Hey there,

I want to tell you a story that almost no one tells publicly.

It's a story about a brand that did everything "right"—and still nearly broke themselves trying to diversify their supply chain.

This isn't a case study where I swoop in with a framework and everything works perfectly. This is what actually happens when a real brand, with real constraints and real pressure, tries to move production from China to Vietnam.

It took 14 months instead of 6. It cost $93,000 more than budgeted. And for the first year, they were underwater.

But here's the thing: it worked. Eventually. And the lessons from their journey are worth more than any "5 Steps to Diversify Your Supply Chain" article you'll find online.

Let me walk you through exactly what happened.

The brand—let's call them Brand V—was doing $6.2 million in annual revenue. Apparel and accessories. 100% of their production was in China, spread across three factories they'd worked with for years.

In early 2023, they made a decision that a lot of brands were making: diversify. Move some production out of China. Reduce risk. The tariff situation was uncertain, their investors were nervous, and frankly, putting all your eggs in one basket had started to feel reckless.

Their goal was modest: move 30% of production to Vietnam. Not everything. Just enough to have a real alternative if something went wrong with their China supply chain.

They talked to consultants. They read the articles. They joined the Slack groups. Everyone said the same thing: Vietnam is great. Quality is good. Costs are competitive. Six months and you'll be up and running.

Six months sounded reasonable. They had a good team. They'd done hard things before.

So they committed. Told their board six months. Told their team six months. Built their inventory plan around having Vietnam production online in six months.

That's when the education began.

Finding Vietnamese suppliers wasn't hard. Within six weeks, they had conversations going with eight factories. Trade shows, Alibaba, referrals from other brands—the pipeline filled up quickly.

They narrowed it down to three promising candidates. Scheduled video calls. Saw the facilities. Everyone seemed professional and eager for the business.

This part felt good. They were ahead of schedule.

What they didn't realize: finding suppliers is the easy part. Everything that comes after is where timelines die.

They sent specs to their top two factories. Detailed specs—or so they thought. The same specs they'd been using with their China suppliers for years.

First samples came back. Wrong. Not subtly wrong. Obviously wrong. Thread colors were off. Stitching patterns didn't match. One factory used completely different hardware than specified.

"No problem," both factories said. "We'll fix it. Send new samples in two weeks."

Second samples came back. Better, but still not right. The fit was off on one style. The fabric weight was slightly different—not enough to reject outright, but enough to notice.

Third samples. Getting closer. But now they'd discovered that one factory couldn't actually do the specialty stitching on their best-selling product. A capability they'd claimed in the initial calls.

Fourth samples.

By this point, three months had passed on sampling alone. They'd spent $12,000 on samples and shipping. And they still didn't have a single product they were confident enough to put into production.

What went wrong: Their specs were detailed by China standards. They'd been working with their Chinese factories for years. Those factories knew what they wanted, even when the specs were ambiguous. A new factory doesn't have that context. Every assumption gets tested. Every ambiguity gets interpreted differently.

The spec documents that took them 3 pages in China needed to be 15 pages for Vietnam. Photos of every detail. Measurements for things they'd never measured before. Reference samples sent alongside written specs.

They learned this the hard way. By month 5, they'd developed new spec templates that were 10x more detailed than what they'd been using. Those templates are still in use today.

By month 6—their original target for being "up and running"—they'd finally approved samples from one factory and placed their first production order. 2,000 units of a relatively simple product. A test run before scaling up.

The units arrived at month 8.

Defect rate: 12%.

That's 240 units they couldn't sell. At their product cost, that was $28,000 in unsellable inventory.

The defects weren't consistent—that was the maddening part. Some units had stitching issues. Others had hardware that was slightly misaligned. A few had small stains that hadn't been caught in QC.

When they pushed back on the factory, communication became a problem. Time zone differences meant emails sent at 4pm their time got responses at 3am. Back-and-forth that would have taken a day with their China suppliers took a week.

Language barriers they hadn't noticed during sales conversations became obvious when discussing technical quality issues. The factory's English-speaking sales rep didn't have the vocabulary to translate detailed quality complaints to the production floor.

They had to bring in a translator for calls. That helped, but added another layer of complexity.

What went wrong: They'd underestimated how much their relationship with their China factories was worth. Years of working together meant shared understanding. Quick resolution when issues came up. Trust that let them skip steps. None of that existed with the new factory. They were starting from zero, and they'd priced the transition as if they were starting from 50.

At this point, they had a choice. Abandon the Vietnam effort and write off the investment. Or dig in and figure out what was actually required to make it work.

They chose to dig in. Here's what they did differently:

Hired a local agent. $2,500/month for someone on the ground in Vietnam who could visit the factory, attend production runs, and serve as a cultural and language bridge. This was their single best decision. The agent caught issues in real-time that would have taken weeks to surface through email.

Kept China active. They'd originally planned to shift production as Vietnam ramped up. Instead, they ran both in parallel. China remained their primary source while Vietnam was treated as a training ground. This cost more in the short term but protected them from stockouts.

Over-communicated internally. They started weekly cross-functional syncs specifically about the Vietnam transition. Marketing knew what was realistic. Finance knew the true costs. No one was operating on the original six-month fantasy anymore.

Started with simple products. They stopped trying to move their complex styles to Vietnam. Instead, they focused on their simplest products—the ones with the least room for error. Master the basics before attempting the hard stuff.

10x detail on everything. New spec documents. Video walkthroughs of exactly what they wanted. Reference samples sent with every order. Checklists for the factory. Checklists for their agent. Nothing left to interpretation.

By month 12, the Vietnam production started to feel real.

Defect rates dropped to 4%—still higher than their China factories, but acceptable. Communication improved as relationships developed. The agent knew what to look for. The factory understood their standards.

By month 14, they were confidently producing 30% of their volume in Vietnam. The original goal. Eight months late.

Let's talk numbers. Because this is where the "diversification is great" narrative usually gets vague.

Year 1 Total Additional Costs:

Total unexpected costs: $93,000

Against their planned transition budget of $20,000.

Year 1 Savings from Vietnam Production: $62,000

Net Year 1 Impact: -$31,000

They lost money in Year 1. That's the reality.

Year 2:

Net Year 2 Impact: +$50,000

Year 2, they turned profitable on the transition.

Year 3 and Beyond:

Net Annual Impact: +$62,000

Payback period on the transition: 18 months.

By the end of Year 2, they'd recovered their investment. Year 3 onwards, they're saving over $60,000 annually—and they have supply chain diversification that protects them from single-country risk.

Was it worth it? Yes. But not in the timeframe or budget they'd originally planned.

I spent hours debriefing with this brand's ops lead. Here's what they said they'd do differently if they could start over:

1. Say 12-18 months, not 6.

The six-month timeline was based on optimism and other people's case studies. It created pressure that led to bad decisions—rushing approvals, accepting samples that weren't quite right, placing production orders before they were ready.

If they'd told their board "18 months," they would have had space to do it properly. The outcome would have been better and probably faster, because they wouldn't have wasted time on mistakes caused by rushing.

2. Budget $75K+ for the transition.

They budgeted $20K. They spent $93K in unplanned costs. If they'd budgeted $75K from the start, they would have made different decisions. They would have hired the agent earlier. They would have built in contingency for samples. They wouldn't have felt underwater the entire time.

Underfunding a supply chain transition doesn't make it cheaper. It makes it more expensive, because you pay for mistakes instead of prevention.

3. 10x more detail in specs.

This can't be overstated. The spec documents that work with factories who know you don't work with factories who don't. Every measurement. Every color code. Every material specification. Photos of what "right" looks like and photos of what "wrong" looks like.

They now treat spec development as a distinct phase of any new supplier relationship. It takes time. It's worth it.

4. Hire the agent before the first sample.

They hired their agent at month 9, after the first production disaster. If they'd hired the agent at month 1, they would have caught the sampling issues earlier. The agent would have visited the factory before they placed the first production order. The $28K in defective inventory probably wouldn't have happened.

$2,500/month seems expensive until you compare it to the cost of mistakes they could have prevented.

5. Don't cut over. Run parallel.

Their original plan was to shift production from China to Vietnam as Vietnam ramped up. Thank God they didn't follow that plan. Keeping China running gave them flexibility when Vietnam stumbled.

Run parallel until the new source has proven itself with at least three successful production runs. Then start shifting volume. Not before.

Diversification works.

This brand now has 30% of their production in Vietnam. They have relationships with factories that understand their standards. They have systems that will make adding future suppliers faster. They've reduced their single-country risk.

But it took 14 months instead of 6. It cost $93K more than planned. And for the first year, they were losing money on the transition.

That's not a failure story. That's a reality story.

If you're thinking about diversifying your supply chain—and you probably should be—go in with open eyes:

The brands that fail at diversification aren't the ones who encounter problems. Every brand encounters problems. The ones who fail are the ones who planned for a smooth transition and had no margin for reality.

Reality always shows up.

If you're considering a supply chain diversification:

1. Audit your current specs. Pick your most complex product. Could a factory who's never worked with you produce it correctly from your spec document alone? If the answer is "probably not," you have work to do before you start talking to new suppliers.

2. Research local agents. For any country you're considering, start identifying sourcing agents or QC partners now. Ask other brands for recommendations. Interview at least three. You'll want this relationship in place before you need it.

3. Pressure-test your timeline. Whatever timeline you're planning, double it. Then ask yourself: does this still make sense? If the business case only works with an optimistic timeline, the business case doesn't actually work.

I go deeper on the real economics of China + 1 in this week’s YouTube video—breaking down the exact cost model behind those $34K losses and $380K wins, including how to calculate your true landed cost, transition budget, and whether diversification actually pays off for your volume (hint: most founders skip the math that matters).

Until next time,

P.S. I know this newsletter was heavy on the "it's harder than you think" message. That's intentional. Not because I want to discourage you from diversifying—the opposite, actually. I want you to succeed. And the brands that succeed are the ones who go in with realistic expectations and adequate resources. The ones who fail are the ones who were sold a six-month fantasy and didn't have the margin to handle reality. Don't be that brand.
