The mistakes foreign brands make in Vietnam, and what they cost

Most lists of mistakes in Vietnam are about manners and words: a gesture, a colour, a slogan that translates badly. Those mistakes are real, and they are cheap. Customers point them out within days, and a team can fix them within a week.

The mistakes that cost foreign brands real money here look different. They are structural, they are made before or during launch, and they look fine in the monthly report for two or three quarters. By the time they surface, a large share of the first-year budget has been spent on a decision taken from the wrong number, and some of them cannot be reversed at any price.

This piece sets out eight of them, in the order a brand usually makes them, with when each one tends to become visible, what it costs, and the single number that would have caught it early.

Eight mistakes, and when the bill arrives

The first three remove options. The middle two set the wrong yardstick. The last three misread the results. That grouping matters more than the ranking, because each group is caught by a different person at a different time.

Why the expensive mistakes are the quiet ones

A useful way to put a number on a mistake is to ask two things: how much money is being decided by it each month, and how many months pass before anyone can see it. The product of the two is the exposure. Add whatever it costs to unwind, and you have the bill.

A translation error in a launch video has a small exposure. It affects one asset, it is visible to every viewer, and someone usually mentions it in the comments in the first week. A revenue definition that counts confirmed orders rather than delivered ones has the largest exposure of anything on this list: it decides every channel comparison, every month, and nothing in the advertising dashboards contradicts it. Cash on delivery is common here, and a share of confirmed orders is refused or never collected, so the gap is real and it is not spread evenly across channels.

This is also why these mistakes survive. Nobody in the chain is hiding anything. Each report is accurate for the question it answers. The mistake lives in the question that nobody asked, and Vietnam has a few more of those than most markets because the order, the payment and the delivery are separated by days and often by different companies.

Before launch: mistakes that remove options

The trademark is filed late. Vietnam broadly follows a first-to-file principle: the first party to file a mark here generally gets the right to it, regardless of who used it first elsewhere. Brands that are gaining attention in nearby markets are watched, and filings by people with no connection to the brand are a known problem, followed by an offer to sell the registration back. The filing is a question for an IP lawyer. What marketing needs is the answer before the launch plan depends on the name, because the registration is also a working document: verifying a Zalo business account requires a Vietnamese business registration or a trademark protected in Vietnam, and official brand stores on the marketplaces ask for proof of trademark rights or an authorisation from the owner of the mark.

A partner registers the stores and accounts. It is the fastest way to launch. A distributor or agency opens the marketplace stores, the advertising accounts, the social pages and the Zalo account, in its own name, because it has the local entity and the brand does not yet. Nothing goes wrong for a year. Then the relationship changes, and the brand discovers that ratings, reviews, followers, conversation histories and years of advertising learning belong to whoever registered them. The fix costs one clause at the start: who owns each account, who has administrator access, and what transfers at the end.

Exclusivity is wider than the partner can serve. A first distributor asks for national exclusivity across all channels, and it is often granted because there is no second candidate in the room. If that distributor is strong in supermarkets and weak online, the brand has given away its fastest-growing channel for the length of the term. Exclusivity is better scoped by channel and region, with renewal tied to sell-out targets the partner can actually influence; the detail is in how to choose a distributor in Vietnam.

In the business case: mistakes that set the wrong yardstick

The forecast is a share of a published total. The business case takes a national figure for e-commerce or for the category, assumes a modest share of it, and sizes the budget to match. The trouble is that the total measures a market the brand cannot reach: other price bands, other channels, cities it will not sell in for years. The published figures do not even agree with each other, because they measure different things. When the first-year plan is built this way, sales trail it from the third quarter, and the Vietnam team spends the rest of the year explaining a gap that was in the plan from the start. Building the number from the category upward is set out in sizing the Vietnam market without buying a report.

The price is converted from home, then discounted to fit. The list price starts as the home price at today’s exchange rate, adjusted for duty and margin. It lands above the band the category already has, sales are slow, and the response is a voucher. By the first double-date sale season, buyers have learned that the real price is the discounted one, and the list price has stopped meaning anything. The cost is not only the margin given away on each order. It is that every later price rise has to fight a reference point the brand created itself.

In the first year: mistakes that misread the results

Confirmed orders are counted as sales. Advertising platforms and most order systems count an order when the buyer confirms it. Finance counts it when the money arrives. Between the two sit refusals at the door, buyers who cannot be reached, and returns. If the monthly report uses confirmed orders, the channels that generate the most impulsive orders look cheapest, and budget moves toward them. Those are often the same channels with the highest refusal rate.

Channels are cut on in-platform return. Each platform reports the sales it can see. A social or video channel that sends buyers to search for the brand on a marketplace gets no credit for those sales, so its reported return looks poor next to marketplace search advertising, which collects them. When the budget is cut, the social channel goes first. A month later marketplace sales fall, and the marketplace advertising is blamed. The order system, not any platform dashboard, is what keeps this from happening, which is the subject of marketing measurement for a Vietnam operation.

Tests have no written stop rule. A new channel is tried, results are mixed, and nobody wrote down beforehand what result would mean stop, continue or scale. The test then runs until someone at head office loses patience, which is a decision about patience, not about the channel. Writing the rule takes ten minutes before the first dollar is spent, and it is the only way the result of a test can change anyone’s mind.

A worked example: one year, three quiet mistakes

The figures below are illustrative, invented for the example. A foreign personal care brand enters Vietnam with a first-year media budget of USD 480,000, spent evenly at USD 40,000 a month. Its target is a cost per order of USD 15.

Count the exposure. For seven months, USD 280,000 of spending was judged against a cost per order that was about a fifth too optimistic. For three of those months, a growing share went to the channel that looked cheapest on that number. The budget cut in month nine was made on a plan that had never been reachable, and it landed on the wrong channel because of a reporting convention. None of the people involved made an unreasonable decision with the information in front of them.

The fixes, by contrast, would have cost almost nothing in month one: one column for delivered orders, one bottom-up estimate, one ownership clause.

Catching each one early: the number to watch

Every mistake on the list has a number that exposes it long before the quarterly review does. Most of them can be read from data the brand already has a right to.

The second and sixth rows deserve the most attention, because they are the two a head office can check itself without asking anyone in Vietnam for a favour.

What this list leaves out, on purpose

Three kinds of mistake are missing from the table, and the omission is deliberate.

Cultural and language mistakes are left out because they announce themselves. Translating a campaign word for word, rather than rebuilding the offer for how the category is bought here, is a real error with a real cost, but it shows up in comments, in chat questions and in a weak conversion rate within weeks, and there is usually someone on the team who saw it coming.

Regulatory mistakes in advertising content are left out because they belong to a lawyer, not to a list. Several categories need content approval or carry restrictions, and the penalty lands on the brand. The fix is to ask before the first campaign, not to read a summary.

Choosing the wrong agency is left out because it is usually a consequence of the mistakes above rather than a cause. An agency judged on confirmed orders and in-platform returns will optimise for both, competently. Changing the agency without changing the yardstick tends to reproduce the same year with a different logo on the report.

Where this work stops

MWY does not file trademarks, draft contracts or give legal advice; the trademark and the advertising rules belong with lawyers in Vietnam. MWY also does not run advertising, operate stores or take commission from any agency, distributor or platform, which is what lets us say plainly which number is wrong.

What we do sits on either side of launch. Before entry, Go-to-Market Strategy builds the category estimate, the price band, the channel order and the account and data terms a partner contract should carry, so that the first five rows of the table are settled before money moves. Once the brand is selling, Vietnam Marketing Advisory & Oversight reads the order system against the platform reports every month, keeps the revenue definition fixed, and writes the stop rule before each test, which is where the last three rows are caught.
