Surplus stock is stock that did not sell: end-of-line items, returns, a cancelled order, a failed product, or the contents of a business that is closing. The people searching for how to sell it want to know who buys it, how quickly and at what discount. This guide covers what we could find on the routes in Australia and what to settle before you commit. Most sources are stock buyers and auction houses marketing their own services, plus some overseas liquidation sites, so we treat claims as claims and give no prices. It sits beside our guides to selling business equipment when you close down and selling used commercial and industrial equipment. ScrapTrade runs a scrap marketplace and has a commercial interest in the scrap trade.
Who buys surplus stock
- Specialist excess stock buyers. They take bankrupt stock, which is stock from companies going out of business, end-of-line items and returned goods. One Sydney buyer says it buys all quantities down to a single pallet or carton.
- Competitors, online resellers and discount retailers. Any of them may take stock in bulk if they can move it fast.
- Auction houses. Specialist surplus auctions handle the marketing and hosting, and most are held online. One describes it as one of the fastest and simplest ways to sell excess stock.
- Liquidators. US sources describe liquidators buying inventory outright through buyout agreements for immediate cash and taking over the reselling. We did not find an Australian description, so check how it works here.
Expect a steep discount
Stock buyers generally expect to pay well below full value, and the sources agree that waiting does not usually help. One Australian buyer warns that the first offer you get is normally the highest, and another source says it has never seen the price of surplus stock rise while it sat in a warehouse. Both are from the businesses that buy stock, so read them as their view and not as a law. The point stands that storage and write-downs have a cost, and the longer the stock sits, the less leverage you have. Decide your floor price before you start, so you know when to say yes.
What to settle before you sell
- A clear list. Item, quantity, condition, packaging and whether it is boxed, palletised or loose.
- What you are allowed to sell. Stock under a distribution agreement, a brand licence or a lease may not be yours to dispose of, and we did not research this, so check your contracts.
- Who collects, and when. Warehouse space and rent are a reason to move quickly.
- How you are paid. Before collection, on collection or after the auction settles.
- GST and tax. Our search returned nothing on GST for stock sales or on how a stock sale fits into winding up a business. Confirm with the ATO or an accountant. Our guide to closing a business covers the equipment side.
- Records. Keep invoices, lot lists and receipts.
Scrap as the floor
Some surplus is metal, and when no buyer wants it as stock, the metal has a value by weight. Our guides to scrapping copper cable, electric motors and aluminium prices explain how yards value sorted metal. Do this last, because stock is worth more as stock if anyone will buy it, and some goods, such as electronics, carry data and need care, as our guide to IT asset disposal explains.
Questions to ask a stock buyer or auction house
- What do you pay, or what is the reserve? And what fees come out of the sale?
- Do you take mixed lots, or only full lines?
- Do you take stock with damaged packaging, expired dates or missing parts?
- How and when do I get paid, and who collects?
- Can I see the terms in writing, and who have you sold for? We cannot vouch for any buyer, and sources were marketing pages, so check reputation before you hand over goods.
Where ScrapTrade fits
ScrapTrade is a scrap marketplace and not a surplus stock auction, and most stock belongs with a stock buyer or an auction. It may suit surplus that is metal, or that has become scrap: offcuts, fittings, cable, motors, components and the like. Listing is free and no commission is taken, you negotiate in chat and the buyer's 5 percent deposit is held in escrow once a bid is accepted. Businesses and individuals can sell after verification, and buyers in more than 50 countries bid. Whether general stock or mixed lots are accepted is not something we could confirm, so ask cs@scraptrade.com.au first.
