Why Standard Markups Fail on Marketplaces
Many sellers make the mistake of adding a markup to the source cost without accounting for the fact that eBay deducts its fee from the final gross transaction amount (including shipping and taxes).
By solving for the gross listing price in reverse, this algorithm guarantees that even after eBay takes their 12.9%–15% cut, your exact dollar margin remains protected.
The Need for 24/7 Price Monitoring
Calculating prices manually works for 5 items, but breaks completely when managing 500 to 5,000+ SKU catalogues:
- ✕Amazon prices adjust dynamically multiple times per day based on algorithms and seller competition.
- ✕Suppliers run out of stock without notice, risking eBay out-of-stock cancellation defects.
- ✓Our custom automation scripts poll supplier feeds, recalculate target margins, and push updates through the eBay Trading & Inventory APIs automatically.
