Facebook Marketplace Seller Cost Checklist
Use this checklist of Facebook Marketplace seller costs to avoid underpricing items or accepting weak offers after item cost, delivery cost, shipping cost, packaging, negotiation discounts, repairs, pickup friction, and refund risk.
What costs should Facebook Marketplace sellers track?
Facebook Marketplace sellers should track every cost that affects whether a sale actually produces profit. Some costs happen on every order, such as item cost, packaging, delivery, shipping, or platform fees when applicable. Other costs happen less often, such as repairs, refunds, no-shows, storage pressure, and relisting time.
The most common mistake is judging profit from the sale price alone. A listing can look healthy until buyer negotiation, delivery time, fuel, repair supplies, packaging, pickup delays, stale inventory, and refund risk are included.
