Adjusting your revenue split in your settings tab will only affect partnerships moving forward, and will not affect existing partnerships.
To update your revenue split with existing partners, you will need to come to a new agreement with your retail partner through email. You can find the appropriate contact method through the Partners tab.
Please forward the agreement to Carro support via Intercom or support@getcarro.com for our team to verify the agreement and process the request.
Note: You do not need your partner's approval if you're increasing their revenue split (E.g. I would like to offer my retailer 35% instead of the current 25%).
