Managing payouts to customers for product they sell back

I was wondering if there was a solution for managing payouts to customers who sell us product in the POS. We’re a record store and we have people bringing their records in to sell back for cash. We haven’t found a way to document this in the POS, so at the end of the day the drawer is always short and we just document it by writing the payouts on a post-it. Our accountant obviously doesn’t love this idea.

I went back and forth with support and they couldn’t help. Any support or App Store searches just bring up results about payouts from Shopify. Basically, we need something that could log payouts or something that can enable creation of a product with a negative price. It seems like something like this should exist. Any ideas? Thanks!

I need your assistance please I am facing the same issue.

I don’t think it’s possible to make a negative price anywhere in Shopify.
