Frequently Asked Questions

Below you will find the most common questions we get asked when using prepayment in general, and the advantages Nectar© has over traditional prepayment software.

  • What is prepayment and how can it help me as a service provider?

    Prepayment is a mode of payment where you as a service provider receive payment for your service before consumption. Using Nectar©, you as a service provider offering electricity, water or gas, no longer have to chase for payment. Instead, your customers pay for your services before use, based on rates that you set using the Nectar© Dashboard. They then receive tokens (20 digits numbers) via the web and SMS for a volume commensurate to their payment. Your customers then enter these tokens a prepaid meter that monitors consumption until the volume procured is exhausted, after which your customers have to procure additional tokens again. Nectar© supports the latest version the most pervasive prepayment standard in the world called the STS standard (IEC 62055-41:2018).

  • Other token generation system are large, expensive enterprise applications that require a data center, hardware security modules and 3rd party payment gateways before they can receive payments and generate STS prepaid tokens. In addition, they lack a rich web and USSD platform through which the utility and their customers can procure tokens and monitor consumption. Nectar© however, is a cloud based application that requires no set up to begin using prepayment. Simply create an account as a service provider for you and your customers and you are good to go! In addition, Nectar© includes a rich web dashboard as well as payment integration via MPESA. Therefore, for service providers with STS certified prepaid meters, they can begin to use Nectar© immediately and begin receiving payment for their service before use.
