One PDF, one price, no marketplace: the buyer transfers the money, the seller eyeballs the payment slip and approves them into a Facebook group where the file lives — about ฿1.2M of sales later, that is still the entire checkout.
฿990 per copy · the delivery group holds "about 1,300-plus people"
He built a fully automatic checkout once and ripped it out — "it was quite cumbersome and there are fees to pay." Now the buyer transfers the money, he checks the payment slip by hand, and approves them into the Facebook group where the PDF sits.

The whole business is one PDF. Sian Ped writes an eBook in Canva, sells it at ฿990, and delivers it by approving the buyer into a Facebook group where the file is uploaded. At the time of recording that group held "about 1,300-plus people" and cumulative sales were "about 1.2 million-plus" baht. He calls it semi-passive rather than passive: some buyers message the Facebook Page or the LINE account on their own, and the rest come from ads he pays for. The decision worth studying is the one he reversed. He had built a fully automatic system and took it back out, because "it was quite cumbersome and there are fees to pay." So the money flow is manual on purpose — the customer transfers, sends the payment slip, he checks the slip and approves them into the group. Only the conversation is automated, through the built-in auto-reply that LINE and Facebook already give him. He is just as direct about why he sells this way at all. In Thailand, he says, eBooks are usually sold through marketplaces, and a marketplace takes a commission and a fee; selling direct, "we do it ourselves and sell it ourselves," and he pays neither. His summary of the economics: "Our cost happens only once — creating the PDF. After that we sell it again and again." One more signal he mentions almost in passing. Publishers started contacting him, offering to turn the eBook into a printed book for nationwide distribution. He has not accepted — he says the content is too long for a physical edition — but he keeps the offers as proof that a file which sells is also a calling card. The video itself is the opening lesson of a paid course teaching this method, which is worth knowing when you read his numbers.
Two doors feed the same business: people who message the Facebook Page or the LINE account, and people who arrive from ads he runs on Facebook and TikTok. He is explicit that the ads exist because content skill is not optional in this model — if you are not good at content, you pay for reach instead.

Data credibility: Self-reported by the seller in the opening lesson of a paid course teaching this exact method, so the incentive to present the best version of the numbers is direct and should be priced in. Stated: ฿990 per copy, "about 1.2 million-plus" in cumulative sales, and a delivery group with "about 1,300-plus people" in it, which he shows on screen. Not verified: no bank statement, platform export, dashboard or third-party figure appears; no timeframe is attached to the cumulative total; and no profit, ad-spend or unit-economics figure is given, so margin is inferred from his description of the cost structure rather than stated. The only cross-check available is internal — roughly 1,300 members at ฿990 is about ฿1.29M, consistent with a claimed total "1.2 million-plus". All figures are Thai baht; the transcript offers no exchange rate, so no USD conversion is made anywhere in this entry. The tool list (Canva Pro, Claude, ChatGPT, Gamma.app) and the manual payment-slip workflow are described first-hand.
The first sale in this model is a bank transfer, not a checkout. The buyer moves ฿990, screenshots the payment slip, sends it over LINE or Messenger; he reads the slip, approves the account into the Facebook group, and the buyer downloads the PDF that is already sitting there.
The group is the compounding asset, not the file. Every buyer ends up in the same room — about 1,300 of them — and that room can be sold to again: a second edition, a follow-on product, a service.
He warns the buyer of his own course not to expect passive income, and that warning is the honest description of the quiet period. A PDF that nobody has seen produces nothing, and the silence feels identical whether the product is wrong or the traffic is simply too thin to judge.
