How is seller standard calculated?

[Haidukken]

I know the overall thing, but I have a specific question regarding how exactly is it calculated when it comes to transactions.
My question:
If I have one product for sale, with a quantity of 20, and I sell 1, then it is clearly 1 item, 1 transaction. ONE point to my sales when it comes to seller standard.
If I then sell 11 of them to ONE customer, does that count as 1 single transaction, or 11 transactions?
Meaning, do I get 1 point towards my seller standard total transactions or will I get the 11, because I sold 11 items?

Thanks guize.

If someone buys 11 of your items that's considered 1 transaction...Not 11.

As always, much appreciated.

BUT,

What if one person purchases 25 different items, but I will combine the invoices to one?
Is that still one transaction towards my sellers rating?
