Nearshore vs Offshore Development: The Overlap Math Nobody Publishes

We are an offshore development company in Mumbai. What follows makes the case against us for roughly half of the people who read it, which is the point. The nearshore versus offshore argument is usually made by whichever side is writing, and the number that actually decides it is almost never printed.

Here is that number.

Hours of live overlap, by pairing

Both sides working 09:00 to 18:00 local, northern hemisphere summer:

Your team is in	India	Poland / Ukraine	Colombia / Peru	Brazil / Argentina
US East Coast	0h	2.5h	8h	8h
US West Coast	0h	0h	7h	5h
UK	4.5h	7.5h	3h	5h
Australia (east)	4.5h	1.5h	0h	0h

Read the first column twice. On standard business hours, an Indian team and a US team share no working time at all. Not a little. None. Every offshore vendor selling to the US is either shifting staff onto night hours or quietly running an async process and hoping you do not notice which.

The second thing to notice is that no column wins everywhere. Latin America is unbeatable for US clients and useless for Australian ones. Eastern Europe is the best answer for the UK and a poor one for the US West Coast. India is the only column that is workable for both the UK and Australia. There is no globally correct answer, only a correct answer for where you sit.

The rate gap is smaller than it looks, and it is not the deciding factor

Nearshore costs more per hour than offshore. That gap is real, and on a long engagement it is the difference between four engineers and six. But rate is a bad primary criterion, because the cost of a badly run project dwarfs the rate difference on a well run one. A team that is 30 percent cheaper and ships 50 percent slower is not cheaper.

The thing to optimise is not hours purchased. It is decisions per week.

The actual deciding question

Count how many times in a normal week your team needs a synchronous decision from someone on the other side. Not a status update. A decision: an ambiguous requirement, a design tradeoff, a production incident, a stakeholder changing their mind mid-sprint.

More than five a week. You need real overlap. Choose nearshore, or choose onshore. An offshore team will spend its life waiting on you, and you will spend yours writing clarifications at midnight. No amount of process fixes a structural four hour gap between question and answer.

One to five a week. Either model works, and the decision comes down to rate, available skills and how disciplined your written communication is. This is where most product teams actually sit, and it is where offshore usually wins on economics.

Fewer than one a week. Offshore is the obvious answer. Well specified work with clear acceptance criteria does not need a shared clock. You are paying a nearshore premium for a meeting you would not have taken.

Most teams guess high on this number. Before committing to a model, log it for two weeks. The result is often a third of what people expect, because a lot of what feels like a decision is actually a notification.

When nearshore is the right call

Be honest about these, because they are common:

• You are pre product-market fit and requirements change several times a week
• You have no written specification culture and are not going to build one for this project
• Your work is incident-heavy, with production issues needing same-hour response in your business day
• Your team is small enough that one senior person holds all the context in their head
• Regulatory or client contracts require staff in specific jurisdictions

In every one of those cases, hire nearshore. We will tell you the same thing on a call.

When offshore is the right call

• Your scope is stable enough to specify a sprint ahead
• You need a skill that is scarce and expensive in your market and abundant in ours
• You are in the UK, Europe, the Middle East, or Australia, where the overlap column is workable without night shifts
• You want more engineers for the same budget and can absorb a one day round trip on non-urgent questions
• You are building something long-lived where continuity of the same engineers matters more than instant response

If you go offshore, the protocol matters more than the vendor

The failure mode is never the code. It is the round trip. Teams that make offshore work do four things.

Book the overlap and treat it as sacred. Whatever hours you share, they are for decisions, not status. Status goes in writing. If your only shared 90 minutes gets eaten by a standup that reads out a board everyone can see, you have wasted the scarce resource.

Write acceptance criteria before work starts, not after it fails. The cost of ambiguity scales with the size of the time gap. Onshore, a bad ticket costs ten minutes. Offshore, it costs a day.

Batch your questions. An offshore team that gets one well-formed list of eight questions at the start of their day will answer all eight. The same eight arriving one at a time across your afternoon will get answered tomorrow.

Insist on the same people. Rotating engineers destroys the context that makes async work possible. Ask any vendor what their annual attrition on a given account is, and be suspicious of a vague answer.

What we actually do about the US column

Our standard day is 10:00 to 19:00 IST, which is fine for London, Dubai, Singapore and workable for Sydney. It is useless for the US, so we do not pretend otherwise. Our New York team runs 12:00 to 21:00 IST, which produces a 2.5 hour live window from 09:00 ET. For Pacific clients we run 14:00 to 23:00 IST and get roughly 90 minutes.

That is a real cost borne by real people working evenings, and it is why we are straightforward that a Bogota team will give a San Francisco client seven hours and we will give them ninety minutes. If those seven hours are what your project needs, buy them.

Where we work and what the overlap is in each city is on our locations page, and the work itself is on services. If you want to talk through which model fits, contact us and we will say so honestly, including when the answer is not us.
