First Line Software was engaged to develop new functionality for what was a static portal to automate the ability for customers to order and pay for a range of services as well as maintain and optimize the performance of the system.

The client

Our client is the largest logistics enterprise operating with 41,900 post office locations and 350,000 employees. It provides a wide range of services including domestic and international parcel delivery, mail, acceptance of payments, pensions and allowances payments, and money transfers, to one billion customers annually.

Previously, our customer’s Internet presence was simply a static information site. The company needed to start providing customer service capabilities. Users of this interactive client portal were able to calculate postage and shipping costs, track packages, and search for specific post office locations by entering certain parameters, and order courier deliveries.

While the client’s portal had an impressive list of services from the start, it quickly became necessary for the site to be in constant state of development. There has been a continuous flow of new services and capabilities requests to be built and implemented.

Project scope

First Line Software was engaged to develop new functionality for what was a static portal to automate the ability for customers to order and pay for a range of services as well as maintain and optimize the performance of the system.

The solution

A First Line Software team of specialists implemented several major improvements to the customer’s portal:

• No form required for parcel mailing

When calculating the delivery cost of a mailing, the user can assign a parcel track number through the Portal. The only thing left for them to do is hand off the item to the post office or request a courier to pick up and mail or deliver the item.

• Online payment

Initially, only Moscow residents could use the portal to make payments for mail and shipping costs. Over time, the customer started supplying the necessary equipment to other post offices and regions. This made it possible to simultaneously expand the service of accepting online payments on the portal to other residents in the country.

• Prompting and geolocation service

Specific prompts related to entering addresses online were developed instead of using third-party commercial products. The customer's address was verified with an internal online service which validated the address information entered by the user and notified users of incorrectly entered address information, then integrated the data with any forms.

• Request a courier

The portal user can submit a request for a courier to pick up and deliver the mail or package by completing a simple form.

• Delivery to the postamat (automated parcel terminal)

This function allows the client to order mail delivery to the postamat using an application form on the portal which also allows them to track the delivery status to the terminal.

• User’s postcards

The user can use their own design elements to create a postcard and order it to be mailed.

• SMS notification of delivery status

For convenient tracking of the mail or package, the user can request SMS notification of the delivery status.

The result

During a period of six months FLS implemented and scaled up several important business functions for the customer’s portal. Their ability to complete the project within a short period of time was due in part to the team’s technical expertise, as well as a customized and continuously optimized flexible development process.
