Cost is the most cited reason. As of September 2026, agency-delivered market ranges for senior developers run about $35–55 an hour in India and $30–50 in Southeast Asia, against $150–250 in the US and Canada. Those are market ranges rather than quotes, and the total cost of an engagement also depends on management overhead, rework and communication.
The main challenge is distance. Large time-zone gaps limit real-time collaboration, so offshore work goes best with written specifications, a short daily overlap window, automated tests and code review on every change. Teams that rely on quick hallway conversations to resolve ambiguity tend to struggle with offshore delivery until those habits are replaced by documented ones.
Cost advantage
Hourly ranges well below US and Canadian rates for comparable seniority.
Time-zone gap
Working hours may barely overlap with the client's, so overlap must be planned.
Process-dependent
Works best with clear specs, async communication and strong code review.
