trial periods that convert at the right time, dunning sequences for failed payments, revenue recognition compliance, metered billing for API usage, and tax collection across jurisdictions. Getting any of these wrong costs revenue or creates compliance exposure.

In 2026, four platforms define the developer-facing subscription management market: Stripe Billing (API-first, built into the Stripe ecosystem), Chargebee (revenue lifecycle management for SaaS), Recurly (mid-market subscription billing with strong dunning), and Lago (open-source, self-hostable metered billing).

TL;DR

Stripe Billing is the default for Stripe-native applications — the API is excellent, the integration with Stripe Checkout/Stripe Tax/Stripe Connect is seamless, and the 0.7% fee is reasonable. Chargebee is the right choice for SaaS teams that want subscription billing + revenue recognition + churn analytics in one platform, and the free-until-$250K tier is genuinely generous for early-stage. Recurly is purpose-built for dunning and retention — if failed payment recovery matters, Recurly's dunning workflows are the best in the market. Lago is the open-source alternative for teams building usage-based billing and wanting to self-host at zero licensing cost.

Key Takeaways

  • Stripe Billing charges 0.7% per transaction on top of standard Stripe processing fees (2.9% + 30¢) — at $100K MRR, that's $700/month in billing fees alone.
  • Chargebee is free until $250K lifetime billing — genuinely free for early-stage SaaS, then 0.75% overage on revenue above the threshold.
  • Recurly starts at $249/month for up to $40K/month in billing — expensive for small teams but strong for $50K+ MRR.
  • Lago is MIT-licensed and self-hostable — zero licensing cost, full metered billing features, suitable for teams with engineering resources.
  • Dunning (failed payment recovery) varies dramatically — Recurly's intelligent dunning recovers a reported 10-15% more revenue than simple retry logic.
  • Revenue recognition (ASC 606) is a feature in Chargebee and Recurly — critical for companies approaching audit or fundraising.
  • All four support usage-based billing — but Lago and Stripe Billing are the most developer-native for API-based consumption pricing.

Stripe Billing

Best for: Stripe-native teams, API-first billing, teams already using Stripe for payments

Stripe Billing extends Stripe's payment infrastructure with subscription management, invoicing, proration, trials, and metered billing. If you're already using Stripe, adding Billing is the lowest-friction path — you don't add a new vendor, you extend an existing one.

Pricing

  • Fee: +0.7% on every transaction billed through Stripe Billing
  • No monthly minimum
  • Includes: Invoicing, subscription management, proration, trials, smart retry

Subscription API

import stripe

stripe.api_key = "sk_live_..."

# Create a subscription with trial
subscription = stripe.Subscription.create(
    customer=customer_id,
    items=[{"price": "price_pro_monthly"}],
    trial_period_days=14,
    payment_behavior="default_incomplete",
    payment_settings={"save_default_payment_method": "on_subscription"},
    expand=["latest_invoice.payment_intent"],
)

# Handle proration on plan change
subscription = stripe.Subscription.modify(
    subscription_id,
    items=[{"id": item_id, "price": "price_enterprise_monthly"}],
    proration_behavior="create_prorations",
)

Metered Billing (Usage-Based)

# Report usage for metered billing
usage_record = stripe.SubscriptionItem.create_usage_record(
    subscription_item_id,
    quantity=1500,  # API calls this billing period
    timestamp="now",
    action="set",  # or "increment"
)

# Customer is billed based on reported usage at period end

When to Choose Stripe Billing

Teams already using Stripe as their payment processor, applications needing tight integration with Stripe Checkout, Stripe Connect, or Stripe Tax, or teams that want a single vendor for all payment infrastructure.

Chargebee

Best for: SaaS revenue lifecycle management, free tier for early-stage, revenue recognition

Chargebee is more than a billing API — it's a revenue operations platform covering the entire subscription lifecycle: billing, invoicing, revenue recognition, churn analytics, self-service portals, and integrations with Salesforce, HubSpot, and NetSuite. It's the right choice when you need non-technical teams (finance, ops, CS) to manage subscriptions alongside engineering.

Pricing

PlanCostRevenue LimitFeatures
Free (Starter)$0$250K lifetimeCore billing
Growth0.75% overageAfter $250KAdvanced features
ScaleCustomUnlimitedRevenue recognition, teams

The $250K lifetime free tier is genuine — many SaaS companies operate within this before paying anything.

Subscription API

import chargebee

chargebee.configure("api_key", "site-name")

# Create a subscription
result = chargebee.Subscription.create_with_items(
    customer_id="customer_123",
    subscription_items=[{
        "item_price_id": "pro-monthly-USD",
        "quantity": 1,
        "unit_price": 9900,  # in cents
    }],
    metadata={"userId": "user_123"},
)

subscription = result.subscription

# Schedule a plan change (at next renewal)
result = chargebee.Subscription.update(
    subscription.id,
    plan_id="enterprise-monthly-USD",
    end_of_term=True,  # Change takes effect at period end
)

Revenue Recognition

Chargebee's RevRec module handles ASC 606 compliance — automatically recognizing subscription revenue over the service period rather than at invoice date:

  • Deferred revenue tracking
  • Multi-element arrangement support
  • Audit-ready reporting
  • NetSuite / QuickBooks integration

This becomes critical when raising a Series A or preparing for financial audit.

Self-Service Portal

// Redirect to Chargebee's hosted self-service portal
const portal = await chargebee.PortalSession.create({
  customer: { id: customerId },
});

// Customer can manage payment methods, view invoices, upgrade/downgrade
window.location.href = portal.access_url;

When to Choose Chargebee

Early-stage SaaS (free until $250K lifetime billing), teams that need non-technical subscription management (the Chargebee dashboard is the best for ops/finance teams), businesses approaching audit that need revenue recognition, or companies with complex plan structures (tiered pricing, add-ons, usage-based components).

Recurly

Best for: Mid-market SaaS, best-in-class dunning, subscription analytics, churn reduction

Recurly's core differentiator is intelligent dunning — their revenue recovery system automatically retries failed payments with optimized timing, sends customized email sequences, and reports recover a reported 10-15% more revenue than basic retry logic. For subscription businesses where payment failure is a significant revenue leak, Recurly pays for itself.

Pricing

PlanCostBilling CapOverage
Core$249/month$40K/month0.9%
Professional$449/month$100K/month0.9%
Elite$1,249/month$300K/month0.75%

Dunning System

Recurly's intelligent retry uses:

  • Machine learning to optimize retry timing per customer
  • Customizable email sequences (7-day, 14-day, 30-day dunning flows)
  • Account Updater to automatically refresh expired cards (Visa/Mastercard)
  • Automatic account pause before cancellation
import recurly

recurly.API_KEY = "your-api-key"

# Configure dunning campaign via API
campaign = recurly.DunningCampaign.get("default")

# Custom dunning profile per subscription tier
subscription = recurly.Subscription.get(subscription_id)
subscription.dunning_campaign_id = "high-value-campaign"
subscription.save()

When to Choose Recurly

$50K+ MRR businesses where dunning ROI justifies the base cost, companies with high payment failure rates (especially B2C subscriptions), mid-market SaaS with complex subscription lifecycles, or teams that need subscription analytics alongside billing.

Lago

Best for: Open-source, self-hosted, usage-based billing, developer-native

Lago is the open-source billing platform — MIT licensed, fully self-hostable, and purpose-built for usage-based billing (metered, per-event, per-seat pricing). For engineering teams that want full control over billing infrastructure without licensing fees, Lago is the only enterprise-capable open-source option.

Pricing

  • Self-hosted: Free (MIT license, run on your infrastructure)
  • Lago Cloud: Managed hosting at commercial rates

Usage-Based Billing API

# Ruby SDK
require 'lago-ruby-client'

client = Lago::Api::Client.new(api_key: 'your-api-key')

# Record a billable event
client.events.create({
  transaction_id: SecureRandom.uuid,
  external_customer_id: 'customer_123',
  code: 'api_calls',       # Billable metric
  timestamp: Time.now.to_i,
  properties: {
    endpoint: '/api/data',
    response_time_ms: 145,
  },
})

# Define a billable metric in Lago
billable_metric:
  name: "API Calls"
  code: "api_calls"
  aggregation_type: "count_agg"   # Count all events
  # Or "sum_agg" to sum a property value
  # Or "unique_count_agg" for unique values

Verdict

Stripe Billing is the natural choice for Stripe-native applications. The 0.7% fee is straightforward, the API is excellent, and the integration with the broader Stripe platform (Tax, Connect, Radar) is unmatched.

Chargebee is the smart choice for early-stage SaaS — genuinely free until $250K in lifetime billing, and the revenue lifecycle management features (revenue recognition, churn analytics, CS team tooling) grow with you.

Recurly is justified when payment failure recovery is a significant revenue problem. The dunning system's reported 10-15% revenue recovery improvement pays for the $249/month base cost at scale.

Lago is the answer for engineering teams that want open-source billing infrastructure without licensing fees — the right call when billing is a core competency you want to own.
