Frequently Asked Questions

General

What is RevKeen?

RevKeen is a billing platform that shows you what you actually keep. One-off charges, recurring subscriptions, invoices, and checkout links -- with real-time margin intelligence built in. API-first, developer-friendly, 1.7% transaction fees.

Who is RevKeen for?

Any business that collects payments and wants to understand their true margins. Two main groups use RevKeen:

Developers and companies building payment integration into their products -- SaaS, web apps, digital products. If you're on Stripe, Paddle, Polar, or Clerk Billing and paying 3.6-5%, RevKeen cuts that to 1.7% while showing you margin per customer and per product.

Service businesses with recurring billing -- healthcare, wellness, sports, coaching, beauty, co-working, or any business with memberships and repeat payments. If you want simple billing with transparent fees and a clear view of what you keep, RevKeen is built for that.

What makes RevKeen different?

Every billing platform shows revenue. Only RevKeen automatically tracks processing fees, gateway costs, and refund costs to show your true margin -- per transaction, per customer, per product. Plus you pay 1.7% instead of 3.6-5%.

How does the 1.7% compare?

On £10,000/month revenue, you save £3,000/year vs Stripe and £4,920/year vs Paddle.

Pricing

What does RevKeen cost?

Processing fee (all plans): 1.7% + £0.10 per transaction.

Platform plans:

• Standard -- £69/month (150 transactions, 10 invoices)
• Pro -- £119/month (450 transactions, 100 invoices)
• Unlimited -- £199/month (everything unlimited)

No hidden costs, no contracts, cancel anytime.

What does the 1.7% + £0.10 cover?

This is RevKeen's platform margin on top of your gateway/acquirer fees. Your total processing cost = gateway fees + RevKeen platform fee. There are no additional platform fees, billing fees, or hidden charges.

How does the marketplace work?

• Blocked -- upgrade your plan to unlock

Does RevKeen work with Stripe?

RevKeen is an alternative to Stripe, not an add-on. If you're currently on Stripe + Billing (3.6% all-in), RevKeen offers the same billing capabilities at 1.7% with margin intelligence that Stripe does not provide.

Does RevKeen work with my website?

Yes. Checkout links work on any website -- just share the URL. A WooCommerce plugin is coming soon. For custom integration, use the REST API, TypeScript SDK, or webhooks.

Margin Intelligence

What is margin intelligence?

Most businesses don't know their real cost per transaction. Processing fees, gateway charges, currency conversion costs, and failed payment retry costs all eat into your margin. RevKeen tracks every cost automatically and attributes it to the right customer, product, and transaction.

What does RevKeen track?

• Per-transaction cost -- the true cost of every payment
• Per-customer profitability -- which customers are actually profitable
• Per-product margin -- which products earn the most
• Cost attribution -- processing fees, gateway costs, refund costs
• Revenue and margin trends -- monthly charts and top customers by margin

Does any other platform offer this?

No. Stripe, Paddle, Polar, Clerk Billing -- none of them provide per-transaction cost tracking or margin intelligence. This is unique to RevKeen.

Security

Is RevKeen secure?

Yes. PCI DSS compliant payment processing, end-to-end encryption, per-tenant data isolation. Payment processing powered by Elavon.

Where is RevKeen based?

RevKeen Limited is incorporated and regulated in Jersey, Channel Islands. A trusted jurisdiction with strong financial services regulation.

Getting Started

How do I get started?

Three steps:

1. Create your account -- sign up, configure business details, connect payment processing
2. Set up your products -- create products, set prices, configure subscriptions, generate checkout links
3. Start collecting payments -- share checkout links, embed payment forms, or integrate via API

How long does setup take?

For checkout links and invoices: minutes. For API integration: depends on complexity. RevKeen is designed to go live quickly.

Do I need a developer?

No. The dashboard, checkout links, and invoicing work without code. For API integration, webhooks, or custom SDKs, developer resources are needed.
