Accounting in multiple countries
As Tech Mahindra expanded, managing tax accounting and e-invoicing across multiple countries became increasingly complex. “It becomes quite complex to kind of, you know, navigate. And then I think a product like Thomson Reuters has been... instrumental in enabling, the kind of seamlessness that we expect,” says Sarao. The company also underwent significant internal transformation, including a new CEO and management team, and a renewed focus on agility and technology adoption.
“We've now developed a 360 degree partnership. What that means is, whilst Tech Mahindra does technology work for Thomson Reuters, we are ourselves users of the ONESOURCE technology.”

360-degree partnership
Tech Mahindra’s partnership with Thomson Reuters spans 25 years, evolving into a “360-degree partnership.” “We've now developed into a 360 degree partnership. What that means is that whilst, Tech Mahindra does... technology work for Thomson Reuters... we've also ourselves users of the one source technology,” Sarao explains. Tech Mahindra was among the first to implement ONESOURCE Pajero after its acquisition, supporting both internal operations and client solutions. The partnership extends to co-selling and joint market expansion, especially in emerging markets like the Middle East, Africa, and Asia.
While the transcript does not provide specific quantitative metrics, it highlights strategic and operational benefits:
- Tech Mahindra’s teams are “extremely appreciative of, the kind of, benefits that they've seen in the tax accounting space or in the e-invoicing space of having implemented Thomson Reuters Solutions.”
- The partnership has enabled success in oil and gas, financial services, and ERP transformation projects in the UK and Europe.

Data accuracy that you can rely on
Sarao emphasizes the value of Thomson Reuters’ technology investments and integrated product suite: “What I tell my clients... why they should, select Thomson Reuters products and work with them is because they have an extremely great... story in terms of the data accuracy... and also the kind of artificial intelligence enabled products that they have come out with in the market, which are really best in class.” The partnership has also fostered a culture of trust, innovation, and continuous learning, with Tech Mahindra sponsoring and participating in Synergy, Thomson Reuters’ flagship customer event.
