ExpenseLink Offline

Description
The Gelco Expense Management division of Gelco Information Network Inc. is a market leader in outsourced expense report and payment management. The division of Gelco Information Network offers a thin client or web-based solution to corporate clients.

Many of their customers have found that a pure thin client solution is not acceptable in all situations for their business requirements.

Customers were requesting an application that had the same user interface as the familiar web based application, but one that could be used while disconnected from their network or their internet service provider.

Project
To develop a client side application, retaining the web based user interface, that would allow users to create and manage expense report documents while disconnected from their Internet Service Provider and that would provide a mechanism for synchronizing these Offline documents back to the online system.

Any proposed solution would also need to keep synchronized with the online system for account configuration changes, including new data validation requirements.

 

Solution

A set of client side and server side components were developed which provided the functionality required by Gelco's customers.

Of these components, the Offline Application Agent provides the offline "web serving" and synchronization functionality.  This agent is a small footprint Windows application responsible for handling the servicing of web requests when the user is disconnected and for caching expense documents offline until the user chooses to upload them to their online system.

Watch this space for more information on this truly unique project in the coming weeks.
