Legitimate Marketplace Buyer vs Fake Buyer Scam
How genuine buyers on online marketplaces behave versus scammers who target sellers.
Last reviewed: 1 June 2026
Most people who message about your listing are ordinary buyers. They ask a question, they haggle a little, they pay through the platform and arrange a normal collection or delivery, and the transaction closes without drama. Fake buyer approaches feel different in ways that are easy to rationalise at the time. They arrive fast, often first, and they are enthusiastic and slightly over-generous. They ask to carry on the conversation by text or a messaging app because it is easier, they send something that looks like a payment confirmation, and they need it posted today. Some overpay and ask you to return the difference. The pressure works because you want the item gone. The one thing that decides it is whether the money is genuinely in your own account when you look for yourself.
Side-by-side comparison
| Legitimate buyer | Fake buyer | |
|---|---|---|
| Payment method | Pays via the platform's supported, traceable methods | Pushes off-platform payment: bank transfer, crypto, or gift cards |
| Overpayment | Pays the listed price; no cheque or excess transfer | Sends a cheque or transfer for more than the price; asks you to refund the difference |
| Urgency | Reasonable timeline; no extreme pressure to ship immediately | Needs the item shipped today before 'payment clears' |
| Communication | Communicates via the platform's messaging system | Steers you to email, WhatsApp, or a link outside the platform |
| Payment confirmation | You can verify payment in your account before shipping | Sends a fake payment screenshot or email claiming funds are held |
| Shipping | Uses standard shipping; doesn't insist on a specific courier with a 'special code' | Insists on a specific courier or shipping agent that is part of the scam |
Common red flags
- First contact steers you to communicate off-platform
- Request to accept payment outside the platform's supported methods
- Overpayment with a request to refund the difference
- Urgent pressure to ship before payment is verified in your account
- Fake payment confirmation email or screenshot
- Insistence on a specific courier or shipping agent you've never heard of
Verification steps
- Verify payment is in your actual bank or platform account before shipping anything
- Keep all communication within the platform's own messaging system
- Be suspicious of offers significantly above your listed price
- Check the buyer's profile history, reviews, and account age
- Report suspicious offers to the marketplace before engaging further
What not to do
- Don't ship before you can independently verify payment in your own account
- Don't refund any 'overpayment' — a genuine buyer won't overpay
- Don't communicate via personal email or messaging apps to close a sale
- Don't use a shipping agent or courier the buyer insists on
A safe response
You are allowed to slow a sale down. Tell the buyer you post once payment has cleared and that you keep everything on the platform, then stop replying to messages that push elsewhere. Check your own bank app or platform balance directly, not a screenshot or an email, and remember that a pending or reversed transfer is not cleared money. Never refund an overpayment; ask the sender to reverse it through their own bank. If you have already posted the item or sent a refund, report it to the marketplace and to your bank straight away, keep the messages and tracking, and report it to your national fraud authority.
Frequently asked questions
What is the overpayment scam and why does it work?
The scammer 'overpays' via a bouncing cheque or reversible transfer and asks you to refund the difference. You send real money; their payment later reverses. You lose the difference and potentially the item too.
Is it safer to sell on platforms with buyer/seller protection?
Yes, but only if you stay within the platform's ecosystem. Scammers specifically try to move transactions off-platform to bypass those protections. Insisting on in-platform payment is the core defence.
What should I do if I've already shipped after a fake payment?
Report it to the marketplace and to your national fraud authority. Contact your bank if you sent any refund or made any payment. Recovery is difficult once goods are shipped, but reporting helps prevent the scammer targeting others.
