Yes. Firstly, you have to upload a Sales report which reflects your trading activity. Usually, it can be easily downloaded from most platforms. It should reflect:
- sales amount
- tax amount
- countries where products were distributed
Sales report counted as 1 document. Note that you also have to upload all invoices, but they’re not counted towards the quota.
Also if you receive money not directly to your bank account, but through a payment system (Stripe, Paypal for example), you have to upload a Balance statement from the systems. It is also not counted in the quota. Other rules are common as for regular accounting.
