How to sort shipping labels by SKU and courier (pack faster, fewer errors)

29 May 20267 min readBy The ShipWorks team

Most sellers focus on cropping their labels to thermal size — and stop there. But the step that actually saves the most time on a busy day isn't cropping, it's sorting. Printing labels in the right order — grouped by SKU and by courier — turns a chaotic packing session into an assembly line. This post explains both sort types, when to use each, and how to do it automatically.

Why sorting wins

SKU-wise sort → pick one product at a time, no running back and forth.
Courier-wise sort → hand each courier a grouped stack, faster manifest and pickup.
Both together → fewer mis-ships, faster dispatch, lower late-dispatch risk.

Why label order matters at scale

Marketplace label PDFs arrive in whatever order the seller panel dumped them — random SKUs, random couriers. Print that raw and your packer bounces around the shelves, re-checks each label, and sorts parcels by courier at handover. On 5 orders that's fine. On 150, that disorganisation is where the hour goes — and where mis-ships happen.

SKU-wise sorting: pick once, pack many

Sorting labels by SKU groups all orders for the same product together. Your packer pulls that product once, packs every order that needs it, then moves to the next SKU. No walking back to the same shelf ten times, and far less chance of putting the wrong item in a parcel.

Best when you sell many units of a few SKUs.
Cuts picking time and reduces wrong-item returns/RTO.

Courier-wise sorting: faster handover

Sorting by couriergroups all parcels going with the same partner. At pickup you hand each courier its complete, grouped stack — manifests reconcile faster and fewer parcels get mis-scanned or left behind. This is the same idea behind “pickup sort”.

Which sort comes first?

Your situation	Sort priority
Few SKUs, high quantity each	SKU first, then courier
Many SKUs, multiple couriers	Courier first, then SKU within courier
Single courier, varied catalogue	SKU sort is the big win

A good tool lets you sort by both at once — courier groups, SKU-ordered within each.

Doing it manually vs automatically

You can sort manually by reordering PDF pages — but it's slow, breaks the moment a new batch comes in, and free crop-only tools don't do it at all. Automatic sorting reads the courier and SKU off each label and reorders the whole batch in seconds, every time.

ShipWorks crops to thermal size, removes the invoice, and sorts by courier + SKU in a single pass for Meesho, Flipkart, and Amazon — drop one PDF, get back a sorted, thermal-ready file. See it inside the full bulk flow in how to print Flipkart labels in bulk and how to print Amazon labels in bulk.

Pair sorting with a picklist

Once labels are SKU-sorted, a picklist that totals quantity per SKU lets you pull stock for the whole batch in one trip — then pack straight down the sorted stack.

FAQs

Q: What does SKU-wise sorting mean?

It means ordering your shipping labels so all orders for the same product (SKU) are grouped together. Your packer pulls that product once and packs every order needing it, instead of walking back to the same shelf repeatedly.

Q: Why sort labels by courier?

Courier-wise sorting groups parcels by delivery partner so you hand each courier a complete stack at pickup. Manifests reconcile faster and fewer parcels are mis-scanned or missed.

Q: Can I sort by SKU and courier at the same time?

Yes. A crop + sort tool like ShipWorks groups by courier and orders by SKU within each group in one pass, so you get the benefit of both without manual reordering.
