Beyond Monthly: Custom Billing

Not all businesses fit a simple monthly or yearly billing plan. Imagine you need to bill clients quarterly, bi-weekly, or on a specific day of the month.

Stripe's flexible API allows you to define highly customized billing cycles and schedules to match unique business requirements and customer agreements.

Defining Custom Intervals

Stripe uses two key properties to define billing intervals for a Price object:

  • interval: The unit of time (e.g., day, week, month, year).
  • interval_count: How many of the interval units.

For example, interval: 'month', interval_count: 3 means 'every three months' (quarterly).

Price with Custom Interval

Here's how you might create a new Price in Stripe that bills every two weeks. Notice the interval and interval_count.

// This is a simplified example.
// In a real application, you'd require and
// initialize the Stripe library.
// const stripe = require('stripe')('sk_test_YOUR_KEY');

async function createCustomPrice() {
  console.log("Simulating Stripe API call to create a Price.");

  const priceData = {
    unit_amount: 1500, // $15.00
    currency: 'usd',
    recurring: {
      interval: 'week',
      interval_count: 2 // Bill every two weeks
    },
    product_data: {
      name: 'Bi-Weekly Service Plan',
    },
    nickname: 'Bi-Weekly Service Plan - $15',
  };

  console.log("Attempting to create Price with:", priceData);
  // await stripe.prices.create(priceData);
  console.log("Price creation simulated successfully.");
}

createCustomPrice();

Introducing Billing Cycle Anchor

Beyond just the interval, sometimes you need to control when the billing cycle starts. This is where the billing_cycle_anchor comes in.

  • It's a Unix timestamp representing the exact date and time when the subscription's billing cycle should begin.
  • It's crucial for aligning billing dates across multiple customers or specific business requirements.

Subscription with Future Anchor

Let's say a customer signs up today but wants their first bill to always be on the 1st of the next month. You can set a billing_cycle_anchor when creating the subscription.

Stripe will automatically prorate (if applicable) or delay the first invoice until this date.

// This is a simplified example.
// const stripe = require('stripe')('sk_test_YOUR_KEY');

async function createSubscriptionWithAnchor() {
  console.log("Simulating Stripe API call to create Subscription.");

  const now = new Date();
  const nextMonth = new Date(now.getFullYear(), now.getMonth() + 1, 1); // 1st of next month
  const anchorTimestamp = Math.floor(nextMonth.getTime() / 1000); // Unix timestamp

  const subscriptionData = {
    customer: 'cus_xyz123', // Replace with a real customer ID
    items: [{ price: 'price_abc456' }], // Replace with your price ID
    billing_cycle_anchor: anchorTimestamp,
    // You might also add trial_end here if applicable
  };

  console.log("Attempting to create Subscription with anchor:", subscriptionData);
  // await stripe.subscriptions.create(subscriptionData);
  console.log("Subscription creation simulated successfully.");
}

createSubscriptionWithAnchor();

Aligning Billing Dates

A common use case for billing_cycle_anchor is to ensure all your customers are billed on a specific day of the month (e.g., the 1st or the 15th), regardless of their signup date.

This simplifies financial reconciliation and provides a predictable billing schedule for your operations.

Anchor & Trial Periods

billing_cycle_anchor works well with trial periods. You can set a trial to end, and then have the first billing cycle after the trial begin on a specific anchor date.

This provides a smooth transition from trial to paid, aligned with your custom billing schedule.

Proration with Anchors

When you set or change a billing_cycle_anchor for an existing subscription, Stripe often calculates a proration.

  • Proration is a partial charge or credit for the period between the change and the new billing cycle start.
  • Stripe handles this automatically, but it's important to be aware of how it impacts customer invoices.

Modifying Subscription Anchor

You can also update an existing subscription's billing_cycle_anchor. This is useful if a customer requests a change to their billing date or if you need to realign schedules.

Remember to handle potential prorations if you're moving the date mid-cycle.

// This is a simplified example.
// const stripe = require('stripe')('sk_test_YOUR_KEY');

async function updateSubscriptionAnchor() {
  console.log("Simulating Stripe API call to update Subscription.");

  const subscriptionId = 'sub_def789'; // Replace with a real subscription ID
  const newAnchorDate = new Date();
  newAnchorDate.setDate(newAnchorDate.getDate() + 30); // Anchor 30 days from now
  const newAnchorTimestamp = Math.floor(newAnchorDate.getTime() / 1000);

  const updateData = {
    billing_cycle_anchor: newAnchorTimestamp,
    proration_behavior: 'always_invoice', // Or 'create_prorations'
  };

  console.log(`Attempting to update Subscription ${subscriptionId} with anchor:`, updateData);
  // await stripe.subscriptions.update(subscriptionId, updateData);
  console.log("Subscription update simulated successfully.");
}

updateSubscriptionAnchor();

Custom Cycle Check

You want to create a new Stripe Price that bills customers every three months. Which combination of parameters should you use?

Recap: Custom Billing Cycles

In this lesson, we explored how to create highly customized billing cycles and schedules using Stripe:

  • We learned to define custom intervals for Price objects using interval and interval_count.
  • We understood the role of billing_cycle_anchor for fixing specific billing dates.
  • We saw how to set future anchors for new subscriptions and update them for existing ones, while considering prorations.

This flexibility allows you to tailor your billing to diverse business needs.
