What this case covers
The author is a big-tech programmer who has done AI top-ups as a side hustle for more than two months, first connecting to ready-made supply to sell, and building a self-built redemption site two weeks ago. The article compares the two routes of technical self-building and beginner shop-opening in terms of preparation, cost, after-sales, and customer acquisition.
Questions it answers
- Who is each route suited to: a self-built redemption site or opening a shop with ready-made supply?
- What conditions does the author value most when screening card platforms?
- How are the costs of one Plus order broken down?
- Why does sales collection still use a third-party shop?
- What after-sales rules should be written clearly in advance?
Our observations
- The core difference between self-building and connecting to supply is which links you take on, not which is more advanced.
- Card codes are equivalent to cash; you must control the code-issuing and redemption process yourself.
- Funds turnover is tied up in the buying-U step; reserve working capital and control the size of each order.
From the author
Having technical ability does not mean you have to build every system yourself. I built a redemption site myself, but sales and collection still use a third-party shop.
