Annual subscriptions are one of the highest-impact features you can add to a SaaS business. They improve cash flow (12 months upfront vs monthly payments), dramatically reduce churn (an annual subscriber churns at 1/4 the rate of a monthly subscriber), and signal customer commitment. Here's how to implement them correctly in Stripe.
Stripe Setup for Annual Plans
For each subscription tier, create two Prices in Stripe — one monthly and one annual:
- Pro Monthly: $99/month, billed monthly
- Pro Annual: $79/month, billed annually ($948/year) — equivalent to 20% off
Both Prices belong to the same Product. The discount is implicit in the annual Price — not applied via a Stripe coupon.
Monthly/Annual Toggle
Your pricing page should have a toggle between monthly and annual billing. When toggled, the prices display the monthly equivalent with "billed annually" note and highlight the savings. This is purely a frontend UI — the actual Price ID used in checkout changes based on the toggle state.
Switching Between Monthly and Annual
When a monthly subscriber switches to annual (an upgrade), Stripe handles proration: they receive credit for unused days on their monthly plan and are charged the prorated annual amount. Configure this in Stripe: proration_behavior: 'create_prorations'.
When switching from annual to monthly (a downgrade), apply the change at the end of the current billing period to avoid complexity.
Annual Renewal Reminders
Annual subscribers should receive renewal reminders 30 days before their anniversary. Stripe sends the invoice.upcoming webhook 7 days before renewal — but for annual plans, you want more notice. Implement a daily cron job that queries Stripe for subscriptions renewing in 30 days and sends renewal reminder emails.

Start on Fiverr →Incentivizing Annual Upgrades
Periodically offer monthly subscribers an upgrade to annual with an extra incentive: "Switch to annual and get 2 months free" or "Annual Black Friday sale — save 30%." Send this offer to monthly subscribers who have been active for 3+ months — they've validated the product and are most likely to commit.
