Before Production Use

2. Test Import: Try importing without "Replace All" first
3. Verify Results: Check all products, variants, and categories created correctly
4. Review Logs: Check application logs for any warnings or errors

Post-Import Verification

1. Navigate to Products page - verify product count
2. Check Categories page - verify all 4 categories exist
3. Open individual products - verify variants are created
4. Test ordering workflow through TeleBot (if applicable)

Support & Troubleshooting

Common Issues

Issue: Import fails with "Missing required column" error Solution: Ensure CSV has all required headers matching the template

Issue: Categories not created Solution: Categories are auto-created - check application logs for confirmation

Issue: Variants not showing Solution: Verify variation format matches Name:Qty:Price;Name:Qty:Price

Issue: Price showing as 0 Solution: Check CSV uses decimal format (e.g., 10.00 not £10)
