Shipping Label Costs
RelistKit tracks what shipping does to your profit with almost no work from you. This article explains what happens automatically, and the one number we ask you to enter, marketplace by marketplace.
The short version
- The selling price and fees come in with each sale. With automatic sale detection, you never type those.
- On eBay and Depop only, we ask for one number after a sale: what the shipping label actually cost you. Enter it when you buy the label, and your profit is exact.
- Poshmark and Facebook Marketplace never ask. Poshmark's label is prepaid by the buyer's flat shipping fee, and Facebook local pickup has no shipping at all.
Why we ask for the label cost
On eBay and Depop, you set a shipping price on the listing, the buyer pays it, and then you buy the label yourself after the sale. The label almost never costs exactly what the buyer paid. If it cost less, you made a little extra; if it cost more, that loss is real, and belongs in your numbers.
The shipping price you charged is already inside Sold for the moment the sale is recorded: the row shows "incl." and the shipping amount underneath. The only missing fact is what the label cost you, and only you know that, at the moment you buy it. That's the one number we ask for.
Until you enter a label cost, we count it as $0, the same way a missing item cost works, so your profit reads a little high rather than waiting on you. It corrects itself the moment you type the number.
1. Enter label costs from the reminder
The fastest way is the reminder on the Sales overview:
- Click Sales in the top menu. If any recent eBay or Depop sales are missing a label cost, the Needs attention card says so.
- Click Add label costs. You land on exactly those sales, with the Shipping label column showing Add cost on each row.
- Click Add cost on a sale.
- Type what the label cost, like
14.85. - Click Save.

The sale's profit updates, and it drops off this list.
2. Enter or correct a label cost any time
- Click Sales in the top menu, then the All sales tab.
- Click Columns, and tick Shipping label.
- Click Add cost on any sold sale, or click an existing amount to correct it.
- Type the amount, or clear the field to remove it.
- Click Save.
You can also click the pencil on a sale's row: Edit this sale has a Shipping label field.

Several items in one box? Enter the label once, on any of them. RelistKit splits it across the bundle's items by price.
What if I never enter it?
Nothing breaks. These figures stay complete either way:
- your sales
- your revenue
- what you keep from each sale
Only the profit on those sales reads high, by the label amount. The reminder covers sales from the last 90 days, so old history never nags you. Older sales can still be filled in through the Shipping label column whenever you feel like tidying up.
Where these numbers show up
- All sales: the optional Shipping charged column (the shipping part of what the buyer paid) and the Shipping label column, both under Columns. Both are in the CSV and Excel downloads too.
- Profit, everywhere: label costs come off profit in the monthly chart, the Overview tiles and the Platforms tab.
- Reports: your profit and loss has a Shipping labels line (see The Profit and Loss).
- Consignors: when a consignor's share is a percentage of net profit, the label comes off before the split.
Common questions
I entered the wrong amount.
- Click Sales, then the All sales tab.
- Click the amount in the Shipping label column.
- Type the right number, and click Save.
Does a Poshmark sale ever need a label cost?
No. The buyer's flat fee prepays the label, so the cost is $0 and the column stays empty.
I bought the label through eBay, and eBay took it from my payout. Do I still enter it?
Yes. RelistKit doesn't read label purchases from eBay, so enter it like any other label.
I shipped a Facebook or cash sale.
Add the label in the Shipping label column. There's just no reminder for those.
Should I also log the label as an expense?
No: that would count it twice. The Shipping and packaging expense category is for supplies, like mailers and tape, and labels bought outside a sale.
I paid for a return label.
Enter it when you record the refund. It counts with your label costs (see Refunds and Returns).
