Barcode for bakery products: label a box of six for the till

Give each product in each box size its own barcode number, print it on a label away from grease and the date, and add it to your billing software. The number stays the same every batch; only the date label changes.

What a barcode for bakery products does

A barcode on a bakery box does one job. It scans at the till and tells your billing software which item is in the customer's hand. The software then pulls up the name and the price. That is the whole trick.

It does not carry the bake date. It does not say the box is fresh. It does not change when the price changes. The number points to a line in your item list, and everything else lives in that list or on a separate label.

This matters for a bakery or sweet shop more than most. Your stock turns over in two to five days, your boxes come in several sizes, and in festival week the counter is three deep. A barcode that is set up right makes that week shorter.

One number per item, per box size

The rule is simple. Each thing a customer can pick up and pay for as one unit gets its own number.

A box of six cupcakes is one item. A box of twelve of the same cupcakes is a second item. A single cupcake sold loose from the glass is a third, if you scan it at all. Kaju katli in a 250 g box and in a 500 g box are two items. A gift hamper with three boxes inside is one more item, with its own number on the outside.

What stays the same is the recipe across batches. Monday's box of six and Thursday's box of six carry the same number. You do not need a new barcode each time you bake.

To count what you need, walk the shelf with a notebook. Write each product down once for every size you pack it in. A small bakery with 15 products in two box sizes needs 30 numbers. Add the festival gift boxes you plan to make, then add five or ten spare for new items in the year. Most shops land between 30 and 60.

Shelf life: keep the date off the barcode

Short shelf life tempts people to put the date into the barcode. Do not. The number names the product; the date belongs on its own small label or a stamp.

The working setup in most bakeries is two labels on each box. The first is printed once in a large roll and carries the barcode and the product name. The second is printed each morning with the packed-on date, the best-before date and the MRP. If you change the MRP in Diwali week, you reprint only the small label and update the price in your billing software. The barcode roll does not change.

Keep the two labels apart by at least a finger's width. A scanner reads better when there is clear space around the bars, and staff can find the date at a glance.

Labels that survive the kitchen and the fridge

Bakery boxes are hard on labels. Butter, sugar syrup and fridge condensation all lift paper and smear ink. A few choices fix most of it.

Put the label on the lid or the side of the box, never on the tray that touches the food. Grease soaks through card from the inside in an hour or two.

For items that go into a chiller, buy labels sold for cold or freezer use. The glue is different, and an ordinary label will curl at the corners by the second day.

A direct thermal printer is fine for a bakery. Those labels fade over months in sunlight, but your boxes are gone in days. A 50 × 25 mm label holds the barcode, the name and a little space. Print the bars at full size, not shrunk to fit; a squeezed barcode is the most common reason a till beeps twice.

Do not wrap a label around a sharp corner or across the fold of a box. The bars must sit flat. On a round tin, run the bars up and down, the same way as the side of the tin, so they do not curve away from the scanner.

The barcode guide has the sizes and the clear space a scanner needs, if you want to check your label layout before you print a full roll.

Getting ready for festival week

Festival week is when the setup pays for itself. Three things help.

First, decide your gift boxes two weeks early. Each mix you sell as one box needs a number before the labels can print. A box of assorted sweets in 500 g and 1 kg is two items. Give each a clear name in your software, such as "Assorted 1 kg gift box", so staff do not pick the wrong line.

Second, print the barcode labels a week ahead and stick them on flat boxes before you fold them. One person can label 200 flat boxes in an hour. Folded boxes take twice as long.

Third, test every new roll. Take the first label off, stick it on a box and scan it at the till. Check the name and the price on screen. If it is right, label the rest. If not, you have lost one label, not a day of packing.

Keep a printed sheet near the till with the barcode for your ten fastest-selling boxes. When a label tears or gets wet, the cashier scans the sheet and the queue keeps moving.

Setting it up this afternoon

Here is the order of work. Make the item list from your notebook: one line per product per size. Choose a pack of EAN-13 numbers a little larger than your count; the packs and prices page shows every size. When the files arrive, give one number to each line and write it into your billing software next to the item name. Print one test label per item, scan each one, and fix any line that shows the wrong name. Then print the rolls.

If you also plan to sell your boxes through a shop chain, an online store or a delivery app, tell us where you sell. We will tell you which number suits that channel before you print.

When you add a new item

A new cake, a new box size or a new festival mix each takes the next spare number from your list. Note it in the item list on the same day, so two products never share one. Numbers you stop using can sit idle. Do not hand an old number to a different product for at least a year, so old boxes still on a shelf somewhere do not scan as the new item.

Order the EAN-13 numbers for your counter on the EAN-13 packs page.
