Certus is one system for checkout, payment routing and recovery messaging. It sits inside the transaction, so every tool downstream knows what actually happened to the money.
1.25% + 29¢ per successful transaction. No decline fees. Settles to your own bank account.
Works with 50+ gateways and platforms, including
Most stacks handle each one in a different tool. Certus runs them as one sequence.
Acquire
Server-side tracking hands every ad platform a clean conversion signal.
Convert
A checkout that adapts to device, country and wallet before the first keystroke.
Upsell
One-click offers after payment, priced and tested per segment.
Recover
Abandonment and dunning flows triggered by what the processor saw, not the browser.
Renew
Subscriptions with smart retries, cascades and replenishment nudges.
Each tool in a fragmented stack sees one slice of the customer and acts on it alone. The revenue leaks in the gaps between them.
Flows is the visual builder for the whole journey. Drag a checkout, a routing rule, a retry and an SMS onto the same canvas and ship it. Every node runs on real payment events.
Adaptive storefront pages, intelligent checkout, dynamic upsells and cross-sells, native server-side tracking. One conversion surface across every store page.
Route every transaction across Certus Processing and 40+ gateways with rules you set. Cascade declines to a second route automatically and settle to your own accounts.
Email and SMS keyed to payment events: approvals, declines, refunds and renewals. Recovery, abandonment and replenishment sequences without a second tool.
If you are moving off CheckoutChamp, Funnelish, sticky.io or ClickFunnels, the migration is a routing rule and a redirect.
Certus started as the internal billing layer of a subscription brand that couldn't get its approval rate above 80%. The fix wasn't a better processor. It was a system that knew, at the moment of the decline, which customer this was, what they had bought before, and which route to try next.
Every other tool in the stack was integrating with the transaction from the outside. We built one that lives inside it, then opened it up.
TypeScript-first SDK with zero dependencies for React, Vue, Svelte or plain HTML. Webhooks for every payment event. An MCP server so Claude, Lovable or v0 can build your storefront against live products.
import { Certus } from "@certus/sdk";
const certus = new Certus({ store: "acme-labs" });
const session = await certus.checkout.create({
product: "prod_starter_kit",
upsells: ["prod_refill_pack"],
route: "auto", // cascade on decline
recover: { sms: true }, // abandonment flow
});

Review
A person checks the application. If anything is missing we ask, not reject.
Activate
Your processing account appears as a route the moment it is approved.
“We were paying sticky.io for orchestration and two other tools for the rest. Certus replaced all three and cut the bill by about 60%.”
“Approval rate went from 78% to 91% in the first month once cascading was on. That's the whole margin of the business.”
“The dunning sequence recovered $47K in the first quarter. It was live before our email team had a ticket for it.”
