Hi there,
The payments are normally issued before the 20th (not necessarily exactly on 20th).
The other part, sadly, is that paysera payout fees have been increased from 2017-07-12 (you can find the information about it by dragging your mouse on the payout fee sum in your payments information). We're currently working on integrations that will help lower these payout fees.
Regards,
