# Shipping Rates Wrong at Checkout? How to Stop Over- or Undercharging

Wrong rates usually come from missing product weights, no package sizes, mis-set shipping zones or rules that conflict. Fix the product data first, then use carrier-calculated rates or simple flat rates that you test against real shipping costs.

- **Starting price:** From $600

- **Where:** Remote, anywhere in the U.S.

- **Quote:** Fixed price before work starts

## Try this first

- Check that every product has an accurate weight
- Add your real box sizes
- Review shipping zones and rate rules
- Place test orders to near and far addresses
- Compare checkout rates with your actual label costs
- Consider carrier-calculated rates or simpler flat-rate tiers

Common causes

- Products with missing or default weights
- No box sizes, so dimensional weight charges surprise you
- Shipping zones or rate tables set up wrong
- Free shipping rules conflicting with other rates
- Carrier-calculated rates not enabled on your plan

If you ship heavy, oversized, perishable or international orders, rates need custom rules or a shipping app.

## Questions

### What is dimensional weight?

Carriers charge by package size when a box is large for its weight, which surprises many sellers.
