Redesign
Before & after: the Marzley Tech website
The old site became this one: a cleaner layout, faster pages and the tools clients actually use. Drag the handle to compare.
- Faster on mobile data
- Clearer menu and pages
- Live M-Pesa payments
- Dark mode and accessibility
02 — Payments integration
We add M-Pesa payments to your systems
Shops, schools, hospitals, Wi-Fi hotspots: we connect your system to M-Pesa so customers pay from their phones and every payment is confirmed automatically. Try it yourself: enter your Safaricom number below and you’ll get the same prompt your customers would see.
- Checkout sends an STK push request to Safaricom.
- The phone shows the M-Pesa PIN prompt.
- Confirmation arrives by SMS and the order updates automatically.
This is a real payment of KSh 1 to Marzley Tech Solutions (Till 6095737). Enter your PIN only in the M-Pesa prompt on your own phone, never on a website.
M-PESA
Do you want to pay Ksh 100.00 to MARZLEY TECH?
Check your phone
Enter your M-Pesa PIN in the prompt on your phone to pay KSh 1.
