Stripe subscription billing, owned end to end

What I'd bring to your team

  • The full subscription lifecycle

    Sign-up through Checkout, upgrades, cancellations and receipts, all reflected in your own database.

  • Usage-based metering

    Recording usage and reporting it to Stripe, as I do for Emergi Mentors' metered plans.

  • Tiered plans

    Plans that scale from one user to a business, like Wheelyst's Starter, Pro and Fleet tiers.

  • Webhook handling

    Stripe events processed on the backend so subscription state stays correct without manual fixes.
