Postpaid Bolt-On Feature Launch

We're excited to launch a new feature within EAP - Postpaid Bolt-Ons.


This feature allows MVNO's to offer bolt-ons to their postpaid customers.

Bolt-ons are not only an additional revenue source for MVNO's, but ultimately give the customer the freedom to manage their additional usage and costs, and continue to use their service once they've reached a usage limit. A bolt-on increases the allowance and bar limit for a particular usage type on a service for the current billing period.

Continue reading below.

EAP's Postpaid Bolt On Management Interface

The feature can be broken down into a few easy steps:

  1. Create bolt-on - We carefully designed the postpaid bolt-on creation process so that it is quick and simple for MVNO's. For consistency, the interface follows EAP's standard design which is built using Bootstrap.
  2. Configure for automation (optional) - MVNO's can configure a retail plan with a bolt-on that will be automatically adding to a service upon reaching the defined usage limit on a particular usage type, allowing uninterrupted usage for a client. The number of recurrences per-billing cycle can be configured. It is possible for a customer to opt-out of automated bolt-ons on a per-service basis.
  3. Add to a service - A postpaid bolt-on can be added to a service either manually by the customer via the MVNO's website or app, automatically by EAP, or manually within EAP via the MVNO's customer service team.

System/Technical Features

As a team, we scoped, designed and developed the feature to be super flexible and easy to use for both MVNO's and consumers.

  • Technically, the feature has been built using Bootstrap, jQuery, and Adobe ColdFusion, and carefully integrated within EAP's provisioning, CRM and fully-automated billing system.
  • EAP's postpaid billing system automatically takes care of passing on costs to the customer on creation of their next postpaid invoice.
  • EAP's job queueing system is utilised for adding bolt-ons which ensures bolt-ons are added in a timely manner and allows monitoring and alerting to be undertaken.
  • Extensive logging is in place to track bolt-on activity on a per-service basis. EAP users can view this information directly within EAP to assist customers if need be.
  • Bolt-on history is shown in EAP on service management pages.
  • Automatic unbarring is in place for when a bolt-on is added for a usage type that is barred.
  • Extensive validation processes are in place to ensure bolt-ons are only added where they are supported by the service in question.
  • EAP's API / web service can be utilised to return information to a customer such as what bolt-ons are available to purchase for their service.
  • MVNO's can customise bolt-on related consumer-facing messages using EAP's System Communications management tool.

All in all, we learned a great deal and found ways to maximum existing code and systems to fast-track the development and launch of this handy new feature.
