ShopMy generates a recommended flat fee for each creator to help you make informed decisions quickly. The recommendation is driven primarily by the creator's audience size and reach, and also factors in the scope of what you're asking for. The more deliverables an Opportunity requires, the higher the recommended fee, along with relevant performance signals.
Recommended fees are a starting point, not a fixed rate. You can adjust a fee up or down before sending an Opportunity to a creator.
