In those cases, it does seem to be because the person made a huge amount of sales in a short period of time..I don't plan on having a large amount of sales all at once, or any time soon, but I'm trying to err on the side of caution.
So for now I'll probably keep using Sellfy, but I want to know what other options might be available for selling digital products where the payment goes straight to the marketplace I'm selling through, and then I can request a payment once a month or something like that.
I think Etsy seems to work that way, but I'd prefer something like Sellfy that's more geared to what I'm selling. Also, Etsy charges 20 cents every 4 months per listing, and I want to have a large amount of products.
By the way, I know about Gumroad, but I don't know if it works just like Sellfy where you receive the payment right away or not. Any suggestions?
