Business Challenges

Controlling Issues during Billings: Praxair delivers highly delicate and inflammable gases. Also produces mixtures of helium, hydrogen, xenon, krypton upon client’s demand. The company planned to launch an app to mitigate the risks associated with the changes in billing.
Reduce Billing Cycle: Praxair was facing the issue in getting the invoice paid on time as that was taking a nearly month time for getting the credit confirmation on the goods delivered.
Track and Control: The app should track and control the vehicle movements to establish a communication between the driver and agent.
To overcome these three different business challenges, the company wanted to find one best solution and approached USM to develop an innovative app that deals with the above challenges.

Our Solutions

After a comprehensive discussion with Praxair, USM proposed an idea which connects all truck drivers’ with the back end server using multiple mobile technologies. Since security is vital during all phases of communication, all the devices with IMEI are registered with the service to prevent unauthorized devices from communicating with the back end server.
Truckers carry mobile devices which enable them to perform the following:

  • Know the customer(s) Trip activity
  • Record In/Out timestamps on Arrival/Departure
  • Capture readings when offloading
  • Read the Bar Codes
  • Take snapshots of the Challan (token)
  • Send the data to the back end

Benefits Delivered

Praxair reduced the invoice billing cycle up to 72%.

To capture trip activities on the move and know the updates throughout the trip.
