Shipping is easy to ignore in a quiet month. A few orders, a few labels, and the postage feels like a rounding error. In the holiday rush the same small gaps repeat across every order: a box one size too big, a free-shipping threshold set from last year's rates, a gift order that ships in two parcels. Each one is small. Together they can take a real slice of your best sales month.
If you have not mapped what shipping costs you at all, read how to track your shipping and packaging costs first. This guide is the holiday version of the problem: more orders, bigger orders, and less time to check each one.
Know what each order actually paid
The number that matters is not a rate table. It is the postage you actually paid on each order, set next to what the buyer paid for shipping. The gap between the two is a cost of that sale, the same as materials. If you only look at shipping as a monthly total, you cannot see which products, box sizes or destinations are losing money.
Re-check your free-shipping math before the rush
Free shipping is not free. Its cost has to come out of the product price. Before the season starts, check that the postage built into your prices still matches what labels cost today. Carriers adjust rates from time to time and some add peak-season surcharges, so confirm current rates with your carrier rather than relying on last year's numbers.
- Free-shipping threshold: does an order at your threshold still cover typical postage, with margin left over?
- Flat-rate shipping: does your flat charge cover the heavier, multi-item orders that holiday buyers place?
- Gift sets: a set ships heavier and larger than a single item. Price its shipping on its own weight and box.
Pick boxes on purpose
Package size often matters as much as weight. A box a little bigger than it needs to be can push a parcel into a more expensive price band, and it uses more filler. Before the rush, settle on a short list of boxes that fit your common orders, weigh a packed example of each, and write it down so anyone packing uses the same one.
In December the box is not just packaging. It is a price decision you make every time you pack an order.
Plan for multi-item and late orders
- Combine before you ship. Two orders from the same buyer on the same day can often go in one parcel. Check before you print two labels.
- Avoid split shipments. Shipping half an order now and half later pays postage twice. If you split, know why.
- Know your last ship dates. Carriers publish holiday cut-off dates each year. Put them on your listings so late buyers choose faster shipping knowingly, and never promise what the carrier cannot deliver.
- Faster shipping is a price, not a favour. If a buyer needs it by a date, charge for the faster service.
A pre-season shipping checklist
- Pull last season's orders and note the most common item combinations.
- Choose the box for each common combination and weigh a packed example.
- Check current postage for those weights and sizes with your carrier.
- Compare that postage with what your listings charge for shipping or build into the price.
- Adjust free-shipping thresholds and flat rates wherever the gap is negative.
- Stock enough boxes and filler for your forecast order volume.
- Add your carriers' holiday cut-off dates to your listings and order notes.
From the Maker plan, Keepsel lets you list the shipping and packaging items each product goes out in, so their cost is part of its true cost before you set a price, and a product or box size that loses money on postage shows up while there is still time to fix it.
