Packing without errors: verify, pack, weigh and label

November 13, 2026 · 7 min read

Packing is the last time anyone in the warehouse has the order in their hands. Whatever goes across the table unchecked reaches the buyer as it is: with a swapped item, with one unit short or with somebody else's label. This article explains what is done in packing, how to organize the packing table and what to check at each step —verify, pack, weigh and label— so that no errors go out.

What packing is in a warehouse

It is the stage between picking the order and its departure. The picker has collected the items from the racks and left them at the table, normally in a tote or on a cart. In packing you check that this is what the order asked for, pack it, close the parcel and put the carrier label on it. The parcel then moves to the dispatch area.

The four steps have an order and it is worth respecting:

Step	What is done	What is checked
1. Verify	Each item is scanned against the order	That the item and the quantity are the ones ordered; batch or serial number if they are tracked
2. Pack	The box or mailer is chosen, the goods are protected and it is closed	Right size, enough protection, the client's instructions
3. Weigh	The closed parcel is weighed	That the real weight is close to the expected one and is the one declared to the carrier
4. Label	The label is requested from the carrier, printed and stuck on	That the label is the one for that order and goes on that parcel

How to verify the order before closing the box

Verifying means going over, item by item and with the scanner, that what is on the table is what the order asks for. It is a second check on the picking, done by another person or, at least, at another moment: if the picker took a similar item or one unit short, this is where it shows.

For it to be useful, it has to be mandatory and not depend on the rush: the software should not let the box be closed until every unit has been scanned. When an order has many units of the same item, the reasonable thing is to scan one and count the rest, not to pass the scanner forty times.

If something is missing at verification, the order is not closed “to complete it later”: it is set aside, reported and resolved. Where those failures come from and how to cut them earlier is covered in how to reduce picking errors.

How to pack: box, protection and what the client asks for

→The box or mailer, just the right size. A box that is too big forces you to fill it and can cost more with the carrier, which usually takes volume into account as well as weight; one that is too small arrives burst.
→Protection according to the product: fragile goods, away from the walls of the box; liquids, upright and with the cap checked; heavy goods, at the bottom.
→What each client or each store asks for: delivery note inside or not, a return sheet, branded wrapping, no third-party advertising. It has to be written down and visible at the table, not in the packer's memory.
→Firm closure with tape, with no old labels or barcodes from other shipments in view.

If the order does not fit in one box, it is split into several parcels and each one carries its own label. It is worth recording which items go in each parcel: it is the first thing asked when the buyer says only part of it has arrived.

Why weigh the parcel

The weight has two functions. The first is declaring the right figure to the carrier: if the real weight is above the declared one, the carrier can adjust it later on the invoice. The second is control: if the weight of each item is known, the closed parcel has an expected weight, and a large difference warns that something is missing or extra inside.

That control is only as good as the weights in the item records. With items that have no weight in the catalog, the expected weight is no use for comparing, so before making weighing mandatory it is worth completing that data.

What the carrier label carries and how not to get it wrong

The label is generated by the carrier from the order data: recipient, address, service, shipment number with its barcode and, depending on the case, weight and parcel number. Labeling errors are almost never in the content of the label, but in which parcel it is stuck on.

→Request the label from the order, when closing the parcel, and not by copying the address into the carrier's website.
→Print it at the table itself and stick it on right away: a printed label that waits is a label that ends up on another parcel.
→One order at a time on the table. Two orders open at once are a common cause of crossed labels.
→In shipments with several parcels, one label per parcel and all of them stuck on before moving to the next order.
→Stick it on the largest, smooth face, without the tape covering the barcode.

What to do when something does not match at the table

The table is a checkpoint, so it needs a planned way out for whatever does not pass the check. If a unit is missing, if an item is not the one ordered or if it comes damaged from the rack, the order is set aside in a marked place, reported and not mixed with the ones in progress. What must never happen is the packer going to the rack to “fix it” without it being recorded: the order goes out right, but the stock is left wrong and the next picker runs into the problem.

The same goes for the label: if the carrier does not return a label because the address is incomplete or the postal code does not exist, the closed parcel waits in an incident area with its order identified, not in the outbound pile.

How to organize the packing table

A well set-up packing table saves steps and prevents mix-ups. What it needs within reach:

→A clear surface for a single order.
→Barcode scanner and screen or PDA, at eye level and without taking up the table.
→Label printer within reach, without having to get up.
→Boxes and mailers in the most used sizes, sorted by size; filler and tape.
→A scale, if you weigh.
→Separate way in and way out: the totes with orders to pack arrive on one side and the finished parcels leave on the other, toward their carrier's zone.

In peak season, when orders multiply, the table is where the queue forms first; how to prepare it is in how to get your warehouse ready for peak season.

What to track in packing

→Orders that reach the table incomplete or with a wrong item: they measure the quality of the picking.
→Orders packed per person and hour, to know how many tables are needed.
→Orders waiting at the table close to their carrier's pickup time.
→Incidents that come back from the buyer —wrong item, one unit missing, arrived broken— and which table they left from.

The formulas for these indicators are in the warehouse KPIs that really matter.

How we do it at Ubika

In Ubika, “Pack” is a PDA task. At the table each item of the order is scanned; with one unit scanned, the rest of the same item can be counted as done. The software does not let the parcel be closed until every unit is verified: nothing is packed blind. The screen shows how the client wants the order packed, and a photo of the closed parcel can be saved in the order. If the workflow includes quality control, nothing is packed without its approval.

On packing, Ubika requests the shipment from the carrier and its label comes out, ready to print and stick on; it can be printed at the table or at the dock. While the carrier is not connected, the label is a test one and says so in large letters. Weighing is optional: if the weight of the parcel is entered, it is validated against the estimate from the catalog; if not, the estimate is used. Each parcel gets its license plate when it is packed, which, if the warehouse tracks every parcel, is scanned at each step all the way to the truck, and the order moves to shipped when the driver signs the pickup; that last stretch is in the PDA at dispatch.

Frequently asked questions

What is packing in a warehouse?

It is the stage in which the order that has already been picked is checked, packed, weighed and labeled for the carrier. It comes after picking and before dispatch, and it is the last point where an error can be corrected before the order leaves.

What is the difference between picking and packing?

Picking is collecting from the racks the items the order asks for. Packing is what is done afterwards at the table: verifying that what was picked is what was ordered, putting it in the right box, closing it and putting the shipping label on it.

How do you avoid packing errors?

By scanning each item at the table against the order before closing the box, working on one order at a time, requesting the carrier label from the order itself —not copying addresses by hand— and sticking it on the moment it comes out.

Is it necessary to weigh every parcel?

It depends on the carrier and the type of product. The weight serves two purposes: declaring the right figure to the carrier and detecting that something is missing from or extra in the box when the real weight is far from the expected one. If you do not weigh, you work with the weight estimated from each item's record.

What should a packing table have?

Free surface for one order, a barcode scanner, a screen or PDA, a label printer, boxes and mailers in the usual sizes within arm's reach, filler, tape and, if you weigh, a scale. And a clear exit area for finished parcels.

What information is on the carrier label?

The recipient and their address, the sender, the service contracted, the shipment number with its barcode and, depending on the carrier, the weight and the parcel number within the shipment (1 of 2, 2 of 2). The carrier generates it from the order data.
