One benefit of using PartnerStack is that they handle all partner payouts. Once a month, ParterStack generates a partner commission invoice. As a vendor, you have 7 days to review it, and once the review period ends it is automatically charged to your payment on file and dispersed to your partners.
As a partner, we love that with PartnerStack we get one payout rather than a zillion tiny ones like with other platforms like Cello, for example (total nightmare to deal with as a publisher/content creator).
That said, we do wish that PartnerStack would modify the way they handled payments to creators.
As partners, we have to manually trigger every payout and each one comes with a small fee ($3, $3.50, $3 + $0.50, etc.). We'd much prefer automatic payouts or at least a smoother UX to reduce the constant mental overhead. PartnerStack says they limit automatic payouts for “security reasons” because some partners don’t verify their accounts properly, which can lead to payments going to the wrong PayPal or an old email. But in our eyes, that means the product is being optimized for low performing partners who aren't taking affiliate seriously, instead of the creators and businesses who actually are the top performers.
