Hello, I’m considering switching to Vinted Pro. I’d like to hear from people who are already using the Pro version. Is it worthwhile or a hassle? How many sales per day are needed to be profitable, and what’s the profit margin per sale? … In short, your opinion and perhaps some advice 
Thank you all
Have a good day
The issue isn’t really framed that way. Not being a professional is always more interesting because you don’t pay taxes on your activity.
The problem is that when the practice of buying and reselling becomes habitual, you become a professional according to the law. So if you don’t register, you risk both a tax assessment and legal proceedings by URSSAF for undeclared work.
Since platforms are required to report sales to the tax authorities above a certain threshold, it becomes impossible to commit fraud by selling online.
So the choice you have is either to settle for a very small activity or to turn professional.
Once again, the problem is not posed like that.
The only difference from what you are currently doing is that you will pay 12.3% of your turnover to URSSAF. You sold for €1000, and you will declare it to URSSAF, which will ask you to pay €123.
Since you are already engaged in buying and selling in an non-habitual manner, as an amateur, you can see what it would leave you if you went professional, whether it is profitable or not for you.
