Why Seller Central Lies to You
Seller Central's "net proceeds" number excludes: Cost of Goods, inbound shipping, prep fees, storage fees, return processing, and advertising spend. Real profit is often 40–60% lower than the number Amazon shows.
Setting Up Your P&L Dashboard
- Go to P&L Dashboard in niche.ltd
- For each SKU, enter your Cost of Goods Sold (COGS) including manufacturing + shipping to warehouse
- Add inbound FBA shipping cost per unit
- Set advertising spend (pulled automatically if SP-API connected)
- niche.ltd automatically pulls FBA fulfillment fees, referral fees, and storage costs from your Seller Central data
Understanding the Dashboard
Gross Revenue — Total sales before any deductions
Referral Fee — Amazon's selling commission (8–20% depending on category)
FBA Fees — Pick, pack, ship, and storage
COGS — Your cost per unit × units sold
Advertising — PPC spend for that SKU
Net Profit — What you actually keep
