Hi .. it's more than 1 year i use wirestock only for Getty/iStock and some other small agencies ...
yes i had the same problem ... weeks without notification of sales ... i contacted the support various times ... The average customer service is sufficient, sometimes they answer not satisfactorily but it depends on the operator, except for a few operators who gave me clear answers.

Essentially, they update the sales when they receive the sales report from the various agencies... and you can't be sure if they record all the sales...

in any case, I average $100 a month and the payments have always been on time... I'll tell you what Ike from the staff answered me...

Hi Davide,
 
I hope my email finds you well.
 
Just wanted to share an update about your Wirestock sales. As I can see, there are sales added for the past month, even though the number of sales is a bit lower than before.
 
There is nuance there that I'd like to explain. Not all marketplace share their sales reports monthly, so some of the sales get added later. This creates a little inconsistency, so you get way more for one month, and then not much for another. Wirestock adds any earnings the moment we receive them.
