Eight months later, the customer is back

The conversation nobody wins

A customer returns with a failing appliance and a bill from eight months ago. The bill names a model. The manufacturer's warranty desk wants a serial number, a purchase date and confirmation it came through an authorised dealer.

The shop can produce two of those three. What follows is either an afternoon spent matching delivery notes against a rough purchase window, or the shop absorbing a repair it should not have paid for. Most shops absorb it, because the customer is standing in front of them and the alternative is an argument.

There is only one place to capture it

Serials have to be captured when goods are received, not when they are sold. At the point of sale the box is on the counter and the queue is waiting, and anything that requires opening a carton to read a label will not happen consistently.

Captured at receiving, each unit has an identity from the moment it enters the shop, and the sale simply attaches a customer to a unit that already exists.

Do not do this to everything

Serialising accessories is a waste of time. Cables, chargers, mounts and batteries are not individually identifiable in any way the manufacturer cares about, and tracking them per unit adds work that returns nothing.

The categories worth serialising are the ones with a manufacturer warranty and a meaningful repair cost. In most shops that is a minority of lines and the large majority of warranty exposure.

The case nobody plans for

The unglamorous benefit shows up when a model develops a known fault and the manufacturer issues a batch-specific notice. A shop with serials against sales can tell which of its customers bought an affected unit and contact them.

A shop without them can either contact everyone who bought that model, which is alarming and expensive, or contact nobody and wait.
