Serial number traceability on Smooth 4 turns a recall from a crisis into a routine task.
Between the factory gate and the retail shelf, serial number traceability is where most of the value on the Smooth 4 is either created or lost.
Retail staff rarely ask about serial number traceability directly, but their questions almost always lead back to it.
Why serial number traceability matters on the Smooth 4
Batch identifiers should appear on the unit, the inner tray and the master carton.
A written internal standard for serial number traceability makes onboarding new account managers far quicker and reduces avoidable errors.
A simple spreadsheet linking batch to destination account is usually sufficient at this scale.

Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

| Carton (174 units) | Tier 1 | 14-21 days |
| Pallet (576 units) | Tier 2 | 14-21 days |
