After the sale

After the sale, do not immediately delete everything related to the transaction.

For a reasonable period, keep at least:

• a copy or reference to the listing;
• relevant photos;
• serial number;
• final agreement;
• payment confirmation;
• receipt or tracking information;
• records of disclosed modifications or defects.

There is no need to accumulate unnecessary data. Keep what is sufficient to clearly reconstruct what was sold and under which conditions.

After delivery, the buyer may ask questions about operation, accessories, a modification or a detail already discussed.

Reply using verifiable information and the terms that were agreed. If you can help with a simple explanation, do so, but do not take on technical responsibility for something you are not qualified to assess.

Good documentation from before the sale makes it easier to distinguish a straightforward question from a genuine problem report.

If the buyer reports that something is not working, avoid immediate conclusions.

Ask for specific information:

• which function has the problem;
• when it occurs;
• how the item was connected or powered;
• photos or video where useful;
• any visible damage to the parcel;
• whether the issue concerns a defect that was already disclosed.

Compare this information with the documentation created before the sale.

Shipping damage may require a different process from a functional issue or from a characteristic already described in the listing.

If the sale enters a return or dispute process, organise the following:

• original listing;
• pre-sale photos;
• serial number;
• relevant messages;
• final agreement;
• payment information;
• shipping documentation;
• material supplied by the buyer about the reported issue.

Follow the official procedures applicable to the transaction and do not create improvised alternatives.

If the item is returned, document the condition of both the parcel and the item when it arrives back.

Documentation does not automatically guarantee a particular outcome, but it makes the sequence of events much clearer.

After completing the sale, look at where you spent the most time and where the most questions arose.

Ask yourself:

• were important photos missing?
• was the model identified precisely enough?
• was the price positioned correctly?
• did the description repeatedly generate the same questions?
• were shipping terms clear?
• had you defined your negotiation floor properly?

Turn the answers into a personal checklist.

Over time, this makes preparation, publishing and negotiation faster without reducing the quality of information provided to the buyer.
