OES has been our trusted technology partner for over 8 years. Their installation teams are professional, their machines are reliable, and their after-sales support is unmatched in Pakistan. We have expanded our contract with them across 40 of our branches.

The 300KW solar installation at our Sheikhupura plant was delivered on time and under budget. The OES team's technical expertise and project management is genuinely world-class. Our electricity costs dropped by 65% in month one.

Our cash operations have been transformed since OES installed and now maintains our counting and sorting machines. Accuracy is at 99.99% and downtime is virtually zero. I recommend OES to every bank I speak to.
