Wondering how eBay compares?

Why eBay margins are hard to track

One of the world’s biggest marketplaces, with fees that add up quietly.

eBay gives sellers access to one of the largest buyer bases anywhere, but the Final Value Fee varies by category, Promoted Listings spend can quietly erode margin on your best-performing items, and Managed Payments processes everything through eBay directly. A sales total on its own doesn’t tell you what a listing actually earned. You have to work backwards through every fee to find out.

Every eBay order is reconstructed from its components: principal and shipping charged to the buyer, so the starting number is the real one, not an estimate. WhatSales then deducts the costs that decide whether an order made money:

  • ✓Final Value Fee pulled from the order at its actual category rate, not a flat percentage.
  • ✓Promoted Listings ad spend, so boosted listings show their true cost.
  • ✓Shipping & postage, including labels you buy yourself.
  • ✓Product cost (COGS) and any per-unit or operational costs you add.
  • ✓Full order P&L, plus product-level economics for every SKU.

The result is an estimated profit and margin you can trust: the figure that reaches your bank, ready to sort, filter and trend across your whole catalogue.

True profit on every eBay order, not a sales total. eBay’s Final Value Fee, Promoted Listings spend and category-specific rates all chip away at the same sale. WhatSales rebuilds each order from its raw parts, then applies the actual costs, to give you profit and margin per order and per SKU.

Sort by margin, filter by product, trend across the quarter: eBay sits in one dashboard with Amazon, Shopify and every other channel you connect, rather than in a fee statement you have to decode by hand.

The Final Value Fee changes by category

A listing that looks profitable can be thinner than it seems.

eBay sets its Final Value Fee per category, so a listing that looks profitable at a glance can be thinner than expected once its actual rate applies. WhatSales applies the real rate to every order.

Electronics
Lower Final Value Fee category.
8%
Collectibles
Mid-range Final Value Fee category.
12.9%
Clothing & Accessories
Higher Final Value Fee category.
13%

Three categories, three fee rates: the same £20 product earns a different margin in each. WhatSales tracks the real rate per order, so nothing gets averaged away.

Everything you need

Everything you need to run eBay, in one place.

↗

Performance

A listing can be getting plenty of traffic on eBay and still be underperforming against what it should deliver after fees. Performance tracks sales trends, orders and refund rates on eBay alongside every other channel, so you can tell what’s actually driving growth.

▢

Restock

A stockout on a well-performing eBay listing doesn’t just lose the sale. It resets the listing’s visibility once it’s back in stock, and Restock flags low inventory automatically, before you run dry.

↻

Replan

Not every product deserves a second order, especially once Final Value Fees and Promoted Listings spend are accounted for. Replan shows you which products are actually worth reordering, based on real sales and margin performance, not just what’s moving.

🚚

Sourcing

You know a product is selling on eBay. What you don’t always know is whether your supplier can restock it in time to protect your listing. Sourcing tracks supplier lead times alongside your sales pace, so restocking decisions reflect real turnaround.

✉

Engage

eBay’s Top Rated Seller status depends on fast responses and low unresolved-issue rates. Engage keeps every customer message and support ticket in one inbox, so nothing slips through and your standing stays protected.

◆

Workspace

Scaling on eBay brings its own listing, content and compliance demands. Workspace takes on the listing copy, product imagery, variation and bundle setup, quality assurance and day-to-day support, so growth doesn’t cost you your week.
