Choosing the Right Platform Changes Everything
Not all online auction platforms are created equal. Whether you're a buyer hunting for a bargain or a seller trying to reach the right audience, choosing the wrong platform can mean lower prices, slower sales, or a frustrating experience. Here's an honest breakdown of three major platforms — eBay, Catawiki, and Invaluable — to help you decide where to focus your efforts.
eBay: The World's Largest Marketplace
eBay is the default for most people entering the online auction world, and for good reason. Its sheer scale — hundreds of millions of active buyers worldwide — means your item is seen by more eyes than on any other platform.
Best For
- Consumer electronics, fashion, and everyday collectibles
- Sellers who want speed and volume
- Buyers looking for competitive pricing on common items
Considerations
- High competition means prices for common items can be very low
- Seller fees include a listing fee and a final value fee (typically 10–15% depending on category)
- Fraud risk is higher due to the open marketplace model, though buyer protection is robust
- Best results come from detailed listings and strong seller feedback scores
Catawiki: The Curated Specialist
Catawiki positions itself as a curated auction house for "special objects." Every lot is reviewed by an in-house expert before it goes live, which means higher quality control and a more educated buyer base willing to pay for quality.
Best For
- Antiques, art, jewellery, watches, wine, and rare collectibles
- Sellers with genuinely interesting or unusual items
- Buyers seeking authenticated, appraised pieces
Considerations
- Not every item is accepted — the expert review process filters out common or low-value lots
- Seller commission is significant (typically around 20%), but the specialist audience can offset this with higher final prices
- Auctions run on a scheduled weekly cycle, so there's less flexibility on timing
- Anti-sniping time extensions mean sniping tactics are ineffective here
Invaluable: The Auction House Aggregator
Invaluable (formerly AuctionZip) is different from eBay and Catawiki in a fundamental way: it aggregates live auctions from thousands of traditional auction houses worldwide, letting you bid in real time through a single platform.
Best For
- Fine art, estate sales, and high-value antiques
- Buyers who want access to traditional auction house inventory without attending in person
- Serious collectors looking for provenance-backed items
Considerations
- Buyer's premium (charged by the auction house, not Invaluable) can add 20–25% to the hammer price
- The interface and buying process vary by auction house
- Primarily a buyer-focused platform — individual sellers list through partnered auction houses, not directly

The Bottom Line
If you're selling everyday collectibles or electronics, start with eBay for reach. If you have a genuinely special item with clear value, Catawiki's specialist audience may deliver a better price despite higher fees. If you're a serious buyer hunting for fine art or estate pieces with full provenance, Invaluable gives you access to the traditional auction world from your screen.
Many experienced buyers and sellers use all three platforms strategically, matching the item type to the platform where it will perform best.
