FAQ
Frequently asked questions
What is the difference between a Paybill and a Till number?
A Paybill asks the customer for an account number, which suits invoices and rent. A Till number is for simple purchases with no account number.
What is an STK Push?
It is a prompt sent to the customer’s phone to approve an M-Pesa payment, so they do not type paybill details.
Do I need an SSL certificate?
Yes. It secures your website and shows the padlock in browsers. Our hosting includes free SSL.
