Me too, despite everything I read on the Facebook forum. When I launched my professional account in 2021, I had no idea what to do, so I contacted URSSAF, who redirected me to the tax office, who confirmed in black and white that shipping costs were not to be declared. If I ever get audited, I’ll bring out the email exchanges and that’s that 
There’s also this part in the Vinted T&Cs which I find quite clear
The implementation of DAC7 is recent. The first checks, if any, will take place in 2026. The tax authorities will then go back as far as 2023 (correct me if I’m wrong).
From the controller’s point of view, there is no interest in checking if one cannot go back as far as possible, and collect a multi-year adjustment in one go. Therefore, DAC7 audits will begin soon, and we will only have testimonials next year.
In micro and I declare the collection date on the bank account.
and then also see the amounts involved. They won’t commit resources if there’s a few euros difference. Especially for micro-businesses with very simplified accounting rules where they know it will be a mess to trace everything. Of course, if platforms send thousands of € in monthly sales and nothing is declared, eventually it will raise a flag.
Anyway, between cash-in-hand sales or sales that go through outside of DAC7 (because few sales on a small platform), I always declare more than the amounts sent by the platforms.
I will change my procedure and switch to the purchase date instead of the payment date.
I sell an F item for 10 euros on October 3rd.
On October 10th, there was a return and I refunded the €10.
My question is: In accounting, do I record the refund on the date of the refund, October 10th, or do I have to go back to the item’s purchase date, thus modifying the daily payment record of October 3rd?
Thank you
Good evening everyone!
If you want to save time in creating your invoices and managing your accounting for your business, I advise you to take a look at the Clemz.app dashboard if you are already subscribed. 
Good evening Lucille!
I have recorded my data for invoicing. Until now, I was editing the invoices but not sending them to the clients. I was archiving them. Is it mandatory to send them? With the clemz CRM, will I be able to retrieve the invoices? Thank you!
Hello,
According to the pro guide, no, the invoice does not seem to be mandatory if you use the OSS system, otherwise yes, it is mandatory:
Guide VINTED POUR LES VENDEURS PROFESSIONNELS | Vinted
In your tracking, you have the option to obtain the invoice. Contact us by email if needed 
if the amount is greater than €25, it is mandatory to send it.
It seems to me that the €25 is for the service, in sales it is mandatory for remote sales.
