Reseller shipping guide

Pack accurately. Ship confidently.

Protect the item and your margin by packaging first, recording the full parcel size and weight, and verifying current shipping costs.

Follow the shipping workflow

Six practical steps

Estimate from the packed parcel.

  1. 1
    Step 1

    Choose protective packaging

    Match the box, mailer, padding, and moisture protection to the item's size, weight, fragility, and carrier requirements. Avoid packaging that is too weak or unnecessarily large.

  2. 2
    Step 2

    Pack before measuring

    Estimate shipping from the packed parcel, not the bare item. Include the box or mailer, padding, tape, inserts, and every accessory the buyer will receive.

  3. 3
    Step 3

    Weigh the complete parcel

    Use a suitable scale and round according to the carrier's current rules. A missing ounce can change the eligible service or postage charge.

  4. 4
    Step 4

    Measure all dimensions

    Record length, width, and height at the parcel's widest points. Large packages may be priced by dimensional weight or subject to additional charges.

  5. 5
    Step 5

    Compare eligible services

    Check current carrier rates, delivery estimates, tracking, insurance, destination limits, and marketplace requirements before selecting a service.

  6. 6
    Step 6

    Verify before handoff

    Confirm the item, buyer address, service, parcel weight, dimensions, label, tracking, and required acceptance scan before the package leaves your control.

Shipping costs to record

Postage
The carrier charge based on service, destination, packed weight, dimensions, and current rates.
Packaging
Boxes, mailers, tape, labels, padding, sleeves, and protective material used for the order.
Coverage
Any insurance, signature, or other service selected for the shipment.
Marketplace effects
Selling fees may apply to shipping collected or the total buyer payment; verify the marketplace's current rules.

Free shipping still has a cost

When the buyer sees free shipping, you still pay for postage and packaging. Estimate those expenses before listing, include them in the item price, and check that the remaining profit meets your goal.

Frequently asked questions

Reseller shipping questions

Should I weigh an item before or after packaging?

Use the complete packed parcel for the shipping estimate. The box or mailer, padding, tape, and included accessories all affect weight and dimensions.

How should resellers handle free shipping?

Estimate postage and packaging before setting the item price, then include those expected costs in the price and profit calculation. Free shipping removes a separate buyer-facing shipping charge; it does not remove the seller's expense.

Why do package dimensions matter?

Carriers may use dimensions to calculate billable weight or additional charges, especially for larger parcels. Measure the packed parcel at its widest points and follow the carrier's current rules.

Does Inzoly buy or print shipping labels?

No. This guide is educational. Verify rates, labels, services, addresses, and carrier requirements through the marketplace or shipping provider you use.

Check your starting margin.

Calculate sale price, item cost, gross profit, and margin, then account separately for shipping, fees, returns, and other expenses.
