Inventory discipline: how top sellers avoid costly mistakes

Edited by Thomas | 24 September 2025 Picture this: a buyer places the highest bid and pays happily. And then… you realise the object is missing, damaged, or sold elsewhere. You’re forced to cancel. For the buyer, it’s frustrating. For you, it means a broken promise, a negative mark on your record and lost trust. The buyer’s perspective when you can't supply Imagine bidding hard for an object, only to hear ‘Sorry, it’s not available.’ Disappointment like this pushes buyers away, sometimes for good. Why inventory discipline matters Good inventory management is a key part of seller success. It ensures that when your object sells, you can deliver exactly what you promised. • In 2024 alone, thousands of bidders saw objects they had bid on withdrawn before the auction ended. Each case damages buyer confidence – not just for that seller, but in the marketplace as a whole. Remember: after your object is approved, the auction submission is final. Removing it – particularly once live – breaks trust with buyers and impacts the expert’s work. How top sellers manage inventory Here’s how top sellers avoid those mistakes: 1. Keep stock reserved once submitted When you submit an object to Catawiki, consider it ‘off the market’. Don’t list it elsewhere – online or offline. 2. Use clear tracking systems Whether you use an inventory tool, a spreadsheet or labelled boxes – know where each object is. This prevents last-minute surprises. 3. Perform regular audits Do regular checks to confirm that your listed inventory is still available, accurate and ready to ship. 4. Build a buffer If you’re sourcing regularly, only submit objects that you already have in hand. You have an obligation to supply the object after a successful auction. Only sell what you can actually ship.

Important: You may not transfer shipping of objects to any third party (such as the manufacturer, a wholesaler, a retailer, or a fulfilment house) which then ships the object directly to the buyer. Dropshipping in any form is strictly forbidden.
5. Communicate early if issues arise If an issue arises, withdraw the object before the auction goes live. Better early than a last-minute cancellation. You can withdraw before the auction starts in the Orders page. In summary
Inventory discipline might not sound exciting, but it’s one of the most powerful ways to earn trust. Buyers trust sellers who never cancel. Trust equals bids, repeat buyers, and long-term growth. Top sellers don’t just curate great objects – they deliver, every time. You might also like: Why shipping costs can make or break your sale
