RevKeen Documentation
Know what you keep, not just what you earn. The billing and payments platform with acquirer-level margin intelligence — built on Elavon and NMI, with no merchant-of-record markup.
Know what you keep, not just what you earn
RevKeen is a billing and payments platform that connects billing operations with transaction, provider-fee, and settlement data. Your business holds its own Elavon/NMI and/or London & Zurich provider accounts; RevKeen supplies the software, orchestration, and Margin Intelligence around them.
Why RevKeen
See your real margin
Connect provider costs, refunds, recovery activity, and platform fees to revenue. Know your net revenue per customer, product, and transaction — not just gross volume.
You own the merchant relationship
RevKeen is not a merchant of record or a payment facilitator holding sub-merchants. You hold your own provider accounts and retain the customer, tax, and ordinary chargeback relationship.
The full billing suite Polar doesn't have
Automated dunning with smart retries, customer health scores, wallet credits, Direct Debit (London & Zurich), card-present terminals (PAX A920 Pro), and a branded customer portal. Enterprise-grade billing operations, without enterprise pricing or a procurement cycle.
Published platform pricing
RevKeen separates its platform fees from the gateway, acquirer, scheme, interchange, and bureau costs charged under your own provider agreements.
RevKeen plans: Standard £69/mo (150 txn), Pro £119/mo (450 txn), Unlimited/Scale £199/mo unless commercially agreed otherwise. Platform transaction fees, add-ons, usage overages, and costs charged under your own provider agreements are separate. See the versioned Fees page for the current authoritative amounts.
What RevKeen handles
Billing automation — Recurring subscriptions, usage-based metering, one-time invoices, and automated dunning so you collect more revenue with less manual work.
Payments — Hosted checkout pages, payment links, card-on-file renewals, refunds, voids, Direct Debit, and card-present terminals — all routed through your Elavon merchant account with NMI as the gateway.
Customer operations — Health scores, a self-service customer portal, wallet credits, and multi-channel notifications (email, SMS, WhatsApp) to keep customers informed and engaged.
Margin intelligence — Connect provider costs, settlements, refunds, and RevKeen fees to revenue for transaction-, product-, and customer-level analysis.
Integrations — Connect CRMs, accounting tools (Xero, QuickBooks), practice management systems (PracticeHub, Wodify), tax automation (Quaderno), and custom workflows via webhooks and our REST API.
