Clients ask us this more than almost anything else, and the honest answer is that the hourly rate is the least useful place to start. The right model depends on how much the work needs your people in the room, and how well it is specified.
Onshore fits work that is ambiguous, customer-facing, or changing weekly: discovery, architecture, anything where a five-minute conversation saves a day of rework. You pay more per hour and usually less per outcome, because decisions happen in real time.
Nearshore fits work that needs collaboration during your day but not your office: product development with daily standups, QA that runs alongside your developers, support that overlaps your business hours. Time-zone overlap is the whole value, so check it hour by hour, not country by country.
Offshore fits work that is well specified and benefits from a longer working day: regression testing overnight, steady feature delivery against a clear backlog, maintenance and support of stable systems. It goes wrong when teams try to offshore ambiguity. Specs that were vague onshore do not get clearer twelve time zones away.
Most successful programs blend them. A common pattern: an onshore lead who owns requirements and client communication, a nearshore or offshore team that builds and tests, and a weekly demo of working software that keeps everyone honest. The lead is the part people try to cut to save money, and it is the part that makes the savings real.
Whatever you choose, agree three things up front: who decides when requirements are unclear, how quality is measured before work is accepted, and what overlap hours are protected. Bring us the actual project and we'll tell you which mix we'd pick, including when the answer is 'keep it in-house.'
