Replacement Parts and Accessories, Made When They Sell
A spares catalogue is a long tail: a few parts sell, the rest wait in boxes. List every one, stock none, and have each made when it is ordered.
Replacement parts are the catalogue nobody wants to stock. A few sell every week; most sell a handful a year, and each one still needs a minimum order from a supplier. Printing spares on demand turns that around: every part is listed, none is on a shelf, and each is made when a customer orders it. With forty spare SKUs and a 250-unit minimum, stocking them all ties up $15,000 before anything sells, and 35 of the 40 never sell through their first order. Put your own catalogue in:
Stocked at the minimum
$15,000
up front, before a spare sells. 35 of 40 SKUs never sell their first order; 6,500 units ($9,750) are still on the shelf after 5 years.
Made as each one sells
$0
up front, then about $2.00 for each spare as it is ordered ($12,000 over 5 years for all 6,000), packed and shipped to the customer. Nothing left over, and a design change costs nothing to adopt.
The shape of every spares catalogue
A few parts sell. The long tail waits in boxes.
Why it mattersStock pays off only on the few SKUs at the left of the chart. Printing on demand pays off on all the rest.
What made-on-demand spares look like
- Every part listed
- Add each replacement part to your store with its SKU. The listing is the only inventory.
- Made when ordered
- The order reaches us through your store connection, matches the SKU, and is printed, checked and packed. It ships within three business days.
- Under your name
- Your business name and logo on the slip, nothing of ours in the box, and tracking back to your store.
- Fitted and assembled
- Choose assembly and a knob with a threaded insert, or a latch with a magnet and a pin, arrives as one finished part, for $1 a part.
- Revisions for free
- Improve a part and the next order prints the new file. No obsolete stock, no write-off, no new tooling.
Accessories work the same way
The same logic that suits spare parts suits accessories: the mount, the stand, the organiser insert, the colour variant that three per cent of customers want. Each one is a listing, not a pallet. A brand can test a new accessory with no stock at all, and only order a batch for the few that take off. Our Make-Cost Index prices thirty-six such parts live, and the low-volume buyer’s guide covers the batch.
When stocking still wins
The fastest movers at the left of the chart can be cheaper to hold, especially if they come out of a mould you already own. Many brands keep those in stock and send everything else to be printed on demand. The chart shows where that line falls for your catalogue: the SKUs whose bars clear the minimum-order line are the ones worth a batch.
FAQ
Yes. List each spare in your store with a SKU; when a customer orders one, it is printed, inspected, packed under your name and shipped to them. You hold no stock and pay the make cost only when a part sells.
For the long tail, usually. Stocking every SKU at a supplier’s minimum order ties up cash in parts that may never sell. In our example of forty SKUs with a 250-unit minimum, 35 never sell their first order. The few fastest movers can still be cheaper to stock.
Upload the new file and the next order prints it. There is no old stock to clear and no tooling to replace.
Yes. Magnets, heat-set inserts, screws and similar parts are added at the hardware’s own price, and fitted before it ships for $1 a part when you choose assembly.
Keep every spare in stock. Hold none of them.
Put each replacement part in your store with its SKU. When a customer orders one, it is printed, checked, packed under your name and shipped to them.
