SaaS & APIs
Charge monthly for your app or your API. We run the billing; your code reads our status endpoint and unlocks the features. You never store a card.

Charge every month. Build none of the billing.
You are building something people pay for again and again. The hard part should be the product, not the billing: webhooks, retries, dunning, a customer portal, a ledger of who is still active. Connect the provider account you already have, wire one button, and start charging. The renewals run on their side, the money lands in your account and never ours, and you never built the plumbing.

Charge monthly.They stay.It compounds.
A subscribe button on the pricing page you already have. Your buyer never gets handed off to someone else’s checkout, the card lives with your provider, and the revenue lands in your account, not ours.
Three steps. No backend.
- 1Connect the provider account you already have, your Stripe or PayPal. The money lands there, never with us.
- 2Create a plan, then paste one subscribe button on your pricing page.
- 3They subscribe. Your provider runs every renewal; your dashboard shows which subscriptions are active.
We run the billing. You run the product.
We are the billing layer, not your app, and not your merchant of record. You connect your own provider account; it charges the cards and holds the funds. We track which subscriptions are active and hand you that signal through one status endpoint. Gating the actual thing stays in your code: the login, the members area, the locked feature. That line is on purpose: your subscribers live with your provider, never in our database, so you stay the only one who holds your customer list.
Want a members-only area with no backend at all? That is a membership tool’s job. Pair us underneath as the payment layer.
Recurring, however you charge
One subscribe button covers every shape of monthly revenue.
Memberships & communities
A paid Discord, a private feed, a members-only newsletter. Monthly or yearly on the same button. You let people in; we keep the billing honest.
Retainers & services
Coaching, audits, a done-for-you service on a monthly retainer. The invoice recurs on its own, so you stop chasing and keep delivering.
Annual plans & trials
Offer a yearly price or a free trial up front. Your provider holds the card and runs the schedule; you set the terms and keep the upside.
The risk is the idea, not the infrastructure.
Startups die from building the wrong thing slowly. Do not burn week one on webhooks, retries, and a dunning flow. Billing is solved the moment you paste the button, so the only bet left is whether people want what you made. If they do not, you point the open SDK somewhere else and walk. No platform owns your customers, because we never did.
