STK Push

An M-Pesa payment method where the customer receives a prompt on their phone to authorise payment by entering their PIN, rather than manually entering a Paybill or Till number.

In plain terms

The payment method where the customer receives a prompt on their phone and authorises by entering their PIN, instead of leaving your checkout to enter a Paybill or Till number manually.

It converts better than manual entry because it removes the step where people leave the page, mistype a number, or forget the reference.

Why it matters in Kenya

For most Kenyan online stores it should be the default checkout method, with manual Paybill offered as a fallback for the cases where the prompt does not arrive, which does happen.

What to do about it

Four checks you can run on your own site this week.

  • Make it the default, with manual details visible as a fallback
  • Show the customer what to expect: a prompt, then a confirmation
  • Handle the timeout case explicitly rather than leaving the order in limbo
  • Reconcile automatically against the order, not by eye at the end of the day
