What Is The Markup Control Page?

Last updated: April 16, 2026

Pick how much profit you want on each item Infinity lists for you.

What This Page Does

When Infinity lists a product on your eBay store, it needs to know how much to charge. Markup Control is where you tell Infinity your profit margin. The profit margin is how much more than the Amazon price you want to sell for.

Example

Let's say Infinity wants to list a product that costs $20 on Amazon.

  • If your margin is 50%, Infinity will list it on eBay for about $30.
  • If your margin is 100%, Infinity will list it for about $40.
  • If your margin is 25%, Infinity will list it for about $25.

A higher margin means more profit per sale, but it also means your price is higher than other sellers, so you might sell fewer items. A lower margin means you sell more often, but you make less on each sale. Most sellers start at 50% and adjust from there.

How To Use It

  1. Open the Markup Control page from the sidebar.
  2. Pick your margin percentage. You can go with Infinity's default or type in your own number.
  3. Save. From now on, every new listing uses this margin.

Why It Matters

  • You control your prices. Infinity handles the math, but you set the rules.
  • You can change it anytime. If sales are slow, drop the margin a little. If you are selling too fast and want more profit per sale, raise it.
  • It applies to new listings. Changing your margin does not re-price items that are already listed.

Try 50% first. Watch how many items sell over a week or two. Then bump it up or down based on what works for your store.
