Shipping label price adjustments
A shipping label price adjustment occurs when you purchase a shipping label and the carrier determines that you've chosen an incorrect shipping rate. After you have shipped your order, the correct postage amount is verified by USPS or Canada Post. If you pay an incorrect amount to ship the order, either too little or too much, then your carrier will credit or debit your account for the difference. Your package will still be delivered even if there is an adjustment.
Price adjustment is a standard industry practice and all service providers follow this standard, so it's important that your shipping labels are accurate.
Reasons for price adjustments
If your shipment is identified as needing a price adjustment, then the adjustment will show up in the order's timeline. The price adjustment is automatic and you'll receive a charge or credit to your Shopify account, which will appear on your next invoice.
The following examples are possible reasons for price adjustments:
- label package weight doesn't match actual weight of shipment
- label package dimensions don't match actual dimensions of shipment
- using a flat rate label with a non-flat rate box, or using a non-flat rate label with a flat rate box
- using an incorrect mail class (for example, if packaging weight is above the maximum threshold for that mail class)
- return to sender fees.
You can avoid overpaying or underpaying for your shipping labels by making sure that your shipping and product settings are accurate.
There are a few things you can do to to make your shipping labels more accurate:
- Weigh the item that you're shipping and enter the weight into its product details page.
- Measure and weigh your packaging.
- Make sure that your shipping origin and shipping destination zones are correct.
- Review your carrier's mail classes to make sure your shipment is classified properly.
