Introduction
Billing, payments, and margin intelligence for your business.
What is RevKeen?
RevKeen brings billing, payments, customer operations, and margin reporting together. Use the dashboard to run your business, or connect your own application through the API, SDKs, and webhooks.
Create products and subscriptions, collect payments, manage invoices, and understand how payment costs affect the revenue you keep.
What can you build?
Subscriptions and recurring billing
Manage subscription lifecycles, plan changes, renewals, and failed-payment recovery.
Checkout and payment links
Give customers a hosted checkout experience or integrate payment flows into your application.
Invoices and customer operations
Manage invoices, orders, customer records, and self-service journeys.
Usage-based billing
Meter consumption and connect usage to your pricing and billing workflows.
Direct Debit
Request mandates and manage collections through your London & Zurich provider account.
Margin intelligence
Bring revenue, provider fees, refunds, and settlement information into your reporting.
How RevKeen fits your business
Your business holds its own payment-provider accounts. RevKeen supplies the software and orchestration around those relationships, including Elavon/NMI for card payments and London & Zurich for Direct Debit where configured.
RevKeen is not your merchant of record. Your business retains its customer, tax, and ordinary chargeback responsibilities. Platform fees and provider charges are separate; see Fees for the current pricing and scope.
Choose your starting point
If you are setting up your business, begin with account setup and provider onboarding. If you are building an integration, start with a staging key and a read-only API request.
Integrate the API
Configure billing
Handle webhooks
Make your first staging request
Set your staging API key in your server environment, then list customers. A matching key returns 200 OK with a list payload.
export REVKEEN_API_KEY=rk_sandbox_your_api_key

Find your way around
Use the left menu to browse guides and reference pages. Search finds documentation and API operations. The On this page outline on the right shows your position within the current article; on smaller screens, open its page-outline menu.
The public RevKeen Assistant answers documentation questions. It has no access to your merchant account. For account-specific help, use Support.
