Edit a shipment after a sale

Whatnot Support Whatnot Support

Shipping adjustments let you edit your shipment details after a sale or Giveaway, so your label matches what you’re actually sending.

If your label doesn’t match your package, it may be delayed, refused, or charged additional postage. If something's off, it’s important to update your shipping details before you ship.

Shipping adjustments are best for occasional fixes, not as a replacement for accurate shipping setup.

When to use a shipping adjustment

Use a shipping adjustment if:

  • Your package weight or dimensions are different than expected
  • You want to bundle multiple orders into one shipment
  • You need to split items into separate shipments
  • You want to change the shipping service (US only)
  • You want to add extras like insurance or signature confirmation (US only)

For help with any other label changes, check Change or fix your shipping label.

What happens when you adjust a label

When you make a change:

  • If you haven’t generated a label yet, your updates are applied before it’s created.
  • If a label already exists, it’s voided and replaced with a new one.
  • Shipping costs may change, depending on your updates.

You’ll see any cost changes before you confirm.

When you can make changes

What you can update depends on where your shipment is in the process:

  • Before you generate a label: You can bundle items into one shipment.
  • After you generate a label, but before you drop it off: You can update the weight, dimensions, or shipping service.
  • Until the package is in transit: You can still split bundled items into separate shipments.

Once the package is in transit, you won’t be able to make a shipping adjustment. 

How to make a shipping adjustment

You can edit a shipment on whatnot.com. Shipping adjustments aren’t available in the app. 

  1. From Seller Hub, open the Shipments page
  2. Select the shipment 
  3. Click Edit Shipping Details (before generating a label) or Generate New Label (if you already generated one)
  4. Make your updates
  5. Scroll down to Shipping Costs > Pending Adjustments to review any cost changes
  6. Save or generate your new label

If a new label is created, the original label is voided. 

Note: Always use the latest version of your shipping label to avoid issues with delivery, tracking, and payout.

Costs and free shipping adjustments 

Shipping costs are priced and charged at the time of sale. 

If you update shipment details later, the label cost may change.

  • Some adjustments are always free
  • Some are free up to a weekly limit
  • Some always cost extra

If your new label costs more, the difference is charged to your account balance and shown in your ledger.

If the shipping adjustment costs less, Whatnot won’t issue a refund.

You’ll see whether an adjustment is free or costs extra before you save your changes. 

How costs work by region 

Adjustment types, costs, and free limits depend on where you ship from.

    • Between 1–5 lbs: e.g. 2 lb → 4 lb
  • Weight changes for Flat Rate Boxes, if Flat Rate was applied before the sale or show (e.g. 3 lb → 15 lb still ships Flat Rate)
  • Bundling shipments, when the combined label cost is less than two separate ones
