NetAuctionHelp uses an account model to generate revenue.  Anyone wanting to post items for sale must be registered and have an account with your site.
Sellers add money to their account using PayPal, credit card processing, or custom processing designed specifically for your site.  When funds are added to an account, they are added to your PayPal or merchant account and NetAuctionHelp keeps track of account balances.

When posting items for auction, sellers are charged a small inclusion fee and this fee is deducted from their account.   This fee is based on a table of price ranges.
For example, items posted at a price between $125 and $499 might require an inclusion fee payment of $5.  This table-driven inclusion fee value can be easily customized by you.

When an item sells in an auction, a small selling fee is charged to the seller and deducted from their account.   For example, a fee equal to 5% of the selling price might be charged.

Both the inclusion fee and selling fee are deducted from the seller's account - the inclusion fee when posting the item and the selling fee when the item sells.

So, the seller must keep sufficient funds in their account to cover these transactions.  To cover these fees, the seller uses the My Area section of your auction site to add funds to their account.  Each time a seller adds funds to their account, you make money!

If you elect to use PayPal, you can plug your site directly into your PayPal account with one line of code.  Or, if we are managing your site for you, we'll do it!  You can, of course, modify NetAuctionHelp (or have us do it for you) to perform whatever specific e-commerce processing you need.
