An offshore hiring model is the arrangement that decides who finds, employs, equips and manages the people doing your work in another country. The five common models are a dedicated team, freelancers, an employer of record, project outsourcing and a Global Capability Center.
Start with one question: do you want to buy an outcome or build a team? If you want a finished deliverable and do not need the knowledge afterwards, outsourcing or freelancers can work. If you want people who learn your product and stay, you need a dedicated team, an EOR hire or a GCC.
Then weigh the trade-offs. More control usually means more management work for you. Faster starts usually mean less screening, unless someone has done the vetting in advance. Lower headline rates often hide costs in rework, turnover and your own time.
