The Barcodes You Have, and the Ones You'll Make

Start with what's already there

Walk your shelves and you'll find three kinds of stock.

Some of it arrives with a usable barcode printed on the box by the manufacturer. Filters, plugs, boxed electrical, most branded consumables. You don't need to label these. You need to tell your system that this barcode means this part, once, and then it works forever.

Some of it arrives with a barcode you can't use — a carton code that covers a box of forty, a supplier's internal code that changes between orders, or a label that's on the outer packaging you throw away.

And a lot of it arrives with nothing. Bulk hardware, hoses, seals, anything loose, anything you break down and sell in ones.

The first pass through your stock is just sorting it into those three piles. It's a morning's work with a scanner, and it tells you how much printing you are actually in for. Most businesses find it's a lot less than they feared, because the fast-moving branded stuff — the lines the counter hits fifty times a day — is usually already barcoded.

The decision to get right before you print anything

Which number is your number?

In auto and truck parts, a single physical item can carry the OEM number, the aftermarket manufacturer's number, one or two supplier codes, and whatever your business has called it since before the current system. They are all legitimate and people will walk up to your counter asking for any of them.

The mistake is trying to pick a winner. You don't need one primary number. You need one primary record, with every other number attached to it as a cross-reference, so that scanning any of them — or typing any of them — lands on the same part.

Get this right before you print a single label. Relabelling a shelf is annoying. Discovering six months in that you have two live records for the same bearing, with stock and history split across both, is a genuinely expensive afternoon.

A working rule: your primary record uses the number your buyer orders against, because that's the one that has to match a supplier invoice. Everything the counter gets asked for goes on as a cross-reference.

Label the place, not just the part

This is the bit people skip, and it's the one that pays fastest.

Barcode your bins, racks and shelves. A location label costs almost nothing and takes a second to scan, and it converts your stock system from a list of what you own into a map of where it is.

Once locations are scanned:

• Putting stock away records where it went, so the next person can find it.
• A count is "scan the bin, scan what's in it" — no clipboard, no transcription.
• A part can live in two places on purpose (bulk on the high racking, a pick face at the counter) and the system knows about both.
• New staff can find stock on their first morning without interrupting anyone.

If you only do one thing from this article, do locations. It's the cheapest labelling you'll ever print and the only one your counter staff will thank you for in the first week.

What to label first

Not everything. Please, not everything.

The instinct is to start at aisle one and work through to the end, and it's the reason a lot of labelling projects die in aisle four. Sequence it by what it's worth instead:

First, your locations. All of them. This is the one place where doing the whole thing up front is right, because a half-mapped warehouse is worse than an unmapped one.

Then your fast movers. The few hundred lines that make up most of your counter traffic. These deliver nearly all of the benefit and they're usually the ones already carrying manufacturer barcodes, so it's mostly matching rather than printing.

Then your expensive lines. Low volume, high value. You're not doing these for speed, you're doing them because a variance on one of them costs more than a week of variances on washers.

Then the long tail, as you touch it. Print the label when the part is picked, received or counted — not in a dedicated labelling drive. The slow movers get labelled over a few months by the ordinary running of the business, which is the only way that work ever actually gets done.

Anything that never moves and isn't worth much can stay unlabelled for a good while. It isn't where your money is going.

Printing on the spot

There's a practical reason we bring a label printer to demos rather than talking about one.

Labelling stops being a project the moment printing is something that happens at the shelf, in the flow of ordinary work. Part arrives with no barcode? Print one now, stick it on, put it away. Bin gets reorganised? Print the new location label standing in front of it.

If printing means writing a list, walking to an office, batching a print run and walking back, it will be done in bursts when someone has time, which in a busy parts business means it will be done twice and then abandoned.

Two things worth knowing before you buy anything: get labels rated for the environment they live in — oil, sunlight through a roller door and cold storage all destroy the wrong adhesive — and put the barcode where a scanner can actually reach it, not on the underside of something heavy.

What this looks like when it's working

A part arrives. It's scanned in against a purchase order, so the quantity is checked at the door rather than assumed. It's put away with a scan, so the system knows the bin. A customer asks for it by an OEM number your business has never used, and it comes up anyway because that number is a cross-reference on the record. The counter salesman reads the bin off the screen and walks straight to it. The pick is a scan, so the stock record moves the moment the part does.

None of the individual steps are impressive. That's rather the point — the whole thing is a series of small frictions removed, and the result is a count you believe and a counter that's faster on a busy Saturday.

If you want to see what that looks like on your own stock rather than in a paragraph, that's what the demo kit is for. We bring the scanners and the printer, label a shelf of your parts, and you run it yourself.
