How to Manage and Sell Steam Inventory Items Automatically

The Inventory Manager feature allows you to manage your Steam inventory directly within SGI, including the ability to view all your marketable items (trading cards, foil cards, emoticons, backgrounds, and more) and sell them on the Steam marketplace.

This feature uses an undocumented Steam API endpoint with strict rate limits to fetch card prices. If you encounter errors while selling card or fetching card prices, please try increasing the Sell Delay, or wait a few minutes before trying to fetch card prices again

Pricing Details

When you use List All, SGI will list each item at its highest_buy_order. If that price isn't available, it will use its lowest_sell_order. If neither price is available, the item won't be listed.

You can choose which option to use by default by changing the Default Sell Option in the settings.

Marketplace Fees

Steam charges a 15% transaction fee on each marketplace sale, which is made up of two parts:

  • Steam Transaction Fee (5%): This goes to Valve for facilitating the transaction.
  • Game Publisher Fee (10%): This goes to the publisher of the game the item is from (not just Valve games—all publishers receive this fee for their own items).

SGI automatically accounts for the 15% Steam transaction fee when you set a sale price. The price you enter is what the buyer pays — SGI works out the correct listing price so that the buyer pays exactly that amount.

If you set a price of $0.50, the buyer pays $0.50 and you receive $0.44 after fees.
