Offshore can be the smartest decision you make — or the most expensive mistake. The difference is rarely price; it is how the partner is run. Here is the checklist we would use.

1. Seniority and named people

Ask exactly who will work on your project, their experience, and whether they are named and stable — or a rotating pool of juniors. You want product-minded seniors who stay.

2. Real communication and timezone overlap

Daily overlap with your hours, fluent English, and a named point of contact are non-negotiable. Async-only across a 12-hour gap slows the feedback loop.

3. Quality that is built in, not bolted on

Ask how they test. A serious partner integrates manual and automated testing into every sprint rather than a single QA pass before release.

4. Delivery discipline

Look for structured project management: a real plan, roadmap, risk log and honest status. Engineering talent is not the same as delivery discipline.

5. Security and IP

NDAs as standard, full IP assignment to you, and GDPR-aware data handling should be table stakes — confirmed in writing, not promised verbally.

6. Proof you can check

References, case studies and the willingness to put you in touch with past clients. Be wary of inflated stats and logos a partner cannot substantiate.

The short version: hire for delivery discipline and seniority, verify everything, and treat price as the last filter, not the first.
