Use a room-by-room schedule with a laying plan. Ask the supplier to state the shade, size and production references used for the supplied cartons, and have the installer review layout and allowances before ordering. Keep any later top-up request tied to the original records; do not assume a new batch will match.
| Record | What to make explicit |
|---|---|
| Measured area | Keep floor and wall measurements separate and identify estimated dimensions. |
| Layout | Record direction, pattern, cuts and edge treatments for installer review. |
| Batch identity | Ask which carton markings identify shade, size and production batch. |
| Order quantity | Show net requirement, cutting allowance, agreed spares and carton rounding separately. |
| Changes | Review replacements or top-ups against the original sample and batch record before approval. |
Take this into your next conversation.
- Use one room/model schedule.
- Photograph or retain carton labels.
- Agree spares rather than assuming a fixed percentage.
- Keep later batches separately identifiable.
