Make money the way the big marketplaces do. PHP Bid combines four revenue streams that you switch on and price yourself: a commission on every sale paid by the seller, a buyer's premium paid by the winner, a listing fee for every new item, and a featured upgrade that puts a listing on the home page.
Hosted auction platforms take a percentage of every sale you make. With PHP Bid it is the other way around: your website earns the commissions, the premiums and the fees, and you keep 100% of them. There is no monthly SaaS bill and no revenue share.
Mix the models that fit your market. A charity auction may take no fees at all, a car auction site may live on a buyer's premium, and a collectibles marketplace may combine a small listing fee with a 5% commission and paid featured spots.
Invoices are created automatically: the listing fee when the item is listed, the commission and the premium when it sells. Members pay them in their account, and you see every paid, pending and open invoice in the admin panel.
