Building and Using Your LitBuy Spreadsheet
Create a sheet per supplier with the following structure for longitudinal analysis:

| #LB-001 | Jan-2024 | 12 | 98% | No | Perfect order. |
| #LB-002 | Mar-2024 | 25 (Delay notified) | 95% | Yes, 5% partial | Minor color variance, seller compensated promptly. |
| #LB-003 | May-2024 | 15 | 99% | No | Consistently improving. |
