I run a solo China sourcing agency. Here's a case from this week — and how it becomes content across ten platforms.

Quick context: I'm the founder of Canton Qwen, a buyer-side China sourcing agent and factory check firm based in Guangzhou. Solo operator. Overseas buyers only. No supplier commissions.

The business is small, so content marketing has to work. Every real client interaction that produces a useful story becomes a content asset for every channel I use. Same facts, adapted to each platform's format.

Here's a case that came in a few days ago — and I'm sharing both the story itself and the process, in case either is useful.

The case

A European buyer came to me for a supplier check. Alibaba supplier for car vacuums, sample looked good, ready to place 500 units at USD 8.30–8.50 per unit; DDP freight, duties, and related delivery charges were quoted separately. He asked one question:

"Can you check if they're actually the manufacturer?"

Two hours of public-record checking later:

• Three supplier-presented affiliated companies under the same legal representative — two Shanghai trading entities, one Ningbo manufacturing-scope entity
• An ISO 9001 certificate for the Ningbo company at an address the company had already moved out of
• Supplier refused to send a video of the production line with the buyer's name on paper
• A separate fourth company tied to the Cixi address the supplier gave for inspection — never disclosed as related. Similar product on 1688 (the Chinese domestic sourcing platform) at ~RMB 33 per unit versus a USD 8.30–8.50 per-unit export quote

I didn't call it a scam. I couldn't prove that from public records. But I could tell the buyer: "the supplier looks legit" and "the supplier controls your order" are two different questions.

Advice: run the 500 units as a controlled trial, lock the PI, inspect the goods before final payment, arrange a factory check at the real Cixi production site if you want to scale.

The content process

Same case, ten channels. All the numbers stay identical across every version (500 units, USD 8.30–8.50 per unit, RMB 33 per unit on 1688, ~2 hours of remote check, four-address / three-affiliated-plus-one-separate-fourth-company finding). This keeps the story internally coherent — no version accidentally contradicts another when a reader crosses platforms.

Rough format map:

• LinkedIn (personal + company page): 400–500 word case posts
• X thread: 14 tweets, punchy
• Facebook (personal + page): shorter narrative
• Medium: 1,500-word essay
• Substack: newsletter framing
• YouTube: talking-head script with chapter marks (~7 min)
• Pinterest: 5 visual pins, each with the same story hook
• Indie Hackers: this post, process + case

The base narrative was written from raw case notes as part of the process. Once the base exists, each platform adaptation is a rewrite pass tuned to that platform's format — no new information, just different shape.

Underlying pattern: I don't write "content" from scratch. I write case notes from real client work. Then a content pass shapes each case into platform-appropriate formats. The case notes are the leverage. The platform adaptations are near-mechanical once the notes exist.

Would love to hear from any solo founders running service businesses — how are you handling the content pipeline? What's your ratio of "originate content" vs. "shape client work into content"?
