The bottom lineOffshore for spec-able work; onshore-senior for outcomes.
Choose on the shape of the work, not the rate card. Well-specified, repeatable production work — where the brief is unambiguous and you have the internal capacity to QA it tightly — is exactly where offshore can shine, and choosing it there is smart. Strategy, judgement, and anything that iterates fast against real data is where a twelve-hour gap and thin context quietly destroy the saving.
The expensive mistake is picking on hourly rate alone. The cheap rate isn’t the real rate once you add the rework loop: a lost day per clarification, work that’s technically to-spec but wrong, rounds of QA, and the management time to hold it all together. Cost per shipped result is the number that matters, and it’s often higher — just spread across your calendar instead of your invoice.
Our recommendation: keep the work that decides your outcome close, senior and accountable — a small team in your timezone that owns the number and lands it the first time — and reserve offshore for the well-defined production work it genuinely suits. Fewer people, closer, owning the result usually costs more per hour and noticeably less per outcome.
