In their own words
Master Lab ScientificView project ↗
“Managing operations becomes challenging when you have a distributed team working across different parts of the world. Tranz Technologies took the time to understand our challenges, workflows, and operational needs, and built the right ERP solution for us.
Today, most of our processes are automated with very little manual intervention. Our sales, purchases, enquiries, and other key operations are now tracked and managed through a single platform, making it much easier for our team to work efficiently and maintain complete visibility across the business.
Great work by the Tranz Technologies team.”
Rajesh KrishnaFounder, Master Lab Scientific, Dubai
A2A HolidaysView project ↗
“Per-user licence costs had become a major concern for our sales team of more than 30 people. We had already tried several CRM products before Tranz Technologies proposed a custom solution that we could fully own, without ongoing per-user licence fees.
The CRM is now built around our actual sales workflows and gives us the flexibility to add more users as our team grows. Having complete ownership of the platform has been a real advantage for us.”
