Mobile devices and wireless technologies have come to make a great impact on our lives. Mobile devices have been widely used in the last few years which have led to the e-revolution. This suggests the electronic mode of payment in sustaining the new innovations. The manual payment system has been revealed to be associated with a numbers of problems such as fatigue of standing in long queue, human error, forgery and lots more. This made a number of authors to have suggested electronic payment system with proven advantage in terms of accuracy, speed, cost and security. The Electricity Holding Company of Benin Republic (EHCB) is currently facing a lot of challenges using manual payment system which has made the stakeholders in company to suggest mobile payment system as an alternative. This informs the aim of the researcher to develop an m-payment prototype for EHCB and confirm its usability. The prototype was developed based on prototyping model using WINDEV while the usability was tested using an adapted survey questionnaire with ten metrics. It was discovered that the developed m-payment prototype for Electricity Holding Company of Benin Republic is usable.
