Why this matters
- Right-size the box. If volumetric wins, a smaller carton cuts the bill without touching the product.
- Check the divisor per carrier. The same box can bill differently on different rate cards.
- Catch it at booking. Recording dimensions on the docket means billing surprises surface before dispatch, not on the invoice.
