Should You Train Managers In-House or Hire a Training Company?

At some point, every growing company in Vietnam has this conversation. Managers need development. Someone proposes hiring a training company. Someone else points out that your senior people already know the business better than any outsider, so why not train internally?

Both instincts are sound. Internal trainers know your context; external trainers know their craft. The wrong answer is expensive either way: an internal program that quietly never happens, or an external program that teaches generic content your managers cannot use.

Here is the short answer: train in-house when the content is your business (products, systems, processes) and you can genuinely resource it; hire a training company when the content is professional skills (leadership, communication, sales) or when internal delivery keeps sliding down the priority list. Many companies get the best economics from a hybrid: external design and train-the-trainer, internal delivery at scale.

Let's look at what each option really requires, what each really costs, and which builds capability faster.

Why Do Companies Consider In-House Training?

Companies consider in-house training for three reasons: it looks cheaper, it uses people who already understand the business, and it keeps knowledge inside the company. All three are real advantages in the right conditions, which is why internal training dominates one category of content and consistently underdelivers in another.

The pattern is well documented. World Bank research on Vietnam's workforce found that many Vietnamese firms provide training to their workers, but most of it is internal on-the-job training, while external training reaches comparatively few firms and employees. Internal capability-building is the default; the question is whether it is a strategy or just the path of least resistance.

The distinction that decides it is content type. Nobody outside your company can teach your ERP system, your quality process, or your product line better than your own experts. But leadership, communication, coaching skills, and sales technique are professions in themselves, and "knows the subject" is not the same as "can build the skill in others."

So before comparing costs, it is worth being precise about what in-house training actually demands.

What Does In-House Training Actually Require?

A real in-house training capability requires four things most companies underestimate: someone with actual instructional design and facilitation skill, protected time carved out of that person's day job, developed materials rather than borrowed slide decks, and an internal mandate strong enough that training survives contact with a busy quarter.

The Skill Requirement

Facilitation is a craft. Managing a room of 20 peers, running practice safely, giving feedback that lands, and adapting when the plan meets reality are trained skills. A subject expert without them typically produces a lecture, and lectures do not change behaviour.

The Time Requirement

Designing one good workshop day commonly takes five to ten days of work: needs analysis, structure, exercises, materials, piloting, revision. When that work is assigned to a manager with a full-time role, it competes with revenue and loses. This is the quiet failure mode of most internal training plans: not bad delivery, but no delivery.

The Materials Requirement

Handbooks, exercises, case studies, and facilitator guides are what make training repeatable beyond its original creator. Without them, the "program" is one person's slides, and it leaves when they do.

The Authority Requirement

Internal trainers also inherit internal politics. It is harder for a peer to challenge a senior manager's behaviour in a workshop than for an outside professional whose role licenses exactly that.

None of this makes in-house training wrong. It makes it a real investment, which is the honest basis for comparing it with hiring outside.

What Does a Training Company Offer Beyond Content?

A professional training company supplies four things that are expensive to replicate internally: designed programs refined across many organizations, professional facilitators whose full-time craft is skill-building, an outsider's licence to challenge senior people, and guaranteed delivery, because a contracted program actually happens.

That last point is undervalued in most comparisons. The most common outcome of "we'll do it internally" is not a worse program; it is no program, twelve months later. A signed schedule with an external provider converts intention into dates.

Pattern exposure matters too. A trainer who has taught feedback skills in banks, factories, and tech companies has seen where managers get stuck and which exercises unstick them. That pattern library is precisely what a first-time internal trainer lacks, however well they know your business.

In Vietnam, two more factors weigh in. Bilingual delivery: professional providers can run the same program in Vietnamese and English to a mixed management team, which few internal experts can. And scarcity: with only 28.3% of Vietnam's labour force holding formal training qualifications (General Statistics Office, 2024), experienced facilitators are rare enough that most companies simply do not have one idle on staff.

The fair criticisms of external training are real as well: generic content, no context, and disappearing after the invoice. Which is why how you buy matters as much as whether you buy.

Cost Comparison: In-House vs External Training in Vietnam

External training in Vietnam costs roughly 40 to 60 million VND for a custom-designed workshop day, or about 2 to 3 million VND per participant. In-house training swaps that fee for internal time: typically five to ten days of design work plus delivery days, all paid in the salary of someone whose day job is waiting.

A simple model for one workshop, 20 participants:

Cost element	External provider	In-house
Design and materials	Included in fee (40–60M VND)	5–10 days of internal salary time
Delivery	Included	1 day internal salary + prep
Participant salary time	Same for both (approx. 20 person-days)	Same for both
Quality risk	Low (contracted, refereed by track record)	Depends entirely on internal skill
Delivery risk	Low (scheduled, contracted)	High (competes with day jobs)
Repeatability	Buy again, or license materials	High, once materials exist

The crossover point is volume. For one or two workshops a year, external is almost always cheaper once internal time is honestly costed. For the same course delivered many times (onboarding cohorts, a large sales force, multi-site rollouts), in-house delivery wins decisively, if the design is good.

Which points directly at the hybrid.

The Hybrid: External Design, Internal Delivery

Train-the-trainer (TTT) models buy the expensive part once and repeat the cheap part internally. A provider designs the program, delivers a pilot, then trains and certifies your internal trainers to run it. In the Vietnam market, TTT programs typically add 40 to 100 million VND to a design engagement, after which each internal delivery costs only salary time. For any course you expect to run five or more times, this is usually the best economics available.

Which Option Builds Capability Faster?

External training builds capability faster in the first year; in-house delivery scales it cheaper in the years after. If your managers need to lead differently this year, a contracted external program with reinforcement gets there fastest. If you are building a training system for hundreds of employees over several years, invest externally in design and TTT, then run delivery internally.

The decision in four questions:

1. Is the content your business or a profession? Your systems and products: in-house. Leadership, communication, sales, coaching: external or hybrid.

2. How many times will this course run? Once or twice: external. Five or more: hybrid with TTT.

3. Do you honestly have a skilled, available internal trainer? If the answer involves the word "could," you do not.

4. Has this training already been postponed internally? Then the real comparison is external training versus no training, and that one is not close.

   
   

How MDT Works With In-House Teams

MDT Training sits deliberately on both sides of this decision. MDT is a Canadian-owned training and consulting firm in Ho Chi Minh City that has trained 41,000+ employees across 100+ organizations in Vietnam and Southeast Asia, including HSBC, Prudential, Siemens, Sanofi, and Lotte.

Alongside direct delivery, MDT designs programs for internal rollout: full curriculum design with participant handbooks and facilitator guides, pilot delivery your trainers observe, then train-the-trainer workshops that assess and certify your internal team to deliver the content, with the designed materials licensed for your future use. Engagements start with the Talent Clarity Framework (Diagnose, Develop, Scale), so the build-or-buy recommendation is based on your assessed gaps and delivery volume, not on what is easiest to sell.

Sometimes that recommendation is that you should deliver internally. We will tell you when it is.

FAQs

Is in-house training cheaper than hiring a training company?

Only at volume. For one or two workshops a year, external providers are usually cheaper once internal design and delivery time is honestly costed at salary rates. In-house delivery wins when the same course runs five or more times, ideally with externally designed materials.

What is train-the-trainer (TTT)?

Train-the-trainer is a hybrid model where a provider designs a program, delivers a pilot, then trains and certifies your internal staff to deliver it. You pay for design and certification once, then repeat deliveries internally at salary cost only.

When should training be done in-house?

Train in-house when the content is specific to your business, such as products, systems, and internal processes, when the same course will run many times, and when you have a genuinely skilled and available internal facilitator with protected time and ready materials.

When should a company hire an external training provider?

Hire externally for professional skills such as leadership, communication, coaching, and sales, for senior audiences who respond better to an outside expert, when speed matters, or when internal training plans have already been postponed more than once.

What should you look for in a training company in Vietnam?

Look for a verifiable client list, trainers with recognized certifications, bilingual English and Vietnamese delivery, customized rather than off-the-shelf content, a diagnostic phase before design, and a reporting package that measures results after delivery, not just satisfaction scores.

Can internal subject experts become good trainers?

Yes, with investment. Subject expertise supplies credibility, but facilitation, exercise design, and feedback are separate trained skills. A train-the-trainer program plus well-built facilitator guides typically turns a strong expert into a competent internal trainer within a few supervised deliveries.

How much does a train-the-trainer program cost in Vietnam?

In the Vietnam market, train-the-trainer typically adds roughly 40 to 100 million VND to a program design engagement, covering trainer workshops, assessment, and certification. After that, each internal delivery costs only staff time, which is why TTT pays off at volume.

Do external trainers understand our industry?

Good ones close the gap with a diagnostic phase: stakeholder interviews, assessments, and content built on your real scenarios. Ask any provider how they customize; if the answer is "we adjust the examples," the content is off-the-shelf regardless of the label.

Why do internal training programs so often fail to happen?

Because design and delivery time is unprotected. Internal trainers have day jobs, and training loses every scheduling conflict with revenue. The most common result of an in-house plan is not poor training but postponed training, which is why contracted external dates so often win by default.
