Two-bin kanban for small shops

You didn't start your shop to waste time ordering supplies.

You started it to build something. But somehow you're the only one who knows what to reorder, where to buy it, or how much — and the whole place stops when you're not on it. TwoBin takes the dumbest job in the building off your plate and turns it into a system your whole team can run.

A TwoBin kanban card: part photo, reorder quantity, location and a QR code to scan when the bin runs empty

You know this shop.

The toolbox stash.Your best people hoard grinding discs in their drawers — hundreds of dollars of supplies — because they don't trust the shop won't run out.
The Monday supply run.A crew is headed to the field and there are no cutting discs. So it's your card and a Home Depot run before the job can start.
The sticky note.“We're out. Need 10 today.” Stuck to your desk, again.
The $1 part.It just stopped a $200-an-hour crew.

None of this is a people problem. It's a system problem. You just never had time to build the system.

Not inventory software

A system for never running out.

You don't need to count and barcode every screw like you're running a warehouse. Counting is for the things you sell. TwoBin is for the stuff that quietly keeps your shop running — consumables, hardware, the supplies nobody thinks about until they're gone.

That's what a two-bin system does. One bin in use, one in reserve. When the first runs empty, someone scans its card — and the reorder is on its way while the team keeps working out of the reserve.

The front bin empties.

Your team keeps working out of the reserve bin. No interruption.

Scan the card.

One scan from any phone puts the part on the reorder list.

Order and receive.

Purchasing sees what's needed, grouped by vendor. Receive it and it goes back to its bin.

You never think about it.

No counting, no guessing, no Monday runs.
What's inside

The reason you're the bottleneck is there's no system. So we built the system.

Kanban cards with a photo

Anyone can print a card for any part. No more “only the owner knows how to make a label.”

Warehouse layout

Map your space — area, row, rack, shelf, bin — and print every location label you need.

Scan on the floor

Any phone. An empty bin becomes a reorder in one scan.

Purchasing that's ready to go

Everything that needs ordering, grouped by vendor, with purchase orders when you want them.

Receiving and put-away

Receive what came in and the system tells you exactly where it goes.

A parts catalog to start fast

Add common shop supplies from a ready-made catalog instead of typing every part in.

Every one of these was a job that used to stop with you. Now it doesn't.

Why TwoBin exists

Kanban was where it started.

I didn't come to lean from a business school. I came to it from a shop floor — mine — standing in a building I was proud of, watching it drift toward the kind of disorganized place I never wanted it to become.

So I went looking for shops that had figured it out, and I found a whole world of them — running more volume, more parts, more chaos than mine, and doing it calmly. They weren't special. They found a reason, and they started. And at the center of almost every one of them was the same humble thing. Not a consultant. Not an expensive system. A card, a bin, and a simple rule about when to reorder.

Kanban became the first domino for us. Once the shelves stopped running out, my team stopped firefighting and started improving. Organized bins led to organized benches. Standard reorders led to standard work. The morning meeting, the projects, the people stepping up — all of it was built on that one system holding.

“Kanban won't transform your shop by itself. Nothing will. But it's the rooted core you can build everything else on top of.”Jonathan Duke, founder
Built in a real shop

The road map I wish someone had handed me.

TwoBin came out of a 12,000 sq ft fabrication shop in Texas, not a software company. It exists to make that system stick — the same simple two-bin loop your team already understands, built to run every day on a real floor.

Everything can always be improved.
