Sian Ped (เซียนเป็ด) — the ฿990 eBook sold and delivered inside one Facebook group

01The full story

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.
