Onshore vs Nearshore vs Offshore Software Development: A US Buyer's Comparison

Three labels, four real options

The labels describe distance, measured in time zones. For a US buyer they map onto regions like this:

• Onshore: a team in the US, either your own hires or a US agency. Same hours, same law, same language, highest cost.
• Nearshore: Latin America. Mexico, Colombia, Costa Rica, Brazil, Argentina, Chile, Uruguay. Zero to three hours from US Eastern time. Our explainer on what nearshore software development is covers the definition in more depth.
• Offshore with partial overlap: Central and Eastern Europe. Poland, Romania, Czechia, the Baltics, Ukraine. Six to seven hours ahead of New York, with a fixed daily window of shared time.
• Distant offshore: India, Vietnam, the Philippines and the rest of Asia. Nine and a half to twelve hours ahead of New York, with little or no shared time unless someone works nights.

Lumping CEE and India together as "offshore" hides the most useful distinction for US companies. A team in Kraków and a team in Bangalore differ on rates, overlap, travel and working style almost as much as Kraków and Mexico City do. So the rest of this article compares four columns.

Cost: rates, then total cost

Rates are the easy part. We publish detailed ranges by country and role in our nearshore software development rates guide; here they are per senior engineer per year, at 1,920 billable hours (160 a month, twelve months).

The US loaded figure starts from the BLS median software developer wage of $133,080 (May 2024) and adds 25–40% for benefits, payroll taxes, equipment and recruiting. Senior engineers in New York, Seattle or the Bay Area cost well above it.

The last column is where cheap rates leak. Distant offshore engagements with thin specifications can easily lose a fifth or more of their hours to rework and clarification. That doesn't make distant offshore a bad choice. It means the saving belongs to teams that can write precise tickets and review work carefully. If you can, an Indian vendor at $35 an hour is hard to beat on cost.

Overlap: what the time zone does to cycle time

Overlap is the factor that separates the four options most, and it's easy to underestimate in a sales call. The shared hours with a 9:00–18:00 day in New York:

Here's what that means in practice. A developer hits an ambiguous requirement at 14:00 their time. With a Latin American team, they ping the product owner and have an answer within the hour. With a CEE team, 14:00 in Warsaw is 08:00 in New York; if the product owner checks messages early, the answer arrives before the overlap window closes; if not, the developer works on something else and picks it up the next morning. With a team in Bangalore, 14:00 is 03:30 in New York. The answer arrives the next day.

West Coast companies should redo the math: Latin America still gives 5–8 hours (Mexico is one to two hours from Pacific time), CEE gives 0–2, and India gives about the same unless the vendor runs a late shift, which many Indian vendors do for US clients.

Overlap matters less than it seems if your work is well specified and your team writes things down. It matters more than it seems if decisions happen in conversations. Be honest about which kind of team you are.

Talent pool and seniority

All four regions have plenty of developers. The question is how many senior engineers in your stack you can actually get, and keep.

• US: the deepest senior market in the world, and the most expensive. Hiring a senior engineer can take three to four months.
• Latin America: roughly two million developers across the region, with Brazil and Mexico the largest pools. Strong in web, mobile and mainstream backends. Senior engineers with US-client experience are in demand from both vendors and US companies hiring directly, so retention depends heavily on the vendor.
• CEE: deep senior benches in backend, data, embedded and complex systems, a long tradition of strong technical universities, and good English. Poland alone has several hundred thousand IT specialists.
• India and Southeast Asia: the largest absolute pool by far, with excellent engineers at the top end. Quality varies more between vendors than in other regions, so vetting matters most here.

Legal, IP and compliance

All three outsourcing options can be contracted safely, but the details differ.

• Onshore is simplest: US law, US courts, US persons. It's the only realistic option for work under ITAR, many federal contracts and some data-residency requirements.
• Latin America: contract with the vendor's US entity where possible, under a US state's law. Local labor law is strict in Mexico and Brazil. Mexico's 2021 outsourcing reform requires vendors providing specialized services to register with the labor ministry (REPSE), so ask for the registration. Make sure IP assignment flows from each engineer to the vendor to you.
• CEE: EU vendors operate under GDPR, which helps if you handle personal data, and EU IP law is strong and enforceable. Many CEE engineers work as B2B contractors, so the vendor's contracts with its people must assign IP explicitly.
• India / Asia: large vendors have mature compliance (SOC 2, ISO 27001) and standard IP assignment. India's 2023 data protection law adds obligations if personal data is processed there.

In every case, the protections live in the contract: IP assignment, confidentiality, data processing terms, replacement and exit rules. Our software outsourcing contract guide lists the clauses to check, and the outsourcing risks article covers what goes wrong when they're missing.

Communication, culture and travel

English is native onshore, generally strong in CEE and at top Indian vendors, and uneven in Latin America: EF's 2025 English Proficiency Index puts Argentina first in the region and 26th worldwide, while Mexico, Brazil and Colombia sit in the low band nationally. At good vendors the engineers you talk to daily speak well, but test each person.

Feedback style matters more than accent. CEE engineers tend to be blunt about bad requirements, which some US managers find refreshing and others find abrasive. Teams in parts of Latin America and Asia may be slower to say "this won't work" to a client, so you need to ask directly and make it safe to disagree.

Travel decides whether in-person time happens at all. Mexico City is two to five hours from most US hubs; Bogotá is under four from Miami; São Paulo is about ten from New York. Warsaw is eight to nine hours from New York and needs a connection from the West Coast. Bangalore is 17 hours or more with a connection. A quarterly trip for two people costs roughly $2,000–4,000 to Latin America, $3,000–6,000 to Europe and $4,000–7,000 to India, plus the days lost to jet lag.

The full comparison

Weigh the factors for your own case

Set how much each factor matters to you, from 0 (irrelevant) to 5 (deal-breaker), and where your team sits. The scores behind each option are our 0–5 ratings from the sections above, adjusted for your time zone. Treat the result as a structured gut check, not a verdict.

Two patterns show up when we run this with clients. If cost and senior depth carry the weight, CEE and Latin America finish within a few points of each other, and the time zone decides. If overlap carries a weight of 4 or 5 and the team is on the West Coast, Latin America wins clearly, and we say so.

The hybrid most US product companies end up with

Few companies pick one column for everything. The setups that work best assign each kind of work to the model whose trade-off suits it.

The catch: every extra team adds coordination. Two outside vendors plus an in-house team means three sets of rituals, three code review cultures and handoffs between them. Below about 15 engineers in total, one partner usually beats two. For team-level setup, see our guides on dedicated team structure and managing a dedicated team.

Where Central and Eastern Europe fits, honestly

CEE is offshore for US companies. We'd rather say that plainly than call ourselves "nearshore-ish". The region makes sense for US buyers when three things are true: the team can live with a fixed daily overlap of two to five hours, it works from written tickets and async code review, and it values senior engineering depth over constant availability. East Coast companies fit that profile far more often than West Coast ones.

It's the wrong choice when your product owner wants engineers in every afternoon meeting, when your team is in California and nobody wants 7:00 calls, or when your process relies on quick hallway decisions. In those cases a good Latin American vendor will serve you better, and the rates will be about the same.

FAQ

Where Gilzor fits

We're a CEE vendor with engineers in Poland and Cyprus, so we sit in the third column. For US clients we agree an overlap window up front (typically two to four hours with the East Coast, more with a shifted schedule) and run the rest of the day on written handoffs and async review. We start development within two weeks of signing, and 85% of our customers come back for more work.
