A complete, ready-to-use online card payment system installed on your existing website. Your visitors enter their card details in a secure bank-branded checkout panel without ever leaving your site, the payment is processed securely through your bank on the Cybersource global payment network, and the money lands in your merchant account.

It works for donations, service payments, product sales, bookings — any situation where you want to be paid by card online.

Proven, not promised

This is the exact system we designed, built, deployed, and verified end-to-end for Ultimate Wings Kenya (www.ultimatewings.co.ke). The reference installation passed a live end-to-end test: checkout opened on the site, a test card was authorized by the bank network (approval code issued, card and address checks matched), and the donor landed on a branded success page with a real transaction reference — all in under a minute.

Two packages — which one is yours?

The right package depends on how your website is built. We confirm which applies during a free 10-minute look at your site before any work begins — the price you are quoted is the price you pay.

Key capabilities

💳

Visa & Mastercard out of the box

With support for Google Pay and Apple Pay where enabled on your merchant account.

🔒

PCI-safe by design

Card numbers are entered into the bank's own secure fields and tokenized — your website never sees, stores, or transmits raw card data.

🛡️

3-D Secure built in

The extra bank security layer (OTP/verification) runs automatically whenever the card issuer requires it.

Server-side verification

The success page is only shown after the bank confirms the authorization — eliminating fake "success" screens.

🇰🇪

Kenyan-ready

KES currency, en_KE locale, phone and email capture for your records and reconciliation.

🧪

Test mode included

You and the bank can run unlimited test transactions — no real money moves — before going live.

📱

Works alongside M-Pesa

Keeps your existing Paybill/Till options; card payments are added, nothing is removed.

Payment terms — both packages

65% on engagement to begin the build, 35% on demonstrated completion (a live test-mode transaction on your own website). You see it working before the final payment. Market context: comparable custom payment integrations in Kenya are typically quoted at KSh 20,000–50,000+ by established providers — our custom package starts at KSh 25,000 and includes the verification report and handover that others bill separately.

What we need from you to start

  • Access to your website hosting or admin panel (or we set up a new one for you)
  • Your bank's merchant credentials — test-mode first; the bank provides a simple key file and we guide you through it
  • Your logo and brand colours, if the checkout pages should match your site
