Choose the route that suits the stock
Outright trade purchase
For selected stock that makes commercial sense, AO may offer an agreed trade price. Payment follows delivery and inspection, normally within up to 10 working days unless otherwise agreed in writing.
Seller-held consignment
For valuable specialist or slower-moving stock, the seller can retain ownership while AO markets it. Standard commission is 20% of net sale proceeds after agreed third-party costs, subject to individual terms.
Brokerage
Where it makes sense to connect a specific buyer with a seller, AO can qualify and negotiate the enquiry with agreed terms before a transaction.
Frequently asked questions
Do you buy single Siemens modules?
Yes, individual modules can be considered. Small or low-demand items may be more suitable in a grouped lot.
Can I send just a spreadsheet?
Yes. Include part numbers and quantities first; photos and condition details can follow. Submit the inventory for assessment.
Are high online asking prices a guide to your offer?
Not necessarily. Trade offers account for achieved demand, condition, testing, sale time, fees, returns and risk. Consignment can be a different option when a trade offer is unsuitable.
Have surplus Siemens equipment?
Use the existing AO seller portal to send stock details and receive an enquiry reference; you can then send supporting photographs or spreadsheets. No guarantee of purchase is implied.
