Flyp

As a Pro Seller, you have the freedom to set your commission for each lot. The commission you set must be all-inclusive, meaning that it must account for and include in it any fees charged by marketplaces you might use (except shipping fees). The split applies to the actual selling price and not to the net earnings (shipping is excluded of course). The client expects to earn the selling price of an item minus the commission you set. 
 
Example:
Your commission: 50%
Item sells for:         $100
Poshmark fees:     20% ($20)
You net:                 30% ($30)

If you offered Free Shipping on a sale, then deduct the cost of shipping from the sold price, then re-apply the above with the adjusted sold price.

Commission competitiveness scale:​
60% Less competitive 
50% Standard ✓
40% Very competitive

Keep in mind: Flyp is 100% free for you as a Pro Seller, but a 10% service fee applies to your clients/consignors in addition to a shipping fee of $0.99 per item (with a $9 minimum per lot paid for by the client). Keep that in mind when setting your commission.
