Once you decide to build a dedicated offshore engineering team, the next question is ownership. Do you want a partner to run the centre for as long as you need it, or do you want to own it eventually?

This guide compares BOT vs managed engineering centre models to help you choose.

Once you decide to build a dedicated offshore engineering team, the next question is ownership.

What is a managed engineering centre?

A partner employs the engineers and runs the centre, including entity, HR, payroll, facilities, IT and compliance, for as long as the engagement continues. Your engineering leadership directs the team's work, priorities and standards. You keep strategic oversight without carrying the administrative burden.

What is Build-Operate-Transfer?

The partner builds and operates the centre, then transfers the entity, team and processes to you at an agreed milestone. After transfer, it becomes your captive centre. Read the full BOT model guide.

BOT vs managed: side-by-side

Factor	Managed engineering centre	Build-Operate-Transfer
Long-term ownership	Partner	You, after transfer
Admin burden (HR, payroll, compliance)	Partner, permanently	Partner, then you
Day-to-day engineering direction	You	You
Flexibility to scale down	High	Lower after transfer
Cost structure	Ongoing monthly fee	Monthly fee, transfer fee, then direct costs
Time horizon	Any	Typically multi-year
Best for	Teams that want focus on engineering, not operations	Organisations building a permanent regional presence

Side-by-side comparison. Managed engineering centre: partner owns the centre and carries HR, payroll and compliance permanently, high flexibility to scale down, ongoing monthly fee. Build-Operate-Transfer: ownership and HR, payroll and compliance switch from partner to you at transfer, flexibility to scale down becomes lower after transfer, and costs go from monthly fee to a transfer fee to direct costs. In both, you direct the engineering. — Both models: you direct the engineering. BOT moves ownership, admin and cost from the partner to you at transfer.

When should you choose a managed centre?

You want to focus your leadership on engineering, not local HR and compliance
Team size may change significantly over time
You are not ready to commit to a permanent legal presence in the region
You value predictable, all-inclusive costs

When should you choose BOT?

You plan a large, long-term presence in the region
Owning the entity matters for strategy, valuation or regulation
You want to build a global capability centre over time
You have, or will build, the internal capacity to run HR, finance and compliance locally

What does each model cost?

Managed centres typically charge a monthly fee per engineer covering salary, benefits, facilities, IT, management and margin. BOT has similar monthly fees during the Operate phase, then a transfer fee, after which you pay employment and operating costs directly. Compare the total cost over five years, including the cost of running the entity yourself after transfer.

Two-lane grid over years 1 to 5. Managed: one monthly fee across all five years, covering salary, benefits, facilities, IT, management and margin. BOT: a monthly fee during Operate in years 1 to 3, a transfer fee at the end of year 3 (illustrative), then employment costs and the cost of running the entity in years 4 and 5. Each lane ends in a five-year total. — Five-year cost framework: total each model's cost lines over five years, including running the entity after transfer (transfer timing illustrative).

Can you switch between models?

Often, yes. Many organisations start with a managed centre to prove the model, then convert to BOT once the team is established and the business case for ownership is clear. Ensure your contract allows this and defines how a conversion would be priced.

Questions to ask before deciding

Where do we want to be in five years: owning a centre or buying capacity?
How stable is our required team size?
Do we have the appetite to run local HR, payroll and compliance?
Is owning the entity important for IP, regulation or valuation?
What are the conversion and exit terms?

How Crozaint approaches the choice

Crozaint offers both models. In a Managed Operation, Crozaint runs the centre indefinitely while you keep strategic oversight. In Build-Operate-Transfer, Crozaint builds and operates the centre until an agreed milestone, then transfers the entity, team and processes to you.

Either way, engineers report to your engineering leadership, you approve every hire, scaling is flexible and we track retention and on-time SLA compliance (98%) as operating metrics. We help you choose during the 1–2 week Scope step.

Common mistakes to avoid

Choosing BOT without planning post-transfer operations
Choosing managed without clear IP and exit terms
Comparing only monthly rates rather than five-year total cost
No option to convert between models
Deciding before defining team size and roadmap

Conclusion

Managed centres maximise focus and flexibility. BOT maximises long-term ownership. Decide based on your five-year intent, and keep the option to change course.

Frequently Asked Questions

What is the main difference between BOT and a managed engineering centre?

The main difference is long-term ownership. In a managed centre, the partner continues to own and run the centre and employ the engineers. In BOT, ownership of the entity, team and processes transfers to you at an agreed milestone, turning it into your own captive centre.

Which is cheaper: BOT or managed?

In the short term, costs are similar because both involve partner fees. Over the long term, BOT can be cheaper for large, stable teams once you run the centre directly, but you take on administrative costs and risk. Managed centres offer predictable, all-inclusive costs and more flexibility.

Can we convert a managed centre to BOT later?

With many partners, yes. Starting managed lets you validate the model and team before committing to ownership. Ensure your contract includes a conversion option with defined pricing and transfer terms, so the switch is straightforward if you decide to proceed.

Do engineers report to us in a managed centre?

They should. In a well-structured managed centre, engineers take direction from your engineering leadership, work in your processes and tools, and are treated as part of your team. The partner handles employment, HR and operations. At Crozaint, engineers report to your engineering leadership.

How long does a BOT transfer take?

The transfer itself usually takes a few months of planning and execution, covering legal, HR, contracts, assets and systems. It typically happens after two to five years of operation, depending on the milestone agreed in the contract and the client's readiness.
