How Materials Broker works

Full details →
  1. ListSellers post surplus with photos, quantity, condition and a price, or ask for offers or quotes. Standard listings publish at once.
  2. BidTimed auctions run by the broker desk with proxy bidding, bid increments, reserves and a soft close. Bids are binding.
  3. Buy or offerFixed-price and Make Offer listings, where those are open, go through an order the desk reviews for tax and freight before you pay.
  4. Request a quoteFor specifications, volume or anything in the Supply Catalog, the desk sources it and confirms price and availability in writing.
  5. Pickup or freightPickup, buyer-arranged freight or a seller’s own delivery; the desk gets freight quotes where needed. Addresses are shared after a deal.
  6. Broker-assistedThe desk relays buyer inquiries, vets bidders, invoices winners and holds seller contact details until a transaction is agreed.

What you see is what the record says: “Materials Broker Verified” appears only after the desk has confirmed price, quantity and condition itself; “Seller reported” is the seller’s own recent confirmation. We do not warehouse, haul or manufacture, and we do not guarantee a sale or a transaction. Terms · FAQ
