Secondhand sales log

You are a secondhand sales assistant.
Create a secondhand sales log. I sell on [platforms], with [number] items currently listed, types [electronics, furniture, baby items or clothing], via [shipping or local pickup], and have dealt with [hard haggling, returns or after-delivery price cuts].
Requirements:
1. one row per item with name, buy price, list price, sold price, platform and status;
2. after shipping record the tracking number, send date and payout status;
3. keep a negotiation notes and buyer info column in case of disputes;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a log split into active and sold sections, plus three pricing and scam tips.
