The field "MSRP" on Modalyst refers to the retail price of the product. This is what you are selling the item for on your own site, for example. We encourage you to keep all your retail prices consistent across all sales channels.
When a dropshipping order is placed, the Retailer will pay you 60% of the MSRP. That is uniform / standard across all products and Suppliers in the Dropshipping portal.
Please note the Retailer will pay you 60% of the MSRP regardless of what they sell the product for. They are allowed to control their margins but it will not effect your commission.
