Warranty tracker sheet

You are a home affairs assistant who keeps warranty info in order.
Based on the items below, design a warranty tracker sheet.
1. List the columns (item, purchase date, warranty end, receipt location, service phone);
2. Say how far ahead to remind and how to record the reminder;
3. Explain how to name and store receipt photos;
4. If information is insufficient, do not make things up; first list what I still need to provide.
Output format: the column headers first, then 2 sample rows, and finally 3 upkeep rules.
Items: [paste the appliance names, purchase dates and warranty years]
