Many people think that AI subscription recharge is just selling an account to make a profit margin.

Actually, once you do it for real, you'll find that customers don't just want to buy an account.
They don't know how to buy, can't register, don't know how to pay, don't understand the differences between Plus, Team, Pro, Max, API, and also don't know which plan suits them best.
Some people buy but don't know how to use it, so this business is essentially a service.
Help them choose, help them set up, help them configure, and by the way, tell them how to use it, renew later, and be available if problems arise.
The money customers pay isn't just for a subscription; more often, it's for saving trouble.
They don't need to study a bunch of tutorials, worry about buying the wrong thing, or ask around if something goes wrong.
Individual users who want to write copy, create images, or organize data, you tell them how to use it; small teams wanting a few people to use it together, you help arrange the Team; developers need APIs, you handle interface limits and call issues—this is much more valuable than just reselling.
Now, there are more and more AI tools, and ordinary people simply can't tell which one suits them, nor do they have time to research every day.
The more these things exist, the more they need someone in the middle to help save them trouble.
So, AI subscription services are not shameful, nor are they just simple reselling.
It's a very practical small business; if done well, it could become a big cake.
Customers don't care how powerful you are; what they care about is that when they have a problem, you can help solve it.
As long as the price isn't unreasonable, no one will fuss over a few dozen yuan.
Really, the time, energy, and cost are more expensive.
