Selling something second-hand without being scammed

Most advice about buying second-hand is about not being cheated by the seller. The reverse case gets far less attention and has a specific structure: when you are the one selling, the fraud runs on the payment rather than on the item, and it works because you are focused on whether the buyer is real rather than on whether the money is.

A second-hand sale is a private transaction between two people with no employer, no contract department and no automatic protection behind either of them, and selling safely comes down to one principle: do not part with the item until the money is irreversibly yours. Almost every technique in this article is a way of establishing that, and almost every scam is a way of blurring it.

How does a second-hand sale actually go wrong?

Five patterns account for most second-hand sale fraud, and they share a shape.

The overpayment. The buyer "accidentally" sends more than the price and asks for the difference back. The original payment is later reversed, and the refund you sent was real money. The refund is the theft.

The fake payment confirmation. A screenshot or an email that looks like a payment notification. It arrives before the money does, and often the money never does. Trust your own bank, not a message.

The shipping agent. A buyer who cannot collect and insists on their own courier, frequently with a request to send before payment clears. The courier is theirs.

The friends-and-family transfer. A payment sent through a route with no buyer protection, which is presented as saving fees. It also removes every mechanism you might use to dispute.

The out-of-platform move. "Let's continue on WhatsApp." Once you are off the marketplace, its protection, its records and its dispute process no longer apply.

The pattern is always the same: create a reason for the money to move in a way you cannot reverse, or for the item to move before the money settles.

The rules that cover almost everything

Six rules cover almost every second-hand sale, and the first two prevent most of it.

1. Wait for cleared funds in your account. Not a notification, not an email, not a screenshot. Open your banking app yourself and confirm the balance changed.
2. Never refund an overpayment. Ask the buyer to reverse the original payment through their own bank. If they overpaid genuinely, that route works perfectly.
3. Use the platform's own payment and messaging. Both exist to give you a record and a dispute path, and moving off them removes both.
4. Meet in a public place for local sales, ideally somewhere with cameras — a café, a supermarket entrance, a police station car park where the scheme exists.
5. Post only with tracking and proof of delivery, and keep the receipt. Without it, a claim of non-delivery is unanswerable.
6. Do not use a courier the buyer arranges. Book it yourself, even if they offer to pay.

Rule one is the whole article compressed. Everything else is an elaboration of it.

Writing the listing so it protects you

The listing for a second-hand sale is a document you may need later, and four things make it one.

Photograph honestly, including flaws. Scratches, wear, a missing accessory. A buyer who sees the flaw in the listing cannot claim it was hidden, and this single practice prevents most non-fraudulent disputes too.

Photograph identifying details. A serial number, a distinguishing mark. If an item comes back in a return, this is how you prove it is the same one — item-swap returns are a real category, and this is the defence.

Describe the actual condition in words. "Works, screen has a scratch bottom-left" carries more weight than "good condition".

State the terms. Collection only, payment method, no returns if that is your position. Ambiguity is what disputes grow in.

For anything of value, sending a written record — a simple invoice with the item, condition, price and date — is worth the two minutes. An invoicing tool such as Ordava does this from a phone, and the point is not formality: it is that both sides now have the same account of what was agreed, which is exactly what is missing when a dispute starts.

Which payment method to accept

The payment method in a second-hand sale decides how much of the risk you are carrying, and the differences are larger than the fee differences that usually drive the choice.

Two rows deserve comment. Card payments can be charged back long after the item is gone, which is why they suit buyers and expose sellers — for a valuable item, the platform's own checkout with its dispute process is better than accepting a card directly. And friends-and-family transfers remove protection from both sides, which is precisely why a stranger proposing one is telling you something: they are not saving you a fee, they are removing your recourse.

Cash in person remains the cleanest arrangement for a local sale of anything under a few hundred, for the simple reason that it settles completely at the moment of handover and nothing can undo it afterwards.

What is the safest way to hand it over?

The safest form of sale, with four things to get right.

Meet in daylight, in public, ideally with someone with you for a high-value item.

Let them inspect it fully before money changes hands, and be present while they do. Most in-person disputes come from a buyer feeling rushed.

Confirm the payment on your own device before handing over the item. For a bank transfer this means seeing the balance in your app; for cash it means counting it.

Do not accept a cheque, and be cautious with any instrument that clears slowly. Anything reversible after collection is a risk you are carrying alone.

If a buyer will not meet in public, will not let you confirm payment before handover, or applies pressure about time, those are three separate reasons to end the sale. You are allowed to change your mind about a transaction, and a genuine buyer will find that normal.

Shipping without exposure

When a second-hand sale is posted rather than collected, five specifics apply.

• Track everything, always. The cost is small against the value of the claim it prevents.
• Require a signature for anything valuable.
• Photograph the item packed and the label before it goes, so its condition at dispatch is documented.
• Send to the address the platform gives you, never one supplied in a message. A changed delivery address is a common way to defeat seller protection.
• Post only after funds clear, including any holding period the payment method has.

The fourth one is subtle and it matters: seller protection generally applies to the address on the order. Shipping somewhere else, however reasonable the request sounds, voids it silently.

If it goes wrong

If a second-hand sale goes wrong, order matters, and the first two steps are time-sensitive.

1. Contact your bank or payment provider immediately if a payment reverses. Speed affects outcomes.
2. Report it through the platform while the messages and listing still exist. Platforms delete conversations, and the record is your evidence.
3. Report to the national fraud service. It rarely recovers money and it does contribute to shutting accounts down.
4. Keep everything — messages, tracking, photographs, the listing itself. Screenshot rather than assume the platform retains it.
5. Do not engage further with the buyer. Once you know, further contact adds nothing and gives them more to work with.

The short version

When you are selling, the fraud is on the payment, not the item. Wait for cleared funds in your own banking app before the item leaves your hands, and never refund an overpayment — ask the buyer to reverse it through their own bank instead.

Stay on the platform's payment and messaging, meet in public or ship with tracking to the platform's address only, photograph flaws and serial numbers before listing, and book any courier yourself. A buyer who resists any of that has told you which of the five patterns you are in.
